LI73317: STACK DUMP GENERATED IN DB2DIAG.LOG WHEN AN AUTHENTICATION PLUGIN RETURNS BAD LOGIN

APAR status

  • Closed as program error.

Error description

  • When an authentication plugin returns a message for an
    unsuccessful logon, it triggers a stack dump (noted as CALLSTCK)
    in the db2diag.log.  This extra information is normally not
    necessary for a simple "bad password" error.
    
    This APAR will prevent a stack dump when the authentication
    plugin returns a message in the errormsg buffer.
    
    Note, however, that calls to the API function db2secLogMessage
    with the following parameters will continue to cause a stack
    dump:
    
    DB2SEC_LOG_CRITICAL
    DB2SEC_LOG_ERROR
    

Local fix

  • Modify your plugin so that no error messages are returned.  Log
    the bad password attempt with a call to db2secLogMessage with
    DB2SEC_LOG_WARNING as a parameter, which will not cause a stack
    dump.
