Mr. Meany is driving your success and the - network continues to grow thanks to the hard work Christine has done. You recently - hired Stanley Soroka as manager of information systems. Christine recommended Stan - to the role. She told you Stan is so good at handling Samba that he can make a cast - iron rocking horse that is embedded in concrete kick like a horse at a rodeo. You - need skills like his. Christine and Stan get along just fine. Let's see what - you can get out of this pair as they plot the next-generation networks. - </p><p> - Ten months ago Abmas closed an acquisition of a property insurance business. The - founder lost interest in the business and decided to sell it to Mr. Meany. Because - they were former university classmates, the purchase was concluded with mutual assent. - The acquired business is located at the other end of town in much larger facilities. - The old Abmas building has become too small. Located on the same campus as the newly - acquired business are two empty buildings that are ideal to provide Abmas with - opportunity for growth. - </p><p> - Abmas has now completed the purchase of the two empty buildings, and you are - to install a new network and relocate staff in nicely furnished new facilities. - The new network is to be used to fully integrate company operations. You have - decided to locate the new network operations control center in the larger building - in which the insurance group is located to take advantage of an ideal floor space - and to allow Stan and Christine to fully stage the new network and test it before - it is rolled out. Your strategy is to complete the new network so that it - is ready for operation when the old office moves into the new premises. - </p><div class="sect2" title="Assignment Tasks"><div class="titlepage"><div><div><h3 class="title"><a name="id336038"></a>Assignment Tasks</h3></div></div></div><p> - The acquired business had 280 network users. The old Abmas building housed - 220 network users in unbelievably cramped conditions. The network that - initially served 130 users now handles 220 users quite well. - </p><p> - The two businesses will be fully merged to create a single campus company. - The Property Insurance Group (PIG) houses 300 employees, the new Accounting - Services Group (ASG) will be in a small building (BLDG1) that houses 50 - employees, and the Financial Services Group (FSG) will be housed in a large - building that has capacity for growth (BLDG2). Building 2 houses 150 network - users. - </p><p> - You have decided to connect the building using fiber optic links between new - routers. As a backup, the buildings are interconnected using line-of-sight - high-speed infrared facilities. The infrared connection provides a - secondary route to be used during periods of high demand for network - bandwidth. - </p><p> - The Internet gateway is upgraded to 15 Mb/sec service. Your ISP - provides on your premises a fully managed Cisco PIX firewall. You no longer need - to worry about firewall facilities on your network. - </p><p> - Stanley and Christine have purchased new server hardware. Christine wants to - roll out a network that has whistles and bells. Stan wants to start off with - a simple to manage, not-too-complex network. He believes that network - users need to be gradually introduced to new features and capabilities and not - rushed into an environment that may cause disorientation and loss of productivity. - </p><p> - Your intrepid network team has decided to implement a network configuration - that closely mirrors the successful system you installed in the old Abmas building. - The new network infrastructure is owned by Abmas, but all desktop systems - are being procured through a new out-source services and leasing company. Under - the terms of a deal with Mr. M. Proper (CEO), DirectPointe, Inc., provides - all desktop systems and includes full level-one help desk support for - a flat per-machine monthly fee. The deal allows you to add workstations on demand. - This frees Stan and Christine to deal with deeper issues as they emerge and - permits Stan to work on creating new future value-added services. - </p><p> - DirectPointe Inc. receives from you a new standard desktop configuration - every four months. They automatically roll that out to each desktop system. - You must keep DirectPointe informed of all changes. - </p><p><a class="indexterm" name="id336088"></a> - The new network has a single Samba Primary Domain Controller (PDC) located in the - Network Operation Center (NOC). Buildings 1 and 2 each have a local server - for local application servicing. It is a domain member. The new system - uses the <em class="parameter"><code>tdbsam</code></em> passdb backend. - </p><p> - Printing is based on raw pass-through facilities just as it has been used so far. - All printer drivers are installed on the desktop and notebook computers. - </p></div></div><div class="sect1" title="Dissection and Discussion"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id336113"></a>Dissection and Discussion</h2></div></div></div><p> - <a class="indexterm" name="id336121"></a> - The example you are building in this chapter is of a network design that works, but this - does not make it a design that is recommended. As a general rule, there should be at least - one Backup Domain Controller (BDC) per 150 Windows network clients. The principle behind - this recommendation is that correct operation of MS Windows clients requires rapid - network response to all SMB/CIFS requests. The same rule says that if there are more than - 50 clients per domain controller, they are too busy to service requests. Let's put such - rules aside and recognize that network load affects the integrity of domain controller - responsiveness. This network will have 500 clients serviced by one central domain - controller. This is not a good omen for user satisfaction. You, of course, address this - very soon (see <a class="link" href="happy.html" title="Chapter 5. Making Happy Users">“Making Happy Users”</a>). - </p><div class="sect2" title="Technical Issues"><div class="titlepage"><div><div><h3 class="title"><a name="id336141"></a>Technical Issues</h3></div></div></div><p> - Stan has talked you into a horrible compromise, but it is addressed. Just make - certain that the performance of this network is well validated before going live. - </p><p> - Design decisions made in this design include the following: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - <a class="indexterm" name="id336161"></a> - <a class="indexterm" name="id336168"></a> - <a class="indexterm" name="id336174"></a> - A single PDC is being implemented. This limitation is based on the choice not to - use LDAP. Many network administrators fear using LDAP because of the perceived - complexity of implementation and management of an LDAP-based backend for all user - identity management as well as to store network access credentials. - </p></li><li class="listitem"><p> - <a class="indexterm" name="id336188"></a> - <a class="indexterm" name="id336195"></a> - Because of the refusal to use an LDAP (ldapsam) passdb backend at this time, the - only choice that makes sense with 500 users is to use the tdbsam passwd backend. - This type of backend is not receptive to replication to BDCs. If the tdbsam - <code class="filename">passdb.tdb</code> file is replicated to BDCs using - <code class="literal">rsync</code>, there are two potential problems: (1) data that is in - memory but not yet written to disk will not be replicated, and (2) domain member - machines periodically change the secret machine password. When this happens, there - is no mechanism to return the changed password to the PDC. - </p></li><li class="listitem"><p> - All domain user, group, and machine accounts are managed on the PDC. This makes - for a simple mode of operation but has to be balanced with network performance and - integrity of operations considerations. - </p></li><li class="listitem"><p> - <a class="indexterm" name="id336229"></a> - A single central WINS server is being used. The PDC is also the WINS server. - Any attempt to operate a routed network without a WINS server while using NetBIOS - over TCP/IP protocols does not work unless on each client the name resolution - entries for the PDC are added to the <code class="filename">LMHOSTS</code>. This file is - normally located on the Windows XP Professional client in the - <code class="filename">C:\WINDOWS\SYSTEM32\ETC\DRIVERS</code> directory. - </p></li><li class="listitem"><p> - At this time the Samba WINS database cannot be replicated. That is - why a single WINS server is being implemented. This should work without a problem. - </p></li><li class="listitem"><p> - <a class="indexterm" name="id336261"></a> - BDCs make use of <code class="literal">winbindd</code> to provide - access to domain security credentials for file system access and object storage. - </p></li><li class="listitem"><p> - <a class="indexterm" name="id336279"></a> - <a class="indexterm" name="id336288"></a> - Configuration of Windows XP Professional clients is achieved using DHCP. Each - subnet has its own DHCP server. Backup DHCP serving is provided by one - alternate DHCP server. This necessitates enabling of the DHCP Relay agent on - all routers. The DHCP Relay agent must be programmed to pass DHCP Requests from the - network directed at the backup DHCP server. - </p></li><li class="listitem"><p> - All network users are granted the ability to print to any printer that is - network-attached. All printers are available from each server. Print jobs that - are spooled to a printer that is not on the local network segment are automatically - routed to the print spooler that is in control of that printer. The specific details - of how this might be done are demonstrated for one example only. - </p></li><li class="listitem"><p> - The network address and subnetmask chosen provide 1022 usable IP addresses in - each subnet. If in the future more addresses are required, it would make sense - to add further subnets rather than change addressing. - </p></li></ul></div></div><div class="sect2" title="Political Issues"><div class="titlepage"><div><div><h3 class="title"><a name="id336318"></a>Political Issues</h3></div></div></div><p> - This case gets close to the real world. You and I know the right way to implement - domain control. Politically, we have to navigate a minefield. In this case, the need is to - get the PDC rolled out in compliance with expectations and also to be ready to save the day - by having the real solution ready before it is needed. That real solution is presented in - <a class="link" href="happy.html" title="Chapter 5.

To do this, create - the file <code class="filename">/etc/samba/smbusers</code> with the following contents: -</p><pre class="screen"> -#### -# User mapping file -#### -# File Format -# ----------- -# Unix_ID = Windows_ID -# -# Examples: -# root = Administrator -# janes = "Jane Smith" -# jimbo = Jim Bones -# -# Note: If the name contains a space it must be double quoted. -# In the example above the name 'jimbo' will be mapped to Windows -# user names 'Jim' and 'Bones' because the space was not quoted. -####################################################################### -root = Administrator -#### -# End of File -#### -</pre><p> - </p></li><li class="step" title="Step 6"><p> - Configure all network-attached printers to have a fixed IP address. - </p></li><li class="step" title="Step 7"><p> - Create an entry in the DNS database on the server <code class="constant">MASSIVE</code> - in both the forward lookup database for the zone <code class="constant">abmas.biz.hosts</code> - and in the reverse lookup database for the network segment that the printer is - located in. Example configuration files for similar zones were presented in <a class="link" href="secure.html" title="Chapter 3.

Use any other port the manufacturer specifies for direct mode, - raw printing. This allows the CUPS spooler to print using raw mode protocols. - <a class="indexterm" name="id337328"></a> - <a class="indexterm" name="id337335"></a> - </p></li><li class="step" title="Step 9"><p> - <a class="indexterm" name="id337348"></a> - Only on the server to which the printer is attached configure the CUPS Print - Queues as follows: -</p><pre class="screen"> -<code class="prompt">root# </code> lpadmin -p <em class="parameter"><code>printque</code></em> -v socket://<em class="parameter"><code>printer-name</code></em>.abmas.biz:9100 -E -</pre><p> - <a class="indexterm" name="id337382"></a> - This step creates the necessary print queue to use no assigned print filter. This - is ideal for raw printing, that is, printing without use of filters. - The name <em class="parameter"><code>printque</code></em> is the name you have assigned for - the particular printer. - </p></li><li class="step" title="Step 10"><p> - Print queues may not be enabled at creation. Make certain that the queues - you have just created are enabled by executing the following: -</p><pre class="screen"> -<code class="prompt">root# </code> /usr/bin/enable <em class="parameter"><code>printque</code></em> -</pre><p> - </p></li><li class="step" title="Step 11"><p> - Even though your print queue may be enabled, it is still possible that it - does not accept print jobs. A print queue services incoming printing - requests only when configured to do so. Ensure that your print queue is - set to accept incoming jobs by executing the following command: -</p><pre class="screen"> -<code class="prompt">root# </code> /usr/bin/accept <em class="parameter"><code>printque</code></em> -</pre><p> - </p></li><li class="step" title="Step 12"><p> - <a class="indexterm" name="id337455"></a> - <a class="indexterm" name="id337461"></a> - <a class="indexterm" name="id337468"></a> - This step, as well as the next one, may be omitted where CUPS version 1.1.18 - or later is in use. Although it does no harm to follow it anyway, and may - help to avoid time spent later trying to figure out why print jobs may be - disappearing without a trace. Look at these two steps as <span class="emphasis"><em>insurance</em></span> - against lost time. Edit file <code class="filename">/etc/cups/mime.convs</code> to - uncomment the line: -</p><pre class="screen"> -application/octet-stream application/vnd.cups-raw 0 - -</pre><p> - </p></li><li class="step" title="Step 13"><p> - <a class="indexterm" name="id337500"></a> - Edit the file <code class="filename">/etc/cups/mime.types</code> to uncomment the line: -</p><pre class="screen"> -application/octet-stream -</pre><p> - </p></li><li class="step" title="Step 14"><p> - Refer to the CUPS printing manual for instructions regarding how to configure - CUPS so that print queues that reside on CUPS servers on remote networks - route print jobs to the print server that owns that queue. The default setting - on your CUPS server may automatically discover remotely installed printers and - may permit this functionality without requiring specific configuration. - </p></li><li class="step" title="Step 15"><p> - As part of the roll-out program, you need to configure the application's - server shares. This can be done once on the central server and may then be - replicated using a tool such as <code class="literal">rsync</code>. Refer to the man - page for <code class="literal">rsync</code> for details regarding use. The notes in - <a class="link" href="secure.html#ch4appscfg" title="Application Share Configuration">“Application Share Configuration”</a> may help in your decisions to use an application - server facility. - </p></li></ol></div><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> - Logon scripts that are run from a domain controller (PDC or BDC) are capable of using semi-intelligent - processes to automap Windows client drives to an application server that is nearest to the client.

This necessitates that IP forwarding be enabled. This can be - achieved by adding to the <code class="filename">/etc/rc.d/boot.local</code> an entry as follows: -</p><pre class="screen"> -echo 1 > /proc/sys/net/ipv4/ip_forward -</pre><p> - To ensure that your kernel is capable of IP forwarding during configuration, you may wish to execute - that command manually also. This setting permits the Linux system to act as a router. - </p></li><li class="step" title="Step 2"><p> - This server is dual hosted (i.e., has two network interfaces) one goes to the Internet - and the other to a local network that has a router that is the gateway to the remote networks. - You must therefore configure the server with route table entries so that it can find machines - on the remote networks. You can do this using the appropriate system tools for your Linux - server or using static entries that you place in one of the system startup files. It is best - to always use the tools that the operating system vendor provided. In the case of SUSE Linux, the - best tool to do this is YaST (refer to SUSE Administration Manual); in the case of Red Hat, - this is best done using the graphical system configuration tools (see the Red Hat documentation). - An example of how this may be done manually is as follows: -</p><pre class="screen"> -<code class="prompt">root# </code> route add net 172.16.4.0 netmask 255.255.252.0 gw 172.16.0.128 -<code class="prompt">root# </code> route add net 172.16.8.0 netmask 255.255.252.0 gw 172.16.0.128 -</pre><p> - If you just execute these commands manually, the route table entries you have created are - not persistent across system reboots. You may add these commands directly to the local - startup files as follows: (SUSE) <code class="filename">/etc/rc.d/boot.local</code>, (Red Hat) - <code class="filename">/etc/rc.d/init.d/rc.local</code>. - </p></li><li class="step" title="Step 3"><p> - <a class="indexterm" name="id337688"></a> - The final step that must be completed is to edit the <code class="filename">/etc/nsswitch.conf</code> file. - This file controls the operation of the various resolver libraries that are part of the Linux - Glibc libraries.

An example of the execution of this script as well as its - validation are shown in Section 4.3.2, Step 5. - </p></li><li class="step" title="Step 5"><p> - <a class="indexterm" name="id337743"></a> - <a class="indexterm" name="id337750"></a> - <a class="indexterm" name="id337759"></a> - For each user who needs to be given a Windows domain account, make an entry in the - <code class="filename">/etc/passwd</code> file as well as in the Samba password backend. - Use the system tool of your choice to create the UNIX system account, and use the Samba - <code class="literal">smbpasswd</code> to create a domain user account. - </p><p> - <a class="indexterm" name="id337784"></a> - <a class="indexterm" name="id337790"></a> - <a class="indexterm" name="id337797"></a> - There are a number of tools for user management under UNIX, such as - <code class="literal">useradd</code>, <code class="literal">adduser</code>, as well as a plethora of custom - tools. With the tool of your choice, create a home directory for each user. - </p></li><li class="step" title="Step 6"><p> - Using the preferred tool for your UNIX system, add each user to the UNIX groups created - previously as necessary. File system access control is based on UNIX group membership. - </p></li><li class="step" title="Step 7"><p> - Create the directory mount point for the disk subsystem that is to be mounted to provide - data storage for company files, in this case, the mount point indicated in the <code class="filename">smb.conf</code> - file is <code class="filename">/data</code>. Format the file system as required and mount the formatted - file system partition using appropriate system tools. - </p></li><li class="step" title="Step 8"><p> - <a class="indexterm" name="id337856"></a> - Create the top-level file storage directories for data and applications as follows: -</p><pre class="screen"> -<code class="prompt">root# </code> mkdir -p /data/{accounts,finsvcs,pidata} -<code class="prompt">root# </code> mkdir -p /apps -<code class="prompt">root# </code> chown -R root:root /data -<code class="prompt">root# </code> chown -R root:root /apps -<code class="prompt">root# </code> chown -R bjordan:accounts /data/accounts -<code class="prompt">root# </code> chown -R bjordan:finsvcs /data/finsvcs -<code class="prompt">root# </code> chown -R bjordan:finsvcs /data/pidata -<code class="prompt">root# </code> chmod -R ug+rwxs,o-rwx /data -<code class="prompt">root# </code> chmod -R ug+rwx,o+rx-w /apps -</pre><p> - Each department is responsible for creating its own directory structure within the departmental - share. The directory root of the <code class="literal">accounts</code> share is <code class="filename">/data/accounts</code>. - The directory root of the <code class="literal">finsvcs</code> share is <code class="filename">/data/finsvcs</code>. - The <code class="filename">/apps</code> directory is the root of the <code class="constant">apps</code> share - that provides the application server infrastructure. - </p></li><li class="step" title="Step 9"><p> - The <code class="filename">smb.conf</code> file specifies an infrastructure to support roaming profiles and network - logon services. You can now create the file system infrastructure to provide the - locations on disk that these services require. Adequate planning is essential - because desktop profiles can grow to be quite large. For planning purposes, a minimum of - 200 MB of storage should be allowed per user for profile storage. The following - commands create the directory infrastructure needed: -</p><pre class="screen"> -<code class="prompt">root# </code> mkdir -p /var/spool/samba -<code class="prompt">root# </code> mkdir -p /var/lib/samba/{netlogon/scripts,profiles} -<code class="prompt">root# </code> chown -R root:root /var/spool/samba -<code class="prompt">root# </code> chown -R root:root /var/lib/samba -<code class="prompt">root# </code> chmod a+rwxt /var/spool/samba -</pre><p> - For each user account that is created on the system, the following commands should be - executed: -</p><pre class="screen"> -<code class="prompt">root# </code> mkdir /var/lib/samba/profiles/'username' -<code class="prompt">root# </code> chown 'username':users /var/lib/samba/profiles/'username' -<code class="prompt">root# </code> chmod ug+wrx,o+rx,-w /var/lib/samba/profiles/'username' -</pre><p> - </p></li><li class="step" title="Step 10"><p> - <a class="indexterm" name="id338048"></a> - <a class="indexterm" name="id338055"></a> - Create a logon script.

At this time, it does - not particularly matter which application server is used. It is necessary to manually - set a persistent drive mapping to the local applications server on each workstation at the time of - installation. This step is avoided by the improvements to the design of the network configuration - in the next chapter. - </p></li><li class="step" title="Step 5"><p> - Perform an administrative installation of each application to be used. Select the options - that you wish to use. Of course, you choose to run applications over the network, correct? - </p></li><li class="step" title="Step 6"><p> - Now install all applications to be installed locally. Typical tools include Adobe Acrobat, - NTP-based time synchronization software, drivers for specific local devices such as fingerprint - scanners, and the like. Probably the most significant application to be locally installed - is antivirus software. - </p></li><li class="step" title="Step 7"><p> - Now install all four printers onto the staging system. The printers you install - include the accounting department HP LaserJet 6 and Minolta QMS Magicolor printers, and you - also configure use of the identical printers that are located in the financial services department. - Install printers on each machine using the following steps: - </p><div class="procedure" title="Procedure 4.6.

Remember to install all - printers but to set the destination port for each to the server on the - local network. For example, a workstation in the accounting group should - have all printers directed at the server <code class="constant">BLDG1</code>. - You may elect to point all desktop workstation configurations at the - server called <code class="constant">MASSIVE</code> and then in your deployment - procedures, it would be wise to document the need to redirect the printer - configuration (as well as the applications server drive mapping) to the - server on the network segment on which the workstation is to be located. - </p></li></ol></div></li><li class="step" title="Step 8"><p> - When you are satisfied that the staging systems are complete, use the appropriate procedure to - remove the client from the domain. Reboot the system, and then log on as the local administrator - and clean out all temporary files stored on the system. Before shutting down, use the disk - defragmentation tool so that the file system is in optimal condition before replication. - </p></li><li class="step" title="Step 9"><p> - Boot the workstation using the Norton (Symantec) Ghosting disk (or CD-ROM) and image the - machine to a network share on the server. - </p></li><li class="step" title="Step 10"><p> - You may now replicate the image using the appropriate Norton Ghost procedure to the target - machines.

You have pretty much mastered Samba-3 for - most uses it can be put to. Up until now, you have cast Samba-3 in the leading - role, and where authentication was required, you have used one or another of - Samba's many authentication backends (from flat text files with smbpasswd - to LDAP directory integration with ldapsam). Now you can design a - solution for a new Abmas business. This business is running Windows Server - 2003 and Active Directory, and these are to stay. It's time to master - implementing Samba and Samba-supported services in a domain controlled by - the latest Windows authentication technologies. Let's get started this is - leading edge. - </p><div class="sect1" title="Introduction"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id382225"></a>Introduction</h2></div></div></div><p> - Abmas has continued its miraculous growth; indeed, nothing seems to be able - to stop its diversification into multiple (and seemingly unrelated) fields. - Its latest acquisition is Abmas Snack Foods, a big player in the snack-food - business. - </p><p> - With this acquisition comes new challenges for you and your team. Abmas Snack - Foods is a well-developed business with a huge and heterogeneous network. It - already has Windows, NetWare, and Proprietary UNIX, but as yet no Samba or Linux. - The network is mature and well-established, and there is no question of its chosen - user authentication scheme being changed for now. You need to take a wise new - approach. - </p><p> - You have decided to set the ball rolling by introducing Samba-3 into the network - gradually, taking over key services and easing the way to a full migration and, - therefore, integration into Abmas's existing business later. - </p><div class="sect2" title="Assignment Tasks"><div class="titlepage"><div><div><h3 class="title"><a name="id382248"></a>Assignment Tasks</h3></div></div></div><p> - <a class="indexterm" name="id382256"></a> - <a class="indexterm" name="id382264"></a> - You've promised the skeptical Abmas Snack Foods management team - that you can show them how Samba can ease itself and other Open Source - technologies into their existing infrastructure and deliver sound business - advantages. Cost cutting is high on their agenda (a major promise of the - acquisition). You have chosen Web proxying and caching as your proving ground. - </p><p> - <a class="indexterm" name="id382279"></a> - <a class="indexterm" name="id382286"></a> - Abmas Snack Foods has several thousand users housed at its head office - and multiple regional offices, plants, and warehouses. A high proportion of - the business's work is done online, so Internet access for most of these - users is essential. All Internet access, including for all regional offices, - is funneled through the head office and is the job of the (now your) networking - team. The bandwidth requirements were horrific (comparable to a small ISP), and - the team soon discovered proxying and caching. In fact, they became one of - the earliest commercial users of Microsoft ISA. - </p><p> - <a class="indexterm" name="id382301"></a> - <a class="indexterm" name="id382308"></a> - <a class="indexterm" name="id382315"></a> - The team is not happy with ISA. Because it never lived up to its marketing promises, - it underperformed and had reliability problems. You have pounced on the opportunity - to show what Open Source can do. The one thing they do like, however, is ISA's - integration with Active Directory. They like that their users, once logged on, - are automatically authenticated against the proxy. If your alternative to ISA - can operate completely seamlessly in their Active Directory domain, it will be - approved. - </p><p> - This is a hands-on exercise. You build software applications so - that you obtain the functionality Abmas needs. - </p></div></div><div class="sect1" title="Dissection and Discussion"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id382338"></a>Dissection and Discussion</h2></div></div></div><p> - The key requirements in this business example are straightforward.

Squid hands off - the authentication request to the Samba-3 authentication helper application - called <code class="literal">ntlm_auth</code>. This helper is a hook into winbind, the - Samba-3 NTLM authentication daemon. Winbind enables UNIX services to authenticate - against Microsoft Windows domains, including Active Directory domains. As Active - Directory authentication is a modified Kerberos authentication, winbind is assisted - in this by local Kerberos 5 libraries configured to check passwords with the Active - Directory server. Once the token has been checked, a browsing session is established. - This process is entirely transparent and seamless to the user. - </p><p> - Enabling this consists of: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - Preparing the necessary environment using preconfigured packages - </p></li><li class="listitem"><p> - Setting up raw Kerberos authentication against the Active Directory domain - </p></li><li class="listitem"><p> - Configuring, compiling, and then installing the supporting Samba-3 components - </p></li><li class="listitem"><p> - Tying it all together - </p></li></ul></div></div><div class="sect2" title="Political Issues"><div class="titlepage"><div><div><h3 class="title"><a name="id382513"></a>Political Issues</h3></div></div></div><p> - You are a stranger in a strange land, and all eyes are upon you.

All ADS domains automatically create SRV records in the - DNS zone <code class="constant">Kerberos.REALM.NAME</code> for each KDC in the realm. Since both - MIT and Heimdal, KRB5 libraries default to checking for these records, so they - automatically find the KDCs.

Kerberos is case sensitive. Your realm must - be in UPPERCASE, or you will get an error: <span class="quote">“<span class="quote">Cannot find KDC for requested realm while getting - initial credentials</span>”</span>. Kerberos is picky about time synchronization. The time - according to your participating servers must be within 5 minutes or you get an error: - <span class="quote">“<span class="quote">kinit(v5): Clock skew too great while getting initial credentials</span>”</span>. - Clock skew limits are, in fact, configurable in the Kerberos protocols (the default is - 5 minutes). A better solution is to implement NTP throughout your server network. - Kerberos needs to be able to do a reverse DNS lookup on the IP address of your KDC. - Also, the name that this reverse lookup maps to must either be the NetBIOS name of - the KDC (i.e., the hostname with no domain attached) or the - NetBIOS name followed by the realm. If all else fails, you can add a - <code class="filename">/etc/hosts</code> entry mapping the IP address of your KDC to its - NetBIOS name. If Kerberos cannot do this reverse lookup, you will get a local error - when you try to join the realm. - </p></li><li class="step" title="Step 3"><p> - <a class="indexterm" name="id383045"></a> - You are now ready to test your installation by issuing the command: -</p><pre class="screen"> -<code class="prompt">root# </code> kinit [USERNAME@REALM] -</pre><p> - You are asked for your password, which you should enter.

Likewise, the simple steps that can be taken to improve the - reliability and availability of a Samba network are often drowned out by the volume - of discussions about grandiose Samba clustering designs. This is not intended to - suggest that clustering is not important, because clearly it is. This chapter does not devote - itself to discussion of clustering because each clustering methodology uses its own - custom tools and methods. Only passing comments are offered concerning these methods. - </p><p> - <a class="indexterm" name="id384837"></a> - <a class="indexterm" name="id384844"></a> - <a class="indexterm" name="id384851"></a> -<a class="ulink" href="http://www.google.com/search?hl=en&lr=&ie=ISO-8859-1&q=samba+cluster&btnG=Google+Search" target="_top">A search</a> - for <span class="quote">“<span class="quote">samba cluster</span>”</span> produced 71,600 hits.

The term <span class="emphasis"><em>broken behavior</em></span> - means that the function of a particular Samba component appears to work sometimes, but not at - others. The resulting intermittent operation is clearly unacceptable.

Moreover, the entry in the <code class="filename">/etc/hosts</code> - on the Linux server points to IP address <code class="constant">127.0.0.1</code>. This means that - when the Windows client obtains the IP address of the Samba server called <code class="constant">LOCALHOST</code>, - it obtains the IP address <code class="constant">127.0.0.1</code> and then proceeds to attempt to - set up a NetBIOS over TCP/IP connection to it.

The <code class="filename">smb.conf</code> file is re-read by every <code class="literal">smbd</code> - process every time the file timestamp changes (or, on systems where this does not work, every 20 seconds or so). - </p><p> - As the size of the <code class="filename">smb.conf</code> file grows, the risk of introducing parsing errors also increases. - It is recommended to keep a fully documented <code class="filename">smb.conf</code> file on hand, and then to operate Samba only - with an optimized file. - </p><p><a class="indexterm" name="id385888"></a> - The preferred way to maintain a documented file is to call it something like <code class="filename">smb.conf.master</code>. - You can generate the optimized file by executing: -</p><pre class="screen"> -<code class="prompt">root# </code> testparm -s smb.conf.master > smb.conf -</pre><p> - You should carefully observe all warnings issued.

The <em class="parameter"><code>socket options</code></em> parameter was often necessary - when Samba was used with the Linux 2.2.x kernels.

Do not use this at all. There is no good reason - to use this with any modern Windows client. The <em class="parameter"><code>strict sync</code></em> is often - used with the <em class="parameter"><code>sync always</code></em> parameter. This, too, can severely - degrade network performance, so do not set it; if you must, do so with caution. - </p><p> - <a class="indexterm" name="id386064"></a> - <a class="indexterm" name="id386071"></a> - <a class="indexterm" name="id386078"></a> - <a class="indexterm" name="id386085"></a> - Finally, many network administrators deliberately disable opportunistic locking support. While this - does not degrade Samba performance, it significantly degrades Windows client performance because - this disables local file caching on Windows clients and forces every file read and written to - invoke a network read or write call. If for any reason you must disable oplocks (opportunistic locking) - support, do so only on the share on which it is required. That way, all other shares can provide - oplock support for operations that are tolerant of it.

Such - applications typically generate many small files (less than 100 KB). At the best of times, under UNIX, - listing of the files in a directory that contains many files is slow. By default, Windows NT, 200x, - and XP Pro cause network file system directory lookups on a Samba server to be performed for both - the case preserving file name as well as for the mangled (8.3) file name. This incurs a huge overhead - on the Samba server that may slow down the system dramatically. - </p><p> - In an extreme case, the performance impact was dramatic. File transfer from the Samba server to a Windows - XP Professional workstation over 1 Gigabit Ethernet for 250-500 KB files was measured at approximately - 30 MB/sec. But when tranferring a directory containing 120,000 files, all from 50KB to 60KB in size, the - transfer rate to the same workstation was measured at approximately 1.5 KB/sec. The net transfer was - on the order of a factor of 20-fold slower. - </p><p> - The symptoms that will be observed on the Samba server when a large directory is accessed will be that - aggregate I/O (typically blocks read) will be relatively low, yet the wait I/O times will be incredibly - long while at the same time the read queue is large. Close observation will show that the hard drive - that the file system is on will be thrashing wildly. - </p><p> - Samba-3.0.12 and later, includes new code that radically improves Samba perfomance. The secret to this is - really in the <a class="link" href="smb.conf.5.html#CASESENSITIVE" target="_top">case sensitive = True</a> line. This tells smbd never to scan - for case-insensitive versions of names. So if an application asks for a file called <code class="filename">FOO</code>, - and it can not be found by a simple stat call, then smbd will return "file not found" immediately without - scanning the containing directory for a version of a different case. - </p><p> - Canonicalize all the files in the directory to have one case, upper or lower - either will do. Then set up - a new custom share for the application as follows: - </p><pre class="screen"> - [bigshare] - path = /data/xrayfiles/neurosurgeons/ - read only = no - case sensitive = True - default case = upper - preserve case = no - short preserve case = no - </pre><p> - </p><p> - All files and directories under the <em class="parameter"><code>path</code></em> directory must be in the same case - as specified in the <code class="filename">smb.conf</code> stanza. This means that smbd will not be able to find lower case - filenames with these settings. Note, this is done on a per-share basis. - </p></div></div><div class="sect1" title="Key Points Learned"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id386548"></a>Key Points Learned</h2></div></div></div><p> - This chapter has touched in broad sweeps on a number of simple steps that can be taken - to ensure that your Samba network is resilient, scalable, and reliable, and that it - performs well. - </p><p> - Always keep in mind that someone is responsible to maintain and manage your design. - In the long term, that may not be you.

