RabbitMQ gives a "access refused, login refused for user" error when attempting to follow the celery tutorial

I'm attempting to follow the celery tutorial, but I run into a problem when I run python manage.py celeryd: my RabbitMQ server (installed on a virtual machine on my dev box) won't let my user login.

I get the following on my Django management console:

[ERROR/MainProcess] AMQP Listener: Connection Error: Socket closed. Trying again in 2 seconds...

and this shows up in my rabbit.log file on my RabbitMQ server:

exception on TCP connection <0.5814.0> from $DJANGO_BOX_IP
{channel0_error,starting,{amqp,access_refused,"login refused for user '$CONFIGURED_USER'",'connection.start_ok'}}

I've double-checked my user, permissions, and vhost info, and they all seem to match up. Any help troubleshooting is greatly appreciated.

UPDATE: Following the advice of @asksol I get the following traceback:

Are you running django? If so, then try this:

>>> from carrot.connection import DjangoBrokerConnection
>>> c = DjangoBrokerConnection()
>>> c.connection

Does it give the same thing? Are you sure you're connecting to the right hostname, and that the username and password has access to the virtual host?

UPDATE:

>>> from carrot.connection import DjangoBrokerConnection
>>> c = DjangoBrokerConnection()
>>> for n in ("host", "userid", "password", "virtual_host", "ssl"):
...     print("%s -> %s" % (n, repr(getattr(c, n, None))))

UPDATE: You have to do the above before running c.connection, as the connection is established lazily in carrot.
