(though it doesn't actually attempt to verify users in the PLAIN case in 
anyway) as seen here in the ConnectionStart. The client should then be 
able to choose PLAIN without issue (as seen in the following 

What is the interaction you are seeing here? What platform are you 
running the broker on?
