No I remember now.  Local and aliases are the same
category on a PDC.

I see now.  However for simplicity sake, would it be better
to fix the domain member group mapping code and use that
to implement this.

For example, assume that a samaba member server sets 
up the following mapping table

	sysadmin	  : "Domain Administrators"
	students, faculty : "Domain Users"

Now if this were a member server as I said, the
right hand side would be valid group names on
the PDC.  

If this were configured on a Samba PDC, then the
mapping simply presents a rename, but I like the idea
of being able to map multiple UNIX groups
to a single domain group.  Only groups listed
are considered to be domain groups.  All other in
/etc/group or NIS are ignored.

Now for another point of clarification, is it the case
that local groups on a Samba PDC are useless and will
never be referenced?

Preach the truth! :-)
