Error description

  • If authentication fails with the ChlauthEarlyAdopt=y parameter

    appears in the queue manager error log files:

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of IBM MQ with queue managers configured with the
    "ChlauthEarlyAdopt=y" setting.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When using the ChlauthEarlyAdopt setting, the authentication
    process occurs before the MQCONN process when the application
    name is flowed over the connection. Accordingly, the application
    name was blank when inserted into the message.
    

Problem conclusion

  • When ChlauthEarlyAdopt is enabled, the application context at
    the point where the message is issued is the channel process
    (typically amqrmppa). To allow users to differentiate these
    errors from errors caused by locally-bound applications, if a
    more specific remote application name has not yet been supplied,
    the channel process name will now be displayed in this message
    instead of a blank string:
    
    AMQ5534: User ID '<userid>' authentication failed
    
    EXPLANATION:
    The user ID and password supplied by the 'amqrmppa' program
    could not be authenticated.
