A persistent challenge in enterprise infrastructure persists: finding a truly viable self-hosted alternative to Microsoft Active Directory that seamlessly handles Windows domain joining, Linux authentication, and modern protocols like SAML/OIDC. As organizations increasingly operate in hybrid OS environments, the limitations of existing solutions spark debate about sovereignty versus practicality.

Despite advances in multi-factor authentication and zero-trust frameworks, compromised credentials remain responsible for nearly half of all breaches. This deep dive explores why password vulnerabilities persist in hybrid environments and outlines actionable strategies for implementing intelligent password controls that adapt to human behavior and evolving threats.

Microsoft has confirmed that its September 2025 security updates are causing critical Active Directory synchronization failures on Windows Server 2025, particularly for large security groups with over 10,000 members. IT administrators are urged to apply a high-risk registry workaround immediately, with the company warning that incorrect modifications could necessitate a full OS reinstall.

Kerberos, the backbone of Windows authentication, remains a complex and critical attack surface in enterprise networks. Compass Security's upcoming six-part video series dissects its inner workings, attack vectors, and defenses — essential viewing for red and blue teams alike.

Kerberoasting exploits legitimate Active Directory protocols to crack service account passwords with minimal detection, posing a severe privilege escalation risk. Understanding its mechanics and implementing robust password policies, AES encryption, and SPN management is critical for defense. This deep dive reveals the attack's stages and actionable hardening strategies.
