today I was able to play around some more. I installed a new VM with Ubuntu 20.04. The domain join is done by our install script. I changed it to set log level to 6.
I logged in with a user, disconnected the LAN connection and logged out.
Then I was not able to login for a few minutes. Without doing anything but wait a login was possible. I guess it took a while to discover that the offline credentials needed to be used.