By contrast, the - <acronym class="acronym">GNU</acronym> General Public License is intended to guarantee your - freedom to share and change all versions of a program—to make sure it - remains free software for all its users. We, the Free Software Foundation, - use the <acronym class="acronym">GNU</acronym> General Public License for most of our - software; it applies also to any other work released this way by its - authors. You can apply it to your programs, too. - </p><p> - When we speak of free software, we are referring to freedom, not price. Our - General Public Licenses are designed to make sure that you have the freedom - to distribute copies of free software (and charge for them if you wish), - that you receive source code or can get it if you want it, that you can - change the software or use pieces of it in new free programs, and that you - know you can do these things. - </p><p> - To protect your rights, we need to prevent others from denying you these - rights or asking you to surrender the rights. Therefore, you have certain - responsibilities if you distribute copies of the software, or if you modify - it: responsibilities to respect the freedom of others. - </p><p> - For example, if you distribute copies of such a program, whether gratis or - for a fee, you must pass on to the recipients the same freedoms that you - received. You must make sure that they, too, receive or can get the source - code. And you must show them these terms so they know their rights. - </p><p> - Developers that use the <acronym class="acronym">GNU</acronym> <acronym class="acronym">GPL</acronym> - protect your rights with two steps: (1) assert copyright on the software, - and (2) offer you this License giving you legal permission to copy, - distribute and/or modify it. - </p><p> - For the developers’ and authors’ protection, the - <acronym class="acronym">GPL</acronym> clearly explains that there is no warranty for this - free software. For both users’ and authors’ sake, the - <acronym class="acronym">GPL</acronym> requires that modified versions be marked as changed, - so that their problems will not be attributed erroneously to authors of - previous versions. - </p><p> - Some devices are designed to deny users access to install or run modified - versions of the software inside them, although the manufacturer can do so. - This is fundamentally incompatible with the aim of protecting users’ - freedom to change the software. The systematic pattern of such abuse occurs - in the area of products for individuals to use, which is precisely where it - is most unacceptable. Therefore, we have designed this version of the - <acronym class="acronym">GPL</acronym> to prohibit the practice for those products. If such - problems arise substantially in other domains, we stand ready to extend this - provision to those domains in future versions of the <acronym class="acronym">GPL</acronym>, - as needed to protect the freedom of users. - </p><p> - Finally, every program is threatened constantly by software patents. States - should not allow patents to restrict development and use of software on - general-purpose computers, but in those that do, we wish to avoid the - special danger that patents applied to a free program could make it - effectively proprietary. To prevent this, the <acronym class="acronym">GPL</acronym> - assures that patents cannot be used to render the program non-free. - </p><p> - The precise terms and conditions for copying, distribution and modification - follow. - </p><h2><a name="id393937"></a> - TERMS AND CONDITIONS - </h2><h2><a name="id393940"></a> - 0. Definitions. - </h2><p> - “This License” refers to version 3 of the <acronym class="acronym">GNU</acronym> - General Public License. - </p><p> - “Copyright” also means copyright-like laws that apply to other - kinds of works, such as semiconductor masks. - </p><p> - “The Program” refers to any copyrightable work licensed under - this License. Each licensee is addressed as “you”. - “Licensees” and “recipients” may be individuals or - organizations. - </p><p> - To “modify” a work means to copy from or adapt all or part of - the work in a fashion requiring copyright permission, other than the making - of an exact copy. The resulting work is called a “modified - version” of the earlier work or a work “based on” the - earlier work. - </p><p> - A “covered work” means either the unmodified Program or a work - based on the Program. - </p><p> - To “propagate” a work means to do anything with it that, without - permission, would make you directly or secondarily liable for infringement - under applicable copyright law, except executing it on a computer or - modifying a private copy. Propagation includes copying, distribution (with - or without modification), making available to the public, and in some - countries other activities as well. - </p><p> - To “convey” a work means any kind of propagation that enables - other parties to make or receive copies. Mere interaction with a user - through a computer network, with no transfer of a copy, is not conveying. - </p><p> - An interactive user interface displays “Appropriate Legal - Notices” to the extent that it includes a convenient and prominently - visible feature that (1) displays an appropriate copyright notice, and (2) - tells the user that there is no warranty for the work (except to the extent - that warranties are provided), that licensees may convey the work under this - License, and how to view a copy of this License. If the interface presents - a list of user commands or options, such as a menu, a prominent item in the - list meets this criterion. - </p><h2><a name="id394004"></a> - 1. Source Code. - </h2><p> - The “source code” for a work means the preferred form of the - work for making modifications to it. “Object code” means any - non-source form of a work. - </p><p> - A “Standard Interface” means an interface that either is an - official standard defined by a recognized standards body, or, in the case of - interfaces specified for a particular programming language, one that is - widely used among developers working in that language. - </p><p> - The “System Libraries” of an executable work include anything, - other than the work as a whole, that (a) is included in the normal form of - packaging a Major Component, but which is not part of that Major Component, - and (b) serves only to enable use of the work with that Major Component, or - to implement a Standard Interface for which an implementation is available - to the public in source code form. A “Major Component”, in this - context, means a major essential component (kernel, window system, and so - on) of the specific operating system (if any) on which the executable work - runs, or a compiler used to produce the work, or an object code interpreter - used to run it. - </p><p> - The “Corresponding Source” for a work in object code form means - all the source code needed to generate, install, and (for an executable - work) run the object code and to modify the work, including scripts to - control those activities. However, it does not include the work’s - System Libraries, or general-purpose tools or generally available free - programs which are used unmodified in performing those activities but which - are not part of the work. For example, Corresponding Source includes - interface definition files associated with source files for the work, and - the source code for shared libraries and dynamically linked subprograms that - the work is specifically designed to require, such as by intimate data - communication or control flow between those subprograms and other parts of - the work. - </p><p> - The Corresponding Source need not include anything that users can regenerate - automatically from other parts of the Corresponding Source. - </p><p> - The Corresponding Source for a work in source code form is that same work. - </p><h2><a name="id394066"></a> - 2. Basic Permissions. - </h2><p> - All rights granted under this License are granted for the term of copyright - on the Program, and are irrevocable provided the stated conditions are met. - This License explicitly affirms your unlimited permission to run the - unmodified Program. The output from running a covered work is covered by - this License only if the output, given its content, constitutes a covered - work. This License acknowledges your rights of fair use or other - equivalent, as provided by copyright law. - </p><p> - You may make, run and propagate covered works that you do not convey, - without conditions so long as your license otherwise remains in force. You - may convey covered works to others for the sole purpose of having them make - modifications exclusively for you, or provide you with facilities for - running those works, provided that you comply with the terms of this License - in conveying all material for which you do not control copyright. Those - thus making or running the covered works for you must do so exclusively on - your behalf, under your direction and control, on terms that prohibit them - from making any copies of your copyrighted material outside their - relationship with you. - </p><p> - Conveying under any other circumstances is permitted solely under the - conditions stated below. Sublicensing is not allowed; section 10 makes it - unnecessary. - </p><h2><a name="id394094"></a> - 3. Protecting Users’ Legal Rights From Anti-Circumvention Law. - </h2><p> - No covered work shall be deemed part of an effective technological measure - under any applicable law fulfilling obligations under article 11 of the WIPO - copyright treaty adopted on 20 December 1996, or similar laws prohibiting or - restricting circumvention of such measures. - </p><p> - When you convey a covered work, you waive any legal power to forbid - circumvention of technological measures to the extent such circumvention is - effected by exercising rights under this License with respect to the covered - work, and you disclaim any intention to limit operation or modification of - the work as a means of enforcing, against the work’s users, your or - third parties’ legal rights to forbid circumvention of technological - measures. - </p><h2><a name="id394116"></a> - 4. Conveying Verbatim Copies. - </h2><p> - You may convey verbatim copies of the Program’s source code as you - receive it, in any medium, provided that you conspicuously and appropriately - publish on each copy an appropriate copyright notice; keep intact all - notices stating that this License and any non-permissive terms added in - accord with section 7 apply to the code; keep intact all notices of the - absence of any warranty; and give all recipients a copy of this License - along with the Program. - </p><p> - You may charge any price or no price for each copy that you convey, and you - may offer support or warranty protection for a fee. - </p><h2><a name="id394135"></a> - 5. Conveying Modified Source Versions. - </h2><p> - You may convey a work based on the Program, or the modifications to produce - it from the Program, in the form of source code under the terms of section - 4, provided that you also meet all of these conditions: - </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p> - The work must carry prominent notices stating that you modified it, and - giving a relevant date. - </p></li><li class="listitem"><p> - The work must carry prominent notices stating that it is released under - this License and any conditions added under section 7. This requirement - modifies the requirement in section 4 to “keep intact all - notices”. - </p></li><li class="listitem"><p> - You must license the entire work, as a whole, under this License to - anyone who comes into possession of a copy. This License will therefore - apply, along with any applicable section 7 additional terms, to the - whole of the work, and all its parts, regardless of how they are - packaged. This License gives no permission to license the work in any - other way, but it does not invalidate such permission if you have - separately received it. - </p></li><li class="listitem"><p> - If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your work need - not make them do so. - </p></li></ol></div><p> - A compilation of a covered work with other separate and independent works, - which are not by their nature extensions of the covered work, and which are - not combined with it such as to form a larger program, in or on a volume of - a storage or distribution medium, is called an “aggregate” if - the compilation and its resulting copyright are not used to limit the access - or legal rights of the compilation’s users beyond what the individual works - permit. Inclusion of a covered work in an aggregate does not cause - this License to apply to the other parts of the aggregate. - </p><h2><a name="id394207"></a> - 6. Conveying Non-Source Forms. - </h2><p> - You may convey a covered work in object code form under the terms of - sections 4 and 5, provided that you also convey the machine-readable - Corresponding Source under the terms of this License, in one of these ways: - </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p> - Convey the object code in, or embodied in, a physical product (including - a physical distribution medium), accompanied by the Corresponding Source - fixed on a durable physical medium customarily used for software - interchange. - </p></li><li class="listitem"><p> - Convey the object code in, or embodied in, a physical product (including - a physical distribution medium), accompanied by a written offer, valid - for at least three years and valid for as long as you offer spare parts - or customer support for that product model, to give anyone who possesses - the object code either (1) a copy of the Corresponding Source for all - the software in the product that is covered by this License, on a - durable physical medium customarily used for software interchange, for a - price no more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the Corresponding Source from - a network server at no charge. - </p></li><li class="listitem"><p> - Convey individual copies of the object code with a copy of the written - offer to provide the Corresponding Source. This alternative is allowed - only occasionally and noncommercially, and only if you received the - object code with such an offer, in accord with subsection 6b. - </p></li><li class="listitem"><p> - Convey the object code by offering access from a designated place - (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to copy - the object code is a network server, the Corresponding Source may be on - a different server (operated by you or a third party) that supports - equivalent copying facilities, provided you maintain clear directions - next to the object code saying where to find the Corresponding Source. - Regardless of what server hosts the Corresponding Source, you remain - obligated to ensure that it is available for as long as needed to - satisfy these requirements. - </p></li><li class="listitem"><p> - Convey the object code using peer-to-peer transmission, provided you - inform other peers where the object code and Corresponding Source of the - work are being offered to the general public at no charge under - subsection 6d. - </p></li></ol></div><p> - A separable portion of the object code, whose source code is excluded from - the Corresponding Source as a System Library, need not be included in - conveying the object code work. - </p><p> - A “User Product” is either (1) a “consumer product”, - which means any tangible personal property which is normally used for - personal, family, or household purposes, or (2) anything designed or sold - for incorporation into a dwelling. In determining whether a product is a - consumer product, doubtful cases shall be resolved in favor of coverage. - For a particular product received by a particular user, “normally - used” refers to a typical or common use of that class of product, - regardless of the status of the particular user or of the way in which the - particular user actually uses, or expects or is expected to use, the - product. A product is a consumer product regardless of whether the product - has substantial commercial, industrial or non-consumer uses, unless such - uses represent the only significant mode of use of the product. - </p><p> - “Installation Information” for a User Product means any methods, - procedures, authorization keys, or other information required to install and - execute modified versions of a covered work in that User Product from a - modified version of its Corresponding Source. The information must suffice - to ensure that the continued functioning of the modified object code is in - no case prevented or interfered with solely because modification has been - made. - </p><p> - If you convey an object code work under this section in, or with, or - specifically for use in, a User Product, and the conveying occurs as part of - a transaction in which the right of possession and use of the User Product - is transferred to the recipient in perpetuity or for a fixed term - (regardless of how the transaction is characterized), the Corresponding - Source conveyed under this section must be accompanied by the Installation - Information. But this requirement does not apply if neither you nor any - third party retains the ability to install modified object code on the User - Product (for example, the work has been installed in - <acronym class="acronym">ROM</acronym>). - </p><p> - The requirement to provide Installation Information does not include a - requirement to continue to provide support service, warranty, or updates for - a work that has been modified or installed by the recipient, or for the User - Product in which it has been modified or installed. Access to a network may - be denied when the modification itself materially and adversely affects the - operation of the network or violates the rules and protocols for - communication across the network. - </p><p> - Corresponding Source conveyed, and Installation Information provided, in - accord with this section must be in a format that is publicly documented - (and with an implementation available to the public in source code form), - and must require no special password or key for unpacking, reading or - copying. - </p><h2><a name="id394339"></a> - 7. Additional Terms. - </h2><p> - “Additional permissions” are terms that supplement the terms of - this License by making exceptions from one or more of its conditions. - Additional permissions that are applicable to the entire Program shall be - treated as though they were included in this License, to the extent that - they are valid under applicable law. If additional permissions apply only - to part of the Program, that part may be used separately under those - permissions, but the entire Program remains governed by this License - without regard to the additional permissions. - </p><p> - When you convey a copy of a covered work, you may at your option remove any - additional permissions from that copy, or from any part of it. (Additional - permissions may be written to require their own removal in certain cases - when you modify the work.) You may place additional permissions on - material, added by you to a covered work, for which you have or can give - appropriate copyright permission. - </p><p> - Notwithstanding any other provision of this License, for material you add - to a covered work, you may (if authorized by the copyright holders of that - material) supplement the terms of this License with terms: - </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p> - Disclaiming warranty or limiting liability differently from the terms - of sections 15 and 16 of this License; or - </p></li><li class="listitem"><p> - Requiring preservation of specified reasonable legal notices or author - attributions in that material or in the Appropriate Legal Notices - displayed by works containing it; or - </p></li><li class="listitem"><p> - Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - </p></li><li class="listitem"><p> - Limiting the use for publicity purposes of names of licensors or - authors of the material; or - </p></li><li class="listitem"><p> - Declining to grant rights under trademark law for use of some trade - names, trademarks, or service marks; or - </p></li><li class="listitem"><p> - Requiring indemnification of licensors and authors of that material by - anyone who conveys the material (or modified versions of it) with - contractual assumptions of liability to the recipient, for any - liability that these contractual assumptions directly impose on those - licensors and authors. - </p></li></ol></div><p> - All other non-permissive additional terms are considered “further - restrictions” within the meaning of section 10. If the Program as - you received it, or any part of it, contains a notice stating that it is - governed by this License along with a term that is a further restriction, - you may remove that term. If a license document contains a further - restriction but permits relicensing or conveying under this License, you - may add to a covered work material governed by the terms of that license - document, provided that the further restriction does not survive such - relicensing or conveying. - </p><p> - If you add terms to a covered work in accord with this section, you must - place, in the relevant source files, a statement of the additional terms - that apply to those files, or a notice indicating where to find the - applicable terms. - </p><p> - Additional terms, permissive or non-permissive, may be stated in the form - of a separately written license, or stated as exceptions; the above - requirements apply either way. - </p><h2><a name="id394444"></a> - 8. Termination. - </h2><p> - You may not propagate or modify a covered work except as expressly provided - under this License. Any attempt otherwise to propagate or modify it is - void, and will automatically terminate your rights under this License - (including any patent licenses granted under the third paragraph of section - 11). - </p><p> - However, if you cease all violation of this License, then your license from - a particular copyright holder is reinstated (a) provisionally, unless and - until the copyright holder explicitly and finally terminates your license, - and (b) permanently, if the copyright holder fails to notify you of the - violation by some reasonable means prior to 60 days after the cessation. - </p><p> - Moreover, your license from a particular copyright holder is reinstated - permanently if the copyright holder notifies you of the violation by some - reasonable means, this is the first time you have received notice of - violation of this License (for any work) from that copyright holder, and - you cure the violation prior to 30 days after your receipt of the notice. - </p><p> - Termination of your rights under this section does not terminate the - licenses of parties who have received copies or rights from you under this - License. If your rights have been terminated and not permanently - reinstated, you do not qualify to receive new licenses for the same - material under section 10. - </p><h2><a name="id394476"></a> - 9. Acceptance Not Required for Having Copies. - </h2><p> - You are not required to accept this License in order to receive or run a - copy of the Program. Ancillary propagation of a covered work occurring - solely as a consequence of using peer-to-peer transmission to receive a - copy likewise does not require acceptance. However, nothing other than - this License grants you permission to propagate or modify any covered work. - These actions infringe copyright if you do not accept this License. - Therefore, by modifying or propagating a covered work, you indicate your - acceptance of this License to do so. - </p><h2><a name="id394495"></a> - 10. Automatic Licensing of Downstream Recipients. - </h2><p> - Each time you convey a covered work, the recipient automatically receives a - license from the original licensors, to run, modify and propagate that - work, subject to this License. You are not responsible for enforcing - compliance by third parties with this License. - </p><p> - An “entity transaction” is a transaction transferring control - of an organization, or substantially all assets of one, or subdividing an - organization, or merging organizations. If propagation of a covered work - results from an entity transaction, each party to that transaction who - receives a copy of the work also receives whatever licenses to the work the - party’s predecessor in interest had or could give under the previous - paragraph, plus a right to possession of the Corresponding Source of the - work from the predecessor in interest, if the predecessor has it or can get - it with reasonable efforts. - </p><p> - You may not impose any further restrictions on the exercise of the rights - granted or affirmed under this License. For example, you may not impose a - license fee, royalty, or other charge for exercise of rights granted under - this License, and you may not initiate litigation (including a cross-claim - or counterclaim in a lawsuit) alleging that any patent claim is infringed - by making, using, selling, offering for sale, or importing the Program or - any portion of it. - </p><h2><a name="id394529"></a> - 11. Patents. - </h2><p> - A “contributor” is a copyright holder who authorizes use under - this License of the Program or a work on which the Program is based. The - work thus licensed is called the contributor’s “contributor - version”. - </p><p> - A contributor’s “essential patent claims” are all patent - claims owned or controlled by the contributor, whether already acquired or - hereafter acquired, that would be infringed by some manner, permitted by - this License, of making, using, or selling its contributor version, but do - not include claims that would be infringed only as a consequence of further - modification of the contributor version. For purposes of this definition, - “control” includes the right to grant patent sublicenses in a - manner consistent with the requirements of this License. - </p><p> - Each contributor grants you a non-exclusive, worldwide, royalty-free patent - license under the contributor’s essential patent claims, to make, use, - sell, offer for sale, import and otherwise run, modify and propagate the - contents of its contributor version. - </p><p> - In the following three paragraphs, a “patent license” is any - express agreement or commitment, however denominated, not to enforce a - patent (such as an express permission to practice a patent or covenant not - to sue for patent infringement). To “grant” such a patent - license to a party means to make such an agreement or commitment not to - enforce a patent against the party. - </p><p> - If you convey a covered work, knowingly relying on a patent license, and the - Corresponding Source of the work is not available for anyone to copy, free - of charge and under the terms of this License, through a publicly available - network server or other readily accessible means, then you must either (1) - cause the Corresponding Source to be so available, or (2) arrange to deprive - yourself of the benefit of the patent license for this particular work, or - (3) arrange, in a manner consistent with the requirements of this License, - to extend the patent license to downstream recipients. “Knowingly - relying” means you have actual knowledge that, but for the patent - license, your conveying the covered work in a country, or your - recipient’s use of the covered work in a country, would infringe one - or more identifiable patents in that country that you have reason to believe - are valid. - </p><p> - If, pursuant to or in connection with a single transaction or arrangement, - you convey, or propagate by procuring conveyance of, a covered work, and - grant a patent license to some of the parties receiving the covered work - authorizing them to use, propagate, modify or convey a specific copy of the - covered work, then the patent license you grant is automatically extended to - all recipients of the covered work and works based on it. - </p><p> - A patent license is “discriminatory” if it does not include - within the scope of its coverage, prohibits the exercise of, or is - conditioned on the non-exercise of one or more of the rights that are - specifically granted under this License. You may not convey a covered work - if you are a party to an arrangement with a third party that is in the - business of distributing software, under which you make payment to the third - party based on the extent of your activity of conveying the work, and under - which the third party grants, to any of the parties who would receive the - covered work from you, a discriminatory patent license (a) in connection - with copies of the covered work conveyed by you (or copies made from those - copies), or (b) primarily for and in connection with specific products or - compilations that contain the covered work, unless you entered into that - arrangement, or that patent license was granted, prior to 28 March 2007. - </p><p> - Nothing in this License shall be construed as excluding or limiting any - implied license or other defenses to infringement that may otherwise be - available to you under applicable patent law. - </p><h2><a name="id394618"></a> - 12. No Surrender of Others’ Freedom. - </h2><p> - If conditions are imposed on you (whether by court order, agreement or - otherwise) that contradict the conditions of this License, they do not - excuse you from the conditions of this License. If you cannot convey a - covered work so as to satisfy simultaneously your obligations under this - License and any other pertinent obligations, then as a consequence you may - not convey it at all. For example, if you agree to terms that obligate you - to collect a royalty for further conveying from those to whom you convey the - Program, the only way you could satisfy both those terms and this License - would be to refrain entirely from conveying the Program. - </p><h2><a name="id394633"></a> - 13. Use with the <acronym class="acronym">GNU</acronym> Affero General Public License. - </h2><p> - Notwithstanding any other provision of this License, you have permission to - link or combine any covered work with a work licensed under version 3 of the - <acronym class="acronym">GNU</acronym> Affero General Public License into a single combined - work, and to convey the resulting work. The terms of this License will - continue to apply to the part which is the covered work, but the special - requirements of the <acronym class="acronym">GNU</acronym> Affero General Public License, - section 13, concerning interaction through a network will apply to the - combination as such. - </p><h2><a name="id394657"></a> - 14. Revised Versions of this License. - </h2><p> - The Free Software Foundation may publish revised and/or new versions of the - <acronym class="acronym">GNU</acronym> General Public License from time to time. Such new - versions will be similar in spirit to the present version, but may differ in - detail to address new problems or concerns. - </p><p> - Each version is given a distinguishing version number. If the Program - specifies that a certain numbered version of the <acronym class="acronym">GNU</acronym> - General Public License “or any later version” applies to it, you - have the option of following the terms and conditions either of that - numbered version or of any later version published by the Free Software - Foundation. If the Program does not specify a version number of the - <acronym class="acronym">GNU</acronym> General Public License, you may choose any version - ever published by the Free Software Foundation. - </p><p> - If the Program specifies that a proxy can decide which future versions of - the <acronym class="acronym">GNU</acronym> General Public License can be used, that - proxy’s public statement of acceptance of a version permanently - authorizes you to choose that version for the Program. - </p><p> - Later license versions may give you additional or different permissions. - However, no additional obligations are imposed on any author or copyright - holder as a result of your choosing to follow a later version. - </p><h2><a name="id394704"></a> - 15. Disclaimer of Warranty. - </h2><p> - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE - LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR - OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF - ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE - IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. - THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH - YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL - NECESSARY SERVICING, REPAIR OR CORRECTION. - </p><h2><a name="id394722"></a> - 16. Limitation of Liability. - </h2><p> - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL - ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE - PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY - GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE - OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA - OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD - PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), - EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF - SUCH DAMAGES. - </p><h2><a name="id394736"></a> - 17. Interpretation of Sections 15 and 16. - </h2><p> - If the disclaimer of warranty and limitation of liability provided above - cannot be given local legal effect according to their terms, reviewing - courts shall apply local law that most closely approximates an absolute - waiver of all civil liability in connection with the Program, unless a - warranty or assumption of liability accompanies a copy of the Program in - return for a fee. - </p><h2><a name="id394749"></a> - END OF TERMS AND CONDITIONS - </h2><h2><a name="id394752"></a> - How to Apply These Terms to Your New Programs - </h2><p> - If you develop a new program, and you want it to be of the greatest possible - use to the public, the best way to achieve this is to make it free software - which everyone can redistribute and change under these terms. - </p><p> - To do so, attach the following notices to the program. It is safest to - attach them to the start of each source file to most effectively state the - exclusion of warranty; and each file should have at least the - “copyright” line and a pointer to where the full notice is - found. - </p><pre class="screen"> -<em class="replaceable"><code>one line to give the program’s name and a brief idea of what it does.</code></em> -Copyright (C) <em class="replaceable"><code>year</code></em> <em class="replaceable"><code>name of author</code></em> - -This program is free software: you can redistribute it and/or modify -it under the terms of the <acronym class="acronym">GNU</acronym> General Public License as published by -the Free Software Foundation, either version 3 of the License, or -(at your option) any later version. - -This program is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

For example, LAM does not permit the creation of Windows user and group - accounts that contain spaces even though the underlying UNIX/Linux - operating system may exhibit no problems with them. Given the propensity for using upper-case - characters and spaces (particularly in the default Windows account names) this may cause - some annoyance. For the rest, LAM is a very useful administrative tool. - </p><p> - The next major release, LAM 0.5, will have fewer restrictions and support the latest Samba features - (e.g., logon hours). The new plugin-based architecture also allows management of much more different - account types like plain UNIX accounts. The upload can now handle groups and hosts, too.

It offers a simple and ergonomic - interface for managing a Samba domain controler. The goal is to give Linux administrators who - need to manage production Samba servers an effective, intuitive and consistent management - experience. An IMC screenshot of the user management tool is shown in <a class="link" href="appendix.html#imcidealx" title="Figure 15.12.

If the file is executable and the SUID bit is set, it executes with the privilege - of (with the UID of) the owner of the file. For example, if you are logged onto a system as - a normal user (let's say as the user <code class="constant">bobj</code>), and you execute a file that is owned - by the user <code class="constant">root</code> (uid = 0), and the file has the SUID bit set, then the file is - executed as if you had logged in as the user <code class="constant">root</code> and then executed the file. - The SUID bit effectively gives you (as <code class="constant">bobj</code>) administrative privilege for the - use of that executable file. - </p><p> - The setting of the SGID bit does precisely the same as the effect of the SUID bit, except that it - applies the privilege to the UNIX group setting. In other words, the file executes with the force - of capability of the group. - </p><p> - When the SUID/SGID permissions are set on a directory, all files that are created within that directory - are automatically given the ownership of the SUID user and the SGID group, as per the ownership - of the directory in which the file is created. This means that the system level <code class="literal">create()</code> - function executes with the SUID user and/or SGID group of the directory in which the file is - created. - </p><p> - If you want to obtain the SUID behavior, simply execute the following command: -</p><pre class="screen"> -<code class="prompt">root# </code> chmod u+s file-or-directory -</pre><p> - To set the SGID properties on a file or a directory, execute this command: -</p><pre class="screen"> -<code class="prompt">root# </code> chmod g+s file-or-directory -</pre><p> - And to set both SUID and SGID properties, execute the following: -</p><pre class="screen"> -<code class="prompt">root# </code> chmod ug+s file-or-directory -</pre><p> - </p><p> - Let's consider the example of a directory <code class="filename">/data/accounts</code>.

It should be noted that there are sites that have a single PDC for many hundreds of -concurrent network clients. Network bandwidth, network bandwidth utilization, and server load -are among the factors that determine the maximum number of Windows clients that -can be served by a single domain controller (PDC or BDC) on a network segment. It is possible -to operate with only a single PDC over a routed network. What is possible is not necessarily -<span class="emphasis"><em>best practice</em></span>. When Windows client network logons begin to fail with -the message that the domain controller cannot be found or that the user account cannot -be found (when you know it exists), that may be an indication that the domain controller is -overloaded or network bandwidth is overloaded.

This is one of the primary factors that govern the installation of - multiple domain controllers (usually called secondary or backup controllers). - As a rough rule, there should be one such backup controller for every - 30 to 150 clients. The actual limits are determined by network operational - characteristics. - </p><p> - <a class="indexterm" name="id341061"></a> - <a class="indexterm" name="id341068"></a> - <a class="indexterm" name="id341074"></a> - If the domain controller provides only network logon services - and all file and print activity is handled by domain member servers, one domain - controller per 150 clients on a single network segment may suffice. In any - case, it is highly recommended to have a minimum of one domain controller (PDC or BDC) - per network segment. It is better to have at least one BDC on the network - segment that has a PDC. If the domain controller is also used as a file and - print server, the number of clients it can service reliably is reduced, - and generally for low powered hardware should not exceed 30 machines (Windows - workstations plus domain member servers) per domain controller. Many sites are - able to operate with more clients per domain controller, the number of clients - that can be supported is limited by the CPU speed, memory and the workload on - the Samba server as well as network bandwidth utilization. - </p></dd><dt><span class="term">Slow logons and log-offs</span></dt><dd><p> - <a class="indexterm" name="id341100"></a> - Slow logons and log-offs may be caused by many factors that include: - - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - <a class="indexterm" name="id341113"></a> - <a class="indexterm" name="id341125"></a> - Excessive delays in the resolution of a NetBIOS name to its IP - address.

If you are migrating from Microsoft Active Directory, be warned that OpenLDAP does not include - GUI-based directory management tools.

OpenLDAP is an LDAP directory - tool-set. Microsoft Active Directory Server is an implementation of an LDAP server that is largely preconfigured - for a specific task orientation. It comes with a set of administrative tools that is entirely customized - for the purpose of running MS Windows applications that include file and print services, Microsoft Exchange - server, Microsoft SQL server, and more. The complexity of OpenLDAP is highly valued by the UNIX administrator - who wants to build a custom directory solution. Microsoft provides an application called - <a class="ulink" href="http://www.microsoft.com/windowsserver2003/adam/default.mspx" target="_top"> - MS ADAM</a> that provides more generic LDAP services, yet it does not have the vanilla-like services - of OpenLDAP. - </p><p> - <a class="indexterm" name="id341906"></a> - <a class="indexterm" name="id341915"></a> - You may wish to consider outsourcing the development of your OpenLDAP directory to an expert, particularly - if you find the challenge of learning about LDAP directories, schemas, configuration, and management - tools and the creation of shell and Perl scripts a bit - challenging. OpenLDAP can be easily customized, though it includes - many ready-to-use schemas. Samba-3 provides an OpenLDAP schema file - that is required for use as a passdb backend. - </p><p> - <a class="indexterm" name="id341929"></a> - For those who are willing to brave the process of installing and configuring LDAP and Samba-3 interoperability, - there are a few nice Web-based tools that may help you to manage your users and groups more effectively. - The Web-based tools you might like to consider include the - <a class="ulink" href="http://lam.sourceforge.net/" target="_top">LDAP Account Manager</a> (LAM) and the Webmin-based - <a class="ulink" href="http://www.webmin.com" target="_top">Webmin</a> Idealx - <a class="ulink" href="http://webmin.idealx.org/index.en.html" target="_top">CGI tools</a>. - </p><p> - Some additional LDAP tools should be mentioned.

First, the absence of a domain controller on the local network is the - main cause of the errors that result in blue screen crashes. Second, Mary has a large profile that must - be loaded over the WAN connection. The addition of BDCs on each network segment significantly - improves overall network performance for most users, but it is not enough.

So far in this book, you have experienced only what is generally - known as <span class="quote">“<span class="quote">dumb</span>”</span> printing. Dumb printing is the arrangement by which all drivers - are manually installed on each client and the printing subsystems perform no filtering - or intelligent processing. Dumb printing is easily understood. It usually works without - many problems, but it has its limitations also.

What this provides is - essentially the ability to print to any printer. If the local client does not yet have a - driver installed, the driver is automatically downloaded from the Samba server and - installed on the client. Drag-and-drop printing is neat; it means the user never needs - to fuss with driver installation, and that is a <span class="trademark">Good Thing,</span>™ - isn't it? - </p><p> - There is a further layer of print job processing that is known as <code class="literal">intelligent</code> - printing that automatically senses the file format of data submitted for printing and - then invokes a suitable print filter to convert the incoming data stream into a format - suited to the printer to which the job is dispatched. - </p><p> - <a class="indexterm" name="id343057"></a> - <a class="indexterm" name="id343064"></a> - <a class="indexterm" name="id343071"></a> - The CUPS printing subsystem is capable of intelligent printing. It has the capacity to - detect the data format and apply a print filter. This means that it is feasible to install - on all Windows clients a single printer driver for use with all printers that are routed - through CUPS. The most sensible driver to use is one for a PostScript printer. Fortunately, - <a class="ulink" href="http://www.easysw.com" target="_top">Easy Software Products</a>, the authors of CUPS, have - released a PostScript printing driver for Windows. It can be installed into the Samba - printing backend so that it automatically downloads to the client when needed. - </p><p> - This means that so long as there is a CUPS driver for the printer, all printing from Windows - software can use PostScript, no matter what the actual printer language for the physical - device is.

It does not - hurt to have UNIX user and group accounts in both the system files as well as in the LDAP - database. From a UNIX system perspective, the NSS resolver checks system files before - referring to LDAP. If the UNIX system can resolve (find) an account in the system file, it - does not need to ask LDAP. - </p><p> - Addition of an account to the LDAP backend can be done in two ways: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - <a class="indexterm" name="id346574"></a> - <a class="indexterm" name="id346580"></a> - <a class="indexterm" name="id346587"></a> - <a class="indexterm" name="id346594"></a> - <a class="indexterm" name="id346601"></a> - <a class="indexterm" name="id346608"></a> - If you always have a user account in the <code class="filename">/etc/passwd</code> on every - server or in a NIS(+) backend, it is not necessary to add POSIX accounts for them in - LDAP. In this case, you can add Windows domain user accounts using the - <code class="literal">pdbedit</code> utility. Use of this tool from the command line adds the - SambaSamAccount entry for the user, but does not add the PosixAccount entry for the user. - </p><p> - This is the least desirable method because when LDAP is used as the passwd backend Samba - expects the POSIX account to be in LDAP also. It is possible to use the PADL account - migration tool to migrate all system accounts from either the <code class="filename">/etc/passwd</code> - files, or from NIS, to LDAP. - </p></li><li class="listitem"><p> - If you decide that it is probably a good idea to add both the PosixAccount attributes - as well as the SambaSamAccount attributes for each user, then a suitable script is needed. - In the example system you are installing in this exercise, you are making use of the - Idealx smbldap-tools scripts.

You use the <code class="literal">smbldap-populate</code> to - seed the LDAP database. You then manually add the accounts shown in <a class="link" href="happy.html#sbehap-bigacct" title="Table 5.3.

In the Samba-3 <code class="filename">smb.conf</code> files, specific use is made - of the People container, not the Computers container, for domain member accounts. This is not a - mistake; it is a deliberate action that is necessitated by the fact that the resolution of - a machine (computer) account to a UID is done via NSS. The only way this can be handled is - using the NSS (<code class="filename">/etc/nsswitch.conf</code>) entry for <code class="constant">passwd</code>, - which is resolved using the <code class="filename">nss_ldap</code> library. The configuration file for - the <code class="filename">nss_ldap</code> library is the file <code class="filename">/etc/ldap.conf</code> that - provides only one possible LDAP search command that is specified by the entry called - <code class="constant">nss_base_passwd</code>. This means that the search path must take into account - the directory structure so that the LDAP search will commence at a level that is above - both the Computers container and the Users (or People) container. If this is done, it is - necessary to use a search that will descend the directory tree so that the machine account - can be found. Alternatively, by placing all machine accounts in the People container, we - are able to sidestep this limitation. This is the simpler solution that has been adopted - in this chapter. - </p></div><div class="table"><a name="sbehap-bigacct"></a><p class="title"><b>Table 5.3.

This means that you can manage software maintenance from a central - perspective and that only minimal application stubware needs to be installed onto the desktop - systems. You should proceed with software installation and default configuration as far as is humanly - possible and so long as it makes sense to do so. Make certain to thoroughly test and validate every aspect - of software operations and configuration. - </p><p> - When you believe that the overall configuration is complete, be sure to create a shared group profile - and migrate that to the Samba server for later reuse when creating custom mandatory profiles, just in - case a user may have specific needs you had not anticipated. - </p></div><div class="sect2" title="Roll-out Image Creation"><div class="titlepage"><div><div><h3 class="title"><a name="id352391"></a>Roll-out Image Creation</h3></div></div></div><p> - The final steps before preparing the distribution Norton Ghost image file you might follow are: - </p><div class="blockquote"><blockquote class="blockquote"><p> - Unjoin the domain Each workstation requires a unique name and must be independently - joined into domain membership. - </p></blockquote></div><div class="blockquote"><blockquote class="blockquote"><p> - Defragment the hard disk While not obvious to the uninitiated, defragmentation results - in better performance and often significantly reduces the size of the compressed disk image.

Is it a sad fact that the example presented deliberately - avoided any consideration of security. Security does not just happen; you must design it into your total - network. Security begins with a systems design and implementation that anticipates hostile behavior from - users both inside and outside the organization. Hostile and malicious intruders do not respect barriers; - they accept them as challenges. For that reason, if not simply from a desire to establish safe networking - practices, you must not deploy the design presented in this book in an environment where there is risk - of compromise. - </p><p> - <a class="indexterm" name="id352437"></a> - <a class="indexterm" name="id352445"></a> - As a minimum, the LDAP server must be protected by way of Access Control Lists (ACLs), and it must be - configured to use secure protocols for all communications over the network. Of course, secure networking - does not result just from systems design and implementation but involves constant user education - training and, above all, disciplined attention to detail and constant searching for signs of unfriendly - or alien activities.

This is a book about Samba, not about OpenLDAP and secure - communication protocols for subjects other than Samba. Earlier on, you note, - that the dynamic DNS and DHCP solutions also used no protective secure communications - protocols. The reason for this is simple: There are so many ways of implementing - secure protocols that this book would have been even larger and more complex. - </p><p> - The solutions presented here all work (at least they did for me). Network administrators - have the interest and the need to be better trained and instructed in secure networking - practices and ought to implement safe systems. I made the decision, right or wrong, - to keep this material as simple as possible. The intent of this book is to demonstrate - a working solution and not to discuss too many peripheral issues. - </p><p> - This book makes little mention of backup techniques. Does that mean that I am recommending - that you should implement a network without provision for data recovery and for disaster - management?

The differences are marginal. Surely you know - your Linux platform, and you do have access to administration manuals for it. This - book is not a Linux tutorial; it is a Samba tutorial. Let's keep the focus on - the Samba part of the book; all the other bits are peripheral (but important) to - creation of a total network solution. - </p><p> - What I find interesting is the attention reviewers give to Linux installation and to - the look and feel of the desktop, but does that make for a great server? In this book, - I have paid particular attention to the details of creating a whole solution framework. - I have not tightened every nut and bolt, but I have touched on all the issues you - need to be familiar with. Over the years many people have approached me wanting to - know the details of exactly how to implement a DHCP and dynamic DNS server with Samba - and WINS. In this chapter, it is plain to see what needs to be configured to provide - transparent interoperability. Likewise for CUPS and Samba interoperation. These are - key stumbling areas for many people. - </p><p> - At every critical junction, I have provided comparative guidance for both SUSE and - Red Hat Linux. Both manufacturers have done a great job in furthering the cause - of open source software. I favor neither and respect both. I like particular - features of both products (companies also).

If you have taken the time to - practice, you likely have thought of improvements and scenarios with which you can experiment. You - are rather well plugged in to the many flexible ways Samba can be used. - </p><p><a class="indexterm" name="id377090"></a> - This is a book about Samba-3. Understandably, its intent is to present it in a positive light. - The casual observer might conclude that this book is one-eyed about Samba. It is what - would you expect? This chapter exposes some criticisms that have been raised concerning - the use of Samba. For each criticism, there are good answers and appropriate solutions. - </p><p> - Some criticism always comes from deep inside ranks that one would expect to be supportive of a particular - decision. Criticism can be expected from the outside. Let's see how the interesting dynamic of - criticism develops with respect to Abmas. - </p><p><a class="indexterm" name="id377113"></a> - This chapter provides a shameless self-promotion of Samba-3. The objections raised were not pulled - out of thin air. They were drawn from comments made by Samba users and from criticism during - discussions with Windows network administrators. The tone of the objections reflects as closely - as possible that of the original. The case presented is a straw-man example that is designed to - permit each objection to be answered as it might occur in real life. - </p><div class="sect1" title="Introduction"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id377126"></a>Introduction</h2></div></div></div><p><a class="indexterm" name="id377133"></a><a class="indexterm" name="id377141"></a><a class="indexterm" name="id377148"></a><a class="indexterm" name="id377156"></a><a class="indexterm" name="id377164"></a> - Abmas is continuing its meteoric growth with yet further acquisitions. The investment community took - note of the spectacular projection of Abmas onto the global business stage. Abmas is building an - interesting portfolio of companies that includes accounting services, financial advice, investment - portfolio management, property insurance, risk assessment, and the recent addition of a a video rental - business. The pieces do not always appear to fit together, but Mr. Meany is certainly executing an - interesting business growth and development plan. Abmas Video Rentals was recently acquired. - During the time that the acquisition was closing, the Video Rentals business upgraded its Windows - NT4-based network to Windows 2003 Server and Active Directory. - </p><p><a class="indexterm" name="id377182"></a> - You have accepted the fact that Abmas Video Rentals will use Microsoft Active Directory. - The IT team, led by Stan Soroka, is committed to Samba-3 and to maintaining a uniform technology platform. - Stan Soroka's team voiced its disapproval over the decision to permit this business to continue to - operate with a solution that is viewed by Christine and her group as <span class="quote">“<span class="quote">an island of broken - technologies.</span>”</span> This comment was made by one of Christine's staff as they were installing a new - Samba-3 server at the new business. - </p><p><a class="indexterm" name="id377201"></a><a class="indexterm" name="id377209"></a> - Abmas Video Rentals' head of IT heard of this criticism. He was offended that a junior engineer - should make such a comment. He felt that he had to prepare in case he might be criticized for his - decision to use Active Directory. He decided he would defend his decision by hiring the services - of an outside security systems consultant to report<sup>[<a name="id377221" href="#ftn.id377221" class="footnote">12</a>]</sup> on his unit's operations - and to investigate the role of Samba at his site.

File system shares are - appropriately secured. Backup and disaster recovery plans are well managed and validated regularly, and - effective off-site storage practices are considered to exceed industry norms. - </p><p><a class="indexterm" name="id377332"></a><a class="indexterm" name="id377340"></a><a class="indexterm" name="id377347"></a> - Your staff are justifiably concerned that the use of Samba may compromise their good efforts to maintain - a secure network. - </p><p><a class="indexterm" name="id377363"></a><a class="indexterm" name="id377371"></a><a class="indexterm" name="id377379"></a><a class="indexterm" name="id377387"></a> - The recently installed Linux file and application server uses a tool called <code class="literal">winbind</code> - that is indiscriminate about security. All user accounts in Active Directory can be used to access data - stored on the Linux system. We are alarmed that secure information is accessible to staff who should - not even be aware that it exists. We share the concerns of your network management staff who have gone - to great lengths to set fine-grained controls that limit information access to those who need access. - It seems incongruous to us that Samba winbind should be permitted to be used considering that it voids this fine work. - </p><p><a class="indexterm" name="id377412"></a><a class="indexterm" name="id377420"></a><a class="indexterm" name="id377428"></a> - Graham Judd [head of network administration] has locked down the security of all systems and is following - the latest Microsoft guidelines. ... null session connections have been disabled ... the internal network - is isolated from the outside world, the [product name removed] firewall is under current contract - maintenance support from [the manufacturer]. ... our attempts to penetrate security of your systems - failed to find problems common to Windows networking sites.

It is our opinion that Samba offers no better security than Microsoft - ... what worries us regarding Samba is the need to disable essential Windows security features such as - secure channel support, digital sign'n'seal on all communication traffic, and running Active Directory in - mixed mode so that Samba clients and servers can authenticate all of it. Additionally, we are concerned that - Samba is not at the full capabilities of Microsoft Windows NT4 server. Microsoft has moved well beyond that - with trusted computing initiatives that the Samba developers do not participate in. - </p><p><a class="indexterm" name="id377489"></a><a class="indexterm" name="id377496"></a><a class="indexterm" name="id377504"></a><a class="indexterm" name="id377512"></a><a class="indexterm" name="id377520"></a><a class="indexterm" name="id377528"></a><a class="indexterm" name="id377536"></a> - One wonders about the integrity of an open source program that is developed by a team of hackers - who cannot be held accountable for the flaws in their code. The sheer number of updates and bug - fixes they have released should ring alarm bells in any business. - </p><p><a class="indexterm" name="id377549"></a><a class="indexterm" name="id377557"></a><a class="indexterm" name="id377565"></a> - Another factor that should be considered is that buying Microsoft products and services helps to - provide employment in the IT industry.

I propose that dissenters will still remain - responsible to meet the budgeted contribution to IT operations as a whole. I believe we should not coerce - use of any centrally proposed standards, but make all noncompliance the financial responsibility of the - out-of-step division.

No one is pounding your door to make you use Samba. That is a choice that you are free to - make or reject. It is likely that your decision to use Samba can greatly benefit your company. - The Samba Team obviously believes that the Samba software is a worthy choice. - If you hire a consultant to assist with the installation and/or deployment of Samba, or if you hire - someone to help manage your Samba installation, you can create income and employment. Alternately, - money saved by not spending in the IT area can be spent elsewhere in the business. All money saved - or spent creates employment. - </p><p><a class="indexterm" name="id377794"></a><a class="indexterm" name="id377802"></a><a class="indexterm" name="id377809"></a><a class="indexterm" name="id377817"></a><a class="indexterm" name="id377825"></a> - In the long term, the use of Samba must be economically sustainable. In some situations, Samba is adopted - purely to provide file and print service interoperability on platforms that otherwise cannot provide - access to data and to printers for Microsoft Windows clients. Samba is used by some businesses to - effect a reduction in the cost of providing IT services. Obviously, it is also used by some as an - alternative to the use of a Microsoft file and print serving platforms with no consideration of costs. - </p><p><a class="indexterm" name="id377841"></a><a class="indexterm" name="id377848"></a><a class="indexterm" name="id377856"></a><a class="indexterm" name="id377864"></a> - It would be foolish to adopt a technology that might put any data or users at risk. Security affects - everyone. The Samba-Team is fully cognizant of the responsibility they have to their users. - The Samba documentation clearly reveals that full responsibility is accepted to fix anything - that is broken. - </p><p><a class="indexterm" name="id377878"></a><a class="indexterm" name="id377886"></a><a class="indexterm" name="id377894"></a><a class="indexterm" name="id377902"></a><a class="indexterm" name="id377913"></a><a class="indexterm" name="id377921"></a><a class="indexterm" name="id377929"></a><a class="indexterm" name="id377937"></a><a class="indexterm" name="id377945"></a><a class="indexterm" name="id377952"></a><a class="indexterm" name="id377960"></a> - There is a mistaken perception in the IT industry that commercial software providers are fully - accountable for the defects in products. Open Source software comes with no warranty, so it is - often assumed that its use confers a higher degree of risk. Everyone should read commercial software - End User License Agreements (EULAs). You should determine what real warranty is offered and the - extent of liability that is accepted. Doing so soon dispels the popular notion that - commercial software vendors are willingly accountable for product defects. In many cases, the - commercial vendor accepts liability only to reimburse the price paid for the software. - </p><p><a class="indexterm" name="id377977"></a><a class="indexterm" name="id377985"></a><a class="indexterm" name="id377993"></a><a class="indexterm" name="id378001"></a><a class="indexterm" name="id378009"></a><a class="indexterm" name="id378016"></a> - The real issues that a consumer (like you) needs answered are What is the way of escape from technical - problems, and how long will it take? The average problem turnaround time in the Open Source community is - approximately 48 hours. What does the EULA offer? What is the track record in the commercial software - industry?

The Kerberos protocol uses - strong cryptography so that a client can prove its identity to a server (and vice versa) across an - insecure network connection.

That means that there is a third party (the kerberos - server) that is trusted by all the entities on the network (users and services, usually called - principals). All principals share a secret password (or key) with the kerberos server and this - enables principals to verify that the messages from the kerberos server are authentic.

In this case, you want to permit all members of the group <code class="constant">Employees</code> - except the user <code class="constant">patrickj</code> to access the <code class="constant">Apps</code> share. This can be - easily achieved by setting a share-level ACL permitting only <code class="constant">Employees</code> to access the share, - and then in the share definition controls excluding just <code class="constant">patrickj</code>. Here is how that might - be done: -</p><pre class="screen"> -[Apps] - comment = Application Share - path = /data/apps - read only = Yes - invalid users = patrickj -</pre><p> - <a class="indexterm" name="id380224"></a> - Let us assume that you want to permit the user <code class="constant">gbshaw</code> to manage any file in the - UNIX/Linux file system directory <code class="filename">/data/apps</code>, but you do not want to grant any write - permissions beyond that directory tree.

For example, if for the same share we now - want to provide the user <code class="constant">peters</code> with the ability to write to one directory to - which he has write privilege in the UNIX file system, you can specifically permit that with the - following settings: -</p><pre class="screen"> -[Apps] - comment = Application Share - path = /data/apps - read only = Yes - invalid users = patrickj - admin users = gbshaw - write list = peters -</pre><p> - <a class="indexterm" name="id380303"></a> - This is a particularly complex example at this point, but it begins to demonstrate the possibilities. - You should refer to the online manual page for the <code class="filename">smb.conf</code> file for more information regarding - the checkpoint controls that Samba implements. - </p></div><div class="sect3" title="Override Controls"><div class="titlepage"><div><div><h4 class="title"><a name="id380322"></a>Override Controls</h4></div></div></div><p><a class="indexterm" name="id380328"></a> - Override controls implemented by Samba permit actions like the adoption of a different identity - during file system operations, the forced overwriting of normal file and directory permissions, - and so on. You should refer to the online manual page for the <code class="filename">smb.conf</code> file for more information regarding - the override controls that Samba implements. - </p><p> - In the following example, you want to create a Windows networking share that any user can access. - However, you want all read and write operations to be performed as if the user <code class="constant">billc</code> - and member of the group <code class="constant">Mentors</code> read/write the files.

Well, it is almost that simple. The downside of this method is that - users are logged onto the Windows client as themselves, and then immediately before accessing the - file, Samba makes system calls to change the effective user and group to the forced settings - specified, completes the file transaction, and then reverts to the actually logged-on identity. - This imposes significant overhead on Samba. The alternative way to effectively achieve the same result - (but with lower system CPU overheads) is described next. - </p><p><a class="indexterm" name="id380389"></a><a class="indexterm" name="id380397"></a><a class="indexterm" name="id380405"></a><a class="indexterm" name="id380416"></a><a class="indexterm" name="id380424"></a> - The use of the <em class="parameter"><code>force user</code></em> or the <em class="parameter"><code>force group</code></em> may - also have a severe impact on system (particularly on Windows client) performance. If opportunistic - locking is enabled on the share (the default), it causes an <code class="constant">oplock break</code> to be - sent to the client even if the client has not opened the file. On networks that have high traffic - density, or on links that are routed to a remote network segment, <code class="constant">oplock breaks</code> - can be lost. This results in possible retransmission of the request, or the client may time-out while - waiting for the file system transaction (read or write) to complete. The result can be a profound - apparent performance degradation as the client continually attempts to reconnect to overcome the - effect of the lost <code class="constant">oplock break</code>, or time-out. - </p></div></div><div class="sect2" title="Share Point Directory and File Permissions"><div class="titlepage"><div><div><h3 class="title"><a name="id380465"></a>Share Point Directory and File Permissions</h3></div></div></div><p><a class="indexterm" name="id380472"></a><a class="indexterm" name="id380480"></a><a class="indexterm" name="id380488"></a><a class="indexterm" name="id380496"></a> - Samba has been designed and implemented so that it respects as far as is feasible the security and - user privilege controls that are built into the UNIX/Linux operating system. Samba does nothing - with respect to file system access that violates file system permission settings, unless it is - explicitly instructed to do otherwise through share definition controls. Given that Samba obeys - UNIX file system controls, this chapter does not document simple information that can be obtained - from a basic UNIX training guide. Instead, one common example of a typical problem is used - to demonstrate the most effective solution referred to in the immediately preceding paragraph. - </p><p><a class="indexterm" name="id380512"></a><a class="indexterm" name="id380520"></a><a class="indexterm" name="id380528"></a> - One of the common issues that repeatedly pops up on the Samba mailing lists involves the saving of - Microsoft Office files (Word and Excel) to a network drive. Here is the typical sequence: - </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p> - A user opens a Word document from a network drive.

Frequently Samba users - want to know when this <span class="quote">“<span class="quote">bug</span>”</span> will be fixed. The fact is, this is not a bug in Samba at all. - Here is the real sequence of what happens in this case. - </p><p><a class="indexterm" name="id380609"></a><a class="indexterm" name="id380617"></a><a class="indexterm" name="id380624"></a> - When the user saves a file, MS Word creates a new (temporary) file. This file is naturally owned - by the user who creates the file (<code class="constant">billc</code>) and has the permissions that follow - that user's default settings within the operating system (UNIX/Linux). When MS Word has finished writing - the file to disk, it then renames the new (temporary) file to the name of the old one. MS Word does not - change the ownership or permissions to what they were on the original file. The file is thus a totally - new file, and the old one has been deleted in the process. - </p><p> - Samba received a request to create a new file, and then to rename the file to a new name. The old file that - has the same name is now automatically deleted. Samba has no way of knowing that the new file should - perhaps have the same ownership and permissions as the old file. To Samba, these are entirely independent - operations. - </p><p> - The question is, <span class="quote">“<span class="quote">How can we solve the problem?</span>”</span> - </p><p> - The solution is simple. Use UNIX file system permissions and controls to your advantage.

For - example, one decision that can be made is to give each office its own master - file storage area that can be synchronized to a central repository in New - York. This would permit global data to be backed up from a single location. - The synchronization tool could be <code class="literal">rsync,</code> run via a cron - job.

A company with 3,500 employees, - 280 of whom are mobile users who use a similarly distributed - network, found they needed at least 2 Mb/sec connectivity - between the UK and US offices. Even over 2 Mb/sec bandwidth, this - company abandoned any attempt to run roaming profile usage for - mobile users.

This is immediately followed by registration of its - name both by broadcast and Unicast registration that is directed - at the WINS server. - </p><p> - <a class="indexterm" name="id353444"></a> - <a class="indexterm" name="id353450"></a><a class="indexterm" name="id353460"></a> - Given that the client is already a domain member, it then sends - a directed (Unicast) request to the WINS server seeking the list of - IP addresses for domain controllers (NetBIOS name type 0x1C). The - WINS server replies with the information requested.</p><p> - <a class="indexterm" name="id353472"></a> - <a class="indexterm" name="id353481"></a> - <a class="indexterm" name="id353488"></a> - The client sends two netlogon mailslot broadcast requests - to the local network and to each of the IP addresses returned by - the WINS server. Whichever answers this request first appears to - be the machine that the Windows XP client attempts to use to - process the network logon. The mailslot messages use UDP broadcast - to the local network and UDP Unicast directed at each machine that - was listed in the WINS server response to a request for the list of - domain controllers. - </p><p> - <a class="indexterm" name="id353502"></a> - <a class="indexterm" name="id353511"></a> - <a class="indexterm" name="id353518"></a> - The logon process begins with negotiation of the SMB/CIFS - protocols that are to be used; this is followed by an exchange of - information that ultimately includes the client sending the - credentials with which the user is attempting to logon. The logon - server must now approve the further establishment of the - connection, but that is a good point to halt for now. The priority - here must center around identification of network infrastructure - needs. A secondary fact we need to know is, what happens when - local domain controllers fail or break? - </p><p> - <a class="indexterm" name="id353533"></a> - <a class="indexterm" name="id353540"></a> - <a class="indexterm" name="id353546"></a> - <a class="indexterm" name="id353553"></a> - Under most circumstances, the nearest domain controller - responds to the netlogon mailslot broadcast. The exception to this - norm occurs when the nearest domain controller is too busy or is out - of service. Herein lies an important fact. This means it is - important that every network segment should have at least two - domain controllers. Since there can be only one PDC, all additional - domain controllers are by definition BDCs. - </p><p> - <a class="indexterm" name="id353566"></a> - <a class="indexterm" name="id353573"></a> - The provision of sufficient servers that are BDCs is an - important design factor. The second important design factor - involves how each of the BDCs obtains user authentication - data. That is the subject of the next section, which involves key - decisions regarding Identity Management facilities. - </p></div><div class="sect3" title="Identity Management Needs"><div class="titlepage"><div><div><h4 class="title"><a name="id353585"></a>Identity Management Needs</h4></div></div></div><p> - <a class="indexterm" name="id353593"></a> - <a class="indexterm" name="id353600"></a> - <a class="indexterm" name="id353606"></a> - <a class="indexterm" name="id353613"></a> - Network managers recognize that in large organizations users - generally need to be given resource access based on needs, while - being excluded from other resources for reasons of privacy. It is - therefore essential that all users identify themselves at the - point of network access.

