[rabbitmq-discuss] MQTT login failed for "guest" access_refused even after mentioning loopback_users

[Ankur5 C]

Also sharing my client code : Do I need to use any user name and password
at the client end?

try {

			client = new MqttClient(
"tcp://ec2-54-179-77-171.ap-southeast-1.compute.amazonaws.com:1883",
"AmazonTest");

			client.connect();

			System.out.println("Connection status :: "+client
.isConnected());

			int i=0;
			MqttMessage message = new MqttMessage();
			while(true){
				try {
					i++;
					Thread.sleep(1000);
					message.setPayload(("Hii I am Raspberry
PI!!!"+Integer.toString(i)).getBytes());
					client.publish("Raspberry/test", message);
				} catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}


		} catch (MqttException e) {
			e.printStackTrace();
		}
	}

[{rabbit,        [{tcp_listeners,    [5672]},{ssl_listeners, [5671]},
			{ssl_options,
[{cacertfile,"/etc/rabbitmq/testca/cacert.pem"},
                    {certfile,"/etc/rabbitmq/server/cert.pem"},
                    {keyfile,"/etc/rabbitmq/server/key.pem"},
                    {verify,verify_peer},
			{fail_if_no_peer_cert,false}]}]},
 {rabbitmq_mqtt, [{default_user,     <<"cto">>},
                  {default_pass,     <<"cto">>},
			{allow_anonymous,  true},
                  {vhost,            <<"/">>},
                  {subscription_ttl, 1800000},
                  {prefetch,         10},
                  {ssl_listeners,    [8883]},
                  {tcp_listeners,    [1883]},
                  {tcp_listen_options, [binary,
                                        {packet,    raw},
                                        {reuseaddr, true},

loopback_users is a RabbitMQ server config setting, not the MQTT plugin.

The example on http://www.rabbitmq.com/access-control.html includes it in
the "rabbit" app config.

It is also highly recommended to use a new user with non-obvious
credentials
rather than enabling remote access for "guest".
