The SSSD logs aren't showing anything wrong because they have nothing 
to do with the execution of the SUDO rules in this situation. All the 
SSSD is doing is verifying the authentication (when sudo prompts you 
for your password).

The problem with the rule is most likely happening inside SUDO itself. 
When you specify 'sudoers: files, ldap' in nsswitch.conf, it's telling 
SUDO to use its own internal LDAP driver to look up the rules. So you 
need to check sudo logs to see what's happening (probably you will need 
to enable debug logging in /etc/sudo.conf).

Recent versions of SUDO (1.8.6 and later) have support for setting 
'sudoers: files, sss' in nsswitch.conf which DOES use SSSD (1.9.0 and 
later) for lookups (and caching) of sudo rules.
