A flaw was found where authconfig could configure sssd in a way that treats existing and non-existing logins differently, leaking information on existence of a user. An attacker with physical or network access to the machine could enumerate users via a timing attack.

Mitigation

Possible workaround (with side-effects):
authconfig --enablesysnetauth --update
