It's true that in 6.8, the sudo part was changed quite a bit, but we
haven't heard about any bugs so far. Could you please follow:
    https://fedorahosted.org/sssd/wiki/HOWTO_Troubleshoot_SUDO
and also:
    https://fedorahosted.org/sssd/wiki/Troubleshooting
to inspect SSSD logs? For authentication failed you'll probably want to
take a look at the domain logs and maybe the krb5_child.log
