About this tag
The idmap ad tag on WindowsForum.com covers discussions about the interaction between Active Directory domain controllers and Samba-based file and print services, particularly in the context of Microsoft's 2025 Netlogon hardening updates. These updates, part of cumulative security patches, modify how AD DCs handle Netlogon RPC calls to address vulnerabilities like CVE-2025-49716. Users report compatibility issues with Samba's idmap ad backend, which maps Windows SIDs to Unix UIDs/GIDs. The tag focuses on troubleshooting these integration challenges, including configuration adjustments needed to maintain functionality after security updates. Topics include Samba domain member setup, winbind idmap configuration, and resolving authentication or resource access problems in mixed environments.
