Personally I don't really see how this is working myself. I am not the one who set up the servers so maybe they did something out of the ordinary. In workgroup manager I have made myself a member of several groups. Group1 is a group called test it's group ID is 21 and it has no group folder, Group2 is IMS with a group ID is 1030 also no group folder, next is Group3 named FirthGrade GID is 1047 and it does have a group folder. Group4 is called Herald GID 1042 also has a group folder. Now if I belong to just IMS and test I have no problem thus supporting what you have said, also if I add the Herald or FifthGrade groups seperatly no problem. As soon as they are both there together I am forced to choose which one I want to use. The real interesting part is on the list of accounts to pick it only shows the two with group folders, no Test or IMS, but if I add another group called graphics that has no group folder it is added to the list of accounts I can choose.
