title: RabbitMQ on Openstack Juno
body: <p>I am installing Openstack Juno on Fedora 19. I have deleted RabbitMQ default user "guest" and create a new user named "demo". And in all nova.conf I config rabbit_userid=demo. But connected to localhost:5672 failed. From the rabbitmq log, RabbitMQ still use default user "guest" to connect.I tried to set default_user "demo" in rabbitmq.conf but it doesn't work.Why and how to resolve? 
  Following is the error log:</p>
  
  <blockquote>
    <p>{handshake_error,starting,0,{amqp_error,access_refused, "AMQPLAIN login refused: user 'guest'-    invalid credentials",'connection.start_ok'}}`</p>
  </blockquote>
  
  <p>The content in rabbitmq.conf:</p>
  
  <blockquote>
    <p>[    {rabbit, [{default_pass, [&lt;&lt;"demo">>]}], [{default_user, [&lt;&lt;"demo">>]}]}    ].    </p>
  </blockquote>
