AH, something just went 'ping' ;-)

There was a recent Debian bug, the bug being that the 'passwd' and
'group' lines in /etc/nsswitch.conf had been setup as 'winbind compat',
I couldn't understand why anybody would want to do that, I think you
may have just given me a reason.

When (on a Unix machine) you ask for a users ID, NSS is consulted and
this uses /etc/nsswitch.conf to find the users ID. Normally the local
files are search first and if you are searching for 'nobody' on Debian,
you get back '65534', winbind is not consulted. However if the order of
searching is switched around and winbind is used before the local
files, then you will get the user mapped by winbind to whoever you have
in smb.conf and the ID for this user returned.

This is what I think will happen, never tried it myself, but I will.
