A vulnerability in SSSD occurs when configured with the LDAP access provider and ldap_access_order including ppolicy or lockout. If a user lookup returns zero results, a fail-open condition in the LDAP ppolicy access check can cause an incorrect success response and cache an allow decision. This permits continued authorization for deleted or deprovisioned users. A remote attacker with prior valid account context could exploit this to maintain access and potentially make limited modifications to resources no longer authorized.
