Samba 4.23 Released with SMB3 Unix Extensions Enabled by Default
linuxiac, Friday, September 12th, 2025
Samba 4.23 enables SMB3 Unix Extensions by default, improving POSIX interoperability for Linux and UNIX clients with proper permissions and symlinks.
Six months after its previous 4.22 release, Samba, the renowned open-source software suite that facilitates file sharing and printing services across various operating systems, including Windows and Unix, has released its latest version, Samba 4.23.
The main highlight - SMB3 Unix Extensions are now enabled by default. That means Linux and UNIX clients gain proper POSIX semantics-things like correct permission handling, symlinks, hardlinks, and special file types-without extra configuration. Windows clients that don't support these extensions will continue to work normally.
