Hi Yannick,
great advise - /etc/shadow group was set to root,
after changing it to shadow desktop unlocking works again!

Thanks a lot !

Do you have any background information,
eg. which package(s) are responsible for /etc/shadow?
Should they check for proper file permissions during update?

The affected system images were very old
I had them initially set up at woody times
and ever upgraded since on the sid tree..
