The Name +Service Switch allows user and system information to be obtained from +different databases services such as NIS or DNS. The exact behaviour can +be configured throught the <code>/etc/nsswitch.conf</code> file. Users and groups +are allocated as they are resolved to a range of user and group ids +specified by the administrator of the Samba system. +<p>The service provided by <strong>winbindd</strong> is called `winbind' and can be used to +resolve user and group information from a Windows NT server. +<p>The following nsswitch databases are implemented by the <strong>winbindd</strong> +service: +<p><dl> +<p><p></p><dt><strong>passwd</strong><dd> +<p>User information traditionally stored in the <strong>passwd(5)</strong> file and used by +<strong>getpwent(3)</strong> functions. +<p><p></p><dt><strong>group</strong><dd> +<p>Group information traditionally stored in the <strong>group(5)</strong> file and used by +<strong>getgrent(3)</strong> functions. +<p></dl> +<p>For example, the following simple configuration in the +<code>/etc/nsswitch.conf</code> file can be used to initially resolve user and group +information from <code>/etc/passwd</code> and <code>/etc/group</code> and then from the +Windows NT server. +<p><code>passwd: files winbind</code> +<p><code>group: files winbind</code> +<p><a name="OPTIONS"></a> +<h2>OPTIONS</h2> + +<p>The following options are available to the <strong>winbindd</strong> daemon: +<p><dl> +<p><a name="minusd"></a> +<p></p><dt><strong><strong>-d debuglevel</strong></strong><dd> +Sets the debuglevel to an integer between 0 and 100. 0 is for no debugging +and 100 is for reams and reams. To submit a bug report to the Samba Team, +use debug level 100 (see <strong>BUGS.txt</strong>). +<p><a name="minusi"></a> +<p></p><dt><strong><strong>-i</strong></strong><dd> +Tells winbindd to not become a daemon and detach from the current terminal. +This option is used by developers when interactive debugging of winbindd is +required. +<p></dl> +<p><a name="NAMEANDIDRESOLUTION"></a> +<h2>NAME AND ID RESOLUTION</h2> + +<p>Users and groups on a Windows NT server are assigned a relative id (rid) +which is unique for the domain when the user or group is created. To +convert the Windows NT user or group into a unix user or group, a mapping +between rids and unix user and group ids is required. This is one of the +jobs that <strong>winbindd</strong> performs. +<p>As <strong>winbindd</strong> users and groups are resolved from a server, user and group +ids are allocated from a specified range. This is done on a first come, +first served basis, although all existing users and groups will be mapped +as soon as a client performs a user or group enumeration command. The +allocated unix ids are stored in a database file under the Samba lock +directory and will be remembered. +<p>WARNING: The rid to unix id database is the only location where the user +and group mappings are stored by <strong>winbindd</strong>. If this file is deleted or +corrupted, there is no way for <strong>winbindd</strong> to determine which user and +group ids correspond to Windows NT user and group rids. +<p><a name="CONFIGURATION"></a> +<h2>CONFIGURATION</h2> + +<p>Configuration of the <strong>winbindd</strong> daemon is done through configuration +parameters in the <a href="smb.conf.5.html"><strong>smb.conf</strong></a> file.
