This bug "affects" me too. In a way that sssd fails to start. Also any attempt to run something like "systemctl enable foo.service" is now being rejected after entering correct password in pkexec popup window, so I have to use "sudo systemctl enable foo.service". Log show sssd.service and its "sub-services" fail to activate. All these is happening after the update from Focal to Groovy.
