It’s been a while since the last article published in this blog. There have been a lot of things going on in my offline life. So, in this article I will guide you how to integrate TrueNAS with the existing Windows Active Directory (Domain Controller). TrueNAS supports Windows Active Directory and LDAP integration. The steps are very simple and easy. With this integration, we can give the existing Windows Active Directory Users and Group access to the TrueNAS.
Steps to Join TrueNAS with Windows Active Directory Services
Before we continue, I assume you already have a working Windows Active Directory Services in your network. In this example, I use Windows Server 2025 as my Domain Controller. Next I will guide you how to build our own Domain Controller using Windows Server 2025.
Step 1. Install and Set Up Windows Domain Controller
Skip this step if you already have. The information that we need are:
- Domain name: EQUATOR.LOCAL
- Admin user: Administrator
- Password: YourDomainAdminPassword
Step 2. Configure the DNS
We need to set up the DNS in the TrueNAS to the Domain Controller first. Only then we can enable the Directory Services. Go to Network and then click Settings on the Global Configuration. Change the DNS to the IP address of te Domain Controller.
Click Save.
Step 3. Configure Directory Services
Go to Credentials | Directory Services, Enter the Domain Controller details here such as Domain Name, Administrator account and the password. Click Save. If everything correct, you will see all the Domain Users and Groups in the TrueNAS.
Enjoy,