Corporations that use a mixture - of systems soon discover that until recently, few systems were - designed to interoperate. For example, UNIX systems each have an - independent user database. Sun Microsystems developed a facility that - was originally called <code class="constant">Yellow Pages</code>, and was renamed - when a telephone company objected to the use of its trademark. - What was once called <code class="constant">Yellow Pages</code> is today known - as <code class="constant">Network Information System</code> (NIS). - </p><p> - <a class="indexterm" name="id353666"></a> - NIS gained a strong following throughout the UNIX/VMS space in a short - period of time and retained that appeal and use for over a decade. - Security concerns and inherent limitations have caused it to enter its - twilight. NIS did not gain widespread appeal outside of the UNIX world - and was not universally adopted.

Making Happy Users">“Making Happy Users”</a>, you implemented a single LDAP server for the - entire network. This may work for smaller networks, but almost - certainly fails to meet the needs of large and complex networks. The - following section documents how you may implement a single - master LDAP server with multiple slave servers.</p><p> - What is the best method for implementing master/slave LDAP - servers within the context of a distributed 2,000-user network is a - question that remains to be answered.</p><p> - <a class="indexterm" name="id353796"></a> - <a class="indexterm" name="id353803"></a> - One possibility that has great appeal is to create a single, - large distributed domain. The practical implications of this - design (see <a class="link" href="net2000users.html#chap7net" title="Figure 6.6. Network Topology 2000 User Complex Design A">“Network Topology 2000 User Complex Design A”</a>) demands the placement of - sufficient BDCs in each location. Additionally, network - administrators must make sure that profiles are not transferred - over the wide-area links, except as a totally unavoidable - measure. Network design must balance the risk of loss of user - productivity against the cost of network management and - maintenance. - </p><p> - <a class="indexterm" name="id353826"></a> - The network design in <a class="link" href="net2000users.html#chap7net2" title="Figure 6.7. Network Topology 2000 User Complex Design B">“Network Topology 2000 User Complex Design B”</a> takes the approach - that management of networks that are too remote to be managed - effectively from New York ought to be given a certain degree of - autonomy. With this rationale, the Los Angeles and London networks, - though fully integrated with those on the East Coast, each have their - own domain name space and can be independently managed and controlled. - One of the key drawbacks of this design is that it flies in the face of - the ability for network users to roam globally without some compromise - in how they may access global resources. - </p><p> - <a class="indexterm" name="id353848"></a> - Desk-bound users need not be negatively affected by this design, since - the use of interdomain trusts can be used to satisfy the need for global - data sharing. - </p><p> - <a class="indexterm" name="id353859"></a> - <a class="indexterm" name="id353866"></a> - <a class="indexterm" name="id353875"></a> - When Samba-3 is configured to use an LDAP backend, it stores the domain - account information in a directory entry. This account entry contains the - domain SID. An unintended but exploitable side effect is that this makes it - possible to operate with more than one PDC on a distributed network. - </p><p> - <a class="indexterm" name="id353887"></a> - <a class="indexterm" name="id353894"></a> - <a class="indexterm" name="id353901"></a> - How might this peculiar feature be exploited? The answer is simple. It is - imperative that each network segment have its own WINS server. Major - servers on remote network segments can be given a static WINS entry in - the <code class="filename">wins.dat</code> file on each WINS server. This allows - all essential data to be visible from all locations. Each location would, - however, function as if it is an independent domain, while all sharing the - same domain SID. Since all domain account information can be stored in a - single LDAP backend, users have unfettered ability to roam. - </p><p> - <a class="indexterm" name="id353921"></a> - <a class="indexterm" name="id353930"></a> - This concept has not been exhaustively validated, though we can see no reason - why this should not work. The important facets are the following: The name of - the domain must be identical in all locations. Each network segment must have - its own WINS server. The name of the PDC must be the same in all locations; this - necessitates the use of NetBIOS name aliases for each PDC so that they can be - accessed globally using the alias and not the PDC's primary name. A single master - LDAP server can be based in New York, with multiple LDAP slave servers located - on every network segment. Finally, the BDCs should each use failover LDAP servers - that are in fact slave LDAP servers on the local segments. - </p><p> - <a class="indexterm" name="id353946"></a> - <a class="indexterm" name="id353956"></a> - <a class="indexterm" name="id353962"></a> - <a class="indexterm" name="id353972"></a> - With a single master LDAP server, all network updates are effected on a single - server. In the event that this should become excessively fragile or network - bandwidth limiting, one could implement a delegated LDAP domain. This is also - known as a partitioned (or multiple partition) LDAP database and as a distributed - LDAP directory. - </p><p> - As the LDAP directory grows, it becomes increasingly important - that its structure is implemented in a manner that mirrors - organizational needs, so as to limit network update and - referential traffic. It should be noted that all directory - administrators must of necessity follow the same standard - procedures for managing the directory, because retroactive correction of - inconsistent directory information can be exceedingly difficult. - </p></div></div><div class="sect2" title="Political Issues"><div class="titlepage"><div><div><h3 class="title"><a name="id353997"></a>Political Issues</h3></div></div></div><p> - As organizations grow, the number of points of control increases - also. In a large distributed organization, it is important that the - Identity Management system be capable of being updated from - many locations, and it is equally important that changes made should - become usable in a reasonable period, typically - minutes rather than days (the old limitation of highly manual - systems). - </p></div></div><div class="sect1" title="Implementation"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id354011"></a>Implementation</h2></div></div></div><p> - <a class="indexterm" name="id354019"></a> - <a class="indexterm" name="id354026"></a> - <a class="indexterm" name="id354032"></a> - <a class="indexterm" name="id354039"></a> - Samba-3 has the ability to use multiple password (authentication and - identity resolution) backends.

Since the process involves going - through a certain amount of disruptive activity anyhow, why not take this opportunity to - review the structure of the network, how Windows clients are controlled and how they - interact with the network environment. - </p><p> - <a class="indexterm" name="id369237"></a> - <a class="indexterm" name="id369246"></a> - <a class="indexterm" name="id369253"></a> - MS Windows NT4 was introduced some time around 1996. Many environments in which NT4 was deployed - have done little to keep the NT4 server environment up to date with more recent Windows releases, - particularly Windows XP Professional. The migration provides opportunity to revise and update - roaming profile deployment as well as folder redirection. Given that you must port the - greater network configuration of this from the old NT4 server to the new Samba-3 server. - Do not forget to validate the security descriptors in the profiles share as well as network logon - scripts. Feedback from sites that are migrating to Samba-3 suggests that many are using this - as a good time to update desktop systems also. In all, the extra effort should constitute no - real disruption to users, but rather, with due diligence and care, should make their network experience - a much happier one. - </p><div class="sect2" title="Technical Issues"><div class="titlepage"><div><div><h3 class="title"><a name="id369276"></a>Technical Issues</h3></div></div></div><p> - <a class="indexterm" name="id369284"></a> - <a class="indexterm" name="id369291"></a> - Migration of an NT4 domain user and group database to Samba-3 involves a certain strategic - element. Many sites have asked for instructions regarding merging of multiple NT4 - domains into one Samba-3 LDAP database. It seems that this is viewed as a significant - added value compared with the alternative of migration to Windows Server 200x and Active - Directory. The diagram in <a class="link" href="ntmigration.html#ch8-migration" title="Figure 9.1.

Now clean - out (remove) the tdbsam backend file (<code class="filename">passdb.tdb</code>) or the LDAP database - files. You must start each migration with a new database into which you merge your NT4 - domains. - </p><p><a class="indexterm" name="id369383"></a> - At this point, you are ready to perform the second migration, following the same steps as - for the first.

This automatically strips out all domain-specific information, - such as logon hours, logon machines, logon script, profile path, as well as the domain SID. - The resulting file can be easily merged with other migration attempts (each of which must start - with a clean file). It should also be noted that all users who end up in the merged smbpasswd - file must have an account in <code class="filename">/etc/passwd</code>. The resulting smbpasswd file - may be exported or imported into either a tdbsam (<code class="filename">passdb.tdb</code>) or - an LDAP backend. - </p><div class="figure"><a name="NT4DUM"></a><p class="title"><b>Figure 9.2.

Novell's SUSE Linux hosts the NetWare server and it is the - platform of choice to which many older NetWare servers are being migrated. - It will be interesting to see what becomes of NetWare over time. - Meanwhile, there can be no denying that Novell is a Linux company. - </p><p> - <a class="indexterm" name="id373073"></a> - <a class="indexterm" name="id373080"></a> - <a class="indexterm" name="id373087"></a> - <a class="indexterm" name="id373093"></a> - Whatever flavor of Linux is preferred in your environment, whether Red Hat, Debian, - Gentoo, Mandrake, or SUSE (Novell), the information in this chapter should be read with - the knowledge that file locations may vary a little; even so, the information - in this chapter should provide something of value. - </p><p> - <a class="indexterm" name="id373106"></a> - Contributions to this chapter were made by Misty Stanley-Jones, a UNIX administrator of many - years who surfaced on the Samba mailing list with a barrage of questions and who - regularly helps other administrators to solve thorny Samba migration questions. - </p><p> - <a class="indexterm" name="id373118"></a> - <a class="indexterm" name="id373125"></a> - <a class="indexterm" name="id373132"></a> - <a class="indexterm" name="id373139"></a> - One wonders how many NetWare servers remain in active service. Many are being migrated - to Samba on Linux. Red Hat Linux, SUSE Linux 9.x, and SUSE Linux Enterprise Server 9 are - ideal target platforms to which a NetWare server may be migrated. The migration method - of choice is much dependent on the tools that the administrator finds most natural to use. - The old-hand NetWare guru will likely want to use tools like the NetWare NLM for - <code class="literal">rsync</code> to migrate files from the NetWare server to the Samba server. - The UNIX administrator might prefer tools that are part of the Mars_NWE (Martin Stovers' NetWare - Emulator) open source package. The MS Windows network administrator will likely make use of the - NWConv utility that is a part of Windows NT4 Server. Whatever your tool of choice, - migration will be filled with joyous and challenging moments though probably not - concurrently. - </p><p> - The priority that Misty faced was one of migration of the data files off the NetWare 4.11 - server and onto a Samba-based Windows file and print server. This chapter does not pretend - to document all the different methods that could be used to migrate user and group accounts - off a NetWare server. Its focus is on migration of data files. - </p><p> - This chapter tells its own story, so ride along. Maybe the information presented here - will help to smooth over a similar migration challenge in your favorite networking environment. - </p><p> - File paths have been modified to permit use of RPM packages provided by Novell. In the - original documentation contributed by Misty, the Courier-IMAP package had been built - directly from the original source tarball. - </p><div class="sect1" title="Introduction"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id373183"></a>Introduction</h2></div></div></div><p> - <a class="indexterm" name="id373190"></a> - Misty Stanley-Jones was recruited by Abmas to administer a network that had - not received much attention for some years and was much in need of a makeover. - As a brand-new sysadmin to this company, she inherited a very old Novell file server - and came with a determination to change things for the better. - </p><p> - A site survey turned up the following details for the old NetWare server: - </p><table border="0" summary="Simple list" class="simplelist"><tr><td>200 MHz MMX processor</td></tr><tr><td>512K RAM</td></tr><tr><td>24 GB disk space in RAID1</td></tr><tr><td>Novell 4.11 patched to service pack 7</td></tr><tr><td>60+ users</td></tr><tr><td>7 network-attached printers</td></tr></table><p> - The company had outgrown this server several years before and was dealing with - severe growing pains. Some of the problems experienced were: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>Very slow performance</p></li><li class="listitem"><p>Available storage hovering around the 5% range</p><div class="itemizedlist"><ul class="itemizedlist" type="circle"><li class="listitem"><p>Extremely slow print spooling.</p></li><li class="listitem"><p> - Users storing information on their local hard - drives, causing backup integrity problems - </p></li></ul></div></li></ul></div><p> - <a class="indexterm" name="id373272"></a> - At one point disk space had filled up to 100 percent, causing the payroll database - to become corrupt. This caused the accounting department to be down for over - a week and necessitated deployment of another file server. The replacement - server was created with very poor security and design considerations from - a discarded desktop PC. - </p><div class="sect2" title="Assignment Tasks"><div class="titlepage"><div><div><h3 class="title"><a name="id373282"></a>Assignment Tasks</h3></div></div></div><p> - Misty has provided this summary of her migration experience in the hope - that it will help someone to avoid the challenges she faced. Perhaps her - configuration files and background will accelerate your learning as you - grapple with a similar migration challenge. Let there be no confusion, - the information presented in this chapter is provided to demonstrate - how Misty dealt with a particular NetWare migration requirement, and - it provides an overall approach to the implementation of a Samba-3 - environment that is significantly divergent from that presented in - <a class="link" href="happy.html" title="Chapter 5. Making Happy Users">“Making Happy Users”</a>. - </p><p> - The complete removal of all site-specific information in order to produce - a generic migration solution would rob this chapter of its character. - It should be recognized, therefore, that the examples given require - significant adaptation to suit local needs and thus - there are some gaps in the example files. That is not Misty's fault;it - is the result of treatment given to her files in an attempt to make - the overall information more useful to you. - </p><p> - <a class="indexterm" name="id373311"></a> - After management reviewed a cost-benefit report as well as an estimated - time-to-completion, approval was given proceed with the solution proposed. - The server was built from purchased components. The total project cost - was $3,000. A brief description of the configuration follows: - </p><table border="0" summary="Simple list" class="simplelist"><tr><td> - 3.0 GHz P4 Processor - </td></tr><tr><td> - 1 GB RAM - </td></tr><tr><td> - 120 GB SATA operating system drive - </td></tr><tr><td> - 4 x 80 GB SATA data drives (RAID5 240 GB capacity) - </td></tr><tr><td> - 2 x 80 GB SATA removable drives for online backup - </td></tr><tr><td> - A DLT drive for asynchronous offline backup - </td></tr><tr><td> - SUSE Linux Professional 9.1 - </td></tr></table><p> - The new system has operated for 6 months without problems.

Following - the guidance I obtained from <span class="quote">“<span class="quote">LDAP System - Administration,</span>”</span> I installed OpenLDAP (from RPM; later I compiled - a more current version from source) and built my initial LDAP tree. - </p><div class="sect2" title="Technical Issues"><div class="titlepage"><div><div><h3 class="title"><a name="id373431"></a>Technical Issues</h3></div></div></div><p> - <a class="indexterm" name="id373439"></a> - <a class="indexterm" name="id373446"></a> - <a class="indexterm" name="id373452"></a> - <a class="indexterm" name="id373459"></a> - <a class="indexterm" name="id373466"></a> - <a class="indexterm" name="id373473"></a> - <a class="indexterm" name="id373480"></a> - <a class="indexterm" name="id373486"></a> - <a class="indexterm" name="id373493"></a> - The first challenge was to create a company white pages, followed by manually - entering everything from the printed company directory. This used only the inetOrgPerson - object class from the OpenLDAP schemas. The next step was to write a shell script that - would look at the <code class="filename">/etc/passwd</code> and <code class="filename">/etc/shadow</code> - files on our mail server and create an LDIF file from which the information could be - imported into LDAP. This would allow use of LDAP for Linux authentication, IMAP, POP3, - and SMTP. - </p><p> - Because a decision was made to use Courier-IMAP the schema <span class="quote">“<span class="quote">authldap.schema</span>”</span> - from the Courier-IMAP source, tarball is necessary to resolve Courier-specific LDAP directory - needs. Where the Courier-IMAP file provided by SUSE is used, this file is named - <code class="filename">courier.schema</code>. - </p><p> - Looking back, it would have been much easier to populate the LDAP directory using a convenient - tool such as <code class="literal">phpLDAPAdmin</code> from the outset. An excessive amount of time was - spent trying to generate LDIF files that could be parsed using the <code class="literal">ldapmodify</code> - so that necessary changes could be written to the directory. This was a learning experience! - </p><p> - An attempt was made to use the PADL POSIX account migration scripts, but I gave up trying to - make them work. Instead, even though it is most inelegant, I wrote a simple script that did - what I needed. It is enclosed as a simple example to demonstrate that you do not need to be - a guru to make light of otherwise painful repetition.

All of his or her settings and all contents of My Documents, - Favorites, and the registry should have been copied successfully. - </p></li><li class="step" title="Step 7"><p> - If it doesn't look right (the dead giveaway is the desktop background), - shut down the computer without logging out (power cycle) and try logging - in as the user again. If it still doesn't work, repeat the steps above. - I only had to ever repeat it once. - </p></li></ol></div><p> - Words to the Wise: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - If the user was anything other than a standard user on his or her system - before, you will save yourself some headaches by giving him or her identical - permissions (on the local machine) as his or her domain account <span class="emphasis"><em>before</em></span> - copying the profile over. Do this through the User Administrator - in the Control Panel, after joining the computer to the domain and - before logging on as that user for the first time. Otherwise the user will - have trouble with permissions on his or her registry keys. - </p></li><li class="listitem"><p> - If any application was installed for the user only, rather than for - the entire system, it will probably not work without being reinstalled. - </p></li></ul></div><p> - After all these steps are accomplished, only cleanup details are left. Make sure user's - shortcuts and Network Places point to the appropriate place on the new server, check - the important applications to be sure they work as expected and troubleshoot any problems - that might arise, and check to be sure the user's printers are present and working. By the - way, if there are any network printers installed as system printers (the Novell way), - you will need to log in as a local administrator and delete them. - </p><p> - For my non-laptop systems, I would then log in and out a couple times as the user - to be sure that his or her registry settings were modified, and then I was finished. - </p><p> - Some compatibility issues that cropped up included the following: - </p><p> - Blackberry client: It did not like having its registry settings moved around - and so had to be reinstalled. Also, it needed write permissions to a portion of - the hard drive, and I had to give it those manually on the one system where - this was an issue. - </p><p> - CAMedia: Digital camera software for Canon cameras caused all kinds of trouble - with the registry. I had to use the Run as service to open the registry of - the local user while logged in as the domain user, and give the domain user - the appropriate permissions to some registry keys, then export that portion - of the registry to a file. Then, as the domain user, I had to import that file - into the registry. - </p><p> - Crystal Reports version 7: More registry problems that were solved by recopying - the user's profile. - </p><p> - Printing from legacy applications: I found out that Novell sends its jobs to - the printer in a raw format. CUPS sends them in PostScript by default. I had - to make a second printer definition for one printer and tell CUPS specifically - to send raw data to the printer, then assign this printer to the LPT port with - Kixtart's version of the net use command. - </p><p> - These were all eventually solved by elbow grease, queries to the Samba mailing - list and others, and diligence. The complete migration took about 5 weeks. - My userbase is relatively small but includes multiple versions of Windows, - multiple Linux member servers, a mechanized saw, a pen plotter, and legacy - applications written in Qbasic and R:Base, just to name a few. I actually - ended up making some of these applications work better (or work again, as - some of them had stopped functioning on the old server) because as part of - the process I had to find out how things were supposed to work. - </p><p> - The one thing I have not been able to get working is a very old database that - we had around for reference purposes; it uses Novell's Btrieve engine. - </p><p> - As the resources compare, I went from 95 percent disk usage to just around 10 percent. - I went from a very high load on the server to an average load of between one - and two runnable processes on the server.

The history of civilization - demonstrates the fragile nature of freedom. It can be lost in a moment, - and once lost, the cost of recovering liberty can be incredible. The last - edition cover featured Alfred the Great who liberated England from the - constant assault of Vikings and Norsemen. Events in England that - finally liberated the common people came about in small steps, but - the result should not be under-estimated.

Our affiliate in the United Kingdom is the -Open Source Consortium (OSC). Both the OSSI and the OSC share a common objective to expand the use of open source -software in federal, state, and municipal government agencies; and in academic institutions. We represent -businesses that provide professional support services that answer the needs of our target organizational -information technology consumers in an effective and cost-efficient manner. -</p><p> -Open source software has matured greatly over the past five years with the result that an increasing number of -people who hold key decisionmaking positions want to know how the business model works. They -want to understand how problems get resolved, how questions get answered, and how the development model -is sustained. Information and communications technology directors in defense organizations, and in other -government agencies that deal with sensitive information, want to become familiar with development road-maps -and, in particular, seek to evaluate the track record of the mainstream open source project teams. -</p><p> -Wherever the OSSI gains entrance to new opportunities we find that Microsoft Windows technologies are the -benchmark against which open source software solutions are measured. Two open source software projects -are key to our ability to present a structured and convincing proposition that there are alternatives -to the incumbent proprietary means of meeting information technology needs. They are the Apache Web Server -and Samba. -</p><p> -Just as the Apache Web Server is the standard in web serving technology, Samba is the definitive standard -for providing interoperability with UNIX systems and other non-Microsoft operating system platforms. Both -open source applications have a truly remarkable track record that extends for more than a decade. Both have -demonstrated the unique capacity to innovate and maintain a level of development that has not only kept -pace with demands, but, in many areas, each project has also proven to be an industry leader. -</p><p> -One of the areas in which the Samba project has demonstrated key leadership is in documentation. The OSSI -was delighted when we saw the Samba Team, and John H. Terpstra in particular, release two amazingly -well-written books to help Samba software users deploy, maintain, and troubleshoot Windows networking -installations. We were concerned that, given the large volume of documentation, the challenge to maintain -it and keep it current might prove difficult. -</p><p> -This second edition of the book, <span class="emphasis"><em>Samba-3 by Example</em></span>, barely one year following the release -of the first edition, has removed all concerns and is proof that open source solutions are a compelling choice. -The first edition was released shortly following the release of Samba version 3.0 itself, and has become -the authoritative instrument for training and for guiding deployment. -</p><p> -I am personally aware of how much effort has gone into this second edition. John Terpstra has worked with -government bodies and with large organizations that have deployed Samba-3 since it was released. He also -worked to ensure that this book gained community following. He asked those who have worked at the coalface -of large and small organizations alike, to contribute their experiences. He has captured that in this book -and has succeeded yet again. His recipe is persistence, intuition, and a high level of respect for the people -who use Samba. -</p><p> -This book is the first source you should turn to before you deploy Samba and as you are mastering its -deployment. I am proud and excited to be associated in a small way with such a useful tool. This book has -reached maturity that is demonstrated by reiteration that every step in deployment must be validated. -This book makes it easy to succeed, and difficult to fail, to gain a stable network environment. -</p><p> -I recommend this book for use by all IT managers and network administrators. -</p></blockquote></div></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="pr02.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="preface.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Acknowledgments </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Preface</td></tr></table></div></body></html> diff --git a/docs/htmldocs/Samba3-ByExample/preface.html b/docs/htmldocs/Samba3-ByExample/preface.html deleted file mode 100644 index d2d301de68..0000000000 --- a/docs/htmldocs/Samba3-ByExample/preface.html +++ /dev/null @@ -1,386 +0,0 @@ -<html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Preface</title><link rel="stylesheet" href="../samba.css" type="text/css"><meta name="generator" content="DocBook XSL Stylesheets V1.75.2"><link rel="home" href="index.html" title="Samba-3 by Example"><link rel="up" href="index.html" title="Samba-3 by Example"><link rel="prev" href="pr03.html" title="Foreword"><link rel="next" href="ExNetworks.html" title="Part I.

There is a - saying that, geometrically speaking, the shortest distance between two - points is a straight line, but practically we find that the quickest - route to a stable network solution is the long way around. - </p><p> - This book is your means to the straight path. It provides step-by-step, - proven, working examples of Samba deployments. If you want to deploy - Samba-3 with the least effort, or if you want to become an expert at deploying - Samba-3 without having to search through lots of documentation, this - book is the ticket to your destination. - </p><p> - Samba is software that can be run on a platform other than Microsoft Windows, - for example, UNIX, Linux, IBM System 390, OpenVMS, and other operating systems. - Samba uses the TCP/IP protocol that is installed on the host server. When - correctly configured, it allows that host to interact with a Microsoft Windows - client or server as if it is a Windows file and print server. This book - will help you to implement Windows-compatible file and print services. - </p><p> - The examples presented in this book are typical of various businesses and - reflect the problems and challenges they face. Care has been taken to preserve - attitudes, perceptions, practices, and demands from real network case studies. - The maximum benefit may be obtained from this book by working carefully through - each exercise. You may be in a hurry to satisfy a specific need, so feel - free to locate the example that most closely matches your need, copy it, and - innovate as much as you like. Above all, enjoy the process of learning the - secrets of MS Windows networking that is truly liberated by Samba. - </p><p> - The focus of attention in this book is Samba-3. Specific notes are made in - respect of how Samba may be made secure. This book does not attempt to provide - detailed information regarding secure operation and configuration of peripheral - services and applications such as OpenLDAP, DNS and DHCP, the need for which - can be met from other resources that are dedicated to the subject. - </p><div class="sect1" title="Why Is This Book Necessary?"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id280788"></a>Why Is This Book Necessary?</h2></div></div></div><p> - This book is the result of observations and feedback.

Access to the server is tightened up - so that only domain members can access server resources. Mobile computing - needs still are catered to. - </p></dd><dt><span class="term">Chapter 4 The 500 User Office.</span></dt><dd><p> - The two-year projections were met. Congratulations, you are a star. - Now Abmas needs to replace the network. Into the existing user base, they - need to merge a 280-user company they just acquired. It is time to build a serious - network. There are now three buildings on one campus and your assignment is - to keep everyone working while a new network is rolled out. Oh, isn't it nice - to roll out brand new clients and servers! Money is no longer tight, you get - to buy and install what you ask for.

Also required is one additional server (either Windows - NT4 Server, Windows 2000 Server, or a Samba-3 on UNIX/Linux server) running a network - sniffer and analysis application (Wireshark is a good choice). All work should be undertaken - on a quiet network where there is no other traffic. It is best to use a dedicated hub - with only the machines under test connected at the time of the exercises. - </p><p><a class="indexterm" name="id390642"></a> - Wireshark (formerly Ethereal) has become the network protocol analyzer of choice for many network administrators. - You may find more information regarding this tool from the - <a class="ulink" href="http://www.wireshark.org" target="_top">Wireshark</a> Web site. Wireshark installation - files for Windows may be obtained from the Wireshark Web site. Wireshark is provided with - SUSE and Red Hat Linux distributions, as well as with many other Linux distributions. It may - not be installed on your system by default.

It also demonstrates that an authenticated - connection must be made before resources can be used. - </p></div></div><div class="sect2" title="Conclusions to Exercises"><div class="titlepage"><div><div><h3 class="title"><a name="id393121"></a>Conclusions to Exercises</h3></div></div></div><p> - In summary, the following points have been established in this chapter: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - When NetBIOS over TCP/IP protocols are enabled, MS Windows networking employs broadcast-oriented messaging protocols to provide knowledge of network services. - </p></li><li class="listitem"><p> - Network browsing protocols query information stored on browse masters that manage - information provided by NetBIOS Name Registrations and by way of ongoing host - announcements and workgroup announcements. - </p></li><li class="listitem"><p> - All Samba servers must be configured with a mechanism for mapping the <code class="constant">NULL-Session</code> - to a valid but nonprivileged UNIX system account. - </p></li><li class="listitem"><p> - The use of Microsoft encrypted passwords is built right into the fabric of Windows - networking operations.

You started out - with three simple networks in <a class="link" href="simple.html" title="Chapter 1. No-Frills Samba Servers">“No-Frills Samba Servers”</a>, and then in <a class="link" href="small.html" title="Chapter 2. Small Office Networking">“Small Office Networking”</a> - you designed and built a network that provides a high degree of flexibility, integrity, - and dependability. It was enough for the basic needs each was designed to fulfill. In - this chapter you address a more complex set of needs. The solution you explore - introduces you to basic features that are specific to Samba-3. - </p><p> - You should note that a working and secure solution could be implemented using Samba-2.2.x. - In the exercises presented here, you are gradually using more Samba-3-specific features, - so caution is advised for anyone who tries to use Samba-2.2.x with the guidance here given. - To avoid confusion, this book is all about Samba-3. Let's get the exercises in this - chapter underway. - </p><div class="sect1" title="Introduction"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id330143"></a>Introduction</h2></div></div></div><p> - You have made Mr. Meany a very happy man. Recently he paid you a fat bonus for work - well done. It is one year since the last network upgrade. You have been quite busy. - Two months ago Mr. Meany gave approval to hire Christine Roberson, who has taken over - general network management. Soon she will provide primary user support. You have - demonstrated that you can delegate responsibility and can plan and execute according - to that plan. Above all, you have shown Mr. Meany that you are a responsible person. - Today is a big day. Mr. Meany called you to his office at 9 a.m. for news you never - expected: You are going to take charge of business operations. Mr. Meany - is retiring and has entrusted the business to your capable hands. - </p><p> - Mr. Meany may be retiring from this company, but not from work. He is taking the - opportunity to develop Abmas Accounting into a larger and more substantial company. - He says that it took him many years to learn that there is no future in just running - a business. He now realizes there is great personal satisfaction in the creation of - career opportunities for people in the local community. He wants to do more for others, - as he is doing for you. Today he spent a lot of time talking about his grand plan - for growth, which you will deal with in the chapters ahead. - </p><p> - Over the past year, the growth projections were exceeded. The network has grown to - meet the needs of 130 users. Along with growth, the demand for improved services - and better functionality has also developed. You are about to make an interim - improvement and then hand over all Help desk and network maintenance to Christine. - Christine has professional certifications in Microsoft Windows as well as in Linux; - she is a hard worker and quite likable. Christine does not want to manage the department - (although she manages well). She gains job satisfaction when left to sort things out. - Occasionally she wants to work with you on a challenging problem. When you told her - about your move, she almost resigned, although she was reassured that a new manager would - be hired to run Information Technology, and she would be responsible only for operations. - </p><div class="sect2" title="Assignment Tasks"><div class="titlepage"><div><div><h3 class="title"><a name="id330177"></a>Assignment Tasks</h3></div></div></div><p> - You promised the staff Internet services including Web browsing, electronic mail, virus - protection, and a company Web site. Christine is eager to help turn the vision into - reality. Let's see how close you can get to the promises made. - </p><p> - The network you are about to deliver will service 130 users today. Within a year, - Abmas will aquire another company. Mr. Meany claims that within 2 years there will be - well over 500 users on the network. You have bought into the big picture, so prepare - for growth. You have purchased a new server and will implement a new network infrastructure. - </p><p> - You have decided to not recycle old network components. The only items that will be - carried forward are notebook computers. You offered staff new notebooks, but not - one person wanted the disruption for what was perceived as a marginal update. - You decided to give everyone, even the notebook user, a new desktop computer. - </p><p> - You procured a DSL Internet connection that provides 1.5 Mb/sec (bidirectional) - and a 10 Mb/sec ethernet port. You registered the domain - <code class="constant">abmas.us</code>, and the Internet Service Provider (ISP) is supplying - secondary DNS. Information furnished by your ISP is shown in <a class="link" href="secure.html#chap4netid" title="Table 3.1. Abmas.US ISP Information">“Abmas.US ISP Information”</a>. - </p><p> - It is of paramount priority that under no circumstances will Samba offer - service access from an Internet connection. You are paying an ISP to - give, as part of its value-added services, full firewall protection for your - connection to the outside world. The only services allowed in from - the Internet side are the following destination ports: <code class="constant">http/https (ports - 80 and 443), email (port 25), DNS (port 53)</code>.

This, - of course, limits our network to a maximum of 253 usable IP addresses. The network - address range chosen is one assigned by RFC1918 for private networks. - When the number of users on the network begins to approach the limit of usable - addresses, it is a good idea to switch to a network address specified in RFC1918 - in the 172.16.0.0/16 range.

This design is often chosen by sites that feel - they cannot afford or justify the cost or overhead of having separate servers. It must - be realized that if security of this type of server should ever be violated (compromised), - the whole network and all data is at risk. Many sites continue to choose this type - of solution; therefore, this chapter provides detailed coverage of key implementation - aspects. - </p><p> - Samba will be configured to specifically not operate on the Ethernet interface that is - directly connected to the Internet. - </p><p> - <a class="indexterm" name="id330462"></a> - <a class="indexterm" name="id330469"></a> - <a class="indexterm" name="id330475"></a> - <a class="indexterm" name="id330483"></a> - You know that your ISP is providing full firewall services, but you cannot rely on that. - Always assume that human error will occur, so be prepared by using Linux firewall facilities - based on <code class="literal">iptables</code> to effect NAT.

All printers are configured as DHCP clients so that the DHCP server assigns - the printer a fixed IP address by way of the Ethernet interface (MAC) address. One additional - feature of this DHCP server configuration file is the inclusion of parameters to allow dynamic - DNS (DDNS) operation. - </p><p> - This is the first implementation that depends on a correctly functioning DNS server. - Comprehensive steps are included to provide for a fully functioning DNS server that also - is enabled for DDNS operation. This means that DHCP clients can be autoregistered - with the DNS server. - </p><p> - You are taking the opportunity to manually set the netbios name of the Samba server to - a name other than what will be automatically resolved. You are doing this to ensure that - the machine has the same NetBIOS name on both network segments. - </p><p> - As in the previous network configuration, printing in this network configuration uses - direct raw printing (i.e., no smart printing and no print driver autodownload to Windows - clients). Printer drivers are installed on the Windows client manually.

You must add an account for each network user. - For each user who needs to be given a Windows Domain account, make an entry in the - <code class="filename">/etc/passwd</code> file as well as in the Samba password backend. - Use the system tool of your choice to create the UNIX system account, and use the Samba - <code class="literal">smbpasswd</code> to create a Domain user account. - There are a number of tools for user management under UNIX, such as - <code class="literal">useradd</code>, and <code class="literal">adduser</code>, as well as a plethora of custom - tools. You also want to create a home directory for each user. - You can do this by executing the following steps for each user: -</p><pre class="screen"> -<code class="prompt">root# </code> useradd -m <em class="parameter"><code>username</code></em> -<code class="prompt">root# </code> passwd <em class="parameter"><code>username</code></em> -Changing password for <em class="parameter"><code>username</code></em>. -New password: XXXXXXXX -Re-enter new password: XXXXXXXX -Password changed -<code class="prompt">root# </code> smbpasswd -a <em class="parameter"><code>username</code></em> -New SMB password: XXXXXXXX -Retype new SMB password: XXXXXXXX -Added user <em class="parameter"><code>username</code></em>. -</pre><p> - You do of course use a valid user login ID in place of <em class="parameter"><code>username</code></em>. - </p></li><li class="step" title="Step 7"><p> - <a class="indexterm" name="id332838"></a> - <a class="indexterm" name="id332846"></a> - <a class="indexterm" name="id332854"></a> - Using the preferred tool for your UNIX system, add each user to the UNIX groups created - previously as necessary. File system access control will be based on UNIX group membership. - </p></li><li class="step" title="Step 8"><p> - Create the directory mount point for the disk subsystem that can be mounted to provide - data storage for company files. In this case the mount point is indicated in the <code class="filename">smb.conf</code> - file is <code class="filename">/data</code>. Format the file system as required, and mount the formatted - file system partition using appropriate system tools. - </p></li><li class="step" title="Step 9"><p> - <a class="indexterm" name="id332889"></a> - Create the top-level file storage directories for data and applications as follows: -</p><pre class="screen"> -<code class="prompt">root# </code> mkdir -p /data/{accounts,finsrvcs} -<code class="prompt">root# </code> mkdir -p /apps -<code class="prompt">root# </code> chown -R root:root /data -<code class="prompt">root# </code> chown -R root:root /apps -<code class="prompt">root# </code> chown -R bjordan:acctsdep /data/accounts -<code class="prompt">root# </code> chown -R bjordan:finsrvcs /data/finsrvcs -<code class="prompt">root# </code> chmod -R ug+rwxs,o-rwx /data -<code class="prompt">root# </code> chmod -R ug+rwx,o+rx-w /apps -</pre><p> - Each department is responsible for creating its own directory structure within the departmental - share.

You can now create the file system infrastructure to provide the - locations on disk that these services require. Adequate planning is essential, - since desktop profiles can grow to be quite large. For planning purposes, a minimum of - 200 MB of storage should be allowed per user for profile storage.

A practical limit would come into - play long before a performance boundary would be anticipated. That practical limit - is controlled by the nature of Windows networking. There are few Windows file and - print servers that can handle more than a few hundred concurrent client connections. - The key limiting factors that predicate offloading of services to additional servers - are memory capacity, the number of CPUs, network bandwidth, and disk I/O limitations. - All of these are readily exhausted by just a few hundred concurrent active users. - Such bottlenecks can best be removed by segmentation of the network (distributing - network load across multiple networks). - </p><p> - As the network grows, it becomes necessary to provide additional authentication - servers (domain controllers). The tdbsam is limited to a single machine and cannot - be reliably replicated.

This is the point - at which most networks tend to want backup domain controllers (BDCs). Samba-3 does - not provide a mechanism for replicating tdbsam data so it can be used by a BDC.

This office - has five networked computers. Staff are all volunteers, staff changes are frequent. - Ms. Amy May, the director of operations, wants a no-hassle network. Anyone should be able to - use any PC. Only two Windows applications are used: a custom funds tracking and management package - that stores all files on the central server and Microsoft Word. The office prepares mail-out - letters, invitations, and thank-you notes. All files must be stored in perpetuity. - The custom funds tracking and management (FTM) software is configured to use a server named - <code class="constant">SERVER</code>, a share named <code class="constant">FTMFILES</code>, and a printer queue - named <code class="constant">PRINTQ</code> that uses preprinted stationery, thus demanding a - dedicated printer. This printer does not need to be mapped to a local printer on the workstations. - </p><p> - The FTM software has been in use since the days of Windows 3.11. The software was configured - by the vendor who has since gone out of business. The identities of the file - server and the printer are hard-coded in a configuration file that was created using a - setup tool that the vendor did not provide to Abmas Vision NL or to its predecessors. The - company that produced the software is no longer in business. In order to avoid risk of - any incompatibilities, the share name and the name of the target print queue must be set - precisely as the application expects. In fact, share names and print queue names - should be treated as case insensitive (i.e., case does not matter), but Abmas Vision advises - that if the share name is not in lowercase, the application claims it cannot find the - file share. - </p><p> - <a class="indexterm" name="id323847"></a> - <a class="indexterm" name="id323854"></a> - Printer handling in Samba results in a significant level of confusion. Samba presents to the - MS Windows client only a print queue. The Samba <code class="literal">smbd</code> process passes a - print job sent to it from the Windows client to the native UNIX printing system. The native - UNIX printing system (spooler) places the job in a print queue from which it is - delivered to the printer. In this book, network diagrams refer to a printer by the name - of the print queue that services that printer. It does not matter what the fully qualified - name (or the hostname) of a network-attached printer is. The UNIX print spooler is configured - to correctly deliver all jobs to the printer. - </p><p> - This organization has a policy forbidding use of privately owned computers on site as a measure - to prevent leakage of confidential information. Only the five PCs owned by Abmas Vision NL are - used on this network. - </p><p> - <a class="indexterm" name="id323879"></a> - The central server was donated by a local computer store. It is a dual processor Pentium-III - server, has 1GB RAM, a 3-Ware IDE RAID Controller that has four 200GB IDE hard drives, and a - 100-base-T network card. The office has 100-base-T permanent network connections that go to - a central hub, and all equipment is new. The five network computers all are equipped with Microsoft - Windows Me. Funding is limited, so the server has no operating system on it. You have approval - to install Samba on Linux, provided it works without problems. There are two HP LaserJet - 5 PS printers that are network connected. The second printer is to be used for general - office and letter printing. Your recommendation to allow only the Linux server to print directly - to the printers was accepted. You have supplied SUSE Enterprise Linux Server 9 and - have upgraded Samba to version 3.0.20. - </p><div class="sect3" title="Dissection and Discussion"><div class="titlepage"><div><div><h4 class="title"><a name="id323894"></a>Dissection and Discussion</h4></div></div></div><p> - <a class="indexterm" name="id323902"></a> - <a class="indexterm" name="id323908"></a> - <a class="indexterm" name="id323914"></a> - <a class="indexterm" name="id323920"></a> - This installation demands simplicity. Frequent turnover of volunteer staff indicates that - a network environment that requires users to logon might be problematic. It is suggested that the - best solution for this office would be one where the user can log onto any PC with any username - and password. Samba can accommodate an office like this by using the <em class="parameter"><code>force user</code></em> - parameter in share and printer definitions. Using the <em class="parameter"><code>force user</code></em> - parameter ensures that all files are owned by same user identifier (UID) and thus that there - will never be a problem with file access due to file access permissions. Additionally, you elect - to use the <em class="parameter"><code>nt acl support = No</code></em> option to ensure that - access control lists (Posix type) cannot be written to any file or directory. This prevents - an inadvertent ACL from overriding actual file permissions. - </p><p> - <a class="indexterm" name="id323953"></a> - <a class="indexterm" name="id323959"></a> - <a class="indexterm" name="id323965"></a> - This organization is a prime candidate for Share Mode security. The <em class="parameter"><code>force user</code></em> - allows all files to be owned by the same user and group. In addition, it would not hurt to - set SUID and set SGID shared directories. This means that all new files that are created, no matter - who creates it, are owned by the owner or group of the directory in which they are created. - For further information regarding the significance of the SUID/SGID settings, see <a class="link" href="appendix.html" title="Chapter 15. A Collection of Useful Tidbits">“A Collection of Useful Tidbits”</a>, <a class="link" href="appendix.html#ch12-SUIDSGID" title="Effect of Setting File and Directory SUID/SGID Permissions Explained">“Effect of Setting File and Directory SUID/SGID Permissions Explained”</a>. - </p><p> - <a class="indexterm" name="id323994"></a> - <a class="indexterm" name="id324000"></a> - <a class="indexterm" name="id324009"></a> - <a class="indexterm" name="id324015"></a> - All client workstations print to a print queue on the server. This ensures that print jobs - continue to print in the event that a user shuts down the workstation immediately after - sending a job to the printer. Today, both Red Hat Linux and SUSE Linux use CUPS-based printing. - Older Linux systems offered a choice between the LPRng printing system or CUPS. It appears, however, - that CUPS has become the leading UNIX printing technology. - </p><p> - <a class="indexterm" name="id324028"></a> - The print queues are set up as <code class="constant">Raw</code> devices, which means that CUPS will - not do intelligent print processing, and vendor-supplied drivers must be installed locally on the - Windows clients. - </p><p> - The hypothetical software, FTM, is representative of - custom-built software that directly uses a NetBIOS interface. Most such software originated in - the days of MS/PC DOS. NetBIOS names are uppercase (and functionally are case insensitive), - so some old software applications would permit only uppercase names to be entered. - Some such applications were later ported to MS Windows but retain the uppercase network - resource naming conventions because customers are familiar with that. We made the decision - to name shares and print queues for this application in uppercase for the same reason. - Nothing would break if we were to use lowercase names, but that decision might create a need - to retrain staff something well avoided at this time. - </p><p> - NetBIOS networking does not print directly to a printer. Instead, all printing is done to a - print queue. The print spooling system is responsible for communicating with the physical - printer. In this example, therefore, the resource called <code class="constant">PRINTQ</code> - really is just a print queue. The name of the print queue is representative of - the device to which the print spooler delivers print jobs. - </p></div><div class="sect3" title="Implementation"><div class="titlepage"><div><div><h4 class="title"><a name="id324064"></a>Implementation</h4></div></div></div><p> - It is assumed that the server is fully installed and ready for configuration of - Samba 3.0.20 and for necessary support files.

