[Samba] Wrong message "Your password has expired"

[Juan Miguel Corral]

Hello. I have a Debian Lenny Samba 3.2.5 server, with LDAP backend. On linux clients, I am using pam_winbind to change passwords, so both Samba and LDAP passwords are kept in sync.

When cients are using Samba 3.2.5, everything works with no problems. But if clients have Samba 3.3.2, I get a warning "Your password has expired" everytime I try to change the password. The passwd command returns an "Authentication token expired: password unchanged" message, but the password is changed anyway. This makes me think that the problem is on the cient, since the server is changing passwords OK.

I have searched the logs, even with loglevel=5, on both server and client, but found nothing. Can anybody give me some clue on where to search?
Thanks.
