Hi,

I able to connect to the broker using different clients with the same
username/password combination (mqttjs with node.js and mosquito_pub/sub),
but not using mosquitto Python library.
I use mosquitto  1.1.3 on Python 2.7 on Ubuntu 10.04.

I get rc=4 (CONNACK_REFUSED_BAD_USERNAME_PASSWORD) in on_connect method:

The code looks like this:

...
    def __init__(self):
        client_id = "%s_%s" % (__file__, os.urandom(4).encode("hex"))
        log("client_id = %s" % client_id)
        self.shutdown = False
        self.client = mosquitto.Mosquitto(client_id=client_id,
clean_session=True)
        self.client.username_pw_set('uername', 'password')
        self.client.on_connect = self.on_connect
        self.client.connect('localhost', 1883, keepalive=25)
        log("connect done")
        try:
            while True:
                self.client.loop(1000)
        except:
            self.client.disconnect()
            self.shutdown = True;

    def on_connect(self, client, obj, rc):
        log("on_connect rc=%d" % rc)
        # TODO - handle cases rc!=0 - i.e. connect errors
        if rc == 0:
            self.publish_thread =
threading.Thread(target=self.do_publish_thread)
            self.publish_thread.start()
...

Any ideas?

Thanks in advance,
Zvi
