IT22938: AMQ9777 Reports CLNTUSER(mqm) not CLNTUSER(<MCAUSER>) when ChlAuthEarlyAdopt is enabled

APAR status

• Closed as program error.

Error description

• If ChlAuthEarlyAdopt is enabled and an error condition exists
  causing the currently active channel to be blocked, you may see
  a queue manager log entry showing-
  
  AMQ9777: Channel was blocked
  
  EXPLANATION:
  The inbound channel '<ch_name>' was blocked from address
  'localhost (<nnn.n.n.n>)' because the active values of
  the channel matched a record configured with USERSRC
  (NOACCESS). The active values of the channel were
  'CLNTUSER (<some_user>) ADDRESS(localhost)'.
  
  
  When the CLNTUSER value is expected to be <MCAUSER> rather than
  the displayed user name .
