By default, Everyone has Read permission for a CN, and the CN administrator (the person who created the CN) has Full Control permission. With Read permission for a CN, users can retrieve the CN's permissions settings. In other words, users have Get Permissions permissions. Write permission for a CN is identical to Read permission.
You can specify Full Control, Read, Write, or Special Access permissions for all users and groups. You can set the following Special Access permissions for a CN.
