Language:
Active Directory relies on Kerberos for authentication. It is an older protocol that has since received various security hardening measures. For this reason, it's necessary to disable some legacy options (e.g. the obsolete "DES" encryption or "Do not require Kerberos preauthentication") to ensure proper security such as avoiding "AS-REP Roasting" attacks.
To ensure the highest level of security, configure the Active Directory's authentication protocol to use the latest security parameters and protocols.
