The rank attribute on the config element is tied to the ranking of the underlying OSGi service. When the JAAS framework performs an authentication, it will use the realm name to find a matching JAAS configuration. If multiple configurations are used, the one with the highest rank attribute will be used. So if you want to override the default security configuration in Karaf (which is used by the ssh shell, web console and JMX layer), you need to deploy a JAAS configuration with the name name="karaf" and rank="1".
