If you are deploying your brokers in a cluster configuration, and one or more of the brokers is configured to require authentication, then it is necessary to equip all of the brokers in the cluster with the appropriate credentials, so that they can all talk to each other.
Given two brokers, Broker A and Broker B, where Broker A is configured to perform
authentication, you can configure Broker B to log on to Broker A by setting the
userName
attribute and the password
attribute in the
networkConnector
element, as follows:
<beans ...> <broker ...> ... <networkConnectors> <networkConnector name="BrokerABridge" userName="user" password="password" uri="static://(ssl://brokerA:61616)"/> ... </networkConnectors> ... </broker> </beans>
If Broker A is configured to connect to Broker B, Broker A's
networkConnector
element must also be configured with username/password
credentials, even though Broker B is not configured to perform authentication. Broker A's
authentication plug-in checks for Broker A's username. For example, if Broker A has its
authentication configured by a simpleAuthenticationPlugin
element, Broker A's
username must appears in this element.
