HP UX Red Hat Direry Server Software manual Chaining Ldap Controls Using the Console

Chapter 3. Configuring Directory Databases

•Managed DSA. This controls returns smart referrals as entries, rather than following the referral, so the smart referral itself can be changed or deleted.

•Loop detection. This control keeps track of the number of times the server chains with another server. When the count reaches the configured number, a loop is detected, and the client application is notified. For more information about using this control, see Section 3.7.5, “Detecting Loops”.

NOTE

Server-side sorting and VLV controls are supported only when a client application request is made to a single database. Database links cannot support these controls when a client application makes a request to multiple databases.

The Select control OIDs to add dialog box displays. Select the OID of a control to add to the list, and click OK.

4.To delete a control from the list, select it from the LDAP controls forwarded to the remote server list, and click Delete.

3.1.2.2. Chaining LDAP Controls from the Command-Line

Alter the controls that the database link forwards by changing the nsTransmittedControls attribute of the cn=config,cn=chaining database, cn=plugins,cn=config entry. For example, to forward the virtual list view control, add the following to the database link entry in the configuration file:

nsTransmittedControls: 2.16.840.1.113730.3.4.9

In addition, if clients of the Directory Server create their own controls and their operations should to be chained to remote servers, add the OID of the custom control to the nsTransmittedControls attribute.
