sambaXP 2022 is online again

SambaXP is the annual meeting of the international Samba team and its ecosystem of developers, users and vendors all around the globe since 2002.

The 21st international conference around the OpenSource software Samba will take place from 31st of May - 2nd of June 2022. Due to the current COVID-19 situation the organizing committee is planning a  digital edition of the popular conference for 2022 again. The conference itself is free of charge - Please register here. The call for paper is already open.

The conference will again be held via Zoom - open mic and video as well as other channels will allow the community to interact in a better way.

Speakers will give their presentations live from their desks an participants can follow the conference from anywhere in the world via the Internet. The event will be recorded and published with the consent of speakers. Of course due to time restrictions it is possible that speakers record their presentation before and we play it during the event. However, we would like to ask you to use this option only in exceptional cases as not to lose the character of the live event.

Lectures are scheduled for the period from 3pm to 9pm german time zone (CEST) – We try to consider best time slots for all speakers regarding their time zone.

The traditional tutorial by Stefan Kania will also be held as a webinar on the day before the conference (Tuesday, 31st May 2022). This year's topics: "Setting up GPOs wit Samba & Disaster recovery of an Active Directory".

We are further pleased to announce that an Microsoft's SMB Interoperability Lab (IO Lab) will take place as a part of sambaXP. The purpose of this IO Lab is for vendors to bring their implementations of SMB3 to test, identify, and fix bugs in a collaborative setting with the goal of providing a forum in which companies can develop interoperable products. Please have a look at the agenda and stay updated here.

Do not hesitate to contact the organizers at loc@sambaXP.org.

Best regards - your sambaXP team at SerNet

Conference program 2022

Setting up GPOs wit Samba & Disaster recovery of an Active Directory

This year's sambaXP tutorial covers two interesting topics at once:

Setting up GPOs with Samba

Using GPOs is a fundamental technique in the Windows-world to mange the access to resources or to configure systems. One of the main topics in using GPOs are roaming profiles and folder redirection. Roaming profiles makes only sense if you also use folder redirection. If you don’t use it, profiles getting to big. The problem is: every time a user log in to a Windows-client the profile will be loaded via the network and if the user log off, all profile data will be send via network to the profile share. So redirection is very important. Samba can also configure the GPOs for roaming profiles and folder redirection.

In the first part we will create the GPOs and configure a Samba file server to store users home directory and roaming profiles. We will also configure folder redirection and take a look on how Samba mange to store both: user data and redirected data from the roaming profile.

In the second part we will see how Samba is managing the Linux-GPOs. Starting with Samba 4.14 it is possible to set up GPOs for Linux-hosts. In this part of the topic we will configure the domain controller to handle the Linux-GPOs and we will take a look which GPOs you can set up. We than configure a Linux-client to use the GPOs.

Disaster recovery of an Active Directory

Running an Active Directory with more than one domain controller will prevent you from a single point of failure. You should always have at least two domain controllers to store your objects and manage the user authentication. But what will happened if the hole Active Directory crashes? Then you need not only a backup of your Active Directors database, you also need a strategy how to recover your domain. We will take a look at what do you need to backup to bring your domain up again. We will backup from a running domain with “samba-tool” and recover the domain from the backup, up to the point that one domain controller will be back online.


What do you need to join the tutorial?

  • PC (BYOD) with “VirtualBox” and “Vagrant” installed
  • A Windows VM to test the setup and running RSAT
  • Webcam and speaker with microphone for interaction

If you don't have a Windows-VM you can download an evaluation Version from Microsoft https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/ Download the VirtualBox version and import the VM to VirtualBox. It's a full featured version valid for 40 days.


Training material:

You will get a handout including all steps to be able to recap independently after the tutorial.

Note: All the Linux-systems will be prepared - You will get a “Vagrantfile” to set up all the Linux-VMs needed for the tutorial.

SMB Interoperability Lab

The SMB3 IO Lab is free of charge and will run online during sambaXP with access to the online lab environment available 24 hours each day.

The purpose of this IO Lab is for vendors to bring their implementations of SMB3 to test, identify, and fix bugs in a collaborative setting with the goal of providing a forum in which companies can develop interoperable products. The 2022 SMB3 IO Lab will be held online on Microsoft Teams using a virtual private network. Participants of the IO Lab work together to define the testing process, assuring that objectives are accomplished.


Is it worth it to attend the SMB3 IO Lab this year?

In a word, Yes! SMB is changing and here’s your opportunity to be the first to learn more about the new functionality, to get your questions answered by the experts, and to test it out.

For example, here’s a quick look at some of the new features that have recently been added to the SMB3 protocol:

  • SMB3 now is able to communicate over QUIC, a new internet standard transport which is being broadly adopted for web and other application access
  • Support for AES-GMAC authentication
  • Support for share compression
  • Support for encryption over RDMA


The IO Lab offers access to:

  • The latest Windows client and server software from Microsoft, including test suites that help verify interoperability on various features of SMB protocols
  • Technical support from SMB engineers to look at traces and help with diagnosing problems


IO Lab participants are covered by a non-disclosure agreement and access is restricted to registrants only (more information regarding NDA will follow!)


If you are reluctant to participate because you feel that your SMB implementation is "not ready", you should still participate! The SMB Interoperability Lab is also a development opportunity, not just a testing opportunity. Implementations still in development are encouraged to participate.  It's a great opportunity to get help and learn from the experts!

This IO Lab is sponsored and featured by Microsoft.
