Were you previously using sssd? Or is the problem merely that it is now reporting an error starting a service that you don't use? Are there any files in /etc/sssd/conf.d, or does /etc/sssd/sssd.conf exist? If so, what are the contents of those files? What are the contents of /usr/lib/systemd/system/sssd.service? If you run "journalctl -u sssd.service", are there any log entries older than the package update?
