Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Applications where the short username is sourced from an LDAP
    repository.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The queue manager was retrieving a shortname from the LDAP
    repository, and was adding this to the MQMD.UserIdentifier,
    padding to the right with null bytes.  Instead it should have
    padded to the right with blanks (ie. byte 0x20 in ASCII code
    pages).
    

Problem conclusion

  • The MQ code has been corrected so that MQMD.UserIdentifer is
    padded to the right with blanks, not null bytes.
