SUMMARY
***
After an upgrade from Kubuntu 20.04 to 22.04 no mounts are working anymore. All
dependencies are installed and former (20.04) it worked fine. Using cifs-utils
via mount command works, too. I already tried the polkit hint mentioned in the
manual, but sadly it wasn't a solution. Kernel.log shows the following:

It's just our common file server at the university. Login via Active Directory,
nothing special. As mentioned before, mount -t cifs commands work as expected.
How to debug this?
***
STEPS TO REPRODUCE
1. Upgrade from Kubuntu 20.04 to 22.04
2. Just try to mount something
OBSERVED RESULT
Smb4k is again showing dialog for username and password and is not mounting the
desired network filesystem.
EXPECTED RESULT
Mount should be successful.
