No option to create objects in of an Active Roles Managed Unit
Active Roles Admins and delegated admins with Create Child Object permissions will not see the option to create objects inside of an Active Roles Managed Unit.
This is expected Active Roles functionality.
A Managed Unit is a view of native Active Directory containers and objects. Objects will need to be created inside of native Active Directory containers. If they meet the rules of one or more Managed Units after they have been created, they will be visible in those Managed Units.
