[jira] Assigned: (QPID-1896) No-auth Windows broker fails client
connection with "Selected mechanism not supported"

Assignee: Steve Huston
Steve, what do you think about this? Shall I commit the patch to get PLAIN supported on windows when auth=no? Or do you prefer to keep it down to ANONYMOUS in that case (which I accept makes perfect sense)?

> If a client offers any non-empty auth mechanism (e.g., "PLAIN"), the windows C++ broker will fail to start/tune the connection with "Selected mechanism not supported" eventhough it has authorization disabled ("--auth=no").
