Information leak when SSSD is used for authentication against remote server:
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.(CVE-2017-7488)
