Use this variable to override the default behavior CESN transaction response for invalid user credentials. Default behavior
               reports "Your userid is invalid" or "Your password is invalid". Setting this variable to any value will cause CESN to produce
               an invalid credential message instead. 
               		
               
Example: 
                  		
               
 
               		ES_CESN_NO_OS390=secured
