A flaw was found in SSSD. When configured to enforce account expiration using LDAP (Lightweight Directory Access Protocol) shadow attributes, SSSD fails to treat an expiration value of zero as an expired account. A user with valid credentials for an expired account can exploit this flaw to bypass access controls and authenticate to the system. This allows unauthorized access to persist after the account was intended to be deactivated.