There are nine permanent - computer users. The network clients were upgraded two years ago. All computers run Windows 2000 - Professional. This year the server will be upgraded from an old Windows NT4 server (actually - running Windows NT4 Workstation, which worked fine for fewer than 10 users) that has - run in workgroup (standalone) mode, to a new Linux server running Samba. - </p><p> - The office does not want a Domain Server. Mr. Alan Meany wants to keep the Windows 2000 Professional - clients running as workgroup machines so that any staff member can take a machine home and keep - working. It has worked well so far, and your task is to replace the old server. All users have - their own workstation logon (you configured it that way when the machines were installed). - Mr. Meany wants the new system to operate the same way as the old Windows NT4 server users - cannot access each others' files, but he can access everyone's files. Each person's work files are - in a separate share on the server. Users log on to their Windows workstation with their username - and enter an assigned password; they do not need to enter a password when accessing their files - on the server. - </p><p> - <a class="indexterm" name="id325783"></a> - The new server will run Red Hat Fedora Core2. You should install Samba-3.0.20 and - copy all files from the old system to the new one. The existing Windows NT4 server has a parallel - port HP LaserJet 4 printer that is shared by all. The printer driver is installed on each - workstation. You must not change anything on the workstations. Mr. Meany gave instructions to - replace the server, <span class="quote">“<span class="quote">but leave everything else alone to avoid staff unrest.</span>”</span> - </p><p> - You have tried to educate Mr. Meany and found that he has no desire to understand networking. - He believes that Windows for Workgroups 3.11 was <span class="quote">“<span class="quote">the best server Microsoft ever sold - </span>”</span> and that Windows NT and 2000 are <span class="quote">“<span class="quote">too fang-dangled complex!</span>”</span> - </p><div class="sect3" title="Dissection and Discussion"><div class="titlepage"><div><div><h4 class="title"><a name="id325807"></a>Dissection and Discussion</h4></div></div></div><p> - <a class="indexterm" name="id325814"></a> - The requirements of this network installation are not unusual. The staff are not interested in the - details of networking. Passwords are never changed. In this example solution, we demonstrate the use - of User Mode security in a simple context. Directories should be set SGID to ensure that members - of a common group can access the contents. Each user has his or her own share to which only they - can connect. Mr. Meany's share will be a top-level directory above the share point for each employee. - Mr. Meany is a member of the same group as his staff and can access their work files. - The well-used HP LaserJet 4 is available as a service called <code class="constant">hplj</code>. - </p><p> - You have finished configuring the new hardware and have just completed installation of Red Hat - Fedora Core2.

CUPS includes an image file RIP that supports printing of image files to - non-PostScript printers.

Its complexity can be eliminated or turbocharged to suit - any fancy. - </p><p> - The LPRng software is an enhanced, extended, and portable implementation of the Berkeley LPR print - spooler functionality.

LPRng is generally preferred by those who are familiar with Berkeley lpr/lpd. - </p><p> - Which spooling system is better is a matter of personal taste.

No-Frills Samba Servers">“No-Frills Samba Servers”</a> focused on the basics of simple yet effective - network solutions. Network administrators who take pride in their work - (that's most of us, right?) take care to deliver what our users want, - but not too much more. If we make things too complex, we confound our users - and increase costs of network ownership. A professional network manager - avoids the temptation to put too much pizazz into the way that the network - operates. Some creativity is helpful, but keep it under control - good advice that the following two scenarios illustrate. - </p><p> - <a class="indexterm" name="id327280"></a> - In one case the network administrator of a mid-sized company spent three - months building a new network to replace an old Netware server. What he - delivered had all the bells and whistles he could muster. There were a - few teething problems during the changeover, nothing serious but a little - disruptive all the same. Users were exposed to many changes at once. The - network administrator was asked to resign two months after implementing - the new system because so many staff complained they had lost time and - were not happy with the new network. Everything was automated, and he - delivered more features than any advanced user could think of. He was - just too smart for his own good. - </p><p> - In the case of the other company, a new network manager was appointed - to oversee the replacement of a LanTastic network with an MS Windows - NT 4.0 network. He had the replacement installed and operational within - two weeks. Before installation and changeover, he called a meeting to - explain to all users what was going to happen, how it would affect them, - and that he would be available 24 hours a day to help them transition. - One week after conversion, he held another meeting asking for cooperation - in the introduction of a few new features that would help to make life - easier. Network users were thrilled with the help he provided. The network - he implemented was nowhere near as complex as in the first example, had fewer - features, and yet he had happy users. Months later he was still adding - new innovations. He always asked the users if a - particular feature was what they wanted. He asked his boss for a raise - and got it. He often told me, <span class="quote">“<span class="quote">Always keep a few new tricks up your - sleeves for when you need them.</span>”</span> Was he smart? You decide.

You found damaged and unusable software on - some of the workstations that came with the acquired business and found some machines in need of both - hardware and software maintenance. - </p><div class="sect2" title="Assignment Tasks"><div class="titlepage"><div><div><h3 class="title"><a name="id327326"></a>Assignment Tasks</h3></div></div></div><p> - <a class="indexterm" name="id327333"></a> - Mr. Meany is retiring in 12 months. Before he goes, he wants you to help ensure - that the business is running efficiently. Many of the new staff want notebook - computers. They visit customer business premises and need to use local network - facilities; these users are technically competent. The company uses a - business application that requires Windows XP Professional. In short, a complete - client upgrade is about to happen. Mr. Meany told you that he is working - on another business acquisition and that by the time he retires there will be - 80 to 100 users. - </p><p> - Mr. Meany is not concerned about security. He wants to make it easier for - staff to do their work. He has hired you to help him appoint a full-time - network manager before he retires. Above all, he says he is investing in - the ability to grow. He is determined to live his lifelong dream and - hand the business over to a bright and capable executive who can make - things happen. This means your network design must cope well with - growth. - </p><p> - In a few months, Abmas will require an Internet connection for email and so - that staff can easily obtain software updates. Mr. Meany is warming up to - the installation of antivirus software but is not yet ready to approve - this expense. He told you to spend the money a virus scanner costs - on better quality notebook computers for mobile users. - </p><p> - One of Mr. Meany's golfing partners convinced him to buy new laser - printers, one black only, the other a color laser printer. Staff support - the need for a color printer so they can present more attractive proposals - and reports. - </p><p> - Mr. Meany also asked if it would be possible for one of the staff to manage - user accounts from the Windows desktop. That person will be responsible for - basic operations. - </p></div></div><div class="sect1" title="Dissection and Discussion"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id327371"></a>Dissection and Discussion</h2></div></div></div><p> - What are the key requirements in this business example?

This time, the name of the server will be <code class="constant">SLEETH</code>. - </p><p> - All printers will be configured as DHCP clients. The DHCP server will assign - the printer a fixed IP address by way of its Ethernet interface (MAC) address. - See <a class="link" href="small.html#dhcp01" title="Example 2.2.

This is deliberate so that in the next chapter it is - possible to start with the installation that you have created here, migrate it - to a Samba-3 configuration, and then secure the system further. Configurations following - this one utilize features that may not be supported in Samba-2.2.x releases. - However, you should note that the examples in each chapter start with the assumption - that a fresh new installation is being effected. - </p></div><p> - Later on, when the Internet connection is implemented, you will add DNS as well as - other enhancements. It is important that you plan accordingly. - </p><p> - <a class="indexterm" name="id327498"></a> - You have split the network into two separate areas. Each has its own Ethernet switch. - There are 20 users on the accounting network and 32 users on the financial services - network. The server has two network interfaces, one serving each network. The - network printers will be located in a central area. You plan to install the new - printers and keep the old printer in use also. - </p><p> - You will provide separate file storage areas for each business entity. The old system - will go away, accounting files will be handled under a single directory, and files will - be stored under customer name, not under a personal work area. Staff will be made - responsible for file location, so the old share point must be maintained. - </p><p> - Given that DNS will not be used, you will configure WINS name resolution for UNIX - hostname name resolution. - </p><p> - <a class="indexterm" name="id327521"></a> - <a class="indexterm" name="id327530"></a> - It is necessary to map Windows Domain Groups to UNIX groups. It is - advisable to also map Windows Local Groups to UNIX groups. Additionally, the two - key staff groups in the firm are accounting staff and financial services staff. - For these, it is necessary to create UNIX groups as well as Windows Domain Groups. - </p><p> - In the sample <code class="filename">smb.conf</code> file, you have configured Samba to call the UNIX - <code class="literal">groupadd</code> to add group entries. This utility does not permit - the addition of group names that contain uppercase characters or spaces. This - is considered a bug. The <code class="literal">groupadd</code> is part of the - <code class="literal">shadow-utils</code> open source software package. A later release - of this package may have been patched to resolve this bug. If your operating - platform has this bug, it means that attempts to add a Windows Domain Group that - has either a space or uppercase characters in it will fail. See - <span class="emphasis"><em>TOSHARG2</em></span>, Chapter 11, Section 11.3.1, Example 11.1, for - more information. - </p><p> - <a class="indexterm" name="id327576"></a> - Vendor-supplied printer drivers will be installed on each client.

The decision to treat this case, as with - future examples, as a new installation is based on the premise that you can determine - the migration steps from the information provided in <a class="link" href="ntmigration.html" title="Chapter 9. Migrating NT4 Domain to Samba-3">“Migrating NT4 Domain to Samba-3”</a>. - Additionally, a fresh installation makes the example easier to follow. - </p><p> - <a class="indexterm" name="id327636"></a> - Each user will be given a home directory on the UNIX system, which will be available as a private - share.

It means that notebook users can move between - the Abmas office and client offices (so long as they, too, use DHCP) without having to manually - reconfigure their machines. It also means that when they work from their home environments - either using DHCP assigned addressing or when using dial-up networking, settings such as - default routes and DNS server addresses that apply only to the Abmas office environment do - not interfere with remote operations.

The configuration you created automatically provides each client with the IP address - of your WINS server. It also configures the client to preferentially register NetBIOS names - with the WINS server, and then instructs the client to first query the WINS server when a - NetBIOS machine name needs to be resolved to an IP Address.

The allocation - is made for all accounts that connect to that domain member server, whether within its own domain or from - trusted domains. If not stored in an LDAP backend, each domain member maintains its own unique mapping database. - This means that it is almost certain that a given user who accesses two domain member servers does not have the - same UID/GID on both servers however, this is transparent to the Windows network user. This data - is stored in the <code class="filename">winbindd_idmap.tdb</code> and <code class="filename">winbindd_cache.tdb</code> files. - </p><p> - <a class="indexterm" name="id358634"></a> - The use of an LDAP backend for the Winbind IDMAP facility permits Windows domain SIDs - mappings to UIDs/GIDs to be stored centrally. The result is a consistent mapping across all domain member - servers so configured. This solves one of the major headaches for network administrators who need to copy - files between or across network file servers. - </p></div><div class="sect2" title="Political Issues"><div class="titlepage"><div><div><h3 class="title"><a name="id358646"></a>Political Issues</h3></div></div></div><p> - <a class="indexterm" name="id358654"></a> - <a class="indexterm" name="id358661"></a> - <a class="indexterm" name="id358667"></a> - <a class="indexterm" name="id358676"></a> - One of the most fierce conflicts recently being waged is resistance to the adoption of LDAP, in - particular OpenLDAP, as a replacement for UNIX NIS (previously called Yellow Pages). Let's face it, LDAP - is different and requires a new approach to the need for a better identity management solution. The more - you work with LDAP, the more its power and flexibility emerges from its dark, cavernous chasm. - </p><p> - LDAP is a most suitable solution for heterogenous environments. If you need crypto, add Kerberos. - The reason these are preferable is because they are heterogenous. Windows solutions of this sort are <span class="emphasis"><em>not</em></span> - heterogenous by design. This is fundamental it isn't religious or political. This also doesn't say that - you can't use Windows Active Directory in a heterogenous environment it can be done, it just requires - commercial integration products. But it's not what Active Directory was designed for. - </p><p> - <a class="indexterm" name="id358707"></a> - <a class="indexterm" name="id358713"></a> - A number of long-term UNIX devotees have recently commented in various communications that the Samba Team - is the first application group to almost force network administrators to use LDAP. It should be pointed - out that we resisted this for as long as we could. It is not out of laziness or malice that LDAP has - finally emerged as the preferred identity management backend for Samba. We recommend LDAP for your total - organizational directory needs. - </p></div></div><div class="sect1" title="Implementation"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id358731"></a>Implementation</h2></div></div></div><p> - <a class="indexterm" name="id358738"></a> - <a class="indexterm" name="id358748"></a> - <a class="indexterm" name="id358757"></a> - The domain member server and the domain member client are at the center of focus in this chapter. - Configuration of Samba-3 domain controller is covered in earlier chapters, so if your - interest is in domain controller configuration, you will not find that here. You will find good - oil that helps you to add domain member servers and clients. - </p><p> - <a class="indexterm" name="id358770"></a> - In practice, domain member servers and domain member workstations are very different entities, but in - terms of technology they share similar core infrastructure. A technologist would argue that servers - and workstations are identical. Many users would argue otherwise, given that in a well-disciplined - environment a workstation (client) is a device from which a user creates documents and files that - are located on servers. A workstation is frequently viewed as a disposable (easy to replace) item, - but a server is viewed as a core component of the business. - </p><p> - <a class="indexterm" name="id358787"></a> - We can look at this another way. If a workstation breaks down, one user is affected, but if a - server breaks down, hundreds of users may not be able to work. The services that a workstation - must provide are document- and file-production oriented; a server provides information storage - and is distribution oriented. - </p><p> - <a class="indexterm" name="id358800"></a> - <a class="indexterm" name="id358807"></a> - <a class="indexterm" name="id358813"></a> - <span class="emphasis"><em>Why is this important?</em></span> For starters, we must identify what - components of the operating system and its environment must be configured. Also, it is necessary - to recognize where the interdependencies between the various services to be used are. - In particular, it is important to understand the operation of each critical part of the - authentication process, the logon process, and how user identities get resolved and applied - within the operating system and applications (like Samba) that depend on this and may - actually contribute to it. - </p><p> - So, in this chapter we demonstrate how to implement the technology. It is done within a context of - what type of service need must be fulfilled. - </p><div class="sect2" title="Samba Domain with Samba Domain Member Server Using NSS LDAP"><div class="titlepage"><div><div><h3 class="title"><a name="sdcsdmldap"></a>Samba Domain with Samba Domain Member Server Using NSS LDAP</h3></div></div></div><p> - <a class="indexterm" name="id358848"></a> - <a class="indexterm" name="id358854"></a> - <a class="indexterm" name="id358861"></a> - <a class="indexterm" name="id358868"></a> - <a class="indexterm" name="id358877"></a> - <a class="indexterm" name="id358884"></a> - In this example, it is assumed that you have Samba PDC/BDC servers. This means you are using - an LDAP ldapsam backend. We are adding to the LDAP backend database (directory) - containers for use by the IDMAP facility. This makes it possible to have globally consistent - mapping of SIDs to and from UIDs and GIDs. This means that it is necessary to run - <code class="literal">winbindd</code> as part of your configuration. The primary purpose of running - <code class="literal">winbindd</code> (within this operational context) is to permit mapping of foreign - SIDs (those not originating from the the local Samba server). Foreign SIDs can come from any - domain member client or server, or from Windows clients that do not belong to a domain. Another - way to explain the necessity to run <code class="literal">winbindd</code> is that Samba can locally - resolve only accounts that belong to the security context of its own machine SID. Winbind - handles all non-local SIDs and maps them to a local UID/GID value. The UID and GID are allocated - from the parameter values set in the <code class="filename">smb.conf</code> file for the <em class="parameter"><code>idmap uid</code></em> and - <em class="parameter"><code>idmap gid</code></em> ranges. Where LDAP is used, the mappings can be stored in LDAP - so that all domain member servers can use a consistent mapping. - </p><p> - <a class="indexterm" name="id358942"></a> - <a class="indexterm" name="id358948"></a> - <a class="indexterm" name="id358955"></a> - If your installation is accessed only from clients that are members of your own domain, and all - user accounts are present in a local passdb backend then it is not necessary to run - <code class="literal">winbindd</code>. The local passdb backend can be in smbpasswd, tdbsam, or in ldapsam. - </p><p> - It is possible to use a local passdb backend with any convenient means of resolving the POSIX - user and group account information. The POSIX information is usually obtained using the - <code class="literal">getpwnam()</code> system call.

First, make certain that - the home directories exist on the domain member server; otherwise, the home directory - share is not available. The home directories could be mounted off a domain controller - using NFS or by any other suitable means. Second, the absence of the domain name in the - home directory path is indicative that identity resolution is not being done via winbind. -</p><pre class="screen"> -<code class="prompt">root# </code> getent group -... -Domain Admins:x:512:root,jht -Domain Users:x:513:bobj,stans,chrisr,maryv,jht,josephj -Domain Guests:x:514: -Accounts:x:1000: -Finances:x:1001: -PIOps:x:1002: -sammy:x:4321: -</pre><p> - <a class="indexterm" name="id359426"></a> - <a class="indexterm" name="id359433"></a> - <a class="indexterm" name="id359440"></a> - This shows that all is working as it should be. Notice that in the LDAP database - the users' primary and secondary group memberships are identical. It is not - necessary to add secondary group memberships (in the group database) if the - user is already a member via primary group membership in the password database. - When using winbind, it is in fact undesirable to do this because it results in - doubling up of group memberships and may cause problems with winbind under certain - conditions. It is intended that these limitations with winbind will be resolved soon - after Samba-3.0.20 has been released. - </p></li><li class="step" title="Step 5"><p> - <a class="indexterm" name="id359458"></a> - The LDAP directory must have a container object for IDMAP data. There are several ways you can - check that your LDAP database is able to receive IDMAP information. One of the simplest is to - execute: -</p><pre class="screen"> -<code class="prompt">root# </code> slapcat | grep -i idmap -dn: ou=Idmap,dc=abmas,dc=biz -ou: idmap -</pre><p> - <a class="indexterm" name="id359479"></a> - If the execution of this command does not return IDMAP entries, you need to create an LDIF - template file (see <a class="link" href="unixclients.html#ch9-ldifadd" title="Example 7.2. LDIF IDMAP Add-On Load File File: /etc/openldap/idmap.LDIF">“LDIF IDMAP Add-On Load File File: /etc/openldap/idmap.LDIF”</a>).

domain using Kerberos protocols. This makes it possible to operate an entire Windows network - without the need to run NetBIOS over TCP/IP and permits more secure networking in general. An - exhaustively complete discussion of the protocols is not possible in this book; perhaps a - later book may explore the intricacies of the NetBIOS-less operation that Samba-3 can participate - in. For now, we simply focus on how a Samba-3 server can be made a domain member server. - </p><p> - <a class="indexterm" name="id361725"></a> - <a class="indexterm" name="id361732"></a> - <a class="indexterm" name="id361738"></a> - <a class="indexterm" name="id361745"></a> - The diagram in <a class="link" href="unixclients.html#ch9-adsdc" title="Figure 7.3. Active Directory Domain: Samba Member Server">“Active Directory Domain: Samba Member Server”</a> demonstrates how Samba-3 interfaces with - Microsoft Active Directory components. It should be noted that if Microsoft Windows Services - for UNIX (SFU) has been installed and correctly configured, it is possible to use client LDAP - for identity resolution just as can be done with Samba-3 when using an LDAP passdb backend. - The UNIX tool that you need for this, as in the case of LDAP on UNIX/Linux, is the PADL - Software nss_ldap tool-set. Compared with use of winbind and Kerberos, the use of - LDAP-based identity resolution is a little less secure. In view of the fact that this solution - requires additional software to be installed on the Windows 200x ADS domain controllers, - and that means more management overhead, it is likely that most Samba-3 ADS client sites - may elect to use winbind. - </p><p> - Do not attempt to use this procedure if you are not 100 percent certain that the build of Samba-3 - you are using has been compiled and linked with all the tools necessary for this to work. - Given the importance of this step, you must first validate that the Samba-3 message block - daemon (<code class="literal">smbd</code>) has the necessary features. - </p><p> - The hypothetical domain you are using in this example assumes that the Abmas London office - decided to take its own lead (some would say this is a typical behavior in a global - corporate world; besides, a little divergence and conflict makes for an interesting life). - The Windows Server 2003 ADS domain is called <code class="constant">london.abmas.biz</code> and the - name of the server is <code class="constant">W2K3S</code>. In ADS realm terms, the domain controller - is known as <code class="constant">w2k3s.london.abmas.biz</code>. In NetBIOS nomenclature, the - domain name is <code class="constant">LONDON</code> and the server name is <code class="constant">W2K3S</code>. - </p><div class="figure"><a name="ch9-adsdc"></a><p class="title"><b>Figure 7.3.

This means that the basic steps include those - outlined above with the addition of PAM configuration. Given that most workstations (desktop/client) - usually do not need to provide file and print services to a group of users, the configuration - of shares and printers is generally less important. Often this allows the share specifications - to be entirely removed from the <code class="filename">smb.conf</code> file.

The term <code class="constant">upgrade</code> refers to - the installation of a version of Samba that is a whole generation or more ahead of - that which is installed. Generations are indicated by the first digit of the version - number. So far Samba has been released in generations 1.x, 2.x, 3.x, and currently 4.0 - is in development. - </p><p> - <a class="indexterm" name="id366254"></a> - The term <code class="constant">update</code> refers to a minor version number installation - in place of one of the same generation. For example, updating from Samba 3.0.10 to 3.0.14 - is an update. The move from Samba 2.0.7 to 3.0.14 is an upgrade. - </p><p> - <a class="indexterm" name="id366269"></a> - While the use of these terms is an exercise in semantics, what needs to be realized - is that there are major functional differences between a Samba 2.x release and a Samba - 3.0.x release. Such differences may require a significantly different approach to - solving the same networking challenge and generally require careful review of the - latest documentation to identify precisely how the new installation may need to be - modified to preserve prior functionality. - </p><p> - There is an old axiom that says, <span class="quote">“<span class="quote">The greater the volume of the documentation, - the greater the risk that noone will read it, but where there is no documentation, - noone can read it!</span>”</span> While true, some documentation is an evil necessity. - It is hoped that this update to the documentation will avoid both extremes. - </p><div class="sect3" title="Security Identifiers (SIDs)"><div class="titlepage"><div><div><h4 class="title"><a name="id366291"></a>Security Identifiers (SIDs)</h4></div></div></div><p> - <a class="indexterm" name="id366298"></a> - <a class="indexterm" name="id366308"></a> - <a class="indexterm" name="id366315"></a> - <a class="indexterm" name="id366322"></a> - <a class="indexterm" name="id366328"></a> - <a class="indexterm" name="id366337"></a> - Before the days of Windows NT and OS/2, every Windows and DOS networking client - that used the SMB protocols was an entirely autonomous entity.

Samba 3.0 - rejects the connection as NT_STATUS_LOGON_FAILURE. There is no - current work around to re-establish the 2.2 behavior. - - 2) When adding machines to a Samba 2.2 controlled domain, the - 'add user script' was used to create the UNIX identity of the - machine trust account. Samba 3.0 introduces a new 'add machine - script' that must be specified for this purpose. Samba 3.0 will - not fall back to using the 'add user script' in the absence of - an 'add machine script' - -###################################################################### -Passdb Backends and Authentication -################################## - -There have been a few new changes that Samba administrators should be -aware of when moving to Samba 3.0. - - 1) encrypted passwords have been enabled by default in order to - inter-operate better with out-of-the-box Windows client - installations. This does mean that either (a) a samba account - must be created for each user, or (b) 'encrypt passwords = no' - must be explicitly defined in smb.conf. - - 2) Inclusion of new 'security = ads' option for integration - with an Active Directory domain using the native Windows - Kerberos 5 and LDAP protocols. - - MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption - type which is necessary for servers on which the - administrator password has not been changed, or kerberos-enabled - SMB connections to servers that require Kerberos SMB signing. - Besides this one difference, either MIT or Heimdal Kerberos - distributions are usable by Samba 3.0. - - -Samba 3.0 also includes the possibility of setting up chains -of authentication methods (auth methods) and account storage -backends (passdb backend). Please refer to the smb.conf(5) -man page for details. While both parameters assume sane default -values, it is likely that you will need to understand what the -values actually mean in order to ensure Samba operates correctly. - -The recommended passdb backends at this time are - - * smbpasswd - 2.2 compatible flat file format - * tdbsam - attribute rich database intended as an smbpasswd - replacement for stand alone servers - * ldapsam - attribute rich account storage and retrieval - backend utilizing an LDAP directory. - * ldapsam_compat - a 2.2 backward compatible LDAP account - backend - -Certain functions of the smbpasswd(8) tool have been split between the -new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8) -utility. See the respective man pages for details. - -###################################################################### -LDAP -#### - -This section outlines the new features affecting Samba / LDAP -integration. - -New Schema ----------- - -A new object class (sambaSamAccount) has been introduced to replace -the old sambaAccount. This change aids us in the renaming of -attributes to prevent clashes with attributes from other vendors. -There is a conversion script (examples/LDAP/convertSambaAccount) to -modify and LDIF file to the new schema. - -Example: - - $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif - $ convertSambaAccount --sid=<Domain SID> \ - --input=sambaAcct.ldif --output=sambaSamAcct.ldif \ - --changetype=[modify|add] - -The <DOM SID> can be obtained by running 'net getlocalsid -<DOMAINNAME>' on the Samba PDC as root. The changetype determines -the format of the generated LDIF output--either create new entries -or modify existing entries. - -The old sambaAccount schema may still be used by specifying the -"ldapsam_compat" passdb backend. However, the sambaAccount and -associated attributes have been moved to the historical section of -the schema file and must be uncommented before use if needed. -The 2.2 object class declaration for a sambaAccount has not changed -in the 3.0 samba.schema file. - -Other new object classes and their uses include: - - * sambaDomain - domain information used to allocate rids - for users and groups as necessary. The attributes are added - in 'ldap suffix' directory entry automatically if - an idmap uid/gid range has been set and the 'ldapsam' - passdb backend has been selected. - - * sambaGroupMapping - an object representing the - relationship between a posixGroup and a Windows - group/SID. These entries are stored in the 'ldap - group suffix' and managed by the 'net groupmap' command. - - * sambaUnixIdPool - created in the 'ldap idmap suffix' entry - automatically and contains the next available 'idmap uid' and - 'idmap gid' - - * sambaIdmapEntry - object storing a mapping between a - SID and a UNIX uid/gid. These objects are created by the - idmap_ldap module as needed. - - * sambaSidEntry - object representing a SID alone, as a Structural - class on which to build the sambaIdmapEntry. - - -New Suffix for Searching ------------------------- - -The following new smb.conf parameters have been added to aid in directing -certain LDAP queries when 'passdb backend = ldapsam://...' has been -specified. - - * ldap suffix - used to search for user and computer accounts - * ldap user suffix - used to store user accounts - * ldap machine suffix - used to store machine trust accounts - * ldap group suffix - location of posixGroup/sambaGroupMapping entries - * ldap idmap suffix - location of sambaIdmapEntry objects - -If an 'ldap suffix' is defined, it will be appended to all of the -remaining sub-suffix parameters. In this case, the order of the suffix -listings in smb.conf is important. Always place the 'ldap suffix' first -in the list. - -Due to a limitation in Samba's smb.conf parsing, you should not surround -the DN's with quotation marks. -</pre><p> - </p></div></div><div class="sect1" title="Updating a Samba-3 Installation"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id368184"></a>Updating a Samba-3 Installation</h2></div></div></div><p> -The key concern in this section is to deal with the changes that have been -affected in Samba-3 between the Samba-3.0.0 release and the current update. -Network administrators have expressed concerns over the steps that should be -taken to update Samba-3 versions. -</p><p> -<a class="indexterm" name="id368197"></a> -The information in <a class="link" href="upgrades.html#sbeug1" title="Location of config files">“Location of config files”</a> would not be necessary if every -person who has ever produced Samba executable (binary) files could agree on -the preferred location of the <code class="filename">smb.conf</code> file and other Samba control files. -Clearly, such agreement is further away than a pipedream. -</p><p> -<a class="indexterm" name="id368220"></a> -Vendors and packagers who produce Samba binary installable packages do not, -as a rule, use the default paths used by the Samba-Team for the location of -the binary files, the <code class="filename">smb.conf</code> file, and the Samba control files (tdb's -as well as files such as <code class="filename">secrets.tdb</code>).

They are very -nice in their place but are quite inappropriate for smbd. nmbd is -another matter, and multi-threading it would be very nice. -</p><p> -The short version is that smbd is not multithreaded, and alternative -servers that take this approach under Unix (such as Syntax, at the -time of writing) suffer tremendous performance penalties and are less -robust. nmbd is not threaded either, but this is because it is not -possible to do it while keeping code consistent and portable across 35 -or more platforms. (This drawback also applies to threading smbd.) -</p><p> -The longer versions is that there are very good reasons for not making -smbd multi-threaded. Multi-threading would actually make Samba much -slower, less scalable, less portable and much less robust. The fact -that we use a separate process for each connection is one of Samba's -biggest advantages. -</p></div><div class="sect1" title="Threading smbd"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id328848"></a>Threading smbd</h2></div></div></div><p> -A few problems that would arise from a threaded smbd are: -</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p> - It's not only to create threads instead of processes, but you - must care about all variables if they have to be thread specific - (currently they would be global). -</p></li><li class="listitem"><p> - if one thread dies (eg. a seg fault) then all threads die. We can - immediately throw robustness out the window. -</p></li><li class="listitem"><p> - many of the system calls we make are blocking. Non-blocking - equivalents of many calls are either not available or are awkward (and - slow) to use. So while we block in one thread all clients are - waiting. Imagine if one share is a slow NFS filesystem and the others - are fast, we will end up slowing all clients to the speed of NFS. -</p></li><li class="listitem"><p> - you can't run as a different uid in different threads.

Unfortunately some OSes -defeat this by restricting longjmp to calling addresses that are -shallower than the current address on the stack (apparently AIX does -this). This makes a truly portable threads library impossible. So to -support all our current platforms we would have to code nmbd both with -and without threads, and as the real aim of threads is to make the -code clearer we would not have gained anything. (it is a myth that -threads make things faster. threading is like recursion, it can make -things clear but the same thing can always be done faster by some -other method) -</p><p> -Chris tried to spec out a general design that would abstract threading -vs separate processes (vs other methods?) and make them accessible -through some general API. This doesn't work because of the data -sharing requirements of the protocol (packets in the future depending -on packets now, etc.) At least, the code would work but would be very -clumsy, and besides the fork() type model would never work on Unix. (Is there an OS that it would work on, for nmbd?) -</p><p> -A fork() is cheap, but not nearly cheap enough to do on every UDP -packet that arrives. Having a pool of processes is possible but is -nasty to program cleanly due to the enormous amount of shared data (in -complex structures) between the processes. We can't rely on each -platform having a shared memory system. -</p></div><div class="sect1" title="nbmd Design"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id328933"></a>nbmd Design</h2></div></div></div><p> -Originally Andrew used recursion to simulate a multi-threaded -environment, which use the stack enormously and made for really -confusing debugging sessions. Luke Leighton rewrote it to use a -queuing system that keeps state information on each packet. The -first version used a single structure which was used by all the -pending states. As the initialisation of this structure was -done by adding arguments, as the functionality developed, it got -pretty messy. So, it was replaced with a higher-order function -and a pointer to a user-defined memory block. This suddenly -made things much simpler: large numbers of functions could be -made static, and modularised. This is the same principle as used -in NT's kernel, and achieves the same effect as threads, but in -a single process. -</p><p> -Then Jeremy rewrote nmbd. The packet data in nmbd isn't what's on the -wire. It's a nice format that is very amenable to processing but still -keeps the idea of a distinct packet. See "struct packet_struct" in -nameserv.h. It has all the detail but none of the on-the-wire -mess. This makes it ideal for using in disk or memory-based databases -for browsing and WINS support. -</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="pt02.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="pt02.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="debug.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Part II.

Scattered -throughout the code were numerous calls which converted particular -strings to/from DOS codepages. The problem is that there was no way of -telling if a particular char* is in dos codepage or unix -codepage. This led to a nightmare of code that tried to cope with -particular cases without handlingt the general case. -</p></div><div class="sect1" title="The new functions"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id329365"></a>The new functions</h2></div></div></div><p> -The new system works like this: -</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p> - all char* strings inside Samba are "unix" strings. These are - multi-byte strings that are in the charset defined by the "unix - charset" option in smb.conf. -</p></li><li class="listitem"><p> - there is no single fixed character set for unix strings, but any - character set that is used does need the following properties: - </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p> - must not contain NULLs except for termination - </p></li><li class="listitem"><p> - must be 7-bit compatible with C strings, so that a constant - string or character in C will be byte-for-byte identical to the - equivalent string in the chosen character set. - </p></li><li class="listitem"><p> - when you uppercase or lowercase a string it does not become - longer than the original string - </p></li><li class="listitem"><p> - must be able to correctly hold all characters that your client - will throw at it - </p></li></ol></div><p> - For example, UTF-8 is fine, and most multi-byte asian character sets - are fine, but UCS2 could not be used for unix strings as they - contain nulls. - </p></li><li class="listitem"><p> - when you need to put a string into a buffer that will be sent on the - wire, or you need a string in a character set format that is - compatible with the clients character set then you need to use a - pull_ or push_ function. The pull_ functions pull a string from a - wire buffer into a (multi-byte) unix string. The push_ functions - push a string out to a wire buffer. -</p></li><li class="listitem"><p> - the two main pull_ and push_ functions you need to understand are - pull_string and push_string. These functions take a base pointer - that should point at the start of the SMB packet that the string is - in. The functions will check the flags field in this packet to - automatically determine if the packet is marked as a unicode packet, - and they will choose whether to use unicode for this string based on - that flag. You may also force this decision using the STR_UNICODE or - STR_ASCII flags. For use in smbd/ and libsmb/ there are wrapper - functions clistr_ and srvstr_ that call the pull_/push_ functions - with the appropriate first argument. - </p><p> - You may also call the pull_ascii/pull_ucs2 or push_ascii/push_ucs2 - functions if you know that a particular string is ascii or - unicode. There are also a number of other convenience functions in - charcnv.c that call the pull_/push_ functions with particularly - common arguments, such as pull_ascii_pstring() - </p></li><li class="listitem"><p> - The biggest thing to remember is that internal (unix) strings in Samba - may now contain multi-byte characters. This means you cannot assume - that characters are always 1 byte long. Often this means that you will - have to convert strings to ucs2 and back again in order to do some - (seemingly) simple task. For examples of how to do this see functions - like strchr_m(). I know this is very slow, and we will eventually - speed it up but right now we want this stuff correct not fast. -</p></li><li class="listitem"><p> - all lp_ functions now return unix strings. The magic "DOS" flag on - parameters is gone. -</p></li><li class="listitem"><p> - all vfs functions take unix strings. Don't convert when passing to them -</p></li></ol></div></div><div class="sect1" title="Macros in byteorder.h"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id329469"></a>Macros in byteorder.h</h2></div></div></div><p> -This section describes the macros defined in byteorder.h.

The first UINT16 setup parameter must be either -0x0026 to indicate an RPC, or 0x0001 to indicate Set Named Pipe Handle -state. The second UINT16 parameter must be the file handle for the pipe, -obtained above. -</p><p> -The Data section for an API Command of 0x0026 (RPC pipe) in the Trans -Request is the RPC Header, followed by the RPC Data.

You should read it carefully, especially - the part about security and the "PROS and CONS" section.</p></div><div class="sect1" title="How does it work?"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id332287"></a>How does it work?</h2></div></div></div><p>LanManager encryption is somewhat similar to UNIX - password encryption. The server uses a file containing a - hashed value of a user's password. This is created by taking - the user's plaintext password, capitalising it, and either - truncating to 14 bytes or padding to 14 bytes with null bytes. - This 14 byte value is used as two 56 bit DES keys to encrypt - a 'magic' eight byte value, forming a 16 byte value which is - stored by the server and client. Let this value be known as - the "hashed password".</p><p>Windows NT encryption is a higher quality mechanism, - consisting of doing an MD4 hash on a Unicode version of the user's - password. This also produces a 16 byte hash value that is - non-reversible.</p><p>When a client (LanManager, Windows for WorkGroups, Windows - 95 or Windows NT) wishes to mount a Samba drive (or use a Samba - resource), it first requests a connection and negotiates the - protocol that the client and server will use. In the reply to this - request the Samba server generates and appends an 8 byte, random - value - this is stored in the Samba server after the reply is sent - and is known as the "challenge". The challenge is different for - every client connection.</p><p>The client then uses the hashed password (16 byte values - described above), appended with 5 null bytes, as three 56 bit - DES keys, each of which is used to encrypt the challenge 8 byte - value, forming a 24 byte value known as the "response".</p><p>In the SMB call SMBsessionsetupX (when user level security - is selected) or the call SMBtconX (when share level security is - selected), the 24 byte response is returned by the client to the - Samba server. For Windows NT protocol levels the above calculation - is done on both hashes of the user's password and both responses are - returned in the SMB call, giving two 24 byte values.</p><p>The Samba server then reproduces the above calculation, using - its own stored value of the 16 byte hashed password (read from the - <code class="filename">smbpasswd</code> file - described later) and the challenge - value that it kept from the negotiate protocol reply. It then checks - to see if the 24 byte value it calculates matches the 24 byte value - returned to it from the client.</p><p>If these values match exactly, then the client knew the - correct password (or the 16 byte hashed value - see security note - below) and is thus allowed access. If not, then the client did not - know the correct password and is denied access.</p><p>Note that the Samba server never knows or stores the cleartext - of the user's password - just the 16 byte hashed values derived from - it. Also note that the cleartext password or 16 byte hashed values - are never transmitted over the network - thus increasing security.</p></div><div class="sect1" title="The smbpasswd file"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id332348"></a>The smbpasswd file</h2></div></div></div><a name="SMBPASSWDFILEFORMAT"></a><p>In order for Samba to participate in the above protocol - it must be able to look up the 16 byte hashed values given a user name. - Unfortunately, as the UNIX password value is also a one way hash - function (ie. it is impossible to retrieve the cleartext of the user's - password given the UNIX hash of it), a separate password file - containing this 16 byte value must be kept. To minimise problems with - these two password files, getting out of sync, the UNIX <code class="filename"> - /etc/passwd</code> and the <code class="filename">smbpasswd</code> file, - a utility, <code class="literal">mksmbpasswd.sh</code>, is provided to generate - a smbpasswd file from a UNIX <code class="filename">/etc/passwd</code> file. - </p><p>To generate the smbpasswd file from your <code class="filename">/etc/passwd - </code> file use the following command:</p><p><code class="prompt">$ </code><strong class="userinput"><code>cat /etc/passwd | mksmbpasswd.sh - > /usr/local/samba/private/smbpasswd</code></strong></p><p>If you are running on a system that uses NIS, use</p><p><code class="prompt">$ </code><strong class="userinput"><code>ypcat passwd | mksmbpasswd.sh - > /usr/local/samba/private/smbpasswd</code></strong></p><p>The <code class="literal">mksmbpasswd.sh</code> program is found in - the Samba source directory. By default, the smbpasswd file is - stored in :</p><p><code class="filename">/usr/local/samba/private/smbpasswd</code></p><p>The owner of the <code class="filename">/usr/local/samba/private/</code> - directory should be set to root, and the permissions on it should - be set to 0500 (<code class="literal">chmod 500 /usr/local/samba/private</code>). - </p><p>Likewise, the smbpasswd file inside the private directory should - be owned by root and the permissions on is should be set to 0600 - (<code class="literal">chmod 600 smbpasswd</code>).</p><p>The format of the smbpasswd file is (The line has been - wrapped here. It should appear as one entry per line in - your smbpasswd file.)</p><pre class="programlisting"> -username:uid:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX: - [Account type]:LCT-<last-change-time>:Long name - </pre><p>Although only the <em class="replaceable"><code>username</code></em>, - <em class="replaceable"><code>uid</code></em>, <em class="replaceable"><code> - XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</code></em>, - [<em class="replaceable"><code>Account type</code></em>] and <em class="replaceable"><code> - last-change-time</code></em> sections are significant - and are looked at in the Samba code.</p><p>It is <span class="emphasis"><em>VITALLY</em></span> important that there by 32 - 'X' characters between the two ':' characters in the XXX sections - - the smbpasswd and Samba code will fail to validate any entries that - do not have 32 characters between ':' characters. The first XXX - section is for the Lanman password hash, the second is for the - Windows NT version.</p><p>When the password file is created all users have password entries - consisting of 32 'X' characters. By default this disallows any access - as this user. When a user has a password set, the 'X' characters change - to 32 ascii hexadecimal digits (0-9, A-F). These are an ascii - representation of the 16 byte hashed value of a user's password.</p><p>To set a user to have no password (not recommended), edit the file - using vi, and replace the first 11 characters with the ascii text - <code class="constant">"NO PASSWORD"</code> (minus the quotes).</p><p>For example, to clear the password for user bob, his smbpasswd file - entry would look like :</p><pre class="programlisting"> -bob:100:NO PASSWORDXXXXXXXXXXXXXXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX: - [U ]:LCT-00000000:Bob's full name:/bobhome:/bobshell - </pre><p>If you are allowing users to use the smbpasswd command to set - their own passwords, you may want to give users NO PASSWORD initially - so they do not have to enter a previous password when changing to their - new password (not recommended). In order for you to allow this the - <code class="literal">smbpasswd</code> program must be able to connect to the - <code class="literal">smbd</code> daemon as that user with no password. Enable this - by adding the line :</p><p><code class="literal">null passwords = yes</code></p><p>to the [global] section of the smb.conf file (this is why - the above scenario is not recommended). Preferably, allocate your - users a default password to begin with, so you do not have - to enable this on your server.</p><p><span class="emphasis"><em>Note : </em></span>This file should be protected very - carefully. Anyone with access to this file can (with enough knowledge of - the protocols) gain access to your SMB server. The file is thus more - sensitive than a normal unix <code class="filename">/etc/passwd</code> file.</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="wins.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="pt03.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="pt04.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Chapter 12.

