Windows Client account password expiry

[Matthew Geddes]

Hi,

If you aren't all on holidays, does anyone know how I can emulate
Windows NT's password expiry on a Samba / Linux box (including the
prompt at login). I am planning on running Samba 2.0.5a and RedHat 6.0.
I also need the user to be able to change their password. If not, does
anybody know of a different method of doing the same?

Thanks,

Matt
