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

[Ankur5 C]

ok , great i will use guest as default user and pass.

This is my rabbit config file :

[{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,     <<"guest">>},
                  {default_pass,     <<"guest">>},
                  {allow_anonymous,  true},
                  {vhost,            <<"/">>},
                  {subscription_ttl, 1800000},
                  {prefetch,         10},
                  {ssl_listeners,    [8883]},
                  {tcp_listeners,    [1883]},
                  {tcp_listen_options, [binary,
                                        {packet,    raw},
                                        {reuseaddr, true},
                                        {backlog,   128},
                                        {nodelay,   true}]}]}
].

Please let me know where should I provide the loopback_users ?

You can configure MQTT plugin to not perform authentication as 
authentication
is optional in MQTT:
http://www.rabbitmq.com/mqtt.html

If you ask me, this is a terrible MQTT feature (and in fact
I know that some MQTT-based services reject unauthenticated clients).
But if you use default_user and default_pass, you do not need to provide
any credentials. That's why default_user/default_pass are there.

Again, this is pretty clearly documented in 
http://www.rabbitmq.com/mqtt.html.
