The Samba team has announced version 4.22.6, the latest stable release in the 4.22 series, bringing key fixes for macOS compatibility, Active Directory integration, Ceph stability, and clustered Samba environments.
Samba 4.22.6, released on October 16, 2025, focuses on improving system reliability and cross-platform performance. This update resolves multiple issues affecting macOS users, including DFS connectivity problems with Finder clients and Time Machine backup failures. Spotlight search behavior has also been refined to ensure more accurate and efficient indexing.
The update strengthens overall stability by fixing a crash in the rpcd_mdssvc service caused by uninitialized name mangling and improving lease handling logic to ensure the lease epoch only updates when a lease is granted.

Active Directory integration sees better resilience, addressing domain join failures when multiple domain controllers are returned. The ‘net ads group’ command now correctly lists domain groups, improving administrative operations in enterprise setups.
For distributed file system users, Samba’s Ceph module has been refined to enhance reliability during fsync operations. Meanwhile, clustered deployments benefit from expanded CTDB flexibility, allowing the CTDB_SOCKET feature to function even without CTDB_TEST_MODE.
Samba 4.22.6 is available for download as gzipped source and patch files. The release was contributed to by developers Ralph Boehme, Pavel Filipenský, Mike Liu, Anoop C S, Shachar Sharon, Andreas Schneider, and Martin Schwenke.
