The Samba team at SerNet has completed another important milestone in the STF-funded development of the open-source Samba software: Milestone 3.3 focuses on improved integration with Linux desktop environments and is part of the broader SMB3 UNIX Extensions milestone group.

The goal of this work is to make Samba a more natural and consistent part of Unix-like operating systems. To achieve this, the team has extended libsmbclient, the client-side library used by major desktop environments such as GNOME and KDE to access SMB file shares. By enabling support for SMB3 POSIX extensions in this library, Samba now offers better handling of symbolic links, permissions, and metadata making file access on the desktop feel more like using a local Unix filesystem. The team also put in the work to provide the code needed for GNOME to enable the SMB3 Unix Extensions.

This milestone builds on earlier work within the SMB3 UNIX Extensions group: Milestone 3.1 focused on the server-side implementation of POSIX-compatible features. With Milestone 3.3, these improvements are now reaching Linux desktop environments and deliver the benefits of SMB3 UNIX Extensions directly to end users.

The achievement is part of the ongoing effort to enhance Samba’s security, scalability, and integration. The goal is to ensure that Samba remains a powerful, interoperable solution for sovereign IT environments and is funded by the Sovereign Tech Agency.

Patched SAMBA+ packages are now available to address the Netlogon protocol change introduced by Microsoft’s latest updates to Windows Active Directory Domain Controllers.

Following our initial announcement, the updates from Microsoft introduce a critical change that may impact Samba installations in certain configurations. To ensure compatibility, fixed SAMBA+ packages have been released for the following branches:

• SAMBA+ 4.21
• SAMBA+ 4.22

If you are still using an older release branch, we strongly recommend migrating to 4.21 or 4.22 to receive the necessary fix.

Who needs the update?
You only need to install the patched packages if:

• Samba is configured as a member server, and
• you're using the idmap backend ad

Other Samba setups are not affected.

For full technical details, please refer to the official Samba release notes:
Samba 4.21.7 Release Notes
Samba 4.22.3 Release Notes

Debian 13 "Trixie" has not yet been officially released, but SAMBA+ packages are already available. Starting with version 4.22, SerNet provides prebuilt SAMBA+ packages for the upcoming Debian release. Supported architectures are amd64 and arm64, in line with Debian’s decision to discontinue 32-bit variants.

By offering early access to these packages, the SAMBA+ team ensures that administrators and IT professionals can plan and test ahead. This proactive approach supports smooth transitions and secure operations in demanding environments.

Built from the official Samba source code, SAMBA+ packages offer more than just compatibility. They include extended testing, continuous security updates and the option for enterprise-grade support directly from SerNet.

All supported platforms, including the new Trixie packages, are listed in our overview. Technical setup instructions and repository details are available in the How-to Section.
