Hello, Today morning I had a bad surprise. Suddenly I cannot login anymore to my PC. My OS is Arch based, with SSSD 2.4.2, updated yesterday (it was working after update, last login occurred around 7pm 05.05.2021, today 7am 06.05.2021 cannot login anymore) Maybe you have any idea what's wrong. What I see in sssd logs:
