Troubleshooting Broker Configuration Directory Communication

The Message Queue broker authenticates clients against the Directory Server that stores the Identity Synchronization for Windows configuration. If the broker cannot connect to this Directory Server, no clients will be able to connect to the Message Queue, and the broker log will mention some javax.naming exception, such as “ javax.naming.CommunicationException” or “javax.naming.NameNotFoundException ”.

If a javax.naming exception occurs, do the following:

• Verify that all imq.user_repository.ldap properties in /var/imq/instances/isw-broker/props/config.properties have the correct values. If any of these is incorrect, stop the Message Queue broker, correct and save the file, and restart the broker. The directory server host name must be resolvable from the broker’s machine.

• Verify that the imq.user_repository.ldap.password property in /etc/imq/passfile is correct.

• In some cases, the broker cannot search for entries if the root suffix contains spaces.
