 Recording Samba for Integrators

Volker Lendecke, SerNet co-founder and long-time Samba Team member, was once again a speaker at SDC EMEA. At this year’s conference (February 4, 2020 – Tel Aviv, Israel) he specifically addressed integrators who want to use Samba. The recording is available on YouTube: https://youtu.be/RHHsTfKmI_c (direct link).

    • Common complications and performance issues
    • Samba features for NFS interoperability
  • Samba authentication:
    • Overview of authentication mechanisms in the Active Directory world
    • The role of Samba's winbind daemon: Authentication and idmapping
    • Winbind API and services for non-Samba SMB servers
  • Samba Remote Procedure Call services:
    • Requirements for seamless Windows interop beyond SMB
    • Protocol description for RPC services (direct TCP, named pipes)
    • Samba components that help non-Samba SMB servers

For the first time the Samba eXPerience 2020 will take place as a digital event. The 19th international conference around the OpenSource software Samba will be held from 26th - 28th May 2020 as an online event, sponsored by Google and Microsoft. The virtual participation is free of charge, registration is via https://sambaxp.org. Unfortunately, the planned IO-Lab has to be cancelled.

Due to the current COVID-19 situation and the resulting travel and assembly restrictions, the organizing committee has decided to realize a digital edition of sambaXP this year. The speakers will give their presentations live from their desks, so that participants can follow the conference from anywhere in the world via the Internet. Compared to the usual event format, the online event offers even more flexibility: simply switch between tracks running in parallel or follow two presentations simultaneously - no problem at all. The event is also recorded and will be available online at a later date.

The traditional tutorial by Stefan Kania will also be held as a webinar on the day before the conference (Tuesday, 25 May 2020). This year's topic: "Clustering with CTDB". There will be a fee of 50 Euro for participation. Booking is also possible via https://sambaxp.org.

The sambaXP is the annual meeting of the international Samba team with developers, users, manufacturers and system houses from the Samba ecosystem, which has been held annually since 2002. Questions arising from the change in the event format, among other things, will be answered by the organizing committee on the conference website at https://sambaxp.org.

The organizing committee is also available to answer any questions at loc@remove-this.sambaXP.org.
