samba - Mar 2003 - winbind and NT must change password at next logon.

How do I configure samba / winbind & pam to allow a user to change their
password if the "change password at next logon password"
is set?

I am trying to intergrate a number of samba boxes (2.2.7a) into an existing
Windows NT domain.

What I really want to happen is the same as loging in on a windows box i.e. xdm
logon via pam, if the users
password needs to be changed a requester is displayed.

Is this possible?