This is not for the faint of heart, but if you -are reading this then you are probably desperate. -</p><p> -Actually its not as bad as the the above makes it sound, just don't -expect the output to be very pretty :-) -</p><p> -Ok, down to business. One of the big advantages of unix systems is -that they nearly all come with a system trace utility that allows you -to monitor all system calls that a program is making. This is -extremely using for debugging and also helps when trying to work out -why something is slower than you expect. You can use system tracing -without any special compilation options. -</p><p> -The system trace utility is called different things on different -systems. On Linux systems its called strace. Under SunOS 4 its called -trace. Under SVR4 style systems (including solaris) its called -truss. Under many BSD systems its called ktrace. -</p><p> -The first thing you should do is read the man page for your native -system call tracer. In the discussion below I'll assume its called -strace as strace is the only portable system tracer (its available for -free for many unix types) and its also got some of the nicest -features. -</p><p> -Next, try using strace on some simple commands. For example, <code class="literal">strace -ls</code> or <code class="literal">strace echo hello</code>. -</p><p> -You'll notice that it produces a LOT of output. It is showing you the -arguments to every system call that the program makes and the -result. Very little happens in a program without a system call so you -get lots of output. You'll also find that it produces a lot of -"preamble" stuff showing the loading of shared libraries etc. Ignore -this (unless its going wrong!) -</p><p> -For example, the only line that really matters in the <code class="literal">strace echo -hello</code> output is: -</p><pre class="programlisting"> -write(1, "hello\n", 6) = 6 -</pre><p>all the rest is just setting up to run the program.</p><p> -Ok, now you're familiar with strace. To use it on Samba you need to -strace the running smbd daemon. The way I tend ot use it is to first -login from my Windows PC to the Samba server, then use smbstatus to -find which process ID that client is attached to, then as root I do -<code class="literal">strace -p PID</code> to attach to that process. I normally redirect the -stderr output from this command to a file for later perusal. For -example, if I'm using a csh style shell: -</p><p><code class="literal">strace -f -p 3872 >& strace.out</code></p><p>or with a sh style shell:</p><p><code class="literal">strace -f -p 3872 > strace.out 2>&1</code></p><p> -Note the "-f" option. This is only available on some systems, and -allows you to trace not just the current process, but any children it -forks. This is great for finding printing problems caused by the -"print command" being wrong. -</p><p> -Once you are attached you then can do whatever it is on the client -that is causing problems and you will capture all the system calls -that smbd makes. -</p><p> -So how do you interpret the results? Generally I search through the -output for strings that I know will appear when the problem -happens. For example, if I am having touble with permissions on a file -I would search for that files name in the strace output and look at -the surrounding lines. Another trick is to match up file descriptor -numbers and "follow" what happens to an open file until it is closed. -</p><p> -Beyond this you will have to use your initiative. To give you an idea -of what you are looking for here is a piece of strace output that -shows that <code class="filename">/dev/null</code> is not world writeable, which -causes printing to fail with Samba: -</p><pre class="programlisting"> -[pid 28268] open("/dev/null", O_RDWR) = -1 EACCES (Permission denied) -[pid 28268] open("/dev/null", O_WRONLY) = -1 EACCES (Permission denied) -</pre><p> -The process is trying to first open <code class="filename">/dev/null</code> read-write -then read-only. Both fail. This means <code class="filename">/dev/null</code> has -incorrect permissions. -</p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="pt04.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="pt04.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="devprinting.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Part IV.

They may help people who are looking at unix<->PC -interoperability. -</p><p> -It was written to help out a person who was writing a paper on unix to -PC connectivity. -</p></div><div class="sect1" title="Usernames"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id322148"></a>Usernames</h2></div></div></div><p> -The SMB protocol has only a loose username concept. Early SMB -protocols (such as CORE and COREPLUS) have no username concept at -all. Even in later protocols clients often attempt operations -(particularly printer operations) without first validating a username -on the server. -</p><p> -Unix security is based around username/password pairs. A unix box -should not allow clients to do any substantive operation without some -sort of validation. -</p><p> -The problem mostly manifests itself when the unix server is in "share -level" security mode. This is the default mode as the alternative -"user level" security mode usually forces a client to connect to the -server as the same user for each connected share, which is -inconvenient in many sites. -</p><p> -In "share level" security the client normally gives a username in the -"session setup" protocol, but does not supply an accompanying -password. The client then connects to resources using the "tree -connect" protocol, and supplies a password. The problem is that the -user on the PC types the username and the password in different -contexts, unaware that they need to go together to give access to the -server. The username is normally the one the user typed in when they -"logged onto" the PC (this assumes Windows for Workgroups). The -password is the one they chose when connecting to the disk or printer. -</p><p> -The user often chooses a totally different username for their login as -for the drive connection. Often they also want to access different -drives as different usernames. The unix server needs some way of -divining the correct username to combine with each password. -</p><p> -Samba tries to avoid this problem using several methods. These succeed -in the vast majority of cases. The methods include username maps, the -service%user syntax, the saving of session setup usernames for later -validation and the derivation of the username from the service name -(either directly or via the user= option). -</p></div><div class="sect1" title="File Ownership"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id280584"></a>File Ownership</h2></div></div></div><p> -The commonly used SMB protocols have no way of saying "you can't do -that because you don't own the file". They have, in fact, no concept -of file ownership at all. -</p><p> -This brings up all sorts of interesting problems. For example, when -you copy a file to a unix drive, and the file is world writeable but -owned by another user the file will transfer correctly but will -receive the wrong date. This is because the utime() call under unix -only succeeds for the owner of the file, or root, even if the file is -world writeable. For security reasons Samba does all file operations -as the validated user, not root, so the utime() fails. This can stuff -up shared development diectories as programs like "make" will not get -file time comparisons right. -</p><p> -There are several possible solutions to this problem, including -username mapping, and forcing a specific username for particular -shares. -</p></div><div class="sect1" title="Passwords"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id280607"></a>Passwords</h2></div></div></div><p> -Many SMB clients uppercase passwords before sending them. I have no -idea why they do this. Interestingly WfWg uppercases the password only -if the server is running a protocol greater than COREPLUS, so -obviously it isn't just the data entry routines that are to blame. -</p><p> -Unix passwords are case sensitive. So if users use mixed case -passwords they are in trouble. -</p><p> -Samba can try to cope with this by either using the "password level" -option which causes Samba to try the offered password with up to the -specified number of case changes, or by using the "password server" -option which allows Samba to do its validation via another machine -(typically a WinNT server). -</p><p> -Samba supports the password encryption method used by SMB -clients. Note that the use of password encryption in Microsoft -networking leads to password hashes that are "plain text equivalent". -This means that it is *VERY* important to ensure that the Samba -smbpasswd file containing these password hashes is only readable -by the root user. See the documentation ENCRYPTION.txt for more -details. -</p></div><div class="sect1" title="Locking"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id280636"></a>Locking</h2></div></div></div><p> -Since samba 2.2, samba supports other types of locking as well. This -section is outdated. -</p><p> -The locking calls available under a DOS/Windows environment are much -richer than those available in unix. This means a unix server (like -Samba) choosing to use the standard fcntl() based unix locking calls -to implement SMB locking has to improvise a bit. -</p><p> -One major problem is that dos locks can be in a 32 bit (unsigned) -range. Unix locking calls are 32 bits, but are signed, giving only a 31 -bit range. Unfortunately OLE2 clients use the top bit to select a -locking range used for OLE semaphores. -</p><p> -To work around this problem Samba compresses the 32 bit range into 31 -bits by appropriate bit shifting. This seems to work but is not -ideal. In a future version a separate SMB lockd may be added to cope -with the problem. -</p><p> -It also doesn't help that many unix lockd daemons are very buggy and -crash at the slightest provocation. They normally go mostly unused in -a unix environment because few unix programs use byte range -locking. The stress of huge numbers of lock requests from dos/windows -clients can kill the daemon on some systems. -</p><p> -The second major problem is the "opportunistic locking" requested by -some clients. If a client requests opportunistic locking then it is -asking the server to notify it if anyone else tries to do something on -the same file, at which time the client will say if it is willing to -give up its lock. Unix has no simple way of implementing -opportunistic locking, and currently Samba has no support for it. -</p></div><div class="sect1" title="Deny Modes"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id322351"></a>Deny Modes</h2></div></div></div><p> -When a SMB client opens a file it asks for a particular "deny mode" to -be placed on the file. These modes (DENY_NONE, DENY_READ, DENY_WRITE, -DENY_ALL, DENY_FCB and DENY_DOS) specify what actions should be -allowed by anyone else who tries to use the file at the same time. If -DENY_READ is placed on the file, for example, then any attempt to open -the file for reading should fail. -</p><p> -Unix has no equivalent notion. To implement this Samba uses either lock -files based on the files inode and placed in a separate lock -directory or a shared memory implementation. The lock file method -is clumsy and consumes processing and file resources, -the shared memory implementation is vastly prefered and is turned on -by default for those systems that support it. -</p></div><div class="sect1" title="Trapdoor UIDs"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id322374"></a>Trapdoor UIDs</h2></div></div></div><p> -A SMB session can run with several uids on the one socket. This -happens when a user connects to two shares with different -usernames. To cope with this the unix server needs to switch uids -within the one process. On some unixes (such as SCO) this is not -possible. This means that on those unixes the client is restricted to -a single uid. -</p><p> -Note that you can also get the "trapdoor uid" message for other -reasons. Please see the FAQ for details. -</p></div><div class="sect1" title="Port numbers"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id322391"></a>Port numbers</h2></div></div></div><p> -There is a convention that clients on sockets use high "unprivileged" -port numbers (>1000) and connect to servers on low "privilegedg" port -numbers. This is enforced in Unix as non-root users can't open a -socket for listening on port numbers less than 1000. -</p><p> -Most PC based SMB clients (such as WfWg and WinNT) don't follow this -convention completely. The main culprit is the netbios nameserving on -udp port 137. Name query requests come from a source port of 137. This -is a problem when you combine it with the common firewalling technique -of not allowing incoming packets on low port numbers. This means that -these clients can't query a netbios nameserver on the other side of a -low port based firewall. -</p><p> -The problem is more severe with netbios node status queries. I've -found that WfWg, Win95 and WinNT3.5 all respond to netbios node status -queries on port 137 no matter what the source port was in the -request. This works between machines that are both using port 137, but -it means it's not possible for a unix user to do a node status request -to any of these OSes unless they are running as root. The answer comes -back, but it goes to port 137 which the unix user can't listen -on. Interestingly WinNT3.1 got this right - it sends node status -responses back to the source port in the request. -</p></div><div class="sect1" title="Protocol Complexity"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id322422"></a>Protocol Complexity</h2></div></div></div><p> -There are many "protocol levels" in the SMB protocol. It seems that -each time new functionality was added to a Microsoft operating system, -they added the equivalent functions in a new protocol level of the SMB -protocol to "externalise" the new capabilities. -</p><p> -This means the protocol is very "rich", offering many ways of doing -each file operation. This means SMB servers need to be complex and -large. It also means it is very difficult to make them bug free. It is -not just Samba that suffers from this problem, other servers such as -WinNT don't support every variation of every call and it has almost -certainly been a headache for MS developers to support the myriad of -SMB calls that are available. -</p><p> -There are about 65 "top level" operations in the SMB protocol (things -like SMBread and SMBwrite). Some of these include hundreds of -sub-functions (SMBtrans has at least 120 sub-functions, like -DosPrintQAdd and NetSessionEnum). All of them take several options -that can change the way they work. Many take dozens of possible -"information levels" that change the structures that need to be -returned. Samba supports all but 2 of the "top level" functions. It -supports only 8 (so far) of the SMBtrans sub-functions. Even NT -doesn't support them all. -</p><p> -Samba currently supports up to the "NT LM 0.12" protocol, which is the -one preferred by Win95 and WinNT3.5. Luckily this protocol level has a -"capabilities" field which specifies which super-duper new-fangled -options the server supports. This helps to make the implementation of -this protocol level much easier. -</p><p> -There is also a problem with the SMB specications. SMB is a X/Open -spec, but the X/Open book is far from ideal, and fails to cover many -important issues, leaving much to the imagination. Microsoft recently -renamed the SMB protocol CIFS (Common Internet File System) and have -published new specifications. These are far superior to the old -X/Open documents but there are still undocumented calls and features. -This specification is actively being worked on by a CIFS developers -mailing list hosted by Microsft. -</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="pt01.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="pt01.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ntdomain.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Part I.

Since Samba 2.2 all file-system related operations go through -an abstraction layer for virtual file system (VFS) that is modelled -after both POSIX and additional functions needed to transform NTFS -semantics. -</p><p> -This abstraction layer now provides more features than a regular POSIX -file system could fill in. It is not required that all of them should -be implemented by your particular file system. However, when those -features are available, Samba would advertize them to a CIFS client -and they might be used by an application and in case of Windows client -that might mean a client expects even more additional functionality -when it encounters those features.

Users - who access a Samba server will do so as a particular MS Windows user. - This information is passed to the Samba server as part of the logon or - connection setup process. Samba uses this user identity to validate - whether or not the user should be given access to file system resources - (files and directories).

First we consider what the most significant differences are, then we look -at how Samba helps to bridge the differences. -</p><div class="sect2" title="MS Windows NTFS Comparison with UNIX File Systems"><div class="titlepage"><div><div><h3 class="title"><a name="id378699"></a>MS Windows NTFS Comparison with UNIX File Systems</h3></div></div></div><p> - <a class="indexterm" name="id378707"></a> - <a class="indexterm" name="id378714"></a> - <a class="indexterm" name="id378720"></a> - <a class="indexterm" name="id378730"></a> - Samba operates on top of the UNIX file system. This means it is subject to UNIX file system conventions - and permissions. It also means that if the MS Windows networking environment requires file system - behavior, that differs from UNIX file system behavior then somehow Samba is responsible for emulating - that in a transparent and consistent manner. - </p><p> - It is good news that Samba does this to a large extent, and on top of that, provides a high degree - of optional configuration to override the default behavior. We look at some of these overrides, - but for the greater part we stay within the bounds of default behavior. Those wishing to explore - the depths of control ability should review the <code class="filename">smb.conf</code> man page. - </p><p>The following compares file system features for UNIX with those of MS Windows NT/200x: - <a class="indexterm" name="id378761"></a> - - </p><div class="variablelist"><dl><dt><span class="term">Name Space</span></dt><dd><p> - MS Windows NT4/200x/XP file names may be up to 254 characters long, and UNIX file names - may be 1023 characters long. In MS Windows, file extensions indicate particular file types; - in UNIX this is not so rigorously observed because all names are considered arbitrary. - </p><p> - What MS Windows calls a folder, UNIX calls a directory. - </p></dd><dt><span class="term">Case Sensitivity</span></dt><dd><p> - <a class="indexterm" name="id378803"></a> - <a class="indexterm" name="id378810"></a> - MS Windows file names are generally uppercase if made up of 8.3 (8-character file name - and 3 character extension. File names that are longer than 8.3 are case preserving and case - insensitive. - </p><p> - UNIX file and directory names are case sensitive and case preserving. Samba implements the - MS Windows file name behavior, but it does so as a user application. The UNIX file system - provides no mechanism to perform case-insensitive file name lookups. MS Windows does this - by default. This means that Samba has to carry the processing overhead to provide features - that are not native to the UNIX operating system environment. - </p><p> - Consider the following. All are unique UNIX names but one single MS Windows file name: - </p><pre class="screen"> - MYFILE.TXT - MyFile.txt - myfile.txt - </pre><p> - So clearly, in an MS Windows file namespace these three files cannot co-exist, but in UNIX - they can. - </p><p> - So what should Samba do if all three are present? That which is lexically first will be - accessible to MS Windows users; the others are invisible and unaccessible any - other solution would be suicidal. The Windows client will ask for a case-insensitive file - lookup, and that is the reason for which Samba must offer a consistent selection in the - event that the UNIX directory contains multiple files that would match a case insensitive - file listing. - </p></dd><dt><span class="term">Directory Separators</span></dt><dd><p> - <a class="indexterm" name="id378863"></a> - MS Windows and DOS use the backslash <code class="constant">\</code> as a directory delimiter, and UNIX uses - the forward-slash <code class="constant">/</code> as its directory delimiter. This is handled transparently by Samba. - </p></dd><dt><span class="term">Drive Identification</span></dt><dd><p> - <a class="indexterm" name="id378888"></a> - MS Windows products support a notion of drive letters, like <code class="literal">C:</code>, to represent - disk partitions. UNIX has no concept of separate identifiers for file partitions; each - such file system is mounted to become part of the overall directory tree. - The UNIX directory tree begins at <code class="constant">/</code> just as the root of a DOS drive is specified as - <code class="constant">C:\</code>. - </p></dd><dt><span class="term">File Naming Conventions</span></dt><dd><p> - <a class="indexterm" name="id378922"></a> - MS Windows generally never experiences file names that begin with a dot (<code class="constant">.</code>), while in UNIX these - are commonly found in a user's home directory. Files that begin with a dot (<code class="constant">.</code>) are typically - startup files for various UNIX applications, or they may be files that contain - startup configuration data. - </p></dd><dt><span class="term">Links and Short-Cuts</span></dt><dd><p> - <a class="indexterm" name="id378949"></a> - <a class="indexterm" name="id378958"></a> - <a class="indexterm" name="id378967"></a> - MS Windows make use of <span class="emphasis"><em>links and shortcuts</em></span> that are actually special types of files that will - redirect an attempt to execute the file to the real location of the file. UNIX knows of file and directory - links, but they are entirely different from what MS Windows users are used to. - </p><p> - Symbolic links are files in UNIX that contain the actual location of the data (file or directory). An - operation (like read or write) will operate directly on the file referenced. Symbolic links are also - referred to as <span class="quote">“<span class="quote">soft links.</span>”</span> A hard link is something that MS Windows is not familiar with.

It is possible to set an ACL on a Windows file that permits the file to be written to - but not deleted. Such concepts are foreign to the UNIX operating system file space. Within the UNIX file system - anyone who has the ability to create a file can write to it. Anyone who has write permission on the - directory that contains a file and has write permission for it has the capability to delete it. - </p><p> -<a class="indexterm" name="id379532"></a> -<a class="indexterm" name="id379539"></a> -<a class="indexterm" name="id379546"></a> - For the record, in the UNIX environment the ability to delete a file is controlled by the permissions on - the directory that the file is in. In other words, a user can delete a file in a directory to which that - user has write access, even if that user does not own the file. - </p><p> -<a class="indexterm" name="id379558"></a> -<a class="indexterm" name="id379565"></a> -<a class="indexterm" name="id379572"></a> -<a class="indexterm" name="id379579"></a> - Of necessity, Samba is subject to the file system semantics of the host operating system. Samba is therefore - limited in the file system capabilities that can be made available through Windows ACLs, and therefore performs - a "best fit" translation to POSIX ACLs. Some UNIX file systems do, however support, a feature known - as extended attributes. Only the Windows concept of <span class="emphasis"><em>inheritance</em></span> is implemented by Samba through - the appropriate extended attribute. - </p><p> -<a class="indexterm" name="id379600"></a> -<a class="indexterm" name="id379606"></a> -<a class="indexterm" name="id379613"></a> -<a class="indexterm" name="id379620"></a> - The specific semantics of the extended attributes are not consistent across UNIX and UNIX-like systems such as Linux. - For example, it is possible on some implementations of the extended attributes to set a flag that prevents the directory - or file from being deleted. The extended attribute that may achieve this is called the <code class="constant">immutable</code> bit. - Unfortunately, the implementation of the immutable flag is NOT consistent with published documentation. For example, the - man page for the <code class="literal">chattr</code> on SUSE Linux 9.2 says: -</p><pre class="screen"> -A file with the i attribute cannot be modified: it cannot be deleted -or renamed, no link can be created to this file and no data can be -written to the file. Only the superuser or a process possessing the -CAP_LINUX_IMMUTABLE capability can set or clear this attribute. -</pre><p> - A simple test can be done to check if the immutable flag is supported on files in the file system of the Samba host - server. - </p><div class="procedure" title="Procedure 16.1.

However, there are limitations that a user needs to be aware of, - and also interactions with the standard Samba permission masks and mapping of DOS attributes that also need to - be taken into account. - </p><p> - If the parameter <a class="link" href="smb.conf.5.html#NTACLSUPPORT" target="_top">nt acl support</a> is set to <code class="constant">false</code>, any attempt to - set security permissions will fail with an <span class="errorname">"Access Denied" </span> message. - </p><p> - The first thing to note is that the <span class="guibutton">Add</span> button will not return a list of users in Samba - (it will give an error message saying <span class="errorname">"The remote procedure call failed and did not - execute"</span>). This means that you can only manipulate the current user/group/world permissions listed - in the dialog box. This actually works quite well because these are the only permissions that UNIX actually - has. - </p><p> - If a permission triplet (either user, group, or world) is removed from the list of permissions in the NT - dialog box, then when the <span class="guibutton">OK</span> button is pressed, it will be applied as <span class="emphasis"><em>no - permissions</em></span> on the UNIX side. If you view the permissions again, the <span class="emphasis"><em>no - permissions</em></span> entry will appear as the NT <code class="literal">O</code> flag, as described above. This allows - you to add permissions back to a file or directory once you have removed them from a triplet component. - </p><p> - Because UNIX supports only the <span class="quote">“<span class="quote">r</span>”</span>, <span class="quote">“<span class="quote">w</span>”</span>, and <span class="quote">“<span class="quote">x</span>”</span> bits of an NT ACL, if - other NT security attributes such as <code class="constant">Delete Access</code> are selected, they will be ignored - when applied on the Samba server. - </p><p> - When setting permissions on a directory, the second set of permissions (in the second set of parentheses) is - by default applied to all files within that directory.

Word then closes the old document and deletes it, then renames the new document to the original document name. - There is no mechanism by which Samba can in any way know that the new document really should be owned by the owners - of the original file. Samba has no way of knowing that the file will be renamed by MS Word. As far as Samba is able - to tell, the file that gets created is a new file, not one that the application (Word) is updating. - </p><p> - There is a workaround to solve the permissions problem. It involves understanding how you can manage file - system behavior from within the <code class="filename">smb.conf</code> file, as well as understanding how UNIX file systems work. Set on the directory - in which you are changing Word documents: <code class="literal">chmod g+s `directory_name'.</code> This ensures that all files will - be created with the group that owns the directory.

name="id398815"></a>Features and Benefits</h3></div></div></div><p> -<a class="indexterm" name="id398823"></a> - The Common UNIX Print System (<a class="ulink" href="http://www.cups.org/" target="_top">CUPS</a>) - has become quite popular. All major Linux distributions now ship it as their default printing - system. To many, it is still a mystical tool. Mostly, it just works. People tend to regard - it as a <span class="quote">“<span class="quote">black box</span>”</span> that they do not want to look into as long as it works. But once - there is a little problem, they have trouble finding out where to start debugging it. Refer to - <a class="link" href="classicalprinting.html" title="Chapter 21. Classical Printing Support">Classical Printing</a>, which contains much information - that is also relevant to CUPS. - </p><p> -<a class="indexterm" name="id398853"></a> - CUPS sports quite a few unique and powerful features. While its basic functions may be grasped quite - easily, they are also new. Because it is different from other, more traditional printing systems, it is best - not to try to apply any prior knowledge about printing to this new system. Rather, try to understand CUPS from - the beginning. This documentation will lead you to a complete understanding of CUPS. Let's start with the most - basic things first. - </p></div><div class="sect2" title="Overview"><div class="titlepage"><div><div><h3 class="title"><a name="id398866"></a>Overview</h3></div></div></div><p> -<a class="indexterm" name="id398874"></a> -<a class="indexterm" name="id398881"></a> -<a class="indexterm" name="id398888"></a> -<a class="indexterm" name="id398894"></a> -<a class="indexterm" name="id398901"></a> -<a class="indexterm" name="id398911"></a> -<a class="indexterm" name="id398920"></a> -<a class="indexterm" name="id398927"></a> - CUPS is more than just a print spooling system. It is a complete printer management system that - complies with the new Internet Printing Protocol (IPP). IPP is an industry and Internet Engineering Task Force - (IETF) standard for network printing. Many of its functions can be managed remotely (or locally) via a Web - browser (giving you platform-independent access to the CUPS print server).

A file format conversion - must take place. The problem is that there is no common standard for print file formats across all - manufacturers and printer types. While PostScript (trademark held by Adobe) and, to an extent, PCL (trademark - held by Hewlett-Packard) have developed into semi-official <span class="quote">“<span class="quote">standards</span>”</span> by being the most widely - used page description languages (PDLs), there are still many manufacturers who <span class="quote">“<span class="quote">roll their own</span>”</span> - (their reasons may be unacceptable license fees for using printer-embedded PostScript interpreters, and so on). - </p></div><div class="sect2" title="Windows Drivers, GDI, and EMF"><div class="titlepage"><div><div><h3 class="title"><a name="id400715"></a>Windows Drivers, GDI, and EMF</h3></div></div></div><p> - <a class="indexterm" name="id400723"></a> - <a class="indexterm" name="id400730"></a> - <a class="indexterm" name="id400737"></a> -<a class="indexterm" name="id400743"></a> - In Windows OS, the format conversion job is done by the printer drivers.

This GDI core is used as one common unified ground for all - Windows programs to draw pictures, fonts, and documents <span class="emphasis"><em>on screen</em></span> as well as <span class="emphasis"><em>on - paper</em></span> (print). Therefore, printer driver developers can standardize on a well-defined GDI output - for their own driver input. Achieving WYSIWYG (What You See Is What You Get) is relatively easy, because the - on-screen graphic primitives, as well as the on-paper drawn objects, come from one common source. This source, - the GDI, often produces a file format called Enhanced MetaFile (EMF).

Fortunately, most use PostScript and - that at least gives some common ground. Unfortunately, there are many different levels of quality for this - PostScript. And worse, there is a huge difference (and no common root) in the way the same document is - displayed on screen and how it is presented on paper. WYSIWYG is more difficult to achieve. This goes back to - the time, decades ago, when the predecessors of X.org, designing the UNIX foundations and protocols for - graphical user interfaces, refused to take responsibility for <span class="quote">“<span class="quote">paper output</span>”</span>, as some had - demanded at the time, and restricted itself to <span class="quote">“<span class="quote">on-screen only.</span>”</span> (For some years now, the - <span class="quote">“<span class="quote">Xprint</span>”</span> project has been under development, attempting to build printing support into the X - framework, including a PostScript and a PCL driver, but it is not yet ready for prime time.) You can see this - unfavorable inheritance up to the present day by looking into the various <span class="quote">“<span class="quote">font</span>”</span> directories on - your system; there are separate ones for fonts used for X display and fonts to be used on paper. - </p><p title="Background"><b>Background. </b> - <a class="indexterm" name="id400950"></a> -<a class="indexterm" name="id400956"></a> -<a class="indexterm" name="id400963"></a> -<a class="indexterm" name="id400970"></a> -<a class="indexterm" name="id400977"></a> -<a class="indexterm" name="id400984"></a> -<a class="indexterm" name="id400990"></a> -<a class="indexterm" name="id400997"></a> -<a class="indexterm" name="id401004"></a> -<a class="indexterm" name="id401011"></a> - The PostScript programming language is an <span class="quote">“<span class="quote">invention</span>”</span> by Adobe, but its specifications have been - published extensively. Its strength lies in its powerful abilities to describe graphical objects (fonts, - shapes, patterns, lines, curves, and dots), their attributes (color, linewidth), and the way to manipulate - (scale, distort, rotate, shift) them. Because of its open specification, anybody with the skill can start - writing his or her own implementation of a PostScript interpreter and use it to display PostScript files on - screen or on paper. Most graphical output devices are based on the concept of <span class="quote">“<span class="quote">raster images</span>”</span> or - <span class="quote">“<span class="quote">pixels</span>”</span> (one notable exception is pen plotters). Of course, you can look at a PostScript file in - its textual form and you will be reading its PostScript code, the language instructions that need to be - interpreted by a rasterizer.

The reason is - that these devices have a built-in PostScript language <span class="quote">“<span class="quote">interpreter,</span>”</span> also called a raster image - processor (RIP), (which makes them more expensive than other types of printers; throw PostScript toward them, - and they will spit out your printed pages.

The outcome of these filters is always of MIME type - <em class="parameter"><code>application/postscript</code></em> (meaning that any device-specific print options are not yet - embedded into the PostScript by CUPS and that the next filter to be called is pstops). Another prefilter is - running on all supported image formats, the <em class="parameter"><code>imagetops</code></em> filter.

There is support for - custom-size media built in. There is support to switch - print options from page to page in the middle of a job. And the - best thing is that the new <code class="constant">foomatic-rip</code> works seamlessly with all - legacy spoolers too (like LPRng, BSD-LPD, PDQ, PPR, and so on), providing - for them access to use PPDs for their printing. - </p></div><div class="sect2" title="The Complete Picture"><div class="titlepage"><div><div><h3 class="title"><a name="id403933"></a>The Complete Picture</h3></div></div></div><p> - If you want to see an overview of all the filters and how they - relate to each other, the complete picture of the puzzle is at the end - of this chapter. - </p></div><div class="sect2" title="mime.convs"><div class="titlepage"><div><div><h3 class="title"><a name="id403945"></a><code class="filename">mime.convs</code></h3></div></div></div><p> - CUPS autoconstructs all possible filtering chain paths for any given - MIME type and every printer installed.

Here, they help to send device-specific commands and settings - to the RIP, which processes the job file. CUPS has extended this - scope for PPDs to cover non-PostScript printers too. This was not - difficult, because it is a standardized file format. In a way - it was logical too: CUPS handles PostScript and uses a PostScript - RIP (Ghostscript) to process the job files. The only difference is that - a PostScript printer has the RIP built-in, for other types of - printers the Ghostscript RIP runs on the host computer. - </p><p> - PPDs for a non-PostScript printer have a few lines that are unique to - CUPS.

This filter - should be served as input an <em class="parameter"><code>application/vnd.cups-raster</code></em> MIME type - file. Therefore, CUPS should autoconstruct a filtering chain, which - delivers as its last output the specified MIME type. This is then - taken as input to the specified <em class="parameter"><code>rastertoprinter</code></em> filter. After - the last filter has done its work (<em class="parameter"><code>rastertoprinter</code></em> is a Gutenprint - filter), the file should go to the backend, which sends it to the - output device. - </p><p> - CUPS by default ships only a few generic PPDs, but they are good for - several hundred printer models.

The -roots of today's Linuxprinting.org are in the first <a class="ulink" href="http://www.linuxprinting.org/foomatic2.9/howto/" target="_top">Linux Printing HOWTO</a> that he authored. As a -side-project to this document, which served many Linux users and admins to guide their first steps in this -complicated and delicate setup (to a scientist, printing is <span class="quote">“<span class="quote">applying a structured deposition of -distinct patterns of ink or toner particles on paper substrates</span>”</span>), he started to build in a little -Postgres database with information about the hardware and driver zoo that made up Linux printing of the time. -This database became the core component of today's Foomatic collection of tools and data. In the meantime, it -has moved to an XML representation of the data. -</p></div><div class="sect3" title="Foomatic's Strange Name"><div class="titlepage"><div><div><h4 class="title"><a name="id411022"></a>Foomatic's Strange Name</h4></div></div></div><p> -<a class="indexterm" name="id411030"></a> -<span class="quote">“<span class="quote">Why the funny name?</span>”</span> you ask. When it really took off, around spring 2000, CUPS was far less -popular than today, and most systems used LPD, LPRng, or even PDQ to print. CUPS shipped with a few generic -drivers (good for a few hundred different printer models). These didn't support many device-specific options. -CUPS also shipped with its own built-in rasterization filter (<em class="parameter"><code>pstoraster</code></em>, derived from -Ghostscript). On the other hand, CUPS provided brilliant support for <span class="emphasis"><em>controlling</em></span> all -printer options through standardized and well-defined PPD files. Plus, CUPS was designed to be easily -extensible. -</p><p> -Taylor already had in his database a respectable compilation of facts about many more printers and the -Ghostscript <span class="quote">“<span class="quote">drivers</span>”</span> they run with. His idea, to generate PPDs from the database information and -use them to make standard Ghostscript filters work within CUPS, proved to work very well. It also killed -several birds with one stone: -</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>It made all current and future Ghostscript filter - developments available for CUPS.</p></li><li class="listitem"><p>It made available a lot of additional printer models - to CUPS users (because often the traditional Ghostscript way of - printing was the only one available).</p></li><li class="listitem"><p>It gave all the advanced CUPS options (Web interface, - GUI driver configurations) to users wanting (or needing) to use - Ghostscript filters.</p></li></ul></div></div><div class="sect3" title="cupsomatic, pdqomatic, lpdomatic, directomatic"><div class="titlepage"><div><div><h4 class="title"><a name="id411086"></a>cupsomatic, pdqomatic, lpdomatic, directomatic</h4></div></div></div><p> -<a class="indexterm" name="id411094"></a> -<a class="indexterm" name="id411100"></a> -<a class="indexterm" name="id411107"></a> -CUPS worked through a quickly hacked-up filter script named <a class="ulink" href="http://www.linuxprinting.org/download.cgi?filename=cupsomatic&show=0" target="_top">cupsomatic</a>. cupsomatic -ran the printfile through Ghostscript, constructing automatically the rather complicated command line needed. -It just needed to be copied into the CUPS system to make it work. To configure the way cupsomatic controls the -Ghostscript rendering process, it needs a CUPS-PPD. This PPD is generated directly from the contents of the -database. For CUPS and the respective printer/filter combo, another Perl script named CUPS-O-Matic did the PPD -generation. After that was working, Taylor implemented within a few days a similar thing for two other -spoolers. Names chosen for the config-generator scripts were <a class="ulink" href="http://www.linuxprinting.org/download.cgi?filename=lpdomatic&show=0" target="_top">PDQ-O-Matic</a> (for PDQ) -and <a class="ulink" href="http://www.linuxprinting.org/download.cgi?filename=lpdomatic&show=0" target="_top">LPD-O-Matic</a> -(for you guessed it LPD); the configuration here didn't use PPDs but other -spooler-specific files. -</p><p> -From late summer of that year, <a class="ulink" href="http://www.linuxprinting.org/till/" target="_top">Till Kamppeter</a> started -to put work into the database. Kamppeter had been newly employed by <a class="ulink" href="http://www.mandrakesoft.com/" target="_top">Mandrakesoft</a> to convert its printing system over to CUPS, after -they had seen his <a class="ulink" href="http://www.fltk.org/" target="_top">FLTK</a>-based <a class="ulink" href="http://cups.sourceforge.net/xpp/" target="_top">XPP</a> (a GUI front-end to the CUPS lp-command). He added a huge -amount of new information and new printers. He also developed the support for other spoolers, like <a class="ulink" href="http://ppr.sourceforge.net/" target="_top">PPR</a> (via ppromatic), <a class="ulink" href="http://sourceforge.net/projects/lpr/" target="_top">GNUlpr</a>, and <a class="ulink" href="http://www.lprng.org/" target="_top">LPRng</a> (both via an extended lpdomatic) and spooler-less printing (<a class="ulink" href="http://www.linuxprinting.org/download.cgi?filename=directomatic&show=0" target="_top">directomatic</a>). -</p><p> -So, to answer your question, <span class="quote">“<span class="quote">Foomatic</span>”</span> is the general name for all the overlapping code and data -behind the <span class="quote">“<span class="quote">*omatic</span>”</span> scripts. Foomatic, up to versions 2.0.x, required (ugly) Perl data -structures attached to Linuxprinting.org PPDs for CUPS. It had a different <span class="quote">“<span class="quote">*omatic</span>”</span> script for -every spooler, as well as different printer configuration files. -</p></div><div class="sect3" title="The Grand Unification Achieved"><div class="titlepage"><div><div><h4 class="title"><a name="id411224"></a>The <span class="emphasis"><em>Grand Unification</em></span> Achieved</h4></div></div></div><p> -<a class="indexterm" name="id411235"></a> -This has all changed in Foomatic versions 2.9 (beta) and released as <span class="quote">“<span class="quote">stable</span>”</span> 3.0. It has now -achieved the convergence of all *omatic scripts and is called the <a class="ulink" href="http://www.linuxprinting.org/foomatic2.9/download.cgi?filename=foomatic-rip&show=0" target="_top">foomatic-rip</a>. -This single script is the unification of the previously different spooler-specific *omatic scripts. -foomatic-rip is used by all the different spoolers alike, and because it can read PPDs (both the original -PostScript printer PPDs and the Linuxprinting.org-generated ones), all of a sudden all supported spoolers can -have the power of PPDs at their disposal. Users only need to plug foomatic-rip into their system.

At the same time, it can read the PPD -associated with a print queue and modify the print job according to the user selections. Together with this -comes the 100% compliance of the new Foomatic PPDs with the Adobe spec. Some innovative features of the -Foomatic concept may surprise users. It will support custom paper sizes for many printers and will support -printing on media drawn from different paper trays within the same job (in both cases, even where there is no -support for this from Windows-based vendor printer drivers). -</p></div><div class="sect3" title="Driver Development Outside"><div class="titlepage"><div><div><h4 class="title"><a name="id411332"></a>Driver Development Outside</h4></div></div></div><p> -<a class="indexterm" name="id411340"></a> -Most driver development itself does not happen within Linuxprinting.org.

Not only does it keep the printer and driver -information, but it is organized in a way that it can generate PPD files on the fly from its internal -XML-based datasets. While these PPDs are modeled to the Adobe specification of PPDs, the -Linuxprinting.org/Foomatic-PPDs do not normally drive PostScript printers. They are used to describe all the -bells and whistles you could ring or blow on an Epson Stylus inkjet, or an HP Photosmart, or what-have-you. -The main trick is one little additional line, not envisaged by the PPD specification, starting with the -<em class="parameter"><code>*cupsFilter</code></em> keyword. It tells the CUPS daemon how to proceed with the PostScript print -file (old-style Foomatic-PPDs named the cupsomatic filter script, while the new-style PPDs are now call -foomatic-rip). This filter script calls Ghostscript on the host system (the recommended variant is ESP -Ghostscript) to do the rendering work. foomatic-rip knows which filter or internal device setting it should -ask from Ghostscript to convert the PostScript print job into a raster format ready for the target device. -This usage of PPDs to describe the options of non-PostScript printers was the invention of the CUPS -developers. The rest is easy.

For troubleshooting purposes, this is what you -should do to determine if that part of the process chain is in order. Then proceed to fix the network -connection/authentication to the Windows host, and so on. -</p><p> -To install a printer with the <em class="parameter"><code>smb</code></em> backend on CUPS, use this command: -</p><pre class="screen"> -<code class="prompt">root# </code><strong class="userinput"><code>lpadmin -p winprinter -v smb://WINDOWSNETBIOSNAME/printersharename \ - -P /path/to/PPD</code></strong> -</pre><p> -<a class="indexterm" name="id413205"></a> -<a class="indexterm" name="id413212"></a> -<a class="indexterm" name="id413218"></a> -The PPD must be able to direct CUPS to generate the print data for the target model.

This is an inherently insecure option; however, it is the only one. Don't use it -if you want to protect your passwords.

Nearly all information resources (host names) are resolved -to their Internet protocol (IP) addresses through DNS. Windows networking tried hard to avoid the -complexities of DNS, but alas, DNS won. <a class="indexterm" name="id454349"></a> The alternative to -DNS, the Windows Internet Name Service (WINS) an artifact of NetBIOS networking over the TCP/IP -protocols has demonstrated scalability problems as well as a flat, nonhierarchical namespace that -became unmanageable as the size and complexity of information technology networks grew. -</p><p> -<a class="indexterm" name="id454368"></a> -<a class="indexterm" name="id454374"></a> -WINS is a Microsoft implementation of the RFC1001/1002 NetBIOS Name Service (NBNS). -It allows NetBIOS clients (like Microsoft Windows machines) to register an arbitrary -machine name that the administrator or user has chosen together with the IP -address that the machine has been given. Through the use of WINS, network client machines -could resolve machine names to their IP address. -</p><p> -The demand for an alternative to the limitations of NetBIOS networking finally drove -Microsoft to use DNS and Active Directory. Microsoft's new implementation attempts -to use DNS in a manner similar to the way that WINS is used for NetBIOS networking. -Both WINS and Microsoft DNS rely on dynamic name registration. -</p><p> -Microsoft Windows clients can perform dynamic name registration to the DNS server -on startup. Alternatively, where DHCP is used to assign workstation IP addresses, -it is possible to register hostnames and their IP address by the DHCP server as -soon as a client acknowledges an IP address lease.

The form letter area should be read-only to - all accounting staff except the manager. The general filing system has to have a structured - layout with a general area for all staff to store general documents as well as a separate - file area for each member of her team that is private to that person, but she wants full - access to all areas.

Remember, our objective is - to create a simple but working solution. The remainder of this book should help to highlight - opportunity for greater functionality and the complexity that goes with it. - </p><p> - A domain controller configuration can be achieved with a simple configuration using the new - tdbsam password backend. This type of configuration is good for small - offices, but has limited scalability (cannot be replicated), and performance can be expected - to fall as the size and complexity of the domain increases. - </p><p> - The use of tdbsam is best limited to sites that do not need - more than a Primary Domain Controller (PDC). As the size of a domain grows the need - for additional domain controllers becomes apparent. Do not attempt to under-resource - a Microsoft Windows network environment; domain controllers provide essential - authentication services. The following are symptoms of an under-resourced domain control - environment: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - Domain logons intermittently fail. - </p></li><li class="listitem"><p> - File access on a domain member server intermittently fails, giving a permission denied - error message. - </p></li></ul></div><p> - A more scalable domain control authentication backend option might use - Microsoft Active Directory or an LDAP-based backend. Samba-3 provides - for both options as a domain member server. As a PDC, Samba-3 is not able to provide - an exact alternative to the functionality that is available with Active Directory. - Samba-3 can provide a scalable LDAP-based PDC/BDC solution. - </p><p> - The tdbsam authentication backend provides no facility to replicate - the contents of the database, except by external means (i.e., there is no self-contained protocol - in Samba-3 for Security Account Manager database [SAM] replication). - </p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> - If you need more than one domain controller, do not use a tdbsam authentication backend. - </p></div><div class="sect3" title="Example: Engineering Office"><div class="titlepage"><div><div><h4 class="title"><a name="id328866"></a>Example: Engineering Office</h4></div></div></div><p> - The engineering office network server we present here is designed to demonstrate use - of the new tdbsam password backend.

In the case of the red, white, and blue domains, with -Windows 2000 and ADS, the red and blue domains can trust each other. This is an inherent feature of ADS -domains. Samba-3 implements MS Windows NT4-style interdomain trusts and interoperates with MS Windows 200x ADS -security domains in similar manner to MS Windows NT4-style domains. -</p></div><div class="sect1" title="Native MS Windows NT4 Trusts Configuration"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id387144"></a>Native MS Windows NT4 Trusts Configuration</h2></div></div></div><p> -<a class="indexterm" name="id387152"></a> -<a class="indexterm" name="id387161"></a> -<a class="indexterm" name="id387168"></a> -There are two steps to creating an interdomain trust relationship.

This team - includes scientists, engineers, programmers, business people, and students. - </p><p> - Team members were drawn into active participation through the desire to help - deliver an exciting level of transparent interoperability between Microsoft - Windows and the non-Microsoft information - technology world. - </p><p> - The slogan that unites the efforts behind the Samba project says: - <span class="emphasis"><em>Samba, Opening Windows to a Wider World!</em></span> The goal - behind the project is one of removing barriers to interoperability. - </p><p> - Samba provides file and print services for Microsoft Windows clients. These - services may be hosted off any TCP/IP-enabled platform. The original deployment - platforms were UNIX and Linux, though today it is in common use across - a broad variety of systems. - </p><p> - The Samba project includes not only an impressive feature set in file and print - serving capabilities, but has been extended to include client functionality, - utilities to ease migration to Samba, tools to aid interoperability with - Microsoft Windows, and administration tools. - </p><p> - The real people behind Samba are users like you. You have inspired the - developers (the Samba Team) to do more than any of them imagined could or should - be done. User feedback drives Samba development. Samba-3 in particular incorporates - a huge amount of work done as a result of user requests, suggestions and direct - code contributions. - </p></div><div class="sect1" title="Why This Book?"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id280609"></a>Why This Book?</h2></div></div></div><p> - There is admittedly a large number of Samba books on the market today and - each book has its place. Despite the apparent plethora of books, Samba - as a project continues to receive much criticism for failing to provide - sufficient documentation. Samba is also criticized for being too complex - and too difficult to configure. In many ways this is evidence of the - success of Samba as there would be no complaints if it was not successful. - </p><p> - The Samba Team members work predominantly with UNIX and Linux, so - it is hardly surprising that existing Samba documentation should reflect - that orientation. The original HOWTO text documents were intended to provide - some tips, a few golden nuggets, and if they helped anyone then that was - just wonderful.

The Windows network security -domain context should be sized and scoped before implementation. Particular attention needs to be -paid to the location of the Primary Domain Controller (PDC) as well as backup controllers (BDCs). -One way in which Samba-3 differs from Microsoft technology is that if one chooses to use an LDAP -authentication backend, then the same database can be used by several different domains. In a -complex organization, there can be a single LDAP database, which itself can be distributed (have -a master server and multiple slave servers) that can simultaneously serve multiple domains. -</p><p> -<a class="indexterm" name="id441932"></a> -From a design perspective, the number of users per server as well as the number of servers per -domain should be scaled taking into consideration server capacity and network bandwidth. -</p><p> -<a class="indexterm" name="id441944"></a> -<a class="indexterm" name="id441951"></a> -<a class="indexterm" name="id441958"></a> -<a class="indexterm" name="id441964"></a> -<a class="indexterm" name="id441971"></a> -<a class="indexterm" name="id441978"></a> -A physical network segment may house several domains.

