About Winbind and Samba4

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). 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:

ls /home/mat/workspace/samba/homematwsnet/sysvol/\{085C0631-6142-4637-9FED-2EC5B4FB6952\}/ -l
