samba - Jun 2008 - builtin group, domain group, or local group

Hi,
I'm using smbldap-groupadd to add groups for my PDC, and the default 
group type is domain group. The problem is, if I do an ldapsearch of 
groups created in this fashion, I don't see the memberUid's of the users
that belong to this group.

if I don't use the default, I can do an ldapsearch of the group and see 
a list of members of the group.

Any ideas which sambaGroupType I should use? It seems puzzling to me 
that if you use the default, there's no way to see who's a member and 
who's not.


Thanks,
Chris
