How to Join a Linux Machine to Active Directory (Ubuntu 20.04)

In this video, we talk about how to add an Ubuntu server to our existing Active Directory domain. This will allow the Linux machine to authenticate to the specified Kerberos realm from Active Directory. This allows us to SSH into our Ubuntu 20.04 server using credentials from the AD domain. We also discuss how to enable the creation of home directories on login, and sudo access defined by Active Directory groups.

OMG instructions online that actually works! Thank you so much for this! My team is using AWS with AWS managed AD, along with workspaces and EC2 servers. The few commands here did the trick

[rouvenlorenz]

THANKS! You are the ONLY tutorial I found in like 2 hours or so, that actually worked

[InfiniteLogins]

Cool stuff - I've never joined a Linux box to AD before, so this is helpful.

Thank You Thank You Thank You!!! This was the only tutorial I could find that actually worked!!! I've been trying for two days to authenticate domain users on the Ubuntu server and you are the only one who taught me correctly how to do it. Subscribed!

I recently switched my dev laptop from Windows 11 to pop_os 22 but had trouble getting it joined to AD. I ran the usual realmd install but whenever I tried to sign into the OS from the GUI, I got a grey screen. When I tried it from a console I got a message stating it couldn't figure out what my home folder was, so it defaulted to /. Not good. After a day of fiddling with kererbros defaults, I found this video and it fixed the problem immediately! Thank you!

I'm stuck at realm discover. It says there is no such realm. My DNS server sits inside a home server, so the gateway and the DNS server are not the same...maybe that's why, i just don't know how to do it in my case

[xenom]

How are you able to edit the nameserver address? When I try to change it, none of my changes register, it's like the page cannot be edited.

[MoonGlow]

I used realm discover but it couldnt found my domain, I used machine IP for DNS setting and probably thats where my mistake is.
How can I learn my domains DNS thing?

I followed the same step but there is some thing not right with this config as I see its allowing every login even you enter a wrong password. I am looking to see how to fix it.
