How To Join Linux Server To Domain

Joining a Linux server to a domain can be an intimidating task if you haven’t done it before. However, once you understand the steps, it becomes a straightforward process. In this blog post, we’ll guide you through the process and provide the necessary commands to get your Linux server connected to your domain.


To join a Linux server to a domain, you will need the following:

  1. A Linux server. This guide will use Ubuntu as our example, but the steps are similar for other distributions.
  2. Admin access to your domain.
  3. Access to the terminal on your Linux server.

Step 1: Install Required Software

Before you can join your Linux server to your domain, you need to install the SSSD and realmd packages. These packages provide the tools and services needed to manage domain memberships. To install these packages, type the following command into your terminal:

 sudo apt-get install -y sssd realmd 

Step 2: Join the Domain

Now that you have installed the necessary packages, you can join your Linux server to your domain. To do this, you will need to input the following command:

 sudo realm join --user=domain_admin 

In the above command, domain_admin should be replaced with the username of an account that has administrative rights on the domain, and should be replaced with the domain you want to join.

Step 3: Verify the Join

After joining the domain, it’s important to verify that the operation was successful. You can do this by running the following command:

 realm list 

This command will list all domains that the server is a member of. If the join was successful, you should see your domain listed.


That’s it! You’ve successfully joined your Linux server to your domain. While the process may seem a bit complex at first, with a bit of practice, it becomes a simple task. If you encounter any issues during the process, don’t hesitate to consult the man pages for the sssd and realmd packages for more information.
