  9. Rem      utlpwdmg.sql - script for Default Password Resource Limits
  10. Rem
  11. Rem    DESCRIPTION
  12. Rem      This is a script for enabling the password management features
  13. Rem      by setting the default password resource limits.
  14. Rem
  15. Rem    NOTES
  16. Rem      This file contains a function for minimum checking of password
  17. Rem      complexity. This is more of a sample function that the customer
  18. Rem      can use to develop the function for actual complexity checks that the
  19. Rem      customer wants to make on the new password.