The Samba Team has introduced tools, such as -<code class="literal">smbgroupedit</code> and <code class="literal">rpcclient</code>, from which really useful capabilities have -been integrated into the <code class="literal">net</code>. The <code class="literal">smbgroupedit</code> command was absorbed -entirely into the <code class="literal">net</code>, while only some features of the <code class="literal">rpcclient</code> command -have been ported to it. Anyone who finds older references to these utilities and to the functionality they -provided should look at the <code class="literal">net</code> command before searching elsewhere. -</p><p> -A Samba-3 administrator cannot afford to gloss over this chapter because to do so will almost certainly cause -the infliction of self-induced pain, agony, and desperation.

Of course, the - creation of user and group accounts is essential for both a standalone server and a PDC. - In the case of a BDC or a Domain Member server (DMS), domain user and group accounts are obtained from - the central domain authentication backend. - </p><p> -<a class="indexterm" name="id367976"></a> -<a class="indexterm" name="id367983"></a> -<a class="indexterm" name="id367990"></a> -<a class="indexterm" name="id367996"></a> -<a class="indexterm" name="id368003"></a> -<a class="indexterm" name="id368010"></a> -<a class="indexterm" name="id368016"></a> -<a class="indexterm" name="id368023"></a> - Regardless of the type of server being installed, local UNIX groups must be mapped to the Windows - networking domain global group accounts. Do you ask why? Because Samba always limits its access to - the resources of the host server by way of traditional UNIX UID and GID controls. This means that local - groups must be mapped to domain global groups so that domain users who are members of the domain - global groups can be given access rights based on UIDs and GIDs local to the server that is hosting - Samba. Such mappings are implemented using the <code class="literal">net</code> command. - </p><p> -<a class="indexterm" name="id368043"></a> -<a class="indexterm" name="id368050"></a> -<a class="indexterm" name="id368056"></a> -<a class="indexterm" name="id368063"></a> -<a class="indexterm" name="id368070"></a> -<a class="indexterm" name="id368077"></a> -<a class="indexterm" name="id368083"></a> - UNIX systems that are hosting a Samba-3 server that is running as a member (PDC, BDC, or DMS) must have - a machine security account in the domain authentication database (or directory). The creation of such - security (or trust) accounts is also handled using the <code class="literal">net</code> command. - </p><p> -<a class="indexterm" name="id368101"></a> -<a class="indexterm" name="id368108"></a> -<a class="indexterm" name="id368115"></a> -<a class="indexterm" name="id368121"></a> -<a class="indexterm" name="id368128"></a> -<a class="indexterm" name="id368135"></a> -<a class="indexterm" name="id368142"></a> -<a class="indexterm" name="id368149"></a> -<a class="indexterm" name="id368155"></a> - The establishment of interdomain trusts is achieved using the <code class="literal">net</code> command also, as - may a plethora of typical administrative duties such as user management, group management, share and - printer management, file and printer migration, security identifier management, and so on. - </p><p> -<a class="indexterm" name="id368173"></a> -<a class="indexterm" name="id368180"></a> - The overall picture should be clear now: the <code class="literal">net</code> command plays a central role - on the Samba-3 stage. This role will continue to be developed. The inclusion of this chapter is - evidence of its importance, one that has grown in complexity to the point that it is no longer considered - prudent to cover its use fully in the online UNIX man pages. - </p></div><div class="sect1" title="Administrative Tasks and Methods"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id368198"></a>Administrative Tasks and Methods</h2></div></div></div><p> -<a class="indexterm" name="id368205"></a> -<a class="indexterm" name="id368212"></a> -<a class="indexterm" name="id368218"></a> -<a class="indexterm" name="id368228"></a> - The basic operations of the <code class="literal">net</code> command are documented here. This documentation is not - exhaustive, and thus it is incomplete. Since the primary focus is on migration from Windows servers to a Samba - server, the emphasis is on the use of the Distributed Computing Environment Remote Procedure Call (DCE RPC) - mode of operation. When used against a server that is a member of an Active Directory domain, it is preferable - (and often necessary) to use ADS mode operations. The <code class="literal">net</code> command supports both, but not - for every operation. For most operations, if the mode is not specified, <code class="literal">net</code> will - automatically fall back via the <code class="constant">ads</code>, <code class="constant">rpc</code>, and - <code class="constant">rap</code> modes. Please refer to the man page for a more comprehensive overview of the - capabilities of this utility. - </p></div><div class="sect1" title="UNIX and Windows Group Management"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id368272"></a>UNIX and Windows Group Management</h2></div></div></div><p> -<a class="indexterm" name="id368280"></a> -<a class="indexterm" name="id368286"></a> -<a class="indexterm" name="id368295"></a> -<a class="indexterm" name="id368304"></a> -<a class="indexterm" name="id368312"></a> - As stated, the focus in most of this chapter is on use of the <code class="literal">net rpc</code> family of - operations that are supported by Samba. Most of them are supported by the <code class="literal">net ads</code> - mode when used in connection with Active Directory. The <code class="literal">net rap</code> operating mode is - also supported for some of these operations.

Domain groups can contain (have as members) only domain user accounts. Local groups - can contain local users, domain users, and domain groups as members. - </p><p> - The purpose of a local group is to permit file permission to be set for a group account that, like the - usual UNIX/Linux group, is persistent across redeployment of a Windows file server. - </p><div class="sect2" title="Adding, Renaming, or Deletion of Group Accounts"><div class="titlepage"><div><div><h3 class="title"><a name="id368421"></a>Adding, Renaming, or Deletion of Group Accounts</h3></div></div></div><p> - Samba provides file and print services to Windows clients. The file system resources it makes available - to the Windows environment must, of necessity, be provided in a manner that is compatible with the - Windows networking environment. UNIX groups are created and deleted as required to serve operational - needs in the UNIX operating system and its file systems. - </p><p> - In order to make available to the Windows environment, Samba has a facility by which UNIX groups can - be mapped to a logical entity, called a Windows (or domain) group. Samba supports two types of Windows - groups, local and global. Global groups can contain as members, global users. This membership is - affected in the normal UNIX manner, but adding UNIX users to UNIX groups. Windows user accounts consist - of a mapping between a user SambaSAMAccount (logical entity) and a UNIX user account.

For example, when migrating a fileserver, file ACLs and DOS file attributes from - the Windows server can be included in the migration process and will reappear, almost identically, - on the Samba server when the migration has been completed. - </p><p> - The migration process can be completed only with the Samba server already being fully operational. - The user and group accounts must be migrated before attempting to migrate data - share, files, and printers. The migration of files and printer configurations involves the use - of both SMB and MS DCE RPC services. The benefit of the manner in which the migration process has - been implemented is that the possibility now exists to use a Samba server as a man-in-middle migration - service that affects a transfer of data from one server to another. For example, if the Samba - server is called MESSER, the source Windows NT4 server is called PEPPY, and the target Samba - server is called GONZALES, the machine MESSER can be used to effect the migration of all data - (files and shares) from PEPPY to GONZALES. If the target machine is not specified, the local - server is assumed by default - as net's general rule of thumb . - </p><p> - The success of server migration requires a firm understanding of the structure of the source - server (or domain) as well as the processes on which the migration is critically dependant. - </p><p> - There are two known limitations to the migration process: - </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p> - The <code class="literal">net</code> command requires that the user credentials provided exist on both - the migration source and the migration target. - </p></li><li class="listitem"><p> - Printer settings may not be fully or may be incorrectly migrated.

A stanza contains the parameters within which a file or print share are defined. - The use of this migration method will create share stanzas that have as parameters the file - system directory path, an optional description, and simple security settings that permit write - access to files. One of the first steps necessary following migration is to review the share - stanzas to ensure that the settings are suitable for use. - </p><p> - The shares are created on the fly as part of the migration process. The <code class="literal">smbd</code> - application does this by calling on the operating system to execute the script specified by the - <code class="filename">smb.conf</code> parameter <em class="parameter"><code>add share command</code></em>. - </p><p> - There is a suitable example script for the <em class="parameter"><code>add share command</code></em> in the - <code class="filename">$SAMBA_SOURCES/examples/scripts</code> directory. It should be noted that - the account that is used to drive the migration must, of necessity, have appropriate file system - access privileges and have the right to create shares and to set ACLs on them. Such rights are - conferred by these rights: <em class="parameter"><code>SeAddUsersPrivilege</code></em> and <em class="parameter"><code>SeDiskOperatorPrivilege</code></em>. - For more information regarding rights and privileges please refer to <a class="link" href="rights.html" title="Chapter 15. User Rights and Privileges">“User Rights and Privileges”</a>. - </p><p> - The syntax of the share migration command is shown here: -</p><pre class="screen"> -net rpc share MIGRATE SHARES <share-name> -S <source> - [--destination=localhost] [--exclude=share1,share2] [-v] -</pre><p> - When the parameter <share-name> is omitted, all shares will be migrated. The potentially - large list of available shares on the system that is being migrated can be limited using the - <em class="parameter"><code>--exclude</code></em> switch. For example: -<a class="indexterm" name="id371524"></a> -</p><pre class="screen"> -<code class="prompt">root# </code> net rpc share migrate shares myshare\ - -S win2k -U administrator%secret" -</pre><p> - This will migrate the share <code class="constant">myshare</code> from the server <code class="constant">win2k</code> - to the Samba Server using the permissions that are tied to the account <code class="constant">administrator</code> - with the password <code class="constant">secret</code>. The account that is used must be the same on both the - migration source server and the target Samba server. The use of the <code class="literal">net rpc - vampire</code>, prior to attempting the migration of shares, will ensure that accounts will be - identical on both systems. One precaution worth taking before commencement of migration of shares is - to validate that the migrated accounts (on the Samba server) have the needed rights and privileges. - This can be done as shown here: -<a class="indexterm" name="id371572"></a> -</p><pre class="screen"> -<code class="prompt">root# </code> net rpc right list accounts -Uroot%not24get -</pre><p> - The steps taken so far perform only the migration of shares.

For many people preparation is potentially boring and the real excitement only begins when file - data can be used. The next steps demonstrate the techniques that can be used to transfer (migrate) - data files using the <code class="literal">net</code> command. - </p><p> - Transfer of files from one server to another has always been a challenge for MS Windows - administrators because Windows NT and 200X servers do not always include the tools needed. The - <code class="literal">xcopy</code> from Windows NT is not capable of preserving file and directory ACLs, - it does so only with Windows 200x. Microsoft does provide a - utility that can copy ACLs (security settings) called <code class="literal">scopy</code>, but it is provided only - as part of the Windows NT or 200X Server Resource Kit. - </p><p> - There are several tools, both commercial and freeware, that can be used from a Windows server to copy files - and directories with full preservation of security settings. One of the best known of the free tools is - called <code class="literal">robocopy</code>. - </p><p> - The <code class="literal">net</code> utility can be used to copy files and directories with full preservation of - ACLs as well as DOS file attributes. Note that including ACLs makes sense only where the destination - system will operate within the same security context as the source system. This applies both to a - DMS and to domain controllers that result from a vampired domain. - Before file and directory migration, all shares must already exist. - </p><p> - The syntax for the migration commands is shown here: -</p><pre class="screen"> -net rpc share MIGRATE FILES <share-name> -S <source> - [--destination=localhost] [--exclude=share1,share2] - [--acls] [--attrs] [--timestamps] [-v] -</pre><p> - If the <share-name> parameter is omitted, all shares will be migrated. The potentially large - list of shares on the source system can be restricted using the <em class="parameter"><code>--exclude</code></em> command - switch. - </p><p> - Where it is necessary to preserve all file ACLs, the <em class="parameter"><code>--acls</code></em> switch should be added - to the above command line. Original file timestamps can be preserved by specifying the - <em class="parameter"><code>--timestamps</code></em> switch, and the DOS file attributes (i.e., hidden, archive, etc.) can - be preserved by specifying the <em class="parameter"><code>--attrs</code></em> switch. - </p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> - The ability to preserve ACLs depends on appropriate support for ACLs as well as the general file system - semantics of the host operating system on the target server. A migration from one Windows file server to - another will perfectly preserve all file attributes. Because of the difficulty of mapping Windows ACLs - onto a POSIX ACLs-supporting system, there can be no perfect migration of Windows ACLs to a Samba server. - </p></div><p> - The ACLs that result on a Samba server will most probably not match the originating ACLs. Windows supports - the possibility of files that are owned only by a group. Group-alone file ownership is not possible under - UNIX/Linux. Errors in migrating group-owned files can be avoided by using the <code class="filename">smb.conf</code> file - <a class="link" href="smb.conf.5.html#FORCEUNKNOWNACLUSER" target="_top">force unknown acl user = yes</a> parameter. This facility will - automatically convert group-owned files into correctly user-owned files on the Samba server. - </p><p> - An example for migration of files from a machine called <code class="constant">nt4box</code> to the Samba server - from which the process will be handled is shown here: -<a class="indexterm" name="id371742"></a> -</p><pre class="screen"> -<code class="prompt">root# </code> net rpc share migrate files -S nt4box --acls \ - --attrs -U administrator%secret -</pre><p> - </p><p> - This command will migrate all files and directories from all file shares on the Windows server called - <code class="constant">nt4box</code> to the Samba server from which migration is initiated. Files that are group-owned - will be owned by the user account <code class="constant">administrator</code>. - </p></div><div class="sect3" title="Share-ACL Migration"><div class="titlepage"><div><div><h4 class="title"><a name="id371779"></a>Share-ACL Migration</h4></div></div></div><p> - It is possible to have share-ACLs (security descriptors) that won't allow you, even as Administrator, to - copy any files or directories into it. Therefor the migration of the share-ACLs has been put into a separate - function: -<a class="indexterm" name="id371789"></a> -</p><pre class="screen"> -<code class="prompt">root# </code> net rpc share migrate security -S nt4box -U administrator%secret -</pre><p> - </p><p> - This command will only copy the share-ACL of each share on nt4box to your local samba-system. - </p></div><div class="sect3" title="Simultaneous Share and File Migration"><div class="titlepage"><div><div><h4 class="title"><a name="id371818"></a>Simultaneous Share and File Migration</h4></div></div></div><p> - The operating mode shown here is just a combination of the previous three.

If - the need is very simple, the best solution to the implementation of printing support may well be to - re-install everything from a clean slate instead of migrating older configurations. On the other hand, - a complex network that is integrated with many international offices and a complex arrangement of local branch - offices, each of which form an inter-twined maze of printing possibilities, the ability to migrate all - printer configurations is decidedly beneficial. To manually re-establish a complex printing network - will take much time and frustration. Often it will not be possible to find driver files that are - currently in use, necessitating the installation of newer drivers. Newer drivers often implement - printing features that will necessitate a change in the printer usage. Additionally, with very complex - printer configurations it becomes almost impossible to re-create the same environment no matter - how extensively it has been documented. - </p><p> - The migration of an existing printing architecture involves the following: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>Establishment of print queues.</p></li><li class="listitem"><p>Installation of printer drivers (both for the print server and for Windows clients.</p></li><li class="listitem"><p>Configuration of printing forms.</p></li><li class="listitem"><p>Implementation of security settings.</p></li><li class="listitem"><p>Configuration of printer settings.</p></li></ul></div><p> - The Samba <code class="literal">net</code> utility permits printer migration from one Windows print server - to another. When this tool is used to migrate printers to a Samba server <code class="literal">smbd</code>, - the application that receives the network requests to create the necessary services must call out - to the operating system in order to create the underlying printers. The call-out is implemented - by way of an interface script that can be specified by the <code class="filename">smb.conf</code> file parameter - <a class="link" href="smb.conf.5.html#ADDPRINTERSCRIPT" target="_top">add printer script</a>. This script is essential to the migration process. - A suitable example script may be obtained from the <code class="filename">$SAMBA_SOURCES/examples/scripts</code> - directory. Take note that this script must be customized to suit the operating system environment - and may use its tools to create a print queue. - </p><p> - Each of the components listed above can be completed separately, or they can be completed as part of an - automated operation. Many network administrators prefer to deal with migration issues in a manner that - gives them the most control, particularly when things go wrong.

An accurate understanding of -how Samba implements each security mode as well as how to configure MS Windows clients for each mode will -significantly reduce user complaints and administrator heartache. -</p><p> -<a class="indexterm" name="id330985"></a> -<a class="indexterm" name="id330993"></a> -Microsoft Windows networking uses a protocol that was originally called the Server Message Block (SMB) -protocol. Since some time around 1996 the protocol has been better known as the Common Internet Filesystem -(CIFS) protocol. -</p><p> -<a class="indexterm" name="id331007"></a> -<a class="indexterm" name="id331013"></a> -<a class="indexterm" name="id331019"></a> -<a class="indexterm" name="id331026"></a> -In the SMB/CIFS networking world, there are only two types of security: <span class="emphasis"><em>user-level</em></span> and -<span class="emphasis"><em>share level</em></span>. We refer to these collectively as <span class="emphasis"><em>security levels</em></span>. In -implementing these two security levels, Samba provides flexibilities that are not available with MS Windows -NT4/200x servers. In fact, Samba implements <span class="emphasis"><em>share-level</em></span> security only one way, but has -four ways of implementing <span class="emphasis"><em>user-level</em></span> security. Collectively, we call the Samba -implementations of the security levels <span class="emphasis"><em>security modes</em></span>. They are known as -<span class="emphasis"><em>share</em></span>, <span class="emphasis"><em>user</em></span>, <span class="emphasis"><em>domain</em></span>, <span class="emphasis"><em>ADS</em></span>, -and <span class="emphasis"><em>server</em></span> modes. They are documented in this chapter. -</p><p> -An SMB server informs the client, at the time of a session setup, the security level the server is running. -There are two options: share-level and user-level. Which of these two the client receives affects the way the -client then tries to authenticate itself. It does not directly affect (to any great extent) the way the Samba -server does security. This may sound strange, but it fits in with the client/server approach of SMB. In SMB -everything is initiated and controlled by the client, and the server can only tell the client what is -available and whether an action is allowed. -</p><p> -The term <code class="literal">client</code> refers to all agents whether it is a Windows workstation, a Windows server, -another Samba server, or any vanilla SMB or CIFS client application (e.g., <code class="literal">smbclient</code>) that -make use of services provided by an SMB/CIFS server. -</p><div class="sect2" title="User Level Security"><div class="titlepage"><div><div><h3 class="title"><a name="id331101"></a>User Level Security</h3></div></div></div><p> -<a class="indexterm" name="id331108"></a> -We describe user-level security first because its simpler. In user-level security, the client sends a session -setup request directly following protocol negotiation. This request provides a username and password. The -server can either accept or reject that username/password combination. At this stage the server has no idea -what share the client will eventually try to connect to, so it can't base the -<span class="emphasis"><em>accept/reject</em></span> on anything other than: -</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>the username/password.</p></li><li class="listitem"><p>the name of the client machine.</p></li></ol></div><p> -<a class="indexterm" name="id331140"></a> -If the server accepts the username/password credentials, the client expects to be able to mount shares (using -a <span class="emphasis"><em>tree connection</em></span>) without further specifying a password. It expects that all access -rights will be as the username/password credentials set that was specified in the initial <span class="emphasis"><em>session -setup</em></span>. -</p><p> -<a class="indexterm" name="id331158"></a> -It is also possible for a client to send multiple <span class="emphasis"><em>session setup</em></span> -requests. When the server responds, it gives the client a <span class="emphasis"><em>uid</em></span> to use -as an authentication tag for that username/password. The client can maintain multiple -authentication contexts in this way (WinDD is an example of an application that does this). -</p><p> -<a class="indexterm" name="id331177"></a> -<a class="indexterm" name="id331183"></a> -<a class="indexterm" name="id331189"></a> -<a class="indexterm" name="id331195"></a> -<a class="indexterm" name="id331202"></a> -Windows networking user account names are case-insensitive, meaning that upper-case and lower-case characters -in the account name are considered equivalent. They are said to be case-preserving, but not case significant. -Windows and LanManager systems previous to Windows NT version 3.10 have case-insensitive passwords that were -not necessarily case-preserving. All Windows NT family systems treat passwords as case-preserving and -case-sensitive. -</p><div class="sect3" title="Example Configuration"><div class="titlepage"><div><div><h4 class="title"><a name="id331213"></a>Example Configuration</h4></div></div></div><p> -The <code class="filename">smb.conf</code> parameter that sets user-level security is: -</p><table border="0" summary="Simple list" class="simplelist"><tr><td><a class="indexterm" name="id331233"></a><em class="parameter"><code>security = user</code></em></td></tr></table><p> -This is the default setting since Samba-2.2.x. -</p></div></div><div class="sect2" title="Share-Level Security"><div class="titlepage"><div><div><h3 class="title"><a name="id331249"></a>Share-Level Security</h3></div></div></div><p> -<a class="indexterm" name="id331256"></a> -<a class="indexterm" name="id331262"></a> -In share-level security, the client authenticates itself separately for each share. It sends a password along -with each tree connection request (share mount), but it does not explicitly send a username with this -operation. The client expects a password to be associated with each share, independent of the user. This means -that Samba has to work out what username the client probably wants to use, -because the username is not explicitly sent to the SMB server. Some commercial SMB servers such as NT actually associate passwords directly with shares -in share-level security, but Samba always uses the UNIX authentication scheme where it is a username/password -pair that is authenticated, not a share/password pair. -</p><p> -To understand the MS Windows networking parallels, think in terms of MS Windows 9x/Me where you can create a -shared folder that provides read-only or full access, with or without a password. -</p><p> -Many clients send a session setup request even if the server is in share-level security. They normally send a valid -username but no password. Samba records this username in a list of possible usernames. When the client then -issues a tree connection request, it also adds to this list the name of the share they try to connect to (useful for -home directories) and any users listed in the <a class="link" href="smb.conf.5.html#USER" target="_top">user</a> parameter in the <code class="filename">smb.conf</code> file. -The password is then checked in turn against these possible usernames. If a match is found, then the client is -authenticated as that user. -</p><p> -<a class="indexterm" name="id331308"></a> -<a class="indexterm" name="id331317"></a> -<a class="indexterm" name="id331323"></a> -Where the list of possible user names is not provided, Samba makes a UNIX system call to find the user -account that has a password that matches the one provided from the standard account database. On a system that -has no name service switch (NSS) facility, such lookups will be from the <code class="filename">/etc/passwd</code> -database.

The centralized account repository is shared between domain (security) controllers. Servers that -act as domain controllers provide authentication and validation services to all machines that participate in -the security context for the domain. A primary domain controller (PDC) is a server that is responsible for -maintaining the integrity of the security account database.

By contrast, the - <acronym class="acronym">GNU</acronym> General Public License is intended to guarantee your - freedom to share and change all versions of a program—to make sure it - remains free software for all its users. We, the Free Software Foundation, - use the <acronym class="acronym">GNU</acronym> General Public License for most of our - software; it applies also to any other work released this way by its - authors. You can apply it to your programs, too. - </p><p> - When we speak of free software, we are referring to freedom, not price. Our - General Public Licenses are designed to make sure that you have the freedom - to distribute copies of free software (and charge for them if you wish), - that you receive source code or can get it if you want it, that you can - change the software or use pieces of it in new free programs, and that you - know you can do these things. - </p><p> - To protect your rights, we need to prevent others from denying you these - rights or asking you to surrender the rights. Therefore, you have certain - responsibilities if you distribute copies of the software, or if you modify - it: responsibilities to respect the freedom of others. - </p><p> - For example, if you distribute copies of such a program, whether gratis or - for a fee, you must pass on to the recipients the same freedoms that you - received. You must make sure that they, too, receive or can get the source - code. And you must show them these terms so they know their rights. - </p><p> - Developers that use the <acronym class="acronym">GNU</acronym> <acronym class="acronym">GPL</acronym> - protect your rights with two steps: (1) assert copyright on the software, - and (2) offer you this License giving you legal permission to copy, - distribute and/or modify it. - </p><p> - For the developers’ and authors’ protection, the - <acronym class="acronym">GPL</acronym> clearly explains that there is no warranty for this - free software. For both users’ and authors’ sake, the - <acronym class="acronym">GPL</acronym> requires that modified versions be marked as changed, - so that their problems will not be attributed erroneously to authors of - previous versions. - </p><p> - Some devices are designed to deny users access to install or run modified - versions of the software inside them, although the manufacturer can do so. - This is fundamentally incompatible with the aim of protecting users’ - freedom to change the software. The systematic pattern of such abuse occurs - in the area of products for individuals to use, which is precisely where it - is most unacceptable. Therefore, we have designed this version of the - <acronym class="acronym">GPL</acronym> to prohibit the practice for those products. If such - problems arise substantially in other domains, we stand ready to extend this - provision to those domains in future versions of the <acronym class="acronym">GPL</acronym>, - as needed to protect the freedom of users. - </p><p> - Finally, every program is threatened constantly by software patents. States - should not allow patents to restrict development and use of software on - general-purpose computers, but in those that do, we wish to avoid the - special danger that patents applied to a free program could make it - effectively proprietary. To prevent this, the <acronym class="acronym">GPL</acronym> - assures that patents cannot be used to render the program non-free. - </p><p> - The precise terms and conditions for copying, distribution and modification - follow. - </p><h2><a name="id454778"></a> - TERMS AND CONDITIONS - </h2><h2><a name="id454782"></a> - 0.

Each licensee is addressed as “you”. - “Licensees” and “recipients” may be individuals or - organizations. - </p><p> - To “modify” a work means to copy from or adapt all or part of - the work in a fashion requiring copyright permission, other than the making - of an exact copy. The resulting work is called a “modified - version” of the earlier work or a work “based on” the - earlier work. - </p><p> - A “covered work” means either the unmodified Program or a work - based on the Program. - </p><p> - To “propagate” a work means to do anything with it that, without - permission, would make you directly or secondarily liable for infringement - under applicable copyright law, except executing it on a computer or - modifying a private copy. Propagation includes copying, distribution (with - or without modification), making available to the public, and in some - countries other activities as well. - </p><p> - To “convey” a work means any kind of propagation that enables - other parties to make or receive copies. Mere interaction with a user - through a computer network, with no transfer of a copy, is not conveying. - </p><p> - An interactive user interface displays “Appropriate Legal - Notices” to the extent that it includes a convenient and prominently - visible feature that (1) displays an appropriate copyright notice, and (2) - tells the user that there is no warranty for the work (except to the extent - that warranties are provided), that licensees may convey the work under this - License, and how to view a copy of this License.

Source Code. - </h2><p> - The “source code” for a work means the preferred form of the - work for making modifications to it. “Object code” means any - non-source form of a work. - </p><p> - A “Standard Interface” means an interface that either is an - official standard defined by a recognized standards body, or, in the case of - interfaces specified for a particular programming language, one that is - widely used among developers working in that language. - </p><p> - The “System Libraries” of an executable work include anything, - other than the work as a whole, that (a) is included in the normal form of - packaging a Major Component, but which is not part of that Major Component, - and (b) serves only to enable use of the work with that Major Component, or - to implement a Standard Interface for which an implementation is available - to the public in source code form. A “Major Component”, in this - context, means a major essential component (kernel, window system, and so - on) of the specific operating system (if any) on which the executable work - runs, or a compiler used to produce the work, or an object code interpreter - used to run it. - </p><p> - The “Corresponding Source” for a work in object code form means - all the source code needed to generate, install, and (for an executable - work) run the object code and to modify the work, including scripts to - control those activities. However, it does not include the work’s - System Libraries, or general-purpose tools or generally available free - programs which are used unmodified in performing those activities but which - are not part of the work. For example, Corresponding Source includes - interface definition files associated with source files for the work, and - the source code for shared libraries and dynamically linked subprograms that - the work is specifically designed to require, such as by intimate data - communication or control flow between those subprograms and other parts of - the work. - </p><p> - The Corresponding Source need not include anything that users can regenerate - automatically from other parts of the Corresponding Source. - </p><p> - The Corresponding Source for a work in source code form is that same work. - </p><h2><a name="id454908"></a> - 2.

This License acknowledges your rights of fair use or other - equivalent, as provided by copyright law. - </p><p> - You may make, run and propagate covered works that you do not convey, - without conditions so long as your license otherwise remains in force. You - may convey covered works to others for the sole purpose of having them make - modifications exclusively for you, or provide you with facilities for - running those works, provided that you comply with the terms of this License - in conveying all material for which you do not control copyright. Those - thus making or running the covered works for you must do so exclusively on - your behalf, under your direction and control, on terms that prohibit them - from making any copies of your copyrighted material outside their - relationship with you. - </p><p> - Conveying under any other circumstances is permitted solely under the - conditions stated below. Sublicensing is not allowed; section 10 makes it - unnecessary. - </p><h2><a name="id454936"></a> - 3.

Conveying Verbatim Copies. - </h2><p> - You may convey verbatim copies of the Program’s source code as you - receive it, in any medium, provided that you conspicuously and appropriately - publish on each copy an appropriate copyright notice; keep intact all - notices stating that this License and any non-permissive terms added in - accord with section 7 apply to the code; keep intact all notices of the - absence of any warranty; and give all recipients a copy of this License - along with the Program. - </p><p> - You may charge any price or no price for each copy that you convey, and you - may offer support or warranty protection for a fee. - </p><h2><a name="id454977"></a> - 5. Conveying Modified Source Versions. - </h2><p> - You may convey a work based on the Program, or the modifications to produce - it from the Program, in the form of source code under the terms of section - 4, provided that you also meet all of these conditions: - </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p> - The work must carry prominent notices stating that you modified it, and - giving a relevant date. - </p></li><li class="listitem"><p> - The work must carry prominent notices stating that it is released under - this License and any conditions added under section 7. This requirement - modifies the requirement in section 4 to “keep intact all - notices”. - </p></li><li class="listitem"><p> - You must license the entire work, as a whole, under this License to - anyone who comes into possession of a copy. This License will therefore - apply, along with any applicable section 7 additional terms, to the - whole of the work, and all its parts, regardless of how they are - packaged. This License gives no permission to license the work in any - other way, but it does not invalidate such permission if you have - separately received it. - </p></li><li class="listitem"><p> - If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your work need - not make them do so. - </p></li></ol></div><p> - A compilation of a covered work with other separate and independent works, - which are not by their nature extensions of the covered work, and which are - not combined with it such as to form a larger program, in or on a volume of - a storage or distribution medium, is called an “aggregate” if - the compilation and its resulting copyright are not used to limit the access - or legal rights of the compilation’s users beyond what the individual works - permit. Inclusion of a covered work in an aggregate does not cause - this License to apply to the other parts of the aggregate. - </p><h2><a name="id455049"></a> - 6. Conveying Non-Source Forms. - </h2><p> - You may convey a covered work in object code form under the terms of - sections 4 and 5, provided that you also convey the machine-readable - Corresponding Source under the terms of this License, in one of these ways: - </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p> - Convey the object code in, or embodied in, a physical product (including - a physical distribution medium), accompanied by the Corresponding Source - fixed on a durable physical medium customarily used for software - interchange. - </p></li><li class="listitem"><p> - Convey the object code in, or embodied in, a physical product (including - a physical distribution medium), accompanied by a written offer, valid - for at least three years and valid for as long as you offer spare parts - or customer support for that product model, to give anyone who possesses - the object code either (1) a copy of the Corresponding Source for all - the software in the product that is covered by this License, on a - durable physical medium customarily used for software interchange, for a - price no more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the Corresponding Source from - a network server at no charge. - </p></li><li class="listitem"><p> - Convey individual copies of the object code with a copy of the written - offer to provide the Corresponding Source. This alternative is allowed - only occasionally and noncommercially, and only if you received the - object code with such an offer, in accord with subsection 6b. - </p></li><li class="listitem"><p> - Convey the object code by offering access from a designated place - (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to copy - the object code is a network server, the Corresponding Source may be on - a different server (operated by you or a third party) that supports - equivalent copying facilities, provided you maintain clear directions - next to the object code saying where to find the Corresponding Source. - Regardless of what server hosts the Corresponding Source, you remain - obligated to ensure that it is available for as long as needed to - satisfy these requirements. - </p></li><li class="listitem"><p> - Convey the object code using peer-to-peer transmission, provided you - inform other peers where the object code and Corresponding Source of the - work are being offered to the general public at no charge under - subsection 6d. - </p></li></ol></div><p> - A separable portion of the object code, whose source code is excluded from - the Corresponding Source as a System Library, need not be included in - conveying the object code work. - </p><p> - A “User Product” is either (1) a “consumer product”, - which means any tangible personal property which is normally used for - personal, family, or household purposes, or (2) anything designed or sold - for incorporation into a dwelling. In determining whether a product is a - consumer product, doubtful cases shall be resolved in favor of coverage. - For a particular product received by a particular user, “normally - used” refers to a typical or common use of that class of product, - regardless of the status of the particular user or of the way in which the - particular user actually uses, or expects or is expected to use, the - product. A product is a consumer product regardless of whether the product - has substantial commercial, industrial or non-consumer uses, unless such - uses represent the only significant mode of use of the product. - </p><p> - “Installation Information” for a User Product means any methods, - procedures, authorization keys, or other information required to install and - execute modified versions of a covered work in that User Product from a - modified version of its Corresponding Source. The information must suffice - to ensure that the continued functioning of the modified object code is in - no case prevented or interfered with solely because modification has been - made. - </p><p> - If you convey an object code work under this section in, or with, or - specifically for use in, a User Product, and the conveying occurs as part of - a transaction in which the right of possession and use of the User Product - is transferred to the recipient in perpetuity or for a fixed term - (regardless of how the transaction is characterized), the Corresponding - Source conveyed under this section must be accompanied by the Installation - Information. But this requirement does not apply if neither you nor any - third party retains the ability to install modified object code on the User - Product (for example, the work has been installed in - <acronym class="acronym">ROM</acronym>). - </p><p> - The requirement to provide Installation Information does not include a - requirement to continue to provide support service, warranty, or updates for - a work that has been modified or installed by the recipient, or for the User - Product in which it has been modified or installed. Access to a network may - be denied when the modification itself materially and adversely affects the - operation of the network or violates the rules and protocols for - communication across the network. - </p><p> - Corresponding Source conveyed, and Installation Information provided, in - accord with this section must be in a format that is publicly documented - (and with an implementation available to the public in source code form), - and must require no special password or key for unpacking, reading or - copying. - </p><h2><a name="id455181"></a> - 7. Additional Terms. - </h2><p> - “Additional permissions” are terms that supplement the terms of - this License by making exceptions from one or more of its conditions. - Additional permissions that are applicable to the entire Program shall be - treated as though they were included in this License, to the extent that - they are valid under applicable law. If additional permissions apply only - to part of the Program, that part may be used separately under those - permissions, but the entire Program remains governed by this License - without regard to the additional permissions. - </p><p> - When you convey a copy of a covered work, you may at your option remove any - additional permissions from that copy, or from any part of it. (Additional - permissions may be written to require their own removal in certain cases - when you modify the work.) You may place additional permissions on - material, added by you to a covered work, for which you have or can give - appropriate copyright permission. - </p><p> - Notwithstanding any other provision of this License, for material you add - to a covered work, you may (if authorized by the copyright holders of that - material) supplement the terms of this License with terms: - </p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p> - Disclaiming warranty or limiting liability differently from the terms - of sections 15 and 16 of this License; or - </p></li><li class="listitem"><p> - Requiring preservation of specified reasonable legal notices or author - attributions in that material or in the Appropriate Legal Notices - displayed by works containing it; or - </p></li><li class="listitem"><p> - Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - </p></li><li class="listitem"><p> - Limiting the use for publicity purposes of names of licensors or - authors of the material; or - </p></li><li class="listitem"><p> - Declining to grant rights under trademark law for use of some trade - names, trademarks, or service marks; or - </p></li><li class="listitem"><p> - Requiring indemnification of licensors and authors of that material by - anyone who conveys the material (or modified versions of it) with - contractual assumptions of liability to the recipient, for any - liability that these contractual assumptions directly impose on those - licensors and authors. - </p></li></ol></div><p> - All other non-permissive additional terms are considered “further - restrictions” within the meaning of section 10. If the Program as - you received it, or any part of it, contains a notice stating that it is - governed by this License along with a term that is a further restriction, - you may remove that term. If a license document contains a further - restriction but permits relicensing or conveying under this License, you - may add to a covered work material governed by the terms of that license - document, provided that the further restriction does not survive such - relicensing or conveying. - </p><p> - If you add terms to a covered work in accord with this section, you must - place, in the relevant source files, a statement of the additional terms - that apply to those files, or a notice indicating where to find the - applicable terms. - </p><p> - Additional terms, permissive or non-permissive, may be stated in the form - of a separately written license, or stated as exceptions; the above - requirements apply either way. - </p><h2><a name="id455286"></a> - 8. Termination. - </h2><p> - You may not propagate or modify a covered work except as expressly provided - under this License. Any attempt otherwise to propagate or modify it is - void, and will automatically terminate your rights under this License - (including any patent licenses granted under the third paragraph of section - 11). - </p><p> - However, if you cease all violation of this License, then your license from - a particular copyright holder is reinstated (a) provisionally, unless and - until the copyright holder explicitly and finally terminates your license, - and (b) permanently, if the copyright holder fails to notify you of the - violation by some reasonable means prior to 60 days after the cessation. - </p><p> - Moreover, your license from a particular copyright holder is reinstated - permanently if the copyright holder notifies you of the violation by some - reasonable means, this is the first time you have received notice of - violation of this License (for any work) from that copyright holder, and - you cure the violation prior to 30 days after your receipt of the notice. - </p><p> - Termination of your rights under this section does not terminate the - licenses of parties who have received copies or rights from you under this - License. If your rights have been terminated and not permanently - reinstated, you do not qualify to receive new licenses for the same - material under section 10. - </p><h2><a name="id455318"></a> - 9. Acceptance Not Required for Having Copies. - </h2><p> - You are not required to accept this License in order to receive or run a - copy of the Program. Ancillary propagation of a covered work occurring - solely as a consequence of using peer-to-peer transmission to receive a - copy likewise does not require acceptance. However, nothing other than - this License grants you permission to propagate or modify any covered work. - These actions infringe copyright if you do not accept this License. - Therefore, by modifying or propagating a covered work, you indicate your - acceptance of this License to do so. - </p><h2><a name="id455337"></a> - 10. Automatic Licensing of Downstream Recipients. - </h2><p> - Each time you convey a covered work, the recipient automatically receives a - license from the original licensors, to run, modify and propagate that - work, subject to this License. You are not responsible for enforcing - compliance by third parties with this License. - </p><p> - An “entity transaction” is a transaction transferring control - of an organization, or substantially all assets of one, or subdividing an - organization, or merging organizations. If propagation of a covered work - results from an entity transaction, each party to that transaction who - receives a copy of the work also receives whatever licenses to the work the - party’s predecessor in interest had or could give under the previous - paragraph, plus a right to possession of the Corresponding Source of the - work from the predecessor in interest, if the predecessor has it or can get - it with reasonable efforts. - </p><p> - You may not impose any further restrictions on the exercise of the rights - granted or affirmed under this License. For example, you may not impose a - license fee, royalty, or other charge for exercise of rights granted under - this License, and you may not initiate litigation (including a cross-claim - or counterclaim in a lawsuit) alleging that any patent claim is infringed - by making, using, selling, offering for sale, or importing the Program or - any portion of it. - </p><h2><a name="id455370"></a> - 11. Patents. - </h2><p> - A “contributor” is a copyright holder who authorizes use under - this License of the Program or a work on which the Program is based. The - work thus licensed is called the contributor’s “contributor - version”. - </p><p> - A contributor’s “essential patent claims” are all patent - claims owned or controlled by the contributor, whether already acquired or - hereafter acquired, that would be infringed by some manner, permitted by - this License, of making, using, or selling its contributor version, but do - not include claims that would be infringed only as a consequence of further - modification of the contributor version. For purposes of this definition, - “control” includes the right to grant patent sublicenses in a - manner consistent with the requirements of this License. - </p><p> - Each contributor grants you a non-exclusive, worldwide, royalty-free patent - license under the contributor’s essential patent claims, to make, use, - sell, offer for sale, import and otherwise run, modify and propagate the - contents of its contributor version. - </p><p> - In the following three paragraphs, a “patent license” is any - express agreement or commitment, however denominated, not to enforce a - patent (such as an express permission to practice a patent or covenant not - to sue for patent infringement). To “grant” such a patent - license to a party means to make such an agreement or commitment not to - enforce a patent against the party. - </p><p> - If you convey a covered work, knowingly relying on a patent license, and the - Corresponding Source of the work is not available for anyone to copy, free - of charge and under the terms of this License, through a publicly available - network server or other readily accessible means, then you must either (1) - cause the Corresponding Source to be so available, or (2) arrange to deprive - yourself of the benefit of the patent license for this particular work, or - (3) arrange, in a manner consistent with the requirements of this License, - to extend the patent license to downstream recipients. “Knowingly - relying” means you have actual knowledge that, but for the patent - license, your conveying the covered work in a country, or your - recipient’s use of the covered work in a country, would infringe one - or more identifiable patents in that country that you have reason to believe - are valid. - </p><p> - If, pursuant to or in connection with a single transaction or arrangement, - you convey, or propagate by procuring conveyance of, a covered work, and - grant a patent license to some of the parties receiving the covered work - authorizing them to use, propagate, modify or convey a specific copy of the - covered work, then the patent license you grant is automatically extended to - all recipients of the covered work and works based on it. - </p><p> - A patent license is “discriminatory” if it does not include - within the scope of its coverage, prohibits the exercise of, or is - conditioned on the non-exercise of one or more of the rights that are - specifically granted under this License. You may not convey a covered work - if you are a party to an arrangement with a third party that is in the - business of distributing software, under which you make payment to the third - party based on the extent of your activity of conveying the work, and under - which the third party grants, to any of the parties who would receive the - covered work from you, a discriminatory patent license (a) in connection - with copies of the covered work conveyed by you (or copies made from those - copies), or (b) primarily for and in connection with specific products or - compilations that contain the covered work, unless you entered into that - arrangement, or that patent license was granted, prior to 28 March 2007. - </p><p> - Nothing in this License shall be construed as excluding or limiting any - implied license or other defenses to infringement that may otherwise be - available to you under applicable patent law. - </p><h2><a name="id455459"></a> - 12. No Surrender of Others’ Freedom. - </h2><p> - If conditions are imposed on you (whether by court order, agreement or - otherwise) that contradict the conditions of this License, they do not - excuse you from the conditions of this License. If you cannot convey a - covered work so as to satisfy simultaneously your obligations under this - License and any other pertinent obligations, then as a consequence you may - not convey it at all. For example, if you agree to terms that obligate you - to collect a royalty for further conveying from those to whom you convey the - Program, the only way you could satisfy both those terms and this License - would be to refrain entirely from conveying the Program. - </p><h2><a name="id455475"></a> - 13. Use with the <acronym class="acronym">GNU</acronym> Affero General Public License. - </h2><p> - Notwithstanding any other provision of this License, you have permission to - link or combine any covered work with a work licensed under version 3 of the - <acronym class="acronym">GNU</acronym> Affero General Public License into a single combined - work, and to convey the resulting work. The terms of this License will - continue to apply to the part which is the covered work, but the special - requirements of the <acronym class="acronym">GNU</acronym> Affero General Public License, - section 13, concerning interaction through a network will apply to the - combination as such. - </p><h2><a name="id455498"></a> - 14. Revised Versions of this License. - </h2><p> - The Free Software Foundation may publish revised and/or new versions of the - <acronym class="acronym">GNU</acronym> General Public License from time to time. Such new - versions will be similar in spirit to the present version, but may differ in - detail to address new problems or concerns. - </p><p> - Each version is given a distinguishing version number. If the Program - specifies that a certain numbered version of the <acronym class="acronym">GNU</acronym> - General Public License “or any later version” applies to it, you - have the option of following the terms and conditions either of that - numbered version or of any later version published by the Free Software - Foundation. If the Program does not specify a version number of the - <acronym class="acronym">GNU</acronym> General Public License, you may choose any version - ever published by the Free Software Foundation. - </p><p> - If the Program specifies that a proxy can decide which future versions of - the <acronym class="acronym">GNU</acronym> General Public License can be used, that - proxy’s public statement of acceptance of a version permanently - authorizes you to choose that version for the Program. - </p><p> - Later license versions may give you additional or different permissions. - However, no additional obligations are imposed on any author or copyright - holder as a result of your choosing to follow a later version. - </p><h2><a name="id455545"></a> - 15. Disclaimer of Warranty. - </h2><p> - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE - LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR - OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF - ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE - IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. - THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH - YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL - NECESSARY SERVICING, REPAIR OR CORRECTION. - </p><h2><a name="id455563"></a> - 16. Limitation of Liability. - </h2><p> - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL - ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE - PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY - GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE - OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA - OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD - PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), - EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF - SUCH DAMAGES. - </p><h2><a name="id455577"></a> - 17. Interpretation of Sections 15 and 16. - </h2><p> - If the disclaimer of warranty and limitation of liability provided above - cannot be given local legal effect according to their terms, reviewing - courts shall apply local law that most closely approximates an absolute - waiver of all civil liability in connection with the Program, unless a - warranty or assumption of liability accompanies a copy of the Program in - return for a fee. - </p><h2><a name="id455590"></a> - END OF TERMS AND CONDITIONS - </h2><h2><a name="id455594"></a> - How to Apply These Terms to Your New Programs - </h2><p> - If you develop a new program, and you want it to be of the greatest possible - use to the public, the best way to achieve this is to make it free software - which everyone can redistribute and change under these terms. - </p><p> - To do so, attach the following notices to the program. It is safest to - attach them to the start of each source file to most effectively state the - exclusion of warranty; and each file should have at least the - “copyright” line and a pointer to where the full notice is - found. - </p><pre class="screen"> -<em class="replaceable"><code>one line to give the program’s name and a brief idea of what it does.</code></em> -Copyright (C) <em class="replaceable"><code>year</code></em> <em class="replaceable"><code>name of author</code></em> - -This program is free software: you can redistribute it and/or modify -it under the terms of the <acronym class="acronym">GNU</acronym> General Public License as published by -the Free Software Foundation, either version 3 of the License, or -(at your option) any later version. - -This program is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It can be made as tightly or as loosely secured as needs dictate. -Configurations may be simple or complex. Available authentication schemes are essentially the same as -described for file services in previous chapters. Overall, Samba's printing support is now able to replace an -NT or Windows 2000 print server full-square, with additional benefits in many cases. Clients may download and -install drivers and printers through their familiar <code class="literal">Point'n'Print</code> mechanism. Printer -installations executed by <code class="literal">Logon Scripts</code> are no problem. Administrators can upload and manage -drivers to be used by clients through the familiar <code class="literal">Add Printer Wizard</code>. As an additional -benefit, driver and printer management may be run from the command line or through scripts, making it more -efficient in case of large numbers of printers. If a central accounting of print jobs (tracking every single -page and supplying the raw data for all sorts of statistical reports) is required, this function is best -supported by the newer Common UNIX Printing System (CUPS) as the print subsystem underneath the Samba hood. -</p><p> -<a class="indexterm" name="id389148"></a> -<a class="indexterm" name="id389154"></a> -This chapter outlines the fundamentals of Samba printing as implemented by the more traditional UNIX -BSD- and System V-style printing systems.

