For this tutorial I will be walking through how to use a tool called Realmd to connect an Ubuntu Server or Ubuntu Desktop system to a Windows Active Directory Domain.

In the past I wrote an article talking about how to use Powerbroker Identity Services to do the same thing, but the scope of the article was limited to the server version of Ubuntu only. Furthermore, it has since been my experience that PBIS is an unreliable solution at best.

Part of the confusion I have had on this issue in the last two years has been in thinking that there are only one or maybe two ways to make an Ubuntu Desktop/Server OS connect to a Microsoft Active Directory domain and they both used the same underlying stuff. In fact there are more like 10 different ways to do it all using a mix and match of different technologies.

Finally, I don’t like proprietary stuff. PBIS, while having a free version, was still proprietary. Today we will be using a suite of tools called SSSD. SSSD was created by Redhat and it’s opensource. Furthermore we will be using RealmD, which is a “wrapper” of sorts for SSSD that makes it easier to setup and configure. That’s the short of it. Let’s get started. (more…)
