Description

Currently, when AMQP 1.0 link attach triggers an ACL error in the C++ broker, the broker first confirms the attach with correct source & target and afterwards it detaches the link with the ACL error. That makes the client think that the link was first properly opened and only later closed.

Instead of this, the broker should response to the attach with refusing the link - sending back an attach with source/target set to null. That would make it more clear to the client that an immediate detach should be expected. This mechanism is already used when the attach`s source/target doesn't exist.
