[Samba] User Must Change Password On Next Logon

[Eyal M]

Hi,

I currently have samba as a pdc and I'm trying to find out how to make 'User
must change password on....' works.
As domain admin I check that box in the User Proerties, but when the user
log-in, nothing happends.
I saw that with pdbedit -lv <user> there is a line saying: Password must
change: Mon, 18 Jan 2038 21:14:07 GMT there is any way to change this?

thanks in advance,
Eyal.
