Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQ 7.5 or higher using SET CHLAUTH command.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic error in the queue manager channel authentication record
    lookup code meant that the correct error response was not
    returned in the event that no matching record was found. This
    prevented the generation of an appropriate error message to
    report that the authentication records was not found.
    

Problem conclusion

  • The queue manager channel authentication logic has been
    corrected to return the correct response when no matching record
    is found.
