Description of problem:
When sudo is used with sssd and a local user runs sudo, an e-mail is sent to administrator, because sssd does not support sudo rules for local users. It is not an error, only noise.

Version-Release number of selected component (if applicable):
sudo-1.8.6p3-1

Steps to Reproduce:
1. configure sudo to use sssd as data source ('sudoers: files sss' in /etc/nsswitch.conf
2. run sssd
3. log in as local user
4. run 'sudo -l' as local user
  
Actual results:
E-mail is sent to administrator:
"problem with defaults entries ; TTY=pts/2 ; PWD=/home/fuero"

Expected results:
No e-mail is sent.
