Watch sambaXP 2022 recordings

Although online once again, sambaXP 2022 was a great event for sharing new developments and exploring ideas around Samba, with participants and speakers from all over the world.  Special thanks to this year's sponsors GoogleMicrosoft and SerNet..

Presentations are all available online in the sambaXP 2022 YouTube playlist.

These talks can be re-watched:

Organizer SerNet hopes to host sambaXP again next year on-site in Goettingen, Germany. The entire team is looking forward to a physical community reunion. 

SAMBA+ 4.16.2 has just been released by SerNet. Packages for various SUSE and Red Hat platforms as well as for Debian GNU/Linux, Ubuntu and AIX are available now.

There are now also packages available for RHEL 9 and the upcoming Rocky Linux 9, AlmaLinux 9, Oracle Linux 9 releases.

These package updates address several issues, which are listed in the release notes:


The SDC EMEA 2022 will be hosted as Virtual Conference on June 14, 2022. SerNet is happy to be a Branding Partner and to support the event. Several talks from SerNet colleagues are scheduled as well. Registration to participate in the conference is still open. 

A SMB3 Interoperability Lab will be part of SDC EMEA. Starting on June 14, the IO Lab will go on till June 16. The IO Lab is the (virtual) place to test implementations of SMB3 in a collaborative setting with the goal of providing a forum in which companies can develop interoperable products. New features that have recently been added to the SMB3 protocol will be presented.

The Samba team at SerNet GmbH will reprise talks from the recent sambaXP 2022:

  • Ralph Böhme: smbd, what's next? (12:20 p.m. CEST)
  • Volker Lendecke: Symlink races for dummies and how to deal with them (12:40 p.m. CEST)
  • Stefan Metzmacher: Kerberos/Authentication Updates in Samba (4:10 p.m. CEST)

So, if you missed sambaXP this year, SDC EMEA is a chance to catch up.

SAMBA+ 4.16.1 has just been released by SerNet. Packages for various SUSE and Red Hat platforms as well as for Debian GNU/Linux, Ubuntu and AIX are available now. This is the first stable SAMBA+ release of the new Samba 4.16 release series. Please make sure to test thoroughly before upgrading and read the release notes carefully! Details on upgrading can be found in the SAMBA+ HowTo collection.

The release notes, which contain information about changes and new features of the new major release, are available here:

A particular point to emphasize is the following:

  • New samba-dcerpcd binary to provide DCERPC in the member server setup
    This novel development found its way into upstream Samba thanks to Volker Lendecke, long-time Samba team member and co-founder of SerNet. He has been working on this for a long time and with the creation of a new samba-dcerpcd binary he made it possible that DCERPC services can be used independently of smbd. This opens up new standalone usage scenarios for DCERPC outside the samba framework, e.g. samba-dcerpcd can be used with the Linux kernel SMB2 server ksmbd or other SMB2 server implementations.

Another important point:

  • SSSD compatibility
    SAMBA+ 4.16 packages for Red Hat and SUSE based platforms can now be used in combination with the System Security Services Daemon (SSSD), even with SSSD as member of an Active Directory domain. Please note that SerNet still strongly recommends to not use SSSD on file server setups, since this has some limitations and complicates the server configuration.

    In this context additional RPM packages have been added and package dependencies changed. On usual setups the sernet-samba-common-private package will sernet-samba-common. In combination with SSSD sernet-samba-common-private requires Red Hat's or SUSE's samba-common package.

    The sernet-samba-python package has been renamed to sernet-samba-python3, which depends on sernet-samba-python3-private. Usual setups just require the new sernet-samba-python3-private package. If you are running your own or third party scripts, which make use of sernet-samba's Python modules, you can install the sernet-samba-python package to make the modules available in the standard (site-packages) library path.

The new packages also address the issues, which are listed in the Samba 4.16.1 release notes:

and the following additional issues:

  • Bug 15050: smbclient no longer can connect to Azure
  • Bug 14054: Kerberos Pre-Authentication updates badPwdCount for the 2 newest passwords in the history and results in ACCOUNT_LOCKED_OUT
  • Bug 14125: As kerberos service/acceptor we may not accept tickets with our previous machine password 
  • Bug 12907: pam_winbind with krb5_auth or wbinfo -K doesn't work for users of trusted domains with more than 1 hop between server and user realm

Gnome tracker support has been removed from Samba's MacOS Spotlight service. SerNet recommends to use the more scalable Elasticsearch backend. The content of the sernet-samba-spotlight package has been merged into the sernet-samba package.

With the new 4.16 release Samba 4.15 has been turned into the "maintenance mode" and Samba 4.14 into the "security fixes only mode". Samba 4.13 will not receive any updates beyond this point. The SAMBA+ 4.13 repositories will be disabled soon. Please update to a more recent version of SAMBA+. If you need assitance updating, have a look at our support services

As another choice mainly of interest for OEM, SerNet offers an on demand Long Term Support (LTS) option, prolonging the time span for security updates.

The Samba Team at SerNet has just released the SAMBA+ 4.15.7 packages. They are available for various SUSE and Red Hat platforms as well as for Debian GNU/Linux, Ubuntu and AIX.

The update addresses several issues, which are listed in the release notes for Samba 4.15.7.
