ntlm phase-out

The ntlm phase-out tag covers Microsoft's ongoing efforts to deprecate NTLM authentication in favor of more secure protocols like Kerberos. Discussions include upcoming changes such as disabling legacy Kerberos PAC validation by April 2025, which affects Windows 10, Windows 11, and Windows Server. IT administrators must prepare for these updates to avoid authentication failures. The tag also addresses security vulnerabilities associated with NTLM and the broader shift toward modern authentication methods in enterprise environments.
