- functions, depending on whether it is run by the <span class="emphasis"><em>root</em></span> user
- or not. When run as a normal user it allows the user to change
- the password used for their SMB sessions on any machines that store
- SMB passwords. </p><p>By default (when run with no arguments) it will attempt to
- change the current user's SMB password on the local machine. This is
- similar to the way the <code class="literal">passwd(1)</code> program works. <code class="literal">
- smbpasswd</code> differs from how the passwd program works
- however in that it is not <span class="emphasis"><em>setuid root</em></span> but works in
- a client-server mode and communicates with a
- locally running <a class="citerefentry" href="smbd.8.html"><span class="citerefentry"><span class="refentrytitle">smbd</span>(8)</span></a>. As a consequence in order for this to
- succeed the smbd daemon must be running on the local machine. On a
- UNIX machine the encrypted SMB passwords are usually stored in
- the <a class="citerefentry" href="smbpasswd.5.html"><span class="citerefentry"><span class="refentrytitle">smbpasswd</span>(5)</span></a> file. </p><p>When run by an ordinary user with no options, smbpasswd
- will prompt them for their old SMB password and then ask them
- for their new password twice, to ensure that the new password
- was typed correctly. No passwords will be echoed on the screen
- whilst being typed. If you have a blank SMB password (specified by
- the string "NO PASSWORD" in the smbpasswd file) then just press
- the &lt;Enter&gt; key when asked for your old password. </p><p>smbpasswd can also be used by a normal user to change their
- SMB password on remote machines, such as Windows NT Primary Domain
- Controllers. See the (<em class="parameter"><code>-r</code></em>) and <em class="parameter"><code>-U</code></em> options
- below. </p><p>When run by root, smbpasswd allows new users to be added
- and deleted in the smbpasswd file, as well as allows changes to
- the attributes of the user in this file to be made. When run by root, <code class="literal">
- smbpasswd</code> accesses the local smbpasswd file
- directly, thus enabling changes to be made even if smbd is not
- running. </p></div><div class="refsect1" title="OPTIONS"><a name="id265836"></a><h2>OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">-a</span></dt><dd><p>
- This option specifies that the username following should be added to the local smbpasswd file, with the new
