Recipe 17.9 Delegating Control of Managing an Application Partition

17.9.1 Problem

You want to delegate control over the management of an application partition.

17.9.2 Solution

17.9.2.1 Using a graphical user interface
  1. Open ADSI Edit.

  2. Connect to the Configuration naming context of the forest the application partition is in if it is not already present in the left pane.

  3. Expand the Configuration naming context and click on the Partitions container.

  4. In the right pane, right-click on the crossRef object that represents the application partition and select Properties.

  5. Click the Security tab.

  6. Click the Advanced button.

  7. Click the Add button.

  8. Use the object picker to find the user or group you want to delegate control to and click OK.

  9. Click the Properties tab.

  10. Under Allow, check the boxes beside Write msDS-NC-Replica-Locations, Write msDS-SDReferenceDomain, Write msDS-Replication-Notify-First-DSA-Delay, and Write msDS-Replication-Notify-Subsequent-DSA-Delay.

  11. Click OK.

17.9.3 Discussion

If you want to delegate control of management of application partitions, you must grant control over four key attributes. Here is a description of each attribute and what can be accomplished by having control over it:

msDS-NC-Replica-Locations

By having write access to this attribute, a user can add replica servers for the application partition. See Recipe 17.3 for more information.

msDS-SDReferenceDomain

By having write access to this attribute, a user can define the default security descriptor domain for the application partition. See Recipe 17.8 for more information.

msDS-Replication-Notify-First-DSA-Delay

See Recipe 17.7 for more information.

msDS-Replication-Notify-Subsequent-DSA-Delay

See Recipe 17.7 for more information.

If you want to delegate control over managing objects within the application partition, you need to follow the same procedures you would when delegating control over objects in a domain naming context. See Recipe 14.5 for more information on delegating control.
