When I set up my accounts in Snow Leopard Server, I was able to give an explicit group id to my user-defined groups using the old Workgroup Manager. Now that I've updated to Mountain Lion Server, I miss that precise control.
Here is my problem: I created the following groups and group ids in OS X 10.6 Server
1025 - myteam
1026 - workgroup
1027 - theAteam
9000 - zombiesquad
9001 - hoboes
When I migrated to OS X 10.8 with the new Server app, my groups and group ids have all been scrambled:
1025 - workgroup
1026 - myteam
1027 - theAteam
1028 - zombiesquad
1029 - hoboes
How do I go about setting the groups and group ids back to their prior assignment?
