[Samba] winbindd using FQDN domain name now?

[Adrian Chung]

As of RC3 and RC4, I've noticed that winbindd's wb_getpwuid function
is using the form <FQDN-domain><winbind-seperator><username>, and
before, it was simply <NetBIOS-domain><winbind-seperator><username>.

The net effect of what I'm seeing is that users which have a UNIX
account locally on the samba box and also a domain account are being
authenticated against the AD DC, but their UIDs are getting resolved
to the local UNIX UIDs rather than AD UIDs.

Here's a snippet of the winbind log (level 5) from an XP Home box (not
a domain member):

At this point, I'm authenticated as the UNIX UID and have access via
samba, but smbstatus shows the wrong username (the non-domain user).

Anyone know how I can fix this?
