Auto Zone does not provide zone-specific features

If you decide to use Auto Zone, you should keep in mind that Auto Zone does not support any zone-specific features, such as the ability to define rights and roles, assign roles to users and groups, configure auditing, or keep legacy identity attributes on different computers.

If you want to configure role-based access rights, delegate administrative activity, or migrate existing users and groups, you should not use Auto Zone. If you have a large Active Directory forest, but only require automatic profile generation for a subset of users and groups, you might want to use a combination of hierarchical zone and Auto Zone.
