localkdc testing

The localkdc testing tag covers Microsoft's introduction of LocalKDC and IAKerb in Windows 11 and Windows Server Insider builds. These features enable Kerberos authentication in scenarios that previously fell back to NTLM, such as when domain controllers are unreachable or for local account connections. This development is part of Microsoft's effort to reduce reliance on NTLM, addressing a long-standing security concern. Discussions focus on the operational implications of moving toward a Kerberos-only authentication model and the testing of these new capabilities in Insider previews.
