Given the private key of an AD CS root or subordinate CA trusted for domain authentication, an operator can forge an authentication certificate for an enabled account and use it for PKINIT to request a Kerberos TGT. The forged certificate bypasses the normal CA issuance workflow and may provide persistence beyond password changes while it and its issuing CA remain accepted. Success depends on account state, certificate mapping, revocation, and KDC trust configuration.
