  PROBLEM DESCRIPTION:
  A defect in error handling when modifying the user caused
  unexpected FDC records and also failures in reporting error
  message to the user if the command is executed against a
  non-existent user.
  
  This issue was introduced due to a logic error in the code
  change for APAR IT38979.
  

Problem conclusion

  and also to report an error to the user if the command is
  executed against a non-existent user.
