The user who creates a zone has full control over zone properties and administrative tasks. Only the zone owner can delegate administrative tasks to other users and groups through the Zone Delegation Wizard. In most cases, the users who are allowed to create zones have domain administrator privileges and sufficient permissions to perform all administrative tasks and to delegate administrative tasks to other users.
If you manually set permissions to allow domain users to create zones, however, you should also manually set the permissions to allow those users to manage rights and roles or notify zone administrators that they should run the Zone Delegation Wizard and assign those tasks to their own account or to appropriate users and groups. At least one administrator must have permission to add an authorization store, define rights and roles, and manage role assignments in each zone. All users must have at least one valid role assignment to access a zone.
