Getting JBAS011360: Unauthorized access ERROR while trying to invoke any MBean operations in JConsole of EAP 6

Issue

• EAP 6.3.1 server configured in domain mode. Trying to connect to a JBoss server running on a different host controller. JMX configuration is as follows:
  domain.xml:

            <subsystem xmlns="urn:jboss:domain:jmx:1.3">
                <expose-resolved-model/>
                <expose-expression-model/>
                <remoting-connector use-management-endpoint="false"/>
            </subsystem>

            <subsystem xmlns="urn:jboss:domain:remoting:1.1">
                <connector name="remoting-connector" socket-binding="remoting" security-realm="JConsole"/>
            </subsystem>

host.xml of the server we're trying to connect to:

          <security-realm name="JConsole">
                <authentication>
                    <local default-user="$local" skip-group-loading="true"/>
                    <properties path="JConsole-users.properties" relative-to="jboss.domain.config.dir"/>
                </authentication>
            </security-realm>

• In the property file, the username/hash for admin:admin is stored. Connecting with JConsole through the JBoss jconsole.sh/jconsole.bat script works with the username/password 'admin:admin' and fails with other combinations (as expected). We are able to see the statistics on memory, classes, etc, as expected. But while trying to invoke mbean operations ( in JConsole 'mbean' tab), we always get the following Unauthorized access ERROR, where as the expected result : as authentication clearly works, I expect to be able to invoke mbean operations.
