Opis

The EXTSEC subsystem parameter specifies whether detailed reason codes are returned to a DRDA client when a DDF connection request fails due to security errors. It is recommended to set the value to NO to return generic error codes to the clients. The detailed error codes can expose the reason for a potential fraudulent logon attempt.
