No worries, we were all new to it at one time or another.

Ok, so if you're passing the token in the username of the AMQP login then you really just need to change the 'q' function back to what Simon had. As you've prepended {ticket, Username} to the head of the list of auth properties, the original q function should create ?ticket="ticket" just as you want.

Well I can't say whether or not the design makes any sense I'm afraid, as I don't know enough about your application or its requirements, but it does sound like a reasonable approach from what you've said so far. I suspect there is a bit more to implementing a custom auth provider that you need to do besides logging in however, so you might find the complexity grows as you work on it.
