There was an issue in an older version of SSSD which saved a wrong UPN in the cache. Please check if the latest version of SSSD for your platform installed, stop SSSD, remove the cache file in /var/lib/sss/db/, start SSSD and try again. If you do not want to remove the cache completely you can use e.g. ldbedit to delete the offending entry individually, search for user@domain@DOMAIN.
