From f86580bd253e2adbb62730e2edb99eb25bf32658 Mon Sep 17 00:00:00 2001 From: "claude[bot]" <41898282+claude[bot]@users.noreply.github.com> Date: Fri, 7 Nov 2025 19:08:14 +0000 Subject: [PATCH 1/5] Test-DbaKerberos - Add comprehensive Kerberos diagnostics command Implements Tier 1 and Tier 2 checks (25 total checks) covering: - SPN validation (registration, duplicates, format, ownership, AG listeners) - Time synchronization (client-server and server-DC comparisons) - DNS resolution (forward/reverse lookups, CNAME detection) - Service account configuration (type, lock status, delegation settings) - Network connectivity (Kerberos, LDAP, SQL Server ports) - Security policy (encryption types, secure channel, hosts file) - SQL Server configuration (service account, network protocols) - Authentication validation (current auth scheme via DMV) - Client-side checks (Kerberos ticket cache with klist) Tests include comprehensive mocking for CI compatibility since AppVeyor does not support Kerberos authentication testing.
