How to Join a Linux Machine to Active Directory (Ubuntu 20.04)
Вставка
- Опубліковано 17 січ 2021
- 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.

THANKS! You are the ONLY tutorial I found in like 2 hours or so, that actually worked
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!
The quality of your videos is great! Thank you for doing this!
No problem! Thank you for the support
Cool stuff - I've never joined a Linux box to AD before, so this is helpful.
Awesome! It's a great addition to any home lab 😉
Awesome video, thank you so much! Thought this would have taken much longer!
Thanks so much for this super guide! It worked perfectly! I look forward to more such stuff. Good job and keep it up.
After replicating your "admin" for root access, I am getting error that the user is not authorised to do sudo su and yet the user in in that admin group in domain controller. Not sure when I need fix. Otherwise thanks.
Worked perfectly. Thanks Conda..
This was really helpful and precise. Thanks!

Thank you for the support 😁
Interesting! thanks bud ;)
No problem man! Thanks for watching!
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!
permission denied when trying to login.
very helpful
next time I will search UA-cam first before Google...Good job brother...
thank you for the video i have to move our ubuntu desktops from 1 active directory domain to another do you any helpful tips?
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.
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.
this is really great, but can you please make the font bigger
Definitely will do in the future. Thanks for the feedback!
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
Hi, does the IP of your linux VM matter? What about the network adapters? Thanks :)
Hi , can you please tell me how to perform the sudo vim/etc/resolv.conf i am unable to resolve the host and getting temporary failure in name resolution and sudo:vim: command cannot found
Vim is a texteditor. You can use also sudo nano.
Are you running ESXi on a physical server or on a vm??
I run it on a physical server
Which one is the windows set up video? It's not linked as said on the video.
Can we add windows machine to linux domain server? if yes , any reference on how to do that
Can an Active directory be used along with other Linux servers? If yes, how? If no, Why?
You want a challenge? Try to do the same, and implement Smart Card authentication...
2:24 Im having an issue with Resolv.config - the whole file is empty and I do not what was shown in the vid. Any ideas why?
me too. i hope we find someone who can help us.
@@dada0900 If It's empty just type nameserver then go to the next line and type search
in your terminal screen enlarge the font so a person can actually read whats going on.
After finishing everything really worked and I can access with the users. But access to web pages and the internet is not enabled, what could it be?
can someone explain why I get realm: command not found. I installed the realm package by sudo apt-get install sssd realmd -y
I must be missing something, this works until I reboot, then the resolv.conf gets truncated and breaks DNS. Only way I've been able to fix is to enable/start systemd-resolved.service, edit the resolv.conf again, then stop/disable. Which will work until I reboot again.
Did you know why i cann't change the password in first login or after for a user?
kindly tell how copy local account profile(data, settings etc) to azure account after joining azure in ubuntu
Please help me on How to apply windows server group policy to Linux client
Hi , I have this kind of issue can you help me. what is issue here ?? realm: Cannot join this realm
If ubuntu linux client finds windows server and dns, but domain not found. What could be the reason? You can try telnet connet to 53 port and it works. I try to understand more.
Maybe it is that you have to edit resolv.conf? It won't work with out it?
The sudo systemctl set-hostname should be as $ sudo systemctl set-hostname conda.local not ubu-1.conda.local. This helps to alleviate confusion
Will this ubuntu machine appear in computers OU in Active Directory? If not, is it posible to do so?
It will
Hello, I need help, installed ubunto 20.04, but add domian, i have this See: journalctl REALMD_OPERATION=r16127.10824

I think the screen resolution could be set properly. It looks so small :-(

You have nowhere mentioned about starting sssd service. When you start sssd.service then it will check for /etc/krb5.keytab which is not automatically created. So I am sorry to say that the information provided in this video is not satisfactory.

Congratulations! You'll go down in this video's history 🤣
