Samba4 currently embed its own Winbind implementation. Winbind is responsible for affecting an unix uid to user, gid to groups.
 
 
It is also used to list groups of a given user, to translate SID to uid/gid and many other things.
 
  
As soon as you use file server capabilities of Samba4 (for instance for serving GPO or login scripts), calls to Winbind will be made to get the user's uid (and allocate if none exists).

For setting up Winbindd a Samba Active Directory (AD) domain controller (DC), see:
This can be noticed by the fact that when a file is created from Windows in one of the samba4 server share you will see big numerical uid and gid.

For example:  
 
<pre>
 
ls /home/mat/workspace/samba/homematwsnet/sysvol/home.matws.net/Policies/\{085C0631-6142-4637-9FED-2EC5B4FB6952\}/ -l

The user interaction can be eased by the usage <tt>libnss_winbind</tt>. That's the point of the next paragraph.
 
 
 
== Using libnss_winbind ==
 
=== Installing ===
 
 
 
The current installation process put the library libnss_winbind.so in <tt>&lt;PATH_TO_SAMBA&gt;/lib</tt> (ie. <tt>/usr/local/samba/lib</tt>).
 
 
 
This library has to be installed in /lib to allow the system to be able to use it, it also needs a symlink to make it completely work:
 
 
 
<pre>ln -s /lib/libnss_winbind.so /lib/libnss_winbind.so.2</pre>
 
 
 
Finally you need to instruct the system to use the nss winbind library when searching for users or groups. For this add the keywork <tt>winbind</tt> to the stanza passwd and group in <tt>/etc/nsswitch.conf</tt>.
 
 
 
It should look like:
 
<pre>
 
passwd:          files winbind
 
group:          files winbind
 
shadow:          files
 
...
 
</pre>
 
 
 
<u>Note:</u> On some systems it is the keyword compat that is used instead of files.