Samba is a -<code class="literal">middleman.</code> It takes print files from Windows (or other SMB) clients and passes them to the real -printing system for further processing; therefore, it needs to communicate with both sides: the Windows print -clients and the UNIX printing system. Hence, we must differentiate between the various client OS types, each -of which behave differently, as well as the various UNIX print subsystems, which themselves have different -features and are accessed differently. -</p><p> -<a class="indexterm" name="id389244"></a> -<a class="indexterm" name="id389251"></a> -This chapter deals with the traditional way of UNIX printing.

Unfortunately, it is -not enough to just copy the driver files over. They need to be correctly installed so that appropriate records -for each driver will exist in the Samba internal databases so it can provide the correct drivers as they are -requested from MS Windows clients.

You can check the contents of the driver -CDROM that came with your printer. Study the <code class="filename">*.inf</code> files located on the CD-ROM. This -may not be possible, since the <code class="filename">*.inf</code> file might be missing. Unfortunately, vendors have now started -to use their own installation programs. These installations packages are often in some Windows platform -archive format. Additionally, the files may be re-named during the installation process. This makes it -extremely difficult to identify the driver files required. -</p><p> -<a class="indexterm" name="id394532"></a> -Then you have the second option. Install the driver locally on a Windows client and -investigate which filenames and paths it uses after they are installed. (You need to repeat -this procedure for every client platform you want to support.

Then look at the list of -driver files named on the printout. You'll need to recognize what Windows (and Samba) are calling the -<span class="guilabel">Driver File</span>, <span class="guilabel">Data File</span>, <span class="guilabel">Config File</span>, -<span class="guilabel">Help File</span>, and (optionally) <span class="guilabel">Dependent Driver Files</span> -(this may vary slightly for Windows NT).

However, only the last one, which you -arrived at with steps C.1 through C.6 will permanently save any settings which will then become the defaults -for new users. If you want all clients to have the same defaults, you need to conduct these steps as -administrator (<a class="link" href="smb.conf.5.html#PRINTERADMIN" target="_top">printer admin</a>) before a client downloads the driver (the clients can -later set their own per-user defaults by following procedures A or B above). Windows 200x/XP allow per-user -default settings and the ones the administrator gives them before they set up their own. The parents of the -identical-looking dialogs have a slight difference in their window names; one is called -<code class="computeroutput">Default Print Values for Printer Foo on Server Bar</code> (which is the one you -need) and the other is called <span class="quote">“<span class="quote"><code class="computeroutput">Print Settings for Printer Foo on Server -Bar</code></span>”</span>.

The RPC protocol is independent of transport protocols. RPC - does not try to implement any kind of reliability and the application that uses RPCs must be aware of the type - of transport protocol underneath RPC. An RPC is like a programmatic jump subroutine over a network. RPCs used - in the UNIX environment are specified in RFC 1050. RPC is a powerful technique for constructing distributed, - client-server based applications. It is based on extending the notion of conventional, or local procedure - calling, so that the called procedure need not exist in the same address space as the calling procedure. The - two processes may be on the same system, or they may be on different systems with a network connecting them. - By using RPC, programmers of distributed applications avoid the details of the interface with the network. The - transport independence of RPC isolates the application from the physical and logical elements of the data - communications mechanism and allows the application to use a variety of transports. - </p></dd><dt>Server Message Block</dt><dd><p> - SMB was the original name of the protocol `spoken' by - Samba.

For example, if you wanted to include a - UNIX group (e.g., acct) in an ACL on a local file or printer on a Domain Member machine, - you would flag that group as a domain group by running the following on the Samba PDC: - </p><p> -</p><pre class="screen"> -<code class="prompt">root# </code><strong class="userinput"><code>net groupmap add rid=1000 ntgroup="Accounting" unixgroup=acct type=d</code></strong> -</pre><p> - The <code class="literal">ntgroup</code> value must be in quotes if it contains space characters to prevent - the space from being interpreted as a command delimiter. - </p><p> -<a class="indexterm" name="id365672"></a> -<a class="indexterm" name="id365679"></a> - Be aware that the RID parameter is an unsigned 32-bit integer that should - normally start at 1000.

The application of group security - should be implemented on domain member servers using only local groups. On the domain member server, - all file system security controls are then limited to use of the local groups, which will contain - domain global groups and domain global users. - </p><p> -<a class="indexterm" name="id365840"></a> -<a class="indexterm" name="id365847"></a> -<a class="indexterm" name="id365854"></a> - You may ask, What are the benefits of this arrangement? The answer is obvious to those who have plumbed - the dark depths of Windows networking architecture. Consider for a moment a server on which are stored - 200,000 files, each with individual domain user and domain group settings. The company that owns the - file server is bought by another company, resulting in the server being moved to another location, and then - it is made a member of a different domain. Who would you think now owns all the files and directories? - Answer: Account Unknown. - </p><p> -<a class="indexterm" name="id365869"></a> -<a class="indexterm" name="id365876"></a> -<a class="indexterm" name="id365882"></a> -<a class="indexterm" name="id365889"></a> - Unraveling the file ownership mess is an unenviable administrative task that can be avoided simply - by using local groups to control all file and directory access control. In this case, only the members - of the local groups will have been lost. The files and directories in the storage subsystem will still - be owned by the local groups. The same goes for all ACLs on them. It is administratively much simpler - to delete the <code class="constant">Account Unknown</code> membership entries inside local groups with appropriate - entries for domain global groups in the new domain that the server has been made a member of. - </p><p> -<a class="indexterm" name="id365908"></a> -<a class="indexterm" name="id365914"></a> -<a class="indexterm" name="id365921"></a> -<a class="indexterm" name="id365928"></a> -<a class="indexterm" name="id365935"></a> -<a class="indexterm" name="id365942"></a> -<a class="indexterm" name="id365949"></a> -<a class="indexterm" name="id365955"></a> - Another prominent example of the use of nested groups involves implementation of administrative privileges - on domain member workstations and servers. Administrative privileges are given to all members of the - built-in local group <code class="constant">Administrators</code> on each domain member machine. To ensure that all domain - administrators have full rights on the member server or workstation, on joining the domain, the - <code class="constant">Domain Admins</code> group is added to the local Administrators group. Thus everyone who is - logged into the domain as a member of the Domain Admins group is also granted local administrative - privileges on each domain member. - </p><p> -<a class="indexterm" name="id365978"></a> -<a class="indexterm" name="id365985"></a> -<a class="indexterm" name="id365992"></a> -<a class="indexterm" name="id365998"></a> - UNIX/Linux has no concept of support for nested groups, and thus Samba has for a long time not supported - them either. The problem is that you would have to enter UNIX groups as auxiliary members of a group in - <code class="filename">/etc/group</code>. This does not work because it was not a design requirement at the time - the UNIX file system security model was implemented. Since Samba-2.2, the winbind daemon can provide - <code class="filename">/etc/group</code> entries on demand by obtaining user and group information from the domain - controller that the Samba server is a member of. - </p><p> -<a class="indexterm" name="id366024"></a> -<a class="indexterm" name="id366031"></a> -<a class="indexterm" name="id366038"></a> -<a class="indexterm" name="id366045"></a> -<a class="indexterm" name="id366052"></a> - In effect, Samba supplements the <code class="filename">/etc/group</code> data via the dynamic - <code class="literal">libnss_winbind</code> mechanism. Beginning with Samba-3.0.3, this facility is used to provide - local groups in the same manner as Windows. It works by expanding the local groups on the - fly as they are accessed. For example, the <code class="constant">Domain Users</code> group of the domain is made - a member of the local group <code class="constant">demo</code>. Whenever Samba needs to resolve membership of the - <code class="constant">demo</code> local (alias) group, winbind asks the domain controller for demo members of the Domain Users - group. By definition, it can only contain user objects, which can then be faked to be member of the - UNIX/Linux group <code class="constant">demo</code>. - </p><p> -<a class="indexterm" name="id366093"></a> -<a class="indexterm" name="id366099"></a> -<a class="indexterm" name="id366106"></a> -<a class="indexterm" name="id366113"></a> -<a class="indexterm" name="id366120"></a> -<a class="indexterm" name="id366126"></a> -<a class="indexterm" name="id366133"></a> - To enable the use of nested groups, <code class="literal">winbindd</code> must be used with NSS winbind. - Creation and administration of the local groups is done best via the Windows Domain User Manager or its - Samba equivalent, the utility <code class="literal">net rpc group</code>. Creating the local group - <code class="constant">demo</code> is achieved by executing: - </p><pre class="screen"> - <code class="prompt">root# </code> net rpc group add demo -L -Uroot%not24get - </pre><p> -<a class="indexterm" name="id366174"></a> -<a class="indexterm" name="id366180"></a> - Here the -L switch means that you want to create a local group. It may be necessary to add -S and -U - switches for accessing the correct host with appropriate user or root privileges. Adding and removing - group members can be done via the <code class="constant">addmem</code> and <code class="constant">delmem</code> subcommands of - <code class="literal">net rpc group</code> command. For example, addition of <span class="quote">“<span class="quote">DOM\Domain Users</span>”</span> to the - local group <code class="constant">demo</code> is done by executing: - </p><pre class="screen"> - net rpc group addmem demo "DOM\Domain Users" - </pre><p> -<a class="indexterm" name="id366217"></a> -<a class="indexterm" name="id366223"></a> -<a class="indexterm" name="id366230"></a> -<a class="indexterm" name="id366237"></a> - Having completed these two steps, the execution of <code class="literal">getent group demo</code> will show demo - members of the global <code class="constant">Domain Users</code> group as members of the group - <code class="constant">demo</code>. This also works with any local or domain user. In case the domain DOM trusts - another domain, it is also possible to add global users and groups of the trusted domain as members of - <code class="constant">demo</code>. The users from the foreign domain who are members of the group that has been - added to the <code class="constant">demo</code> group now have the same local access permissions as local domain - users have. - </p></div><div class="sect2" title="Important Administrative Information"><div class="titlepage"><div><div><h3 class="title"><a name="id366270"></a>Important Administrative Information</h3></div></div></div><p> - Administrative rights are necessary in two specific forms: - </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p>For Samba-3 domain controllers and domain member servers/clients.</p></li><li class="listitem"><p>To manage domain member Windows workstations.</p></li></ol></div><p> -<a class="indexterm" name="id366300"></a> -<a class="indexterm" name="id366306"></a> -<a class="indexterm" name="id366313"></a> - Versions of Samba up to and including 3.0.10 do not provide a means for assigning rights and privileges - that are necessary for system administration tasks from a Windows domain member client machine, so - domain administration tasks such as adding, deleting, and changing user and group account information, and - managing workstation domain membership accounts, can be handled by any account other than root. - </p><p> -<a class="indexterm" name="id366327"></a> -<a class="indexterm" name="id366334"></a> -<a class="indexterm" name="id366340"></a> - Samba-3.0.11 introduced a new privilege management interface (see <a class="link" href="rights.html" title="Chapter 15.

Windows does not have a concept of the UNIX UID or a GID; rather, - it has its own type of security descriptor. When Samba is used as a domain controller, it provides a method - of producing a unique SID for each user and group. Samba generates a machine and a domain SID to which it - adds an RID that is calculated algorithmically from a base value that can be specified - in the <code class="filename">smb.conf</code> file, plus twice (2x) the UID or GID.

Thus, if the domain SID is - <code class="literal">S-1-5-21-89238497-92787123-12341112</code>, the resulting SID is - <code class="literal">S-1-5-21-89238497-92787123-12341112-9642</code>. - </p><p> - <a class="indexterm" name="id373884"></a> - <a class="indexterm" name="id373891"></a> - <a class="indexterm" name="id373898"></a> - <a class="indexterm" name="id373904"></a> - The foregoing type of SID is produced by Samba as an automatic function and is either produced on the fly - (as is the case when using a <em class="parameter"><code>passdb backend = [tdbsam | smbpasswd]</code></em>), or may be stored - as a permanent part of an account in an LDAP-based ldapsam. - </p><p> - <a class="indexterm" name="id373922"></a> - <a class="indexterm" name="id373929"></a> - <a class="indexterm" name="id373936"></a> - <a class="indexterm" name="id373942"></a> - <a class="indexterm" name="id373949"></a> - <a class="indexterm" name="id373956"></a> - <a class="indexterm" name="id373962"></a> - <a class="indexterm" name="id373969"></a> - <a class="indexterm" name="id373976"></a> - ADS uses a directory schema that can be extended to accommodate additional - account attributes such as UIDs and GIDs.

The - section <code class="literal">[global]</code> is special, since it contains settings that apply to the whole Samba - server. Samba supports a number of meta-services, each of which serves its own purpose. For example, the - <code class="literal">[homes]</code> share is a meta-service that causes Samba to provide a personal home share for - each user. The <code class="literal">[printers]</code> share is a meta-service that establishes print queue support - and that specifies the location of the intermediate spool directory into which print jobs are received - from Windows clients prior to being dispatched to the UNIX/Linux print spooler. - </p><p> -<a class="indexterm" name="id324449"></a> -<a class="indexterm" name="id324455"></a> -<a class="indexterm" name="id324461"></a> -<a class="indexterm" name="id324467"></a> -<a class="indexterm" name="id324474"></a> -<a class="indexterm" name="id324480"></a> - The <code class="literal">printers</code> meta-service will cause every printer that is either specified in a - <code class="literal">printcap</code> file, via the <code class="literal">lpstat</code>, or via the CUPS API, to be - published as a shared print queue. The <code class="literal">printers</code> stanza in the <code class="filename">smb.conf</code> file can - be set as not browseable. If it is set to be browseable, then it will be visible as if it is a share. - That makes no sense given that this meta-service is responsible only for making UNIX system printers - available as Windows print queues. If a <code class="literal">comment</code> parameter is specified, the value - of it will be displayed as part of the printer name in Windows Explorer browse lists. - </p><p> - <a class="indexterm" name="id324525"></a> - Each section of the <code class="filename">smb.conf</code> file that specifies a share, or a meta-service, is called a stanza. - The <code class="literal">global</code> stanza specifies settings that affect all the other stanzas in the - <code class="filename">smb.conf</code> file.

A daemon is a UNIX application that runs in the background and provides services. - An example of a service is the Apache Web server for which the daemon is called <code class="literal">httpd</code>. In the case of Samba there - are three daemons, two of which are needed as a minimum. - </p><p> - The Samba server is made up of the following daemons: - </p><div class="variablelist"><dl><dt><span class="term">nmbd</span></dt><dd><p> - <a class="indexterm" name="id325217"></a> - <a class="indexterm" name="id325223"></a> - This daemon handles all name registration and resolution requests. It is the primary vehicle involved - in network browsing. It handles all UDP-based protocols. The <code class="literal">nmbd</code> daemon should - be the first command started as part of the Samba startup process. - </p></dd><dt><span class="term">smbd</span></dt><dd><p> - <a class="indexterm" name="id325249"></a> - <a class="indexterm" name="id325255"></a> - This daemon handles all TCP/IP-based connection services for file- and print-based operations. It also - manages local authentication. It should be started immediately following the startup of <code class="literal">nmbd</code>. - </p></dd><dt><span class="term">winbindd</span></dt><dd><p> - <a class="indexterm" name="id325280"></a> - <a class="indexterm" name="id325286"></a> - This daemon should be started when Samba is a member of a Windows NT4 or ADS domain. It is also needed when - Samba has trust relationships with another domain. The <code class="literal">winbindd</code> daemon will check the - <code class="filename">smb.conf</code> file for the presence of the <em class="parameter"><code>idmap uid</code></em> and <em class="parameter"><code>idmap gid</code></em> - parameters. If they are are found, <code class="literal">winbindd</code> will use the values specified for - for UID and GID allocation. If these parameters are not specified, <code class="literal">winbindd</code> - will start but it will not be able to allocate UIDs or GIDs. - </p></dd></dl></div><p> - <a class="indexterm" name="id325334"></a> - When Samba has been packaged by an operating system vendor, the startup process is typically a custom feature of its - integration into the platform as a whole. Please refer to your operating system platform administration manuals for - specific information pertaining to correct management of Samba startup. - </p></div><div class="sect2" title="Example Configuration"><div class="titlepage"><div><div><h3 class="title"><a name="id325348"></a>Example Configuration</h3></div></div></div><p> - <a class="indexterm" name="id325355"></a> - <a class="indexterm" name="id325361"></a> - <a class="indexterm" name="id325368"></a> - <a class="indexterm" name="id325374"></a> - <a class="indexterm" name="id325380"></a> - There are sample configuration files in the examples subdirectory in the source code distribution tarball - package.

It is good practice to - keep this file as small as possible. Many administrators prefer to document Samba configuration settings - and thus the need to keep this file small goes against good documentation wisdom. One solution that may - be adopted is to do all documentation and configuration in a file that has another name, such as - <code class="filename">smb.conf.master</code>.

In most situations -with peer-to-peer networking, the users who control their own machines -will simply opt to have no security at all.

Versions of Samba before 2.2 have tried to use the native fcntl() UNIX -system call to implement proper record locking between different Samba clients. -This cannot be fully correct for several reasons. The simplest is -that a Windows client is allowed to lock a byte range up to 2^32 or 2^64, -depending on the client OS. The UNIX locking only supports byte ranges up to 2^31. -So it is not possible to correctly satisfy a lock request above 2^31. There are -many more differences, too many to be listed here. -</p><p> -<a class="indexterm" name="id383249"></a> -<a class="indexterm" name="id383256"></a> -Samba 2.2 and above implement record locking completely independently of the -underlying UNIX system. If a byte-range lock that the client requests happens -to fall into the range of 0 to 2^31, Samba hands this request down to the UNIX system. -No other locks can be seen by UNIX, anyway. -</p><p> -<a class="indexterm" name="id383269"></a> -<a class="indexterm" name="id383276"></a> -Strictly speaking, an SMB server should check for locks before every read and write call on -a file. Unfortunately, with the way fcntl() works, this can be slow and may overstress -the <code class="literal">rpc.lockd</code>. This is almost always unnecessary because clients are -independently supposed to make locking calls before reads and writes if locking is -important to them. By default, Samba only makes locking calls when explicitly asked -to by a client, but if you set <a class="link" href="smb.conf.5.html#STRICTLOCKING" target="_top">strict locking = yes</a>, it -will make lock checking calls on <span class="emphasis"><em>every</em></span> read and write call. -</p><p> -<a class="indexterm" name="id383312"></a> -You can also disable byte-range locking completely by using -<a class="link" href="smb.conf.5.html#LOCKING" target="_top">locking = no</a>. -This is useful for those shares that do not support locking or do not need it -(such as CD-ROMs).

Because of the lightweight -nature of the Windows feature design, effective configuration of -oplocks requires a good understanding of its limitations, -and then applying that understanding when configuring data access for -each particular customized network and client usage state. -</p><p> -Oplocks essentially means that the client is allowed to download and cache -a file on its hard drive while making changes; if a second client wants to access the -file, the first client receives a break and must synchronize the file back to the server. -This can give significant performance gains in some cases; some programs insist on -synchronizing the contents of the entire file back to the server for a single change. -</p><p> -Level1 Oplocks (also known as just plain <span class="quote">“<span class="quote">oplocks</span>”</span>) is another term for opportunistic locking. -</p><p> -Level2 Oplocks provides opportunistic locking for a file that will be treated as -<span class="emphasis"><em>read only</em></span>. Typically this is used on files that are read-only or -on files that the client has no initial intention to write to at time of opening the file. -</p><p> -Kernel Oplocks are essentially a method that allows the Linux kernel to co-exist with -Samba's oplocked files, although this has provided better integration of MS Windows network -file locking with the underlying OS. SGI IRIX and Linux are the only two OSs that are -oplock-aware at this time. -</p><p> -Unless your system supports kernel oplocks, you should disable oplocks if you are -accessing the same files from both UNIX/Linux and SMB clients. Regardless, oplocks should -always be disabled if you are sharing a database file (e.g., Microsoft Access) between -multiple clients, because any break the first client receives will affect synchronization of -the entire file (not just the single record), which will result in a noticeable performance -impairment and, more likely, problems accessing the database in the first place. Notably, -Microsoft Outlook's personal folders (*.pst) react quite badly to oplocks. If in doubt, -disable oplocks and tune your system from that point. -</p><p> -If client-side caching is desirable and reliable on your network, you will benefit from -turning on oplocks. If your network is slow and/or unreliable, or you are sharing your -files among other file sharing mechanisms (e.g., NFS) or across a WAN, or multiple people -will be accessing the same files frequently, you probably will not benefit from the overhead -of your client sending oplock breaks and will instead want to disable oplocks for the share. -</p><p> -Another factor to consider is the perceived performance of file access. If oplocks provide no -measurable speed benefit on your network, it might not be worth the hassle of dealing with them. -</p><div class="sect2" title="Example Configuration"><div class="titlepage"><div><div><h3 class="title"><a name="id384333"></a>Example Configuration</h3></div></div></div><p> -In the following section we examine two distinct aspects of Samba locking controls. -</p><div class="sect3" title="Disabling Oplocks"><div class="titlepage"><div><div><h4 class="title"><a name="id384342"></a>Disabling Oplocks</h4></div></div></div><p> -You can disable oplocks on a per-share basis with the following: -</p><p> -</p><table border="0" summary="Simple list" class="simplelist"><tr><td> </td></tr><tr><td><em class="parameter"><code>[acctdata]</code></em></td></tr><tr><td><a class="indexterm" name="id384367"></a><em class="parameter"><code>oplocks = False</code></em></td></tr><tr><td><a class="indexterm" name="id384379"></a><em class="parameter"><code>level2 oplocks = False</code></em></td></tr></table><p> -</p><p> -The default oplock type is Level1.

For example, the <span class="quote">“<span class="quote">root</span>”</span> login may be permitted only on the console. - </p></li><li class="listitem"><p> -<a class="indexterm" name="id429223"></a> - <em class="parameter"><code>session:</code></em> Primarily, this module is associated with doing things that need - to be done for the user before and after he or she can be given service.

Since modules can be stacked (modules of the same type execute in series, - one after another), the control-flags determine the relative importance of each module. The application - is not made aware of the individual success or failure of modules listed in the - <code class="filename">/etc/pam.conf</code> file. Instead, it receives a summary success or fail response from - the Linux-PAM library. The order of execution of these modules is that of the entries in the - <code class="filename">/etc/pam.conf</code> file; earlier entries are executed before later ones. - As of Linux-PAM v0.60, this control-flag can be defined with one of two syntaxes. - </p><p> -<a class="indexterm" name="id429299"></a> -<a class="indexterm" name="id429306"></a> -<a class="indexterm" name="id429312"></a> -<a class="indexterm" name="id429319"></a> - The simpler (and historical) syntax for the control-flag is a single keyword defined to indicate the - severity of concern associated with the success or failure of a specific module. There are four such - keywords: <em class="parameter"><code>required</code></em>, <em class="parameter"><code>requisite</code></em>, - <em class="parameter"><code>sufficient</code></em>, and <em class="parameter"><code>optional</code></em>. - </p><p> - The Linux-PAM library interprets these keywords in the following manner: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - <em class="parameter"><code>required:</code></em> This indicates that the success of the module is required for the - module-type facility to succeed. Failure of this module will not be apparent to the user until all - of the remaining modules (of the same module-type) have been executed. - </p></li><li class="listitem"><p> - <em class="parameter"><code>requisite:</code></em> Like required, except that if such a module returns a - failure, control is directly returned to the application. The return value is that associated with - the first required or requisite module to fail. This flag can be used to protect against the - possibility of a user getting the opportunity to enter a password over an unsafe medium. It is - conceivable that such behavior might inform an attacker of valid accounts on a system. This - possibility should be weighed against the not insignificant concerns of exposing a sensitive - password in a hostile environment. - </p></li><li class="listitem"><p> - <em class="parameter"><code>sufficient:</code></em> The success of this module is deemed <em class="parameter"><code>sufficient</code></em> to satisfy - the Linux-PAM library that this module-type has succeeded in its purpose. In the event that no - previous required module has failed, no more <span class="quote">“<span class="quote">stacked</span>”</span> modules of this type are invoked. - (In this case, subsequent required modules are not invoked). A failure of this module is not deemed - as fatal to satisfying the application that this module-type has succeeded. - </p></li><li class="listitem"><p> - <em class="parameter"><code>optional:</code></em> As its name suggests, this control-flag marks the module as not - being critical to the success or failure of the user's application for service. In general, - Linux-PAM ignores such a module when determining if the module stack will succeed or fail. - However, in the absence of any definite successes or failures of previous or subsequent stacked - modules, this module will determine the nature of the response to the application. One example of - this latter case is when the other modules return something like PAM_IGNORE. - </p></li></ul></div><p> - The more elaborate (newer) syntax is much more specific and gives the administrator a great deal of control - over how the user is authenticated. This form of the control-flag is delimited with square brackets and - consists of a series of <em class="parameter"><code>value=action</code></em> tokens: - </p><pre class="programlisting"> -[value1=action1 value2=action2 ...] -</pre><p> - Here, <em class="parameter"><code>value1</code></em> is one of the following return values: -</p><pre class="screen"> -<em class="parameter"><code>success; open_err; symbol_err; service_err; system_err; buf_err;</code></em> -<em class="parameter"><code>perm_denied; auth_err; cred_insufficient; authinfo_unavail;</code></em> -<em class="parameter"><code>user_unknown; maxtries; new_authtok_reqd; acct_expired; session_err;</code></em> -<em class="parameter"><code>cred_unavail; cred_expired; cred_err; no_module_data; conv_err;</code></em> -<em class="parameter"><code>authtok_err; authtok_recover_err; authtok_lock_busy;</code></em> -<em class="parameter"><code>authtok_disable_aging; try_again; ignore; abort; authtok_expired;</code></em> -<em class="parameter"><code>module_unknown; bad_item;</code></em> and <em class="parameter"><code>default</code></em>. -</pre><p> -</p><p> - The last of these (<em class="parameter"><code>default</code></em>) can be used to set the action for those return values that are not explicitly defined. - </p><p> - The <em class="parameter"><code>action1</code></em> can be a positive integer or one of the following tokens: - <em class="parameter"><code>ignore</code></em>; <em class="parameter"><code>ok</code></em>; <em class="parameter"><code>done</code></em>; - <em class="parameter"><code>bad</code></em>; <em class="parameter"><code>die</code></em>; and <em class="parameter"><code>reset</code></em>. - A positive integer, J, when specified as the action, can be used to indicate that the next J modules of the - current module-type will be skipped. In this way, the administrator can develop a moderately sophisticated - stack of modules with a number of different paths of execution. Which path is taken can be determined by the - reactions of individual modules. - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - <em class="parameter"><code>ignore:</code></em> When used with a stack of modules, the module's return status will not - contribute to the return code the application obtains. - </p></li><li class="listitem"><p> - <em class="parameter"><code>bad:</code></em> This action indicates that the return code should be thought of as indicative - of the module failing. If this module is the first in the stack to fail, its status value will be used - for that of the whole stack. - </p></li><li class="listitem"><p> - <em class="parameter"><code>die:</code></em> Equivalent to bad with the side effect of terminating the module stack and - PAM immediately returning to the application. - </p></li><li class="listitem"><p> - <em class="parameter"><code>ok:</code></em> This tells PAM that the administrator thinks this return code should - contribute directly to the return code of the full stack of modules. In other words, if the former - state of the stack would lead to a return of PAM_SUCCESS, the module's return code will override - this value. Note, if the former state of the stack holds some value that is indicative of a module's - failure, this <em class="parameter"><code>ok</code></em> value will not be used to override that value. - </p></li><li class="listitem"><p> - <em class="parameter"><code>done:</code></em> Equivalent to <em class="parameter"><code>ok</code></em> with the side effect of terminating the module stack and - PAM immediately returning to the application. - </p></li><li class="listitem"><p> - <em class="parameter"><code>reset:</code></em> Clears all memory of the state of the module stack and starts again with - the next stacked module. - </p></li></ul></div><p> - Each of the four keywords, <em class="parameter"><code>required</code></em>; <em class="parameter"><code>requisite</code></em>; - <em class="parameter"><code>sufficient</code></em>; and <em class="parameter"><code>optional</code></em>, have an equivalent expression in terms - of the [...] syntax. They are as follows: - </p><p> - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - <em class="parameter"><code>required</code></em> is equivalent to <em class="parameter"><code>[success=ok new_authtok_reqd=ok ignore=ignore default=bad]</code></em>. - </p></li><li class="listitem"><p> - <em class="parameter"><code>requisite</code></em> is equivalent to <em class="parameter"><code>[success=ok new_authtok_reqd=ok ignore=ignore default=die]</code></em>. - </p></li><li class="listitem"><p> - <em class="parameter"><code>sufficient</code></em> is equivalent to <em class="parameter"><code>[success=done new_authtok_reqd=done default=ignore]</code></em>. - </p></li><li class="listitem"><p> - <em class="parameter"><code>optional</code></em> is equivalent to <em class="parameter"><code>[success=ok new_authtok_reqd=ok default=ignore]</code></em>. - </p></li></ul></div><p> - </p><p> - Just to get a feel for the power of this new syntax, here is a taste of what you can do with it. With Linux-PAM-0.63, - the notion of client plug-in agents was introduced. This makes it possible for PAM to support - machine-machine authentication using the transport protocol inherent to the client/server application. With the - <em class="parameter"><code>[ ... value=action ... ]</code></em> control syntax, it is possible for an application to be configured - to support binary prompts with compliant clients, but to gracefully fail over into an alternative authentication - mode for legacy applications. - </p></dd><dt><span class="term">module-path</span></dt><dd><p> - The pathname of the dynamically loadable object file; the pluggable module itself. If the first character of the - module path is <span class="quote">“<span class="quote">/</span>”</span>, it is assumed to be a complete path. If this is not the case, the given module path is appended - to the default module path: <code class="filename">/lib/security</code> (but see the previous notes). - </p><p> - The arguments are a list of tokens that are passed to the module when it is invoked, much like arguments to a typical - Linux shell command. Generally, valid arguments are optional and are specific to any given module. Invalid arguments - are ignored by a module; however, when encountering an invalid argument, the module is required to write an error - to syslog(3). For a list of generic options, see the next section. - </p><p> - If you wish to include spaces in an argument, you should surround that argument with square brackets. For example: - </p><pre class="programlisting"> -squid auth required pam_mysql.so user=passwd_query passwd=mada \ -db=eminence [query=select user_name from internet_service where \ -user_name=<span class="quote">“<span class="quote">%u</span>”</span> and password=PASSWORD(<span class="quote">“<span class="quote">%p</span>”</span>) and service=<span class="quote">“<span class="quote">web_proxy</span>”</span>] -</pre><p> - When using this convention, you can include <span class="quote">“<span class="quote">[</span>”</span> characters inside the string, and if you wish to have a <span class="quote">“<span class="quote">]</span>”</span> - character inside the string that will survive the argument parsing, you should use <span class="quote">“<span class="quote">\[</span>”</span>. In other words, - </p><pre class="programlisting"> -[..[..\]..] --> ..[..].. -</pre><p> - Any line in one of the configuration files that is not formatted correctly will generally tend (erring on the - side of caution) to make the authentication process fail.

It is well understood by LDAP veterans that - first implementations create awakening, second implementations of LDAP create fear, and - third-generation deployments bring peace and tranquility. - </p><div class="sect3" title="Caution Regarding LDAP and Samba"><div class="titlepage"><div><div><h4 class="title"><a name="id358952"></a>Caution Regarding LDAP and Samba</h4></div></div></div><p> -<a class="indexterm" name="id358960"></a> -<a class="indexterm" name="id358967"></a> -<a class="indexterm" name="id358974"></a> -<a class="indexterm" name="id358980"></a> -<a class="indexterm" name="id358987"></a> -<a class="indexterm" name="id358994"></a> -<a class="indexterm" name="id359001"></a> - Samba requires UNIX POSIX identity information as well as a place to store information that is - specific to Samba and the Windows networking environment. The most used information that must - be dealt with includes: user accounts, group accounts, machine trust accounts, interdomain - trust accounts, and intermediate information specific to Samba internals. - </p><p> -<a class="indexterm" name="id359014"></a> -<a class="indexterm" name="id359021"></a> -<a class="indexterm" name="id359028"></a> - The example deployment guidelines in this book, as well as other books and HOWTO documents - available from the internet may not fit with established directory designs and implementations. - The existing DIT may not be able to accommodate the simple information layout proposed in common - sources. Additionally, you may find that the common scripts and tools that are used to provision - the LDAP directory for use with Samba may not suit your needs. - </p><p> -<a class="indexterm" name="id359042"></a> - It is not uncommon, for sites that have existing LDAP DITs to find necessity to generate a - set of site-specific scripts and utilities to make it possible to deploy Samba within the - scope of site operations. The way that user and group accounts are distributed throughout - the DIT may make this a challenging matter. The solution will, of course, be rewarding, but - the journey to it may be challenging. Take time to understand site needs and do not rush - into deployment. - </p><p> -<a class="indexterm" name="id359056"></a> -<a class="indexterm" name="id359063"></a> - Above all, do not blindly use scripts and tools that are not suitable for your site.

It is best to deal with the design and - configuration of an LDAP directory prior to integration with Samba. A working knowledge - of LDAP makes Samba integration easy, and the lack of a working knowledge of LDAP can make - it a frustrating experience. - </p><p> -<a class="indexterm" name="id359109"></a> -<a class="indexterm" name="id359116"></a> -<a class="indexterm" name="id359123"></a> - Computer (machine) accounts can be placed wherever you like in an LDAP directory subject - to some constraints that are described in this chapter. - </p><p> -<a class="indexterm" name="id359134"></a> -<a class="indexterm" name="id359141"></a> -<a class="indexterm" name="id359148"></a> -<a class="indexterm" name="id359155"></a> -<a class="indexterm" name="id359161"></a> -<a class="indexterm" name="id359168"></a> -<a class="indexterm" name="id359175"></a> - The POSIX and sambaSamAccount components of computer (machine) accounts are both used by Samba. - Thus, machine accounts are treated inside Samba in the same way that Windows NT4/200X treats - them. A user account and a machine account are indistinguishable from each other, except that - the machine account ends in a $ character, as do trust accounts. - </p><p> -<a class="indexterm" name="id359188"></a> -<a class="indexterm" name="id359195"></a> -<a class="indexterm" name="id359202"></a> -<a class="indexterm" name="id359208"></a> -<a class="indexterm" name="id359215"></a> - The need for Windows user, group, machine, trust, and other accounts to be tied to a valid UNIX - UID is a design decision that was made a long way back in the history of Samba development. It - is unlikely that this decision will be reversed or changed during the remaining life of the - Samba-3.x series. - </p><p> -<a class="indexterm" name="id359228"></a> -<a class="indexterm" name="id359234"></a> -<a class="indexterm" name="id359241"></a> - The resolution of a UID from the Windows SID is achieved within Samba through a mechanism that - must refer back to the host operating system on which Samba is running. The NSS is the preferred - mechanism that shields applications (like Samba) from the need to know everything about every - host OS it runs on. - </p><p> -<a class="indexterm" name="id359253"></a> -<a class="indexterm" name="id359260"></a> -<a class="indexterm" name="id359267"></a> -<a class="indexterm" name="id359274"></a> -<a class="indexterm" name="id359280"></a> -<a class="indexterm" name="id359287"></a> -<a class="indexterm" name="id359294"></a> - Samba asks the host OS to provide a UID via the <span class="quote">“<span class="quote">passwd</span>”</span>, <span class="quote">“<span class="quote">shadow</span>”</span>, - and <span class="quote">“<span class="quote">group</span>”</span> facilities in the NSS control (configuration) file. The best tool - for achieving this is left up to the UNIX administrator to determine. It is not imposed by - Samba. Samba provides winbindd with its support libraries as one method. It is - possible to do this via LDAP, and for that Samba provides the appropriate hooks so that - all account entities can be located in an LDAP directory. - </p><p> -<a class="indexterm" name="id359318"></a> -<a class="indexterm" name="id359325"></a> -<a class="indexterm" name="id359332"></a> -<a class="indexterm" name="id359338"></a> -<a class="indexterm" name="id359345"></a> - For many the weapon of choice is to use the PADL nss_ldap utility. This utility must - be configured so that computer accounts can be resolved to a POSIX/UNIX account UID. That - is fundamentally an LDAP design question. The information provided on the Samba list and - in the documentation is directed at providing working examples only. The design - of an LDAP directory is a complex subject that is beyond the scope of this documentation. - </p></div></div><div class="sect1" title="Account Management Tools"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="acctmgmttools"></a>Account Management Tools</h2></div></div></div><p> -<a class="indexterm" name="id359371"></a> -<a class="indexterm" name="id359378"></a> -<a class="indexterm" name="id359385"></a> -Samba provides two tools for management of user and machine accounts: -<code class="literal">smbpasswd</code> and <code class="literal">pdbedit</code>. -</p><p> -<a class="indexterm" name="id359407"></a> -<a class="indexterm" name="id359414"></a> -<a class="indexterm" name="id359421"></a> -The <code class="literal">pdbedit</code> can be used to manage account policies in addition to -Samba user account information.

We may look back upon the past to question the motives of those who have - gone before us. Seldom do we realise that the past owes us no answer, and despite what we may think of the - actions of those who have travelled lifes' road before us, we must feel a sense of pride and gratitude for - those who, in the past, have protected our liberties. - </p><p> - Developments in information technology continue to move at an alarming pace. Human nature causes us - to adopt and embrace new developments that appear to answer the needs of the moment, but that can entrap - us at a future date. There are many examples in the short history of information technology. MS-DOS was - seen as a tool that liberated users from the tyrany of large computer system operating costs, and that - made possible the rapid progres we are beneficiaries of today. Yet today we are inclined to look back with - disdain on MS-DOS as an obsolete and constraining technology that belongs are an era that is best - forgotten. - </p><p> - The embrace of Windows networking, Windows NT4, and MS Active Directory in more recent times, may seem - modern and progressive today, but sooner or later something better will replace them. The current - preoccupation with extended identity management solutions and with directories is not unexpected. - The day will come that these too will be evaluated, and what may seem refreshing and powerful may - be better recogized as the chilly winds of the night. To argue against progress is unthinkable, - no matter what may lie ahead. - </p><p> - The development of Samba is moving forwards. The changes since Samba 3.0.0 are amazing, yet many - users would like to see more and faster progress. The benefits of recent developments can be realized - quickly, but documentation is necessary to unlock the pandoras' box. It is our hope that this book - will help the network administrator to rapidly deploy the new features with minimum effort. As you - deploy and gain mileage from the new enablement, take the time to think through what may lie ahead. - Above all, take stock of the freedom of choice that Samba provides in your world, and enjoy the new - potential for seamless interoperability. - </p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="index.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="pr02.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">The Official Samba 3.5.x HOWTO and Reference Guide </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Attribution</td></tr></table></div></body></html> diff --git a/docs/htmldocs/Samba3-HOWTO/pr02.html b/docs/htmldocs/Samba3-HOWTO/pr02.html deleted file mode 100644 index 151f6382dd..0000000000 --- a/docs/htmldocs/Samba3-HOWTO/pr02.html +++ /dev/null @@ -1,95 +0,0 @@ -<html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Attribution</title><link rel="stylesheet" href="../samba.css" type="text/css"><meta name="generator" content="DocBook XSL Stylesheets V1.75.2"><link rel="home" href="index.html" title="The Official Samba 3.5.x HOWTO and Reference Guide"><link rel="up" href="index.html" title="The Official Samba 3.5.x HOWTO and Reference Guide"><link rel="prev" href="pr01.html" title="About the Cover Artwork"><link rel="next" href="pr03.html" title="Foreword"></head><body bgcolor="white" text="black" link="#0000FF" vlink="#840084" alink="#0000FF"><div class="navheader"><table width="100%" summary="Navigation header"><tr><th colspan="3" align="center">Attribution</th></tr><tr><td width="20%" align="left"><a accesskey="p" href="pr01.html">Prev</a> </td><th width="60%" align="center"> </th><td width="20%" align="right"> <a accesskey="n" href="pr03.html">Next</a></td></tr></table><hr></div><div class="preface" title="Attribution"><div class="titlepage"><div><div><h2 class="title"><a name="id281836"></a>Attribution</h2></div></div></div><p><a class="link" href="install.html" title="Chapter 1.

