Error description
An MQ Client application used a CLNTCONN channel with a client-side exit to connect to queue manager with CONNAUTH enabled, CHLAUTH enabled, and the qm.ini setting ChlAuthEarlyAdopt=Y set. The client passed an MQCSP structure with no userid and the connection failed (as expected) with the error: = = = = = = = = = = = = = = = = = = = = AMQ9777: Channel was blocked The inbound channel '' was blocked from address '' because the active values of the channel matched a record configured with USERSRC(NOACCESS). The active values of the channel were 'CLNTUSER('mqm'). = = = = = = = = = = = = = = = = = = = = The connection *should* have failed in this way but no client user value had been passed so the CLNTUSER value was incorrect. It should have read: "CLNTUSER()"
Local fix
