Enable Password Change on Expiration

Hi I have a few users who connect via winscp only. We have enabled password expiration after regular time periods. How do I enable a notification for these users and enable them to change their passwords using the winscp GUI without command line or putty?

Any help is appreciated.[/list]

WinSCP supports SSH password change request:

Some servers also use keyboard interactive prompt to enforce password change, which is also supported by WinSCP:
