its now some time after your last reply, I had some trouble with my
network, set up all clients with fresh stretch and fixed some other

>>>172.16.0.209 sambawb.work.company sambawb
I added this line.

Yes, it's locked.

I removed pam-script and since then login with domain users seems to
work more reliable.
A deeper look showed me that earlier I told pam-script to 'service
winbind restart' on every logon because of earlier problems. Obviously
this (often) restart caused winbind to crash.
On the other hand it explains, why 'just loggin in as a local user'
'fixed' winbind login.

I wrote a cronjob for this and it's running after every failed login. I
will report when it finds something interesting, till now it doesn't.

I'm using Windows 2008R2 DC, not Samba.

So what's the cause for this? Okay, when winbind has crashed, it can not
find the UID, but usually this should be winbinds job to find UIDs.
For now I belive that winbind crashed because of often restarting, but
cronjob is paying attention for anormalies now. Our company is on
vacation right now, we are closed and I can not test in real situations.
I will report back when I know more.
So thank you for your help, perhaps someone could update debian wiki
with your guide to help others, too.
Thanks a lot,
