Windows Server 2022 must be configured for name-based strong mappings for certificates.

Weak mappings give rise to security vulnerabilities and demand hardening measures. Certificate names must be correctly mapped to the intended user account in Active Directory. A lack of strong name-based mappings allows certain weak certificate mappings, such as Issuer/Subject AltSecID and User Principal Names (UPN) mappings, to be treated as strong mappings.

This applies to domain controllers. This is not applicable for member servers.

Verify the effective setting in Local Group Policy Editor.

Run "gpedit.msc".

Navigate to Local Computer Policy >> Computer Configuration >> Administrative Template >> System >> KDC >> Allow name-based strong mappings for certificates.

If "Allow name-based strong mappings for certificates" is not "Enabled", this is a finding.

Configure the policy value for Computer Configuration >> Administrative Template >> System >> KDC >> Allow name-based strong mappings for certificates to "Enabled".
