The relationship only works when:
I add the AD user "UserA" directly to the bundle
I add the AD usergroup wich contains the user "UserA" to the bundle
I add the AD folder above the user "UserA" to the bundle

The following does not work:
user "UserA" is in usergroup "departmentAA".
usergroup "departmentAA" is in usergroup "departmentA"
The bundle is assigned to usergroup "DepartmentA"

Why am I able to use the AD folder above the user and not the usergroup "DepartmentA"?
