+ The idmap_tdb2 plugin is a substitute for the default idmap_tdb
+ backend used by winbindd for storing SID/uid/gid mapping tables
+ in clustered environments with Samba and CTDB.
+ </p><p>
+ In contrast to read only backends like idmap_rid, it is an allocating
+ backend: This means that it needs to allocate new user and group IDs in
+ order to create new mappings. The allocator can be provided by the
+ idmap_tdb2 backend itself or by any other allocating backend like
+ idmap_tdb or idmap_ldap. This is configured with the
+ parameter <em class="parameter"><code>idmap alloc backend</code></em>.
+ </p><p>
+ Note that in order for this (or any other allocating) backend to
+ function at all, the default backend needs to be writeable.
+ The ranges used for uid and gid allocation are the default ranges
+ configured by "idmap uid" and "idmap gid".
+ </p><p>
+ Furthermore, since there is only one global allocating backend
+ responsible for all domains using writeable idmap backends,
+ any explicitly configured domain with idmap backend tdb2
+ should have the same range as the default range, since it needs
+ to use the global uid / gid allocator. See the example below.
+ </p></div><div class="refsect1" lang="en"><a name="id2522958"></a><h2>IDMAP OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">range = low - high</span></dt><dd><p>
+ Defines the available matching uid and gid range for which the
+ backend is authoritative.
+ If the parameter is absent, Winbind fails over to use
+ the "idmap uid" and "idmap gid" options
+ from smb.conf.
+ </p></dd></dl></div></div><div class="refsect1" lang="en"><a name="id2483356"></a><h2>IDMAP SCRIPT</h2><p>
+ The tdb2 idmap backend supports a script for performing id mappings
+ through the smb.conf option <em class="parameter"><code>idmap : script</code></em>.
+ The script should accept the following command line options.
+ </p><pre class="programlisting">
+ SIDTOID S-1-xxxx
+ IDTOSID UID xxxx
+ IDTOSID GID xxxx
+ </pre><p>
+ And it should return one of the following responses as a single line of
+ text.
+ </p><pre class="programlisting">
+ UID:yyyy
+ GID:yyyy
+ SID:yyyy
+ ERR:yyyy
+ </pre><p>
+ Note that the script should cover the complete range of SIDs
+ that can be passed in for SID to Unix ID mapping, since otherwise
+ SIDs unmapped by the script might get mapped to IDs that had
+ previously been mapped by the script.
+ </p></div><div class="refsect1" lang="en"><a name="id2483399"></a><h2>EXAMPLES</h2><p>
+ This example shows how tdb2 is used as a the default idmap backend.
+ It configures the idmap range through the global options for all
+ domains encountered. This same range is used for uid/gid allocation.
+ </p><pre class="programlisting">
+ [global]
+ idmap backend = tdb2
+ idmap uid = 1000000-2000000
+ idmap gid = 1000000-2000000
+ </pre></div><div class="refsect1" lang="en"><a name="id2483536"></a><h2>AUTHOR</h2><p>
+ The original Samba software and related utilities
+ were created by Andrew Tridgell. Samba is now developed
+ by the Samba Team as an Open Source project similar
+ to the way the Linux kernel is developed.
