I'm not a RabbitMQ expert, but you might also want to add information
like  (from appropriate hosts)

    $ rabbitmqctl status

to the bug.

If it's a test environment, you can try addint the user manually, maybe:

    $ sudo rabbitmqctl add_user {username} {password}

Ensure it's added correctly:

    $ sudo rabbitmqctl list_users

I remember once having to do that a while ago.
