 From section 2.2.4 of the AMQP 0-9-1 spec:
<quote>
There is no hand-shaking for errors on connections that are not fully 
open. Following successful protocol header negotiation, which is defined 
in detail later, and prior to sending or receiving Open or Open-Ok, a 
peer that detects an error MUST close the socket without sending any 
further data.

In other words, an authentication failure will result in the connection 
getting closed by the server, without it sending any error to the client.

Matthias.
