Fix show-stopper for 3.2. Smbd depends on group SID

Browse Source 
position zero being the primary group sid. Authenicating
via winbindd call returned a non-sorted sid list. This
fixes is for both a winbindd call and a pac list from
an info3 struct. Without this we mess up the
primary group associated with created files. Found by
Herb.
