Comment 14 for bug 1249777

Sorry for the noise.

Working through this, it's probably a config issue. On joining a host via freeipa-client-install, nsswitch.conf is updated to add sss to sudoers, however sssd.conf is *not* created with "services = sudo", so every sudo call gets a hard error trying to look up the defaults entry. As soon as sudo is added to the sssd services list, the spurious emails go away, even if there's no cn=defaults in the IPA directory.
