Identify recursive groups
Groups can be members of other groups. Active Directory allows "children" to become "parents" within their own family tree. If the nested group structure loops in a circular way group membership assignments become ineffective and nonsensical. Through these recursions or circular nested groups every user who is a member of any of the recursive groups is granted all of the access rights of all of the groups. The consequence is a confusing mess of excessive access rights. ARM automatically identifies all recursions in your system. We highly recommend removing the recursion by breaking the chain of circular group memberships.
Administer only with ARM and recursions can no longer happen because ARM does not allow the creation of recursions.
The deeper your group structure the more likely you are to have circular nested group structures. We therefore recommend keeping an eye on the number of nested group levels.
