  ****************************************************************
  A CICS signon drives DFHUSAD add_user processing. The userid
  already exists in the user directory, and DFHXSPW and DFHXSSB
  are called in turn to action the request. DFHXSSB issues an
  INQUIRE_PASSWORD_DATA call which returns exception with reason
  APPLID_NOTAUTH, as the userid is not authorized to the CICS
  application. Message ICH408I is issued to report the error.
  The xssb_applid_notauth condition is passed back as
  xspw_applid_notauth. However DFHUSAD does not recognize
  xspw_applid_notauth and sets usad_response to usad_disaster. A
  system dump, message DFHUS0002 and *EXC trace result.

  US 0309 USAD  *EXC* Exception-unknown

  The CICS signon fails with message DFHUS0002 A severe error
  (code X'0309') has occurred in module DFHUSAD.

  xspw_applid_notauth condition.
