[Samba] user login passwords are mixed up

[oeh univie edv lists]

Hello,

Some users in my domain report that they have to use different (old)
passwords on different computers. They say that they still have to use
their "old" passwords after they changed it. My domain setup is that users
are asked to automatically change their password on Windows 7 Enterprise
after some months. So they have to do that. Otherwise they cannot login.
But why is it, that the old password is still requested on some computers?
Can this happen, when users do not turn off Windows 7 computers (are still
logged in on the PC where they changed the passwort) and switch to other
computers? 

I looked in all relevant logs in /var/log, auth.log and in all logs in
directory samba. I cannot even find ANY information for user
authentication. Where to look? Which log is relevant? How to rise the log
level?

I run a Samba Active Directory DC 4.1.17 on Debian Jessie. 

I attached some logs to the mail how /var/log looks ... hardly any looging
except for startups and shutdowns of samba. I restartet samba and attached
the logs. How to monitor this problem? 

Any help why this happens is much appreciated.

KR, birgit
