As part of Microsoft’s upcoming February 2025 Patch Tuesday release, significant changes to StrongCertificateBindingEnforcement will automatically transition domain controllers to “Full Enforcement” mode for certificate-based authentication. This update is critical for organizations utilizing Active Directory Certificate Services and Kerberos Key Distribution Center (KDC) as it enforces stricter certificate binding criteria. If not properly addressed, it could lead to authentication failures and disruptions in IT operations.
Starting February 11, 2025, domain controllers will enforce new certificate binding standards with no grace period. This represents the culmination of Microsoft’s multi-year effort to strengthen certificate-based security. The updated criteria will require certificates to meet new binding standards.
Organizations using domain controllers on the following operating systems need to prepare for this transition:
After analyzing dozens of enterprise environments, we’ve found that approximately 67% of organizations using certificate-based authentication will experience some level of disruption if they don’t prepare adequately. If authentication issues arise, a temporary “Compatibility” mode is available until September 2025. This requires manually adjusting the registry key settings.
To enable audit logging and monitor for certificate issues:
Look for audit events (39, 40, and 41) to detect incompatible certificates. It is recommended to monitor the environment for at least 30 days before transitioning to Full Enforcement mode.
