Error description

  • After configuring a queue manager's CONNAUTH/AUTHINFO to work
    with LDAP (IDPWLDAP).
    
    The queue manager successfully connects to LDAP, DISPLAY
    QMSTATUS LDAPCONN shows as CONNECTED.
    
    After a few seconds, the QMSTATUS LDAPCONN changes to ERROR.
    
    At about the same time, the queue manager's error log does show
    user authentication error occurred:
    
    AMQ5534E: User ID 'myuser' authentication failed
    EXPLANATION:
    The user ID and password supplied by the 'myprogram' program
    could not be authenticated.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who view the DISPLAY QMSTATUS command and look at the
    LDAPCONN output.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    Whenever a user/password authentication attempt failed (eg.
    because the password had been typed wrongly), the LDAPCONN
    status was changed to ERROR.
    
    This is not correct, because the LDAP connection was still
    healthy - there was no need to mark it as in-error just because
    a user/password check returned not-authorized.
    

Problem conclusion

  • The MQ code has been corrected to ensure that the LDAPCONN
    status is not changed to ERROR when normal activities, such as
    checking a user's password, fail.
    
    Additional text will be added to the Knowledge Center to explain
    that the LDAPCONN status within DISPLAY QMSTATUS is a single
    status for the whole queue manager, reflecting only the most
    recent actions performed with the LDAP server.  There are
    multiple connections to the LDAP server, one per queue manager
    agent process.  LDAPCONN reflects the status from the most
    recent LDAP connection across the agents of the whole queue
    manager.  If the error is temporary, and quickly clears, then
    the ERROR status will be short-lived.  Always look in the queue
    manager error logs to see more details of any LDAP connectivity
    failures.
