3.5. Enable Broker-to-Broker Authentication in A-MQ

To enable authentication between 2 brokers, for example 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.
To configure the network connector follow the below instructions:
  • Assuming that Broker A is configured to connect to Broker B. Configure the Broker A's networkConnector element with username/password credentials as shown:
  • For example, the following settings would enable basic encryption using the MD5 message digest algorithm: 
    <beans>
  <broker>
    <networkConnectors>
      <networkConnector name="BrokerABridge" userName="user" password="password" uri="static://(ssl://brokerA:61616)"/>
    </networkConnectors>
  </broker>
</beans>
    Here 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.
The encryption settings in the org.apache.karaf.jaas.cfg file are applied only to the default karaf realm in a standalone container.
