samba - Jun 2004 - failed login, NT_STATUS_PASSWORD_MUST_CHANGE

Hi,

I am unable to login to a samba system that uses
kerberos  to authenticate to ADS if the users password
has expired on the ADS system or if "User must change
password at next login" is checked on the ADS..  I get
a "login incorrect" message on the linux system and 
the log file gives the following error:

pam_winbind[3647]: request failed: Must change
password, PAM error was 12, NT error was
NT_STATUS_PASSWORD_MUST_CHANGE

pam_winbind[3647]: user `blah' new password required  
  Jun 17 10:25:53 samba1 login[3647]: FAILED LOGIN
SESSION FROM /dev/tty1 FOR blah, Authentication token
is no longer valid; new one required.                 
 

Is it possible for the user to get prompted to change
their password at login?  I am very new to the
Microsoft integration and any advice would be greatly
appreciated.

Note: getent passwd, wbinfo -u, wbinfo -g, and logging
into the samba system with a ADS user account that
hasn't expired or must change password at first login
works great without any issues.

My configuration is as follows:

Suse 8.1 2.4.19-4
