The Ultimate Guide to Connecting Ubuntu Server to Windows Domain
Greetings, tech enthusiasts! In today’s digital age, businesses are looking for ways to increase productivity and streamline their processes. One way to achieve this is by connecting Ubuntu Server to a Windows domain. Joining Ubuntu Server to Windows Domain enables users to access shared resources without the need for separate accounts. In this article, we are going to explore how to join Ubuntu Server to Windows Domain in a step-by-step guide.
Introduction
Before we dive into the technicalities of joining Ubuntu Server to Windows Domain, it’s essential to understand what Ubuntu Server and Windows Domain are.
What is Ubuntu Server?
Ubuntu Server is a free and open-source operating system built on the Linux kernel. It is designed to be used for network servers, cloud computing, and data centers. Ubuntu Server is widely used for its stability, security, and ease of use.
What is Windows Domain?
Windows Domain is a network of computers that share a common database called Active Directory. Users can log in to any computer on the network with a single set of credentials. Windows Domain provides centralized administration and allows IT personnel to manage users, groups, computers, and other resources.
Why Join Ubuntu Server to Windows Domain?
Joining Ubuntu Server to Windows Domain has several benefits. It allows users to access shared resources with a single set of credentials, eliminates the need for separate accounts, and simplifies the administration of the network. It also enhances security by providing centralized control over access to resources.
Prerequisites
Before we start the process of joining Ubuntu Server to Windows Domain, we need to make sure we have the following prerequisites:
Prerequisites |
Description |
|---|---|
Ubuntu Server |
A running instance of Ubuntu Server on a physical or virtual machine. |
Windows Domain Controller |
A Windows Server with Active Directory Domain Services installed. |
Static IP Address |
A static IP address assigned to the Ubuntu Server. |
Joining Ubuntu Server to Windows Domain
Now that we have our prerequisites in place let’s start with the process of joining Ubuntu Server to Windows Domain.
Step 1: Install Required Packages
Before we can join Ubuntu Server to Windows Domain, we need to install the required packages. Open the terminal and run the following command:
sudo apt-get install realmd sssd samba samba-common-bin
This will install the necessary packages for joining Ubuntu Server to Windows Domain.
Step 2: Join Ubuntu Server to Windows Domain
Once the packages are installed, we can proceed with joining Ubuntu Server to Windows Domain. Open the terminal and type the following command:
sudo realm join --user=admin@example.com example.com
Note: Replace admin@example.com with your domain administrator’s username and example.com with your domain name.
You will be prompted to enter your domain administrator’s password.
Step 3: Verify Connection
Once the join process is complete, we can verify the connection by running the following command in the terminal:
sudo realm list
This will display the domain name and the domain controller’s IP address.
Step 4: Configure SSSD
We need to configure SSSD to allow Ubuntu Server to authenticate users with the Windows Domain. Open the terminal and run the following command:
sudo nano /etc/sssd/sssd.conf
Add the following lines at the end of the file:
[sssd]domains = example.comconfig_file_version = 2services = nss, pam[domain/example.com]ad_domain = example.comkrb5_realm = EXAMPLE.COMrealmd_tags = manages-system joined-with-adclicache_credentials = trueid_provider = aduse_fully_qualified_names = truefallback_homedir = /home/%u@%daccess_provider = ad
Note: Replace example.com with your domain name.
Save the file and exit.
Step 5: Restart SSSD
After configuring SSSD, we need to restart the service by running the following command:
sudo service sssd restart
Step 6: Test Authentication
We can now test authentication by logging in to Ubuntu Server with a domain user account. Open the terminal and run the following command:
id domainuser
This will display the user’s group memberships, indicating that authentication was successful.
Step 7: Configure Access Control
We can now configure access control to restrict or allow access to users and groups. Open the terminal and run the following command:
sudo nano /etc/security/access.conf
Add the following lines at the end of the file:
+:domain\users:ALL-:ALL:ALL
Note: Replace domain with your domain name.
Save the file and exit.
