I get logs of entries of the following in the logs:
2026-08-30T17:30:01.076698+02:00 twentytwo CRON[205460]: PAM unable to dlopen(pam_kwallet5.so): /usr/lib/security/pam_kwallet5.so: Kann die Shared-Object-Datei nicht öffnen: Datei oder Verzeichnis nicht gefunden
2026-08-30T17:30:01.077676+02:00 twentytwo CRON[205460]: PAM adding faulty module: pam_kwallet5.so

In English:
Cannot load the shared object file: File or directory not found.

And yes, this file does not exist.

So either this is a missing dependency (hopefully not) or it should be
added to an appropriate logcheck rules (if it is harmless), so it
won't fill in the filtered logs.
