Problem with User-Created Roster Groups and LDAP Groups

We use ActiveDirectory to manage users and shared groups. However, some of my users would like to be able to have their own groups (say specialties within a department like Level 1 and Level 2 tech support). However, when they try to create their own group, it does not create a permanent one on their roster. both jiveRoster and jiveRosterGroups show no changes.

I can replicate it with a variety of clients, including Spark.