A conversation with John provided some of the rationale, and he left it to me to fill in the -<span class="emphasis"><em>rest</em></span> of the story. So, if you are willing to endure a little bit of background, I will -provide the part of the story that John wouldn't provide. -</p><p> -I am the Director of Corporate Standards at Sun Microsystems, and manage Sun's standards portfolio. Before -that, I was the Director of Standards at Netscape, which was when I met John. Before Sun, there was Digital -Equipment Corporation, also standards. I've written several books on standards, and tend to observe (and -occasionally help) the technical and business trends that drive standardization as a discipline. I tend to see -standardization as a management tool, not as a technical discipline and this is part of the rationale that -John provided. -</p><p> -The book that you have before you focuses on a particular standardized way of doing something hence, it is a -book about a standard. The most important thing to keep in mind about a standard is the rationale for its -creation. Standards are created not for technical reasons, not for business reasons, but for a deeper and much -more compelling reason. Standards are created and used to allow people to communicate in a meaningful way. -Every standard, if it is a true standard, has as its entire (and only) goal set the increasing of relevant -communication between people. -</p><p> -This primary goal cannot be met however, unless the standard is documented. I have been involved in too many -standardization efforts when it became apparent that <span class="emphasis"><em>everybody knows</em></span> was the dominant -emotion of those providing documentation. <span class="emphasis"><em>They</em></span> of the ever present <span class="emphasis"><em>they -say</em></span> and <span class="emphasis"><em>they know</em></span> are the bane of good standards. If <span class="emphasis"><em>they -know</em></span>, why are you doing a standard? -</p><p> -A <span class="emphasis"><em>good standard</em></span> survives because people know how to use it. People know how to use a -standard when it is so transparent, so obvious, and so easy that it becomes invisible. And a standard becomes -invisible only when the documentation describing how to deploy it is clear, unambiguous, and correct. These -three elements must be present for a standard to be useful, allowing communication and interaction between two -separate and distinct entities to occur without obvious effort. As you read this book, look for the evidence -of these three characteristics and notice how they are seamlessly woven into John's text. Clarity and -unambiguity without <span class="emphasis"><em>correctness</em></span> provide a technical nightmare. Correctness and clarity -with ambiguity create <span class="emphasis"><em>maybe bits,</em></span> and correctness and unambiguity without clarity provide -a <span class="emphasis"><em>muddle through</em></span> scenario. -</p><p> -And this is <span class="emphasis"><em>the rest of the story</em></span> that John couldn't (or wouldn't) bring himself to -state. This book provides a clear, concise, unambiguous, and technically valid presentation of Samba to make -it useful to a user to someone who wants to use the standard to increase communication and the capability -for communication between two or more entities whether person-machine, machine-machine, or person-person. -The intent of this book is not to convince anyone of any agenda political, technical, or social. The intent -is to provide documentation for users who need to know about Samba, how to use it, and how to get on with -their primary responsibilities. While there is pride on John's part because of the tremendous success of -the Samba documentation, he writes for the person who needs a tool to accomplish a particular job, and who has -selected Samba to be that tool. -</p><p> -The book is a monument to John's perseverance and dedication to Samba and in my opinion to the goal of -standardization. By writing this book, John has provided the users of Samba those that want to deploy it to -make things better a clear, easy, and ultimately valuable resource. Additionally, he has increased the -understanding and utility of a highly useful standard, and for this, as much as for the documentation, he is -owed a debt of gratitude by those of us who rely on standards to make our lives more manageable. -</p><p> -</p><table border="0" summary="Simple list" class="simplelist"><tr><td>Carl Cargill, Senior Director</td></tr><tr><td>Corporate Standardization, The Office of the CTO</td></tr><tr><td>Sun Microsystems</td></tr></table><p> -</p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="pr02.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="TOSHpreface.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Attribution </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Preface</td></tr></table></div></body></html> diff --git a/docs/htmldocs/Samba3-HOWTO/problems.html b/docs/htmldocs/Samba3-HOWTO/problems.html deleted file mode 100644 index d2e2399cdc..0000000000 --- a/docs/htmldocs/Samba3-HOWTO/problems.html +++ /dev/null @@ -1,174 +0,0 @@ -<html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Chapter 39.

A -Samba-3 PDC can operate with an LDAP account backend. The LDAP backend can be either a common master LDAP -server or a slave server. The use of a slave LDAP server has the benefit that when the master is down, clients -may still be able to log onto the network. This effectively gives Samba a high degree of scalability and is -an effective solution for large organizations. If you use an LDAP slave server for a PDC, you will need to -ensure the master's continued availability if the slave finds its master down at the wrong time, -you will have stability and operational problems. -</p><p> -<a class="indexterm" name="id336971"></a> -<a class="indexterm" name="id336980"></a> -<a class="indexterm" name="id336989"></a> -<a class="indexterm" name="id336998"></a> -While it is possible to run a Samba-3 BDC with a non-LDAP backend, that backend must allow some form of -"two-way" propagation of changes from the BDC to the master. At this time only LDAP delivers the capability -to propagate identity database changes from the BDC to the PDC. The BDC can use a slave LDAP server, while it -is preferable for the PDC to use as its primary an LDAP master server. -</p><p> -<a class="indexterm" name="id337011"></a> -<a class="indexterm" name="id337020"></a> -<a class="indexterm" name="id337030"></a> -<a class="indexterm" name="id337041"></a> -<a class="indexterm" name="id337048"></a> -<a class="indexterm" name="id337054"></a> -<a class="indexterm" name="id337061"></a> -The use of a non-LDAP backend SAM database is particularly problematic because domain member -servers and workstations periodically change the Machine Trust Account password. The new -password is then stored only locally. This means that in the absence of a centrally stored -accounts database (such as that provided with an LDAP-based solution) if Samba-3 is running -as a BDC, the BDC instance of the domain member trust account password will not reach the -PDC (master) copy of the SAM.

Many companies have implemented SSO -solutions. The mode of implementation of a single sign-on solution is an important factor in the practice of -networking in general, and is critical in respect of Windows networking. A company may have a wide variety of -information systems, each of which requires a form of user authentication and validation, thus it is not -uncommon that users may need to remember more than ten login IDs and passwords. This problem is compounded -when the password for each system must be changed at regular intervals, and particularly so where password -uniqueness and history limits are applied. -</p><p> -<a class="indexterm" name="id333428"></a> -There is a broadly held perception that SSO is the answer to the problem of users having to deal with too many -information system access credentials (username/password pairs). Many elaborate schemes have been devised to -make it possible to deliver a user-friendly SSO solution. The trouble is that if this implementation is not -done correctly, the site may end up paying dearly by way of complexity and management overheads. Simply put, -many SSO solutions are an administrative nightmare. -</p><p> -<a class="indexterm" name="id333442"></a> -<a class="indexterm" name="id333449"></a> -<a class="indexterm" name="id333456"></a> -SSO implementations utilize centralization of all user account information. Depending on environmental -complexity and the age of the systems over which a SSO solution is implemented, it may not be possible to -change the solution architecture so as to accommodate a new identity management and user authentication system. -Many SSO solutions involving legacy systems consist of a new super-structure that handles authentication on -behalf of the user. The software that gets layered over the old system may simply implement a proxy -authentication system. This means that the addition of SSO increases over-all information systems complexity. -Ideally, the implementation of SSO should reduce complexity and reduce administative overheads. -</p><p> -<a class="indexterm" name="id333472"></a> -<a class="indexterm" name="id333479"></a> -<a class="indexterm" name="id333488"></a> -<a class="indexterm" name="id333497"></a> -<a class="indexterm" name="id333504"></a> -The initial goal of many network administrators is often to create and use a centralized identity management -system. It is often assumed that such a centralized system will use a single authentication infrastructure -that can be used by all information systems. The Microsoft Windows NT4 security domain architecture and the -Micrsoft active directory service are often put forward as the ideal foundation for such a system. It is -conceptually simple to install an external authentication agent on each of the disparate infromation systems -that can then use the Microsoft (NT4 domain or ads service) for user authentication and access control. The -wonderful dream of a single centralized authentication service is commonly broken when realities are realized. -The problem with legacy systems is often the inability to externalize the authentication and access control -system it uses because its implementation will be excessively invasive from a re-engineering perspective, or -because application software has built-in dependencies on particular elements of the way user authentication -and access control were designed and built. -</p><p> -<a class="indexterm" name="id333524"></a> -<a class="indexterm" name="id333531"></a> -<a class="indexterm" name="id333537"></a> -<a class="indexterm" name="id333544"></a> -<a class="indexterm" name="id333551"></a> -<a class="indexterm" name="id333558"></a> -<a class="indexterm" name="id333565"></a> -<a class="indexterm" name="id333572"></a> -Over the past decade an industry has been developed around the various methods that have been built to get -around the key limitations of legacy information technology systems. One approach that is often used involves -the use of a meta-directory. The meta-directory stores user credentials for all disparate information systems -in the format that is particular to each system. An elaborate set of management procedures is coupled with a -rigidly enforced work-flow protocol for managing user rights and privileges within the maze of systems that -are provisioned by the new infrastructure makes possible user access to all systems using a single set of user -credentials. -</p><p> -<a class="indexterm" name="id333587"></a> -<a class="indexterm" name="id333597"></a> -<a class="indexterm" name="id333606"></a> -<a class="indexterm" name="id333615"></a> -The Organization for the Advancement of Structured Information Standards (OASIS) has developed the Security -Assertion Markup Language (SAML), a structured method for communication of authentication information. The -over-all umbrella name for the technologies and methods that deploy SAML is called Federated Identity -Management (FIM). FIM depends on each system in the complex maze of disparate information systems to -authenticate their respective users and vouch for secure access to the services each provides. -</p><p> -<a class="indexterm" name="id333630"></a> -<a class="indexterm" name="id333639"></a> -<a class="indexterm" name="id333646"></a> -<a class="indexterm" name="id333653"></a> -<a class="indexterm" name="id333659"></a> -<a class="indexterm" name="id333665"></a> -SAML documents can be wrapped in a Simple Object Access Protocol (SOAP) message for the computer-to-computer -communications needed for Web services. Or they may be passed between Web servers of federated organizations -that share live services. The Liberty Alliance, an industry group formed to promote federated-identity -standards, has adopted SAML 1.1 as part of its application framework. Microsoft and IBM have proposed an -alternative specification called WS-Security. Some believe that the competing technologies and methods may -converge when the SAML 2.0 standard is introduced. A few Web access-management products support SAML today, -but implementation of the technology mostly requires customization to integrate applications and develop user -interfaces. In a nutshell, that is why FIM is a big and growing industry. -</p><p> -<a class="indexterm" name="id333687"></a> -<a class="indexterm" name="id333694"></a> -<a class="indexterm" name="id333701"></a> -<a class="indexterm" name="id333708"></a> -<a class="indexterm" name="id333714"></a> -Ignoring the bigger picture, which is beyond the scope of this book, the migration of all user and group -management to a centralized system is a step in the right direction. It is essential for interoperability -reasons to locate the identity management system data in a directory such as Microsoft Active Directory -Service (ADS), or any proprietary or open source system that provides a standard protocol for information -access (such as LDAP) and that can be coupled with a flexible array of authentication mechanisms (such as -kerberos) that use the protocols that are defined by the various general security service application -programming interface (GSSAPI) services. -</p><p> -<a class="indexterm" name="id333733"></a> -<a class="indexterm" name="id333740"></a> -<a class="indexterm" name="id333746"></a> -A growing number of companies provide authentication agents for disparate legacy platforms to permit the use -of LDAP systems.

Samba plus LDAP provides a similar opportunity for extension of a -centralized authentication architecture, but it is the fact that the Samba Team are pro-active in introducing -the extension of authentication services, using LDAP or otherwise, to applications such as SQUID (the open -source proxy server) through tools such as the <code class="literal">ntlm_auth</code> utility, that does much to create -sustainable choice and competition in the FIM market place. -</p><p> -<a class="indexterm" name="id333814"></a> -<a class="indexterm" name="id333821"></a> -<a class="indexterm" name="id333828"></a> -Primary domain control, if it is to be scalable to meet the needs of large sites, must therefore be capable of -using LDAP.

The BDC is biased to answer logon requests in preference to the PDC. On a network segment that has -a BDC and a PDC, the BDC will most likely service network logon requests. The PDC will answer network logon -requests when the BDC is too busy (high load). When a user logs onto a Windows domain member client the -workstation will query the network to locate the nearest network logon server. Where a WINS server is used, -this is done via a query to the WINS server. If a netlogon server can not be found from the WINS query, or in -the absence of a WINS server, the workstation will perform a NetBIOS name lookup via a mailslot broadcast over -the UDP broadcast protocol.

Domain -and server mode security are really just a variation on SMB user-level security. -</p><p> -<a class="indexterm" name="id336157"></a> -<a class="indexterm" name="id336164"></a> -<a class="indexterm" name="id336171"></a> -<a class="indexterm" name="id336177"></a> -<a class="indexterm" name="id336184"></a> -<a class="indexterm" name="id336191"></a> -<a class="indexterm" name="id336198"></a> -Actually, this issue is also closely tied to the debate on whether Samba must be the DMB for its workgroup -when operating as a domain controller. In a pure Microsoft Windows NT domain, the PDC wins the election to be -the DMB, and then registers the DOMAIN<1B> NetBIOS name. This is not the name used by Windows clients -to locate the domain controller, all domain controllers register the DOMAIN<1C> name and Windows clients -locate a network logon server by seraching for the DOMAIN<1C> name. A DMB is a Domain Master Browser - see <a class="link" href="NetworkBrowsing.html" title="Chapter 10. Network Browsing">The Network Browsing Chapter</a>, <a class="link" href="NetworkBrowsing.html#DMB" title="Configuring Workgroup Browsing">Configuring WORKGROUP Browsing</a>; Microsoft PDCs expect to win the election to become the -DMB, if it loses that election it will report a continuous and rapid sequence of warning messages to its -Windows event logger complaining that it has lost the election to become a DMB. For this reason, in networks -where a Samba server is the PDC it is wise to configure the Samba domain controller as the DMB. -</p><div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> -<a class="indexterm" name="id336238"></a> -<a class="indexterm" name="id336245"></a> -<a class="indexterm" name="id336251"></a> -<a class="indexterm" name="id336258"></a> -<a class="indexterm" name="id336265"></a> -SMB/CIFS servers that register the DOMAIN<1C> name do so because they provide the network logon -service. Server that register the DOMAIN<1B> name are DMBs meaning that they are responsible -for browse list synchronization across all machines that have registered the DOMAIN<1D> name. The later -are LMBs that have the responsibility to listen to all NetBIOS name registrations that occur locally to their -own network segment. The network logon service (NETLOGON) is germane to domain control and has nothing to do -with network browsing and browse list management. The 1C and 1B/1D name services are orthogonal to each -other. -</p></div><p> -Now back to the issue of configuring a Samba domain controller to use a mode other than <a class="link" href="smb.conf.5.html#SECURITY" target="_top">security = user</a>. If a Samba host is configured to use another SMB server or domain -controller in order to validate user connection requests, it is a fact that some other machine on the network -(the <a class="link" href="smb.conf.5.html#PASSWORDSERVER" target="_top">password server</a>) knows more about the user than the Samba host. About 99 percent -of the time, this other host is a domain controller. Now to operate in domain mode security, the -<a class="link" href="smb.conf.5.html#WORKGROUP" target="_top">workgroup</a> parameter must be set to the name of the Windows NT domain (which already -has a domain controller). If the domain does not already have a domain controller, you do not yet have a -domain. -</p><p> -Configuring a Samba box as a domain controller for a domain that already by definition has a -PDC is asking for trouble.

Not all computers use the same charset (there are charsets -with German umlauts, Japanese characters, and so on). The American Standard Code -for Information Interchange (ASCII) encoding system has been the normative character -encoding scheme used by computers to date. This employs a charset that contains -256 characters. Using this mode of encoding, each character takes exactly one byte. -</p><p> -<a class="indexterm" name="id432618"></a> -<a class="indexterm" name="id432624"></a> -There are also charsets that support extended characters, but those need at least -twice as much storage space as does ASCII encoding. Such charsets can contain -<code class="literal">256 * 256 = 65536</code> characters, which is more than all possible -characters one could think of. They are called multibyte charsets because they use -more then one byte to store one character. -</p><p> -<a class="indexterm" name="id432643"></a> -One standardized multibyte charset encoding scheme is known as -<a class="ulink" href="http://www.unicode.org/" target="_top">unicode</a>.

However, there is no support for -negotiating the charset to be used in the SMB/CIFS protocol.

To use Shift_JIS series on these platforms, - Japanese filenames created from Windows can be referred to also on - UNIX.</p><p> - If your UNIX is already working with Shift_JIS and there is a user - who needs to use Japanese filenames written from Windows, the - Shift_JIS series is the best choice. However, broken filenames - may be displayed, and some commands that cannot handle non-ASCII - filenames may be aborted during parsing filenames. Especially, there - may be <span class="quote">“<span class="quote">\ (0x5c)</span>”</span> in filenames, which need to be handled carefully. - It is best to not touch filenames written from Windows on UNIX. - </p><p> - Note that most Japanized free software actually works with EUC-JP - only. It is good practice to verify that the Japanized free software can work - with Shift_JIS. - </p></dd><dt><span class="term">EUC-JP series</span></dt><dd><p> -<a class="indexterm" name="id433138"></a> -<a class="indexterm" name="id433145"></a> - EUC-JP series means a locale that is equivalent to the industry - standard called EUC-JP, widely used in Japanese UNIX (although EUC - contains specifications for languages other than Japanese, such as - EUC-KR). In the case of EUC-JP series, for example, if a Japanese - filename consists of 0x8ba4 and 0x974c and <span class="quote">“<span class="quote">.txt</span>”</span> is written from - Windows on Samba, the filename on UNIX becomes 0xb6a6, 0xcdad, - <span class="quote">“<span class="quote">.txt</span>”</span> (an 8-byte BINARY string). - </p><p> -<a class="indexterm" name="id433166"></a> -<a class="indexterm" name="id433172"></a> -<a class="indexterm" name="id433179"></a> -<a class="indexterm" name="id433186"></a> -<a class="indexterm" name="id433193"></a> -<a class="indexterm" name="id433200"></a> -<a class="indexterm" name="id433206"></a> -<a class="indexterm" name="id433213"></a> -<a class="indexterm" name="id433220"></a> -<a class="indexterm" name="id433227"></a> - Since EUC-JP is usually used on open source UNIX, Linux, and FreeBSD, and on commercial-based UNIX, Solaris, - IRIX, and Tru64 UNIX as Japanese locale (however, it is also possible on Solaris to use Shift_JIS and UTF-8, - and on Tru64 UNIX it is possible to use Shift_JIS). To use EUC-JP series, most Japanese filenames created from - Windows can be referred to also on UNIX. Also, most Japanized free software works mainly with EUC-JP only. - </p><p> - It is recommended to choose EUC-JP series when using Japanese filenames on UNIX. - </p><p> - Although there is no character that needs to be carefully treated - like <span class="quote">“<span class="quote">\ (0x5c)</span>”</span>, broken filenames may be displayed and some - commands that cannot handle non-ASCII filenames may be aborted - during parsing filenames. - </p><p> -<a class="indexterm" name="id433254"></a> - Moreover, if you built Samba using differently installed libiconv, - the eucJP-ms locale included in libiconv and EUC-JP series locale - included in the operating system may not be compatible. In this case, you may need to - avoid using incompatible characters for filenames. - </p></dd><dt><span class="term">UTF-8</span></dt><dd><p> - UTF-8 means a locale equivalent to UTF-8, the international standard defined by the Unicode consortium. In - UTF-8, a <em class="parameter"><code>character</code></em> is expressed using 1 to 3 bytes. In case of the Japanese language, - most characters are expressed using 3 bytes. Since on Windows Shift_JIS, where a character is expressed with 1 - or 2 bytes is used to express Japanese, basically a byte length of a UTF-8 string the length of the UTF-8 - string is 1.5 times that of the original Shift_JIS string. In the case of UTF-8, for example, if a Japanese - filename consists of 0x8ba4 and 0x974c, and <span class="quote">“<span class="quote">.txt</span>”</span> is written from Windows on Samba, the filename - on UNIX becomes 0xe585, 0xb1e6, 0x9c89, <span class="quote">“<span class="quote">.txt</span>”</span> (a 10-byte BINARY string). - </p><p> - For systems where iconv() is not available or where iconv()'s locales - are not compatible with Windows, UTF-8 is the only locale available. - </p><p> - There are no systems that use UTF-8 as the default locale for Japanese. - </p><p> - Some broken filenames may be displayed, and some commands that - cannot handle non-ASCII filenames may be aborted during parsing - filenames. Especially, there may be <span class="quote">“<span class="quote">\ (0x5c)</span>”</span> in filenames, which - must be handled carefully, so you had better not touch filenames - written from Windows on UNIX. - </p><p> -<a class="indexterm" name="id433314"></a> -<a class="indexterm" name="id433321"></a> -<a class="indexterm" name="id433328"></a> - In addition, although it is not directly concerned with Samba, since - there is a delicate difference between the iconv() function, which is - generally used on UNIX, and the functions used on other platforms, - such as Windows and Java, so far is concerns the conversion between - Shift_JIS and Unicode UTF-8 must be done with care and recognition - of the limitations involved in the process. - </p><p> -<a class="indexterm" name="id433341"></a> - Although Mac OS X uses UTF-8 as its encoding method for filenames, - it uses an extended UTF-8 specification that Samba cannot handle, so - UTF-8 locale is not available for Mac OS X. - </p></dd><dt><span class="term">Shift_JIS series + vfs_cap (CAP encoding)</span></dt><dd><p> -<a class="indexterm" name="id433361"></a> -<a class="indexterm" name="id433367"></a> -<a class="indexterm" name="id433374"></a> - CAP encoding means a specification used in CAP and NetAtalk, file - server software for Macintosh. In the case of CAP encoding, for - example, if a Japanese filename consists of 0x8ba4 and 0x974c, and - <span class="quote">“<span class="quote">.txt</span>”</span> is written from Windows on Samba, the filename on UNIX - becomes <span class="quote">“<span class="quote">:8b:a4:97L.txt</span>”</span> (a 14 bytes ASCII string). - </p><p> - For CAP encoding, a byte that cannot be expressed as an ASCII - character (0x80 or above) is encoded in an <span class="quote">“<span class="quote">:xx</span>”</span> form. You need to take - care of containing a <span class="quote">“<span class="quote">\(0x5c)</span>”</span> in a filename, but filenames are not - broken in a system that cannot handle non-ASCII filenames. - </p><p> - The greatest merit of CAP encoding is the compatibility of encoding - filenames with CAP or NetAtalk. These are respectively the Columbia Appletalk - Protocol, and the NetAtalk Open Source software project. - Since these software applications write a file name on UNIX with CAP encoding, if a - directory is shared with both Samba and NetAtalk, you need to use - CAP encoding to avoid non-ASCII filenames from being broken. - </p><p> - However, recently, NetAtalk has been - patched on some systems to write filenames with EUC-JP (e.g., Japanese original Vine Linux). - In this case, you need to choose EUC-JP series instead of CAP encoding. - </p><p> - vfs_cap itself is available for non-Shift_JIS series locales for - systems that cannot handle non-ASCII characters or systems that - share files with NetAtalk. - </p><p> - To use CAP encoding on Samba-3, you should use the unix charset parameter and VFS - as in <a class="link" href="unicode.html#vfscap-intl" title="Example 30.1.

This fact has - made it difficult to integrate the two systems in a satisfactory - manner.</p><p> -<a class="indexterm" name="id417602"></a> -<a class="indexterm" name="id417609"></a> - One common solution in use today has been to create - identically named user accounts on both the UNIX and Windows systems - and use the Samba suite of programs to provide file and print services - between the two. This solution is far from perfect, however, because - adding and deleting users on both sets of machines becomes a chore, - and two sets of passwords are required both of which - can lead to synchronization problems between the UNIX and Windows - systems and confusion for users.</p><p>We divide the unified logon problem for UNIX machines into - three smaller problems:</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>Obtaining Windows NT user and group information. - </p></li><li class="listitem"><p>Authenticating Windows NT users. - </p></li><li class="listitem"><p>Password changing for Windows NT users. - </p></li></ul></div><p> -<a class="indexterm" name="id417648"></a> -<a class="indexterm" name="id417654"></a> - Ideally, a prospective solution to the unified logon problem - would satisfy all the above components without duplication of - information on the UNIX machines and without creating additional - tasks for the system administrator when maintaining users and - groups on either system. The Winbind system provides a simple - and elegant solution to all three components of the unified logon - problem.</p></div><div class="sect1" title="What Winbind Provides"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id417666"></a>What Winbind Provides</h2></div></div></div><p> -<a class="indexterm" name="id417674"></a> -<a class="indexterm" name="id417681"></a> -<a class="indexterm" name="id417688"></a> -<a class="indexterm" name="id417695"></a> - Winbind unifies UNIX and Windows NT account management by - allowing a UNIX box to become a full member of an NT domain. Once - this is done, the UNIX box will see NT users and groups as if - they were <span class="quote">“<span class="quote">native</span>”</span> UNIX users and groups, allowing the NT domain - to be used in much the same manner that NIS+ is used within - UNIX-only environments.</p><p> -<a class="indexterm" name="id417711"></a> -<a class="indexterm" name="id417718"></a> -<a class="indexterm" name="id417725"></a> -<a class="indexterm" name="id417731"></a> - The end result is that whenever a - program on the UNIX machine asks the operating system to look up - a user or group name, the query will be resolved by asking the - NT domain controller for the specified domain to do the lookup. - Because Winbind hooks into the operating system at a low level - (via the NSS name resolution modules in the C library), this - redirection to the NT domain controller is completely - transparent.</p><p> -<a class="indexterm" name="id417745"></a> -<a class="indexterm" name="id417752"></a> - Users on the UNIX machine can then use NT user and group - names as they would <span class="quote">“<span class="quote">native</span>”</span> UNIX names. They can chown files - so they are owned by NT domain users or even login to the - UNIX machine and run a UNIX X Window session as a domain user.</p><p> -<a class="indexterm" name="id417768"></a> - The only obvious indication that Winbind is being used is - that user and group names take the form <code class="constant">DOMAIN\user</code> and - <code class="constant">DOMAIN\group</code>. This is necessary because it allows Winbind to determine - that redirection to a domain controller is wanted for a particular - lookup and which trusted domain is being referenced.</p><p> -<a class="indexterm" name="id417787"></a> -<a class="indexterm" name="id417794"></a> - Additionally, Winbind provides an authentication service that hooks into the PAM system - to provide authentication via an NT domain to any PAM-enabled - applications.

This system is used for most network-related operations - between Windows NT machines, including remote management, user authentication, and print spooling. Although - initially this work was done to aid the implementation of Primary Domain Controller (PDC) functionality in - Samba, it has also yielded a body of code that can be used for other purposes. - </p><p> -<a class="indexterm" name="id418056"></a> -<a class="indexterm" name="id418063"></a> -<a class="indexterm" name="id418069"></a> - Winbind uses various MSRPC calls to enumerate domain users and groups and to obtain detailed information about - individual users or groups. Other MSRPC calls can be used to authenticate NT domain users and to change user - passwords. By directly querying a Windows PDC for user and group information, Winbind maps the NT account - information onto UNIX user and group names. - </p></div><div class="sect2" title="Microsoft Active Directory Services"><div class="titlepage"><div><div><h3 class="title"><a name="id418082"></a>Microsoft Active Directory Services</h3></div></div></div><p> -<a class="indexterm" name="id418090"></a> -<a class="indexterm" name="id418096"></a> -<a class="indexterm" name="id418103"></a> -<a class="indexterm" name="id418110"></a> - Since late 2001, Samba has gained the ability to interact with Microsoft Windows 2000 using its <span class="quote">“<span class="quote">native - mode</span>”</span> protocols rather than the NT4 RPC services. Using LDAP and Kerberos, a domain member running - Winbind can enumerate users and groups in exactly the same way as a Windows 200x client would, and in so doing - provide a much more efficient and effective Winbind implementation. - </p></div><div class="sect2" title="Name Service Switch"><div class="titlepage"><div><div><h3 class="title"><a name="id418126"></a>Name Service Switch</h3></div></div></div><p> -<a class="indexterm" name="id418134"></a> -<a class="indexterm" name="id418140"></a> -<a class="indexterm" name="id418147"></a> -<a class="indexterm" name="id418153"></a> - The NSS is a feature that is present in many UNIX operating systems. It allows system - information such as hostnames, mail aliases, and user information - to be resolved from different sources. For example, a standalone - UNIX workstation may resolve system information from a series of - flat files stored on the local file system. A networked workstation - may first attempt to resolve system information from local files, - and then consult an NIS database for user information or a DNS server - for hostname information.</p><p> -<a class="indexterm" name="id418168"></a> -<a class="indexterm" name="id418174"></a> -<a class="indexterm" name="id418181"></a> -<a class="indexterm" name="id418188"></a> -<a class="indexterm" name="id418195"></a> - The NSS application programming interface allows Winbind to present itself as a source of system - information when resolving UNIX usernames and groups. Winbind uses this interface and information obtained - from a Windows NT server using MSRPC calls to provide a new source of account enumeration. Using standard UNIX - library calls, you can enumerate the users and groups on a UNIX machine running Winbind and see all users and - groups in an NT domain plus any trusted domain as though they were local users and groups. - </p><p> -<a class="indexterm" name="id418209"></a> -<a class="indexterm" name="id418216"></a> -<a class="indexterm" name="id418222"></a> - The primary control file for NSS is <code class="filename">/etc/nsswitch.conf</code>. When a UNIX application - makes a request to do a lookup, the C library looks in <code class="filename">/etc/nsswitch.conf</code> for a line that - matches the service type being requested; for example, the <span class="quote">“<span class="quote">passwd</span>”</span> service type is used when - user or group names are looked up.

With a PAM - module, it is possible to specify different authentication methods for different system applications without - having to recompile these applications. PAM is also useful for implementing a particular policy for - authorization. For example, a system administrator may only allow console logins from users stored in the - local password file but only allow users resolved from an NIS database to log in over the network. - </p><p> -<a class="indexterm" name="id418380"></a> -<a class="indexterm" name="id418387"></a> -<a class="indexterm" name="id418394"></a> -<a class="indexterm" name="id418400"></a> -<a class="indexterm" name="id418407"></a> - Winbind uses the authentication management and password management PAM interface to integrate Windows - NT users into a UNIX system. This allows Windows NT users to log in to a UNIX machine and be authenticated - against a suitable PDC. These users can also change their passwords and have this change take effect directly - on the PDC. - </p><p> -<a class="indexterm" name="id418420"></a> -<a class="indexterm" name="id418426"></a> -<a class="indexterm" name="id418433"></a> -<a class="indexterm" name="id418440"></a> - PAM is configured by providing control files in the directory <code class="filename">/etc/pam.d/</code> for - each of the services that require authentication. When an authentication request is made by an application, - the PAM code in the C library looks up this control file to determine what modules to load to do the - authentication check and in what order. This interface makes adding a new authentication service for Winbind - very easy: simply copy the <code class="filename">pam_winbind.so</code> module to <code class="filename">/lib/security/</code>, - and the PAM control files for relevant services are updated to allow authentication via Winbind.

This is slightly different from UNIX, which has a range of numbers that are used to identify users and - the same range used to identify groups. It is Winbind's job to convert RIDs to UNIX ID numbers and vice versa. - When Winbind is configured, it is given part of the UNIX user ID space and a part of the UNIX group ID space - in which to store Windows NT users and groups. If a Windows NT user is resolved for the first time, it is - allocated the next UNIX ID from the range. The same process applies for Windows NT groups.

To reduce the network - cost of these lookups, Winbind uses a caching scheme based on the SAM sequence number supplied by NT domain - controllers. User or group information returned by a PDC is cached by Winbind along with a sequence number - also returned by the PDC. This sequence number is incremented by Windows NT whenever any user or group - information is modified. If a cached entry has expired, the sequence number is requested from the PDC and - compared against the sequence number of the cached entry. If the sequence numbers do not match, then the - cached information is discarded and up-to-date information is requested directly from the PDC. - </p></div></div><div class="sect1" title="Installation and Configuration"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id418597"></a>Installation and Configuration</h2></div></div></div><div class="sect2" title="Introduction"><div class="titlepage"><div><div><h3 class="title"><a name="id418602"></a>Introduction</h3></div></div></div><p> -<a class="indexterm" name="id418610"></a> -<a class="indexterm" name="id418617"></a> -<a class="indexterm" name="id418624"></a> -This section describes the procedures used to get Winbind up and running.

The section name is the name of the shared resource and the parameters within the - section define the shares attributes. - </p><p> - There are three special sections, [global], [homes] and [printers], which are described under - <span class="emphasis"><em>special sections</em></span>. The following notes apply to ordinary section descriptions. - </p><p> - A share consists of a directory to which access is being given plus a description of the access rights - which are granted to the user of the service. Some housekeeping options are also specifiable. - </p><p> - Sections are either file share services (used by the client as an extension of their native file systems) - or printable services (used by the client to access print services on the host running the server). - </p><p> - Sections may be designated <span class="emphasis"><em>guest</em></span> services, in which case no password is required to - access them. A specified UNIX <span class="emphasis"><em>guest account</em></span> is used to define access privileges in this - case. - </p><p> - Sections other than guest services will require a password to access them. The client provides the - username. As older clients only provide passwords and not usernames, you may specify a list of usernames to - check against the password using the <code class="literal">user =</code> option in the share definition. For modern clients - such as Windows 95/98/ME/NT/2000, this should not be necessary. - </p><p> - The access rights granted by the server are masked by the access rights granted to the specified or guest - UNIX user by the host system. The server does not grant more access than the host system grants. - </p><p> - The following sample section defines a file space share. The user has write access to the path <code class="filename">/home/bar</code>. The share is accessed via the share name <code class="literal">foo</code>: -</p><pre class="programlisting"> - <em class="parameter"><code>[foo]</code></em> - <a class="link" href="smb.conf.5.html#PATH" target="_top">path = /home/bar</a> - <a class="link" href="smb.conf.5.html#READONLY" target="_top">read only = no</a> -</pre><p> - </p><p> - The following sample section defines a printable share. The share is read-only, but printable. That is, - the only write access permitted is via calls to open, write to and close a spool file. The <span class="emphasis"><em>guest - ok</em></span> parameter means access will be permitted as the default guest user (specified elsewhere): -</p><pre class="programlisting"> - <em class="parameter"><code>[aprinter]</code></em> - <a class="link" href="smb.conf.5.html#PATH" target="_top">path = /usr/spool/public</a> - <a class="link" href="smb.conf.5.html#READONLY" target="_top">read only = yes</a> - <a class="link" href="smb.conf.5.html#PRINTABLE" target="_top">printable = yes</a> - <a class="link" href="smb.conf.5.html#GUESTOK" target="_top">guest ok = yes</a> -</pre><p> - </p></div><div class="refsect1" title="SPECIAL SECTIONS"><a name="id265955"></a><h2>SPECIAL SECTIONS</h2><div class="refsect2" title="The [global] section"><a name="id265960"></a><h3>The [global] section</h3><p> - Parameters in this section apply to the server as a whole, or are defaults for sections that do not - specifically define certain items.

If a match is found, it is - used. If no match is found, the requested section name is treated as a username and looked up in the local - password file. If the name exists and the correct password has been given, a share is created by cloning the - [homes] section. - </p><p> - Some modifications are then made to the newly created share: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p> - The share name is changed from homes to the located username. - </p></li><li class="listitem"><p> - If no path was given, the path is set to the user's home directory. - </p></li></ul></div><p> - If you decide to use a <span class="emphasis"><em>path =</em></span> line in your [homes] section, it may be useful - to use the %S macro. For example: -</p><pre class="programlisting"> -<strong class="userinput"><code>path = /data/pchome/%S</code></strong> -</pre><p> - is useful if you have different home directories for your PCs than for UNIX access. - </p><p> - This is a fast and simple way to give a large number of clients access to their home directories with a minimum - of fuss. - </p><p> - A similar process occurs if the requested section name is <span class="quote">“<span class="quote">homes</span>”</span>, except that the share - name is not changed to that of the requesting user. This method of using the [homes] section works well if - different users share a client PC. - </p><p> - The [homes] section can specify all the parameters a normal service section can specify, though some make more sense - than others. The following is a typical and suitable [homes] section: -</p><pre class="programlisting"> -<em class="parameter"><code>[homes]</code></em> -<a class="link" href="smb.conf.5.html#READONLY" target="_top">read only = no</a> -</pre><p> - </p><p> - An important point is that if guest access is specified in the [homes] section, all home directories will be - visible to all clients <span class="emphasis"><em>without a password</em></span>. In the very unlikely event that this is actually - desirable, it is wise to also specify <span class="emphasis"><em>read only access</em></span>. - </p><p> - The <span class="emphasis"><em>browseable</em></span> flag for auto home directories will be inherited from the global browseable - flag, not the [homes] browseable flag. This is useful as it means setting <span class="emphasis"><em>browseable = no</em></span> in - the [homes] section will hide the [homes] share but make any auto home directories visible. - </p></div><div class="refsect2" title="The [printers] section"><a name="PRINTERSSECT"></a><h3>The [printers] section</h3><p> - This section works like [homes], but for printers. - </p><p> - If a [printers] section occurs in the configuration file, users are able to connect to any printer - specified in the local host's printcap file. - </p><p> - When a connection request is made, the existing sections are scanned. If a match is found, it is used. - If no match is found, but a [homes] section exists, it is used as described above. Otherwise, the requested - section name is treated as a printer name and the appropriate printcap file is scanned to see if the requested - section name is a valid printer share name. If a match is found, a new printer share is created by cloning the - [printers] section. - </p><p> - A few modifications are then made to the newly created share: - </p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem"><p>The share name is set to the located printer name</p></li><li class="listitem"><p>If no printer name was given, the printer name is set to the located printer name</p></li><li class="listitem"><p>If the share does not permit guest access and no username was given, the username is set - to the located printer name.</p></li></ul></div><p> - The [printers] service MUST be printable - if you specify otherwise, the server will refuse - to load the configuration file. - </p><p> - Typically the path specified is that of a world-writeable spool directory with the sticky bit set on - it.

This is a file - consisting of one or more lines like this: -</p><pre class="programlisting"> -alias|alias|alias|alias... -</pre><p> - </p><p> - Each alias should be an acceptable printer name for your printing subsystem. In the [global] section, - specify the new file as your printcap. The server will only recognize names found in your pseudo-printcap, - which of course can contain whatever aliases you like. The same technique could be used simply to limit access - to a subset of your local printers. - </p><p> - An alias, by the way, is defined as any component of the first entry of a printcap record.

The most common is to map usernames that users use on DOS or Windows - machines to those that the UNIX box uses. The other is to map multiple users to a single username so that they - can more easily share files. - </p><p> - Please note that for user or share mode security, the username map is applied prior to validating the user - credentials. Domain member servers (domain or ads) apply the username map after the user has been - successfully authenticated by the domain controller and require fully qualified enties in the map table (e.g. - biddle = <code class="literal">DOMAIN\foo</code>). - </p><p> - The map file is parsed line by line. Each line should contain a single UNIX username on the left then a '=' - followed by a list of usernames on the right. The list of usernames on the right may contain names of the form - @group in which case they will match any UNIX username in that group. The special client name '*' is a - wildcard and matches any name. Each line of the map file may be up to 1023 characters long. - </p><p> - The file is processed on each line by taking the supplied username and comparing it with each username on the - right hand side of the '=' signs. If the supplied name matches any of the names on the right hand side then it - is replaced with the name on the left. Processing then continues with the next line. - </p><p> - If any line begins with a '#' or a ';' then it is ignored. - </p><p> - If any line begins with an '!' then the processing will stop after that line if a mapping was done by the - line. Otherwise mapping continues with every line being processed. Using '!' is most useful when you have a - wildcard mapping line later in the file. - </p><p> - For example to map from the name <code class="constant">admin</code> or <code class="constant">administrator</code> to the UNIX - name <code class="constant"> root</code> you would use: -</p><pre class="programlisting"> -<code class="literal">root = admin administrator</code> -</pre><p> - Or to map anyone in the UNIX group <code class="constant">system</code> to the UNIX name <code class="constant">sys</code> you would use: -</p><pre class="programlisting"> -<code class="literal">sys = @system</code> -</pre><p> - </p><p> - You can have as many mappings as you like in a username map file. - </p><p> - If your system supports the NIS NETGROUP option then the netgroup database is checked before the <code class="filename">/etc/group </code> database for matching groups. - </p><p> - You can map Windows usernames that have spaces in them by using double quotes around the name. For example: -</p><pre class="programlisting"> -<code class="literal">tridge = "Andrew Tridgell"</code> -</pre><p> - would map the windows username "Andrew Tridgell" to the unix username "tridge". - </p><p> - The following example would map mary and fred to the unix user sys, and map the rest to guest. Note the use of the - '!' to tell Samba to stop processing if it gets a match on that line: -</p><pre class="programlisting"> -!sys = mary fred -guest = * -</pre><p> - </p><p> - Note that the remapping is applied to all occurrences of usernames. Thus if you connect to \\server\fred and - <code class="constant">fred</code> is remapped to <code class="constant">mary</code> then you will actually be connecting to - \\server\mary and will need to supply a password suitable for <code class="constant">mary</code> not - <code class="constant">fred</code>. The only exception to this is the username passed to the <a class="link" href="smb.conf.5.html#PASSWORDSERVER" target="_top">password server</a> (if you have one). The password server will receive whatever username the client - supplies without modification. - </p><p> - Also note that no reverse mapping is done. The main effect this has is with printing. Users who have been - mapped may have trouble deleting print jobs as PrintManager under WfWg will think they don't own the print - job. - </p><p> - Samba versions prior to 3.0.8 would only support reading the fully qualified username - (e.g.: <code class="literal">DOMAIN\user</code>) from - the username map when performing a kerberos login from a client. However, when looking up a map entry for a - user authenticated by NTLM[SSP], only the login name would be used for matches. This resulted in inconsistent - behavior sometimes even on the same server. - </p><p> - The following functionality is obeyed in version 3.0.8 and later: - </p><p> - When performing local authentication, the username map is applied to the login name before attempting to authenticate - the connection. - </p><p> - When relying upon a external domain controller for validating authentication requests, smbd will apply the username map - to the fully qualified username (i.e. <code class="literal">DOMAIN\user</code>) only after the user has been successfully authenticated. - </p><p> - An example of use is: -</p><pre class="programlisting"> -username map = /usr/local/samba/lib/users.map -</pre><p> - </p><p>Default: <span class="emphasis"><em><em class="parameter"><code>username map</code></em> = <code class="literal"> -# no username map</code> -</em></span> -</p></dd></dl></div></div><div class="section" title="user"><div class="titlepage"><div><div><h3 class="title"><a name="id337402"></a> - -<a name="USER"></a>user -</h3></div></div></div><a class="indexterm" name="id337403"></a><div class="variablelist"><dl><dt></dt><dd><p>This parameter is a synonym for <a class="link" href="#USERNAME">username</a>.</p></dd></dl></div></div><div class="section" title="users"><div class="titlepage"><div><div><h3 class="title"><a name="id337433"></a> - -<a name="USERS"></a>users -</h3></div></div></div><a class="indexterm" name="id337434"></a><div class="variablelist"><dl><dt></dt><dd><p>This parameter is a synonym for <a class="link" href="#USERNAME">username</a>.</p></dd></dl></div></div><div class="section" title="username (S)"><div class="titlepage"><div><div><h3 class="title"><a name="id337465"></a> - -username (S) -</h3></div></div></div><a class="indexterm" name="id337466"></a><a name="USERNAME"></a><div class="variablelist"><dl><dt></dt><dd><p>Multiple users may be specified in a comma-delimited - list, in which case the supplied password will be tested against - each username in turn (left to right).</p><p>The deprecated <em class="parameter"><code>username</code></em> line is needed only when - the PC is unable to supply its own username.

A pthread pool is created - which expands dynamically by creating new threads as work is - given to it to a maximum of 100 threads per smbd process. - To change this limit see the "aio num threads" parameter - below. New threads are not created if idle threads are - available when a new read or write request is received, - the new work is given to an existing idle thread. Threads - terminate themselves if idle for one second. - </p><p> - Note that the smb.conf parameters <code class="literal">aio read size</code> - and <code class="literal">aio write size</code> must also be set appropriately - for this module to be active. - </p><p>This module MUST be listed last in any module stack as - the Samba VFS pread/pwrite interface is not thread-safe.
