ABL authentication callbacks allow you to:

  • Extend or modify the built-in authentication systems where OpenEdge performs the user authentication (_oeusertable, _oslocal)
  • Extend an SSO-only authentication system, including the built-in _extsso or a user-defined authentication system that is not enabled for OpenEdge-performed user authentication
  • Design and implement a user-defined authentication system that is enabled for OpenEdge-performed user authentication
