The Ultimate Guide to Setting Up a Synology Directory Server in 2023 (2)

Did you know that Synology NAS provides Active Directory functionality? Properly install the Synology Directory Server package from Package Center and set up a Windows domain.

It's a great option for small businesses that want to control user access and simplify administration - combined with a file server role. Synology NAS offers two worlds. Typically, a Windows Server license with CALs (Client Access Licenses) costs around $1,000.

In this article, I will tell you how to set up Synology Directory Server.

Hardware requirements for Synology Active Directory Server

A Synology NAS with DSM version of at least DSM v6.2 or later is required. The current version at the time of writing this article is 7.1. I recommend using the latest version.

How to install Synology Active Directory Server

The Ultimate Guide to Setting Up a Synology Directory Server in 2023 (19)

You can find the Synology Directory Server package in the Package Center of your Synology NAS. If you see the packaging, your NAS is compatible.

You also need to install DNS Server package, which you can find in Synology Package Center. I recommend installing a DNS server first, as this is a requirement. No DNS Manager configuration is required as Synology Directory Server package handles everything.

You need to configure one thing on your DNS server. It is redirected to a DNS server connected to the Internet. It can be the IP address of your internet router or an external DNS server, eg Google, 8.8..4.4. In the image below, I have configured a forward to an incoming internet router.

A reader kindly mentioned that adding an external DNS server in the domain/LDAP settings in the control panel would also work. Add additional DNS servers, separated by commas.

Configure Active Directory Server

After installing the Active Directory Server package, you can find it in the main menu. Click on the package and a wizard will guide you through the package. The first question is critical. You will need to enter the domain name and password of the administrator account. Before setting up your server, take some time to choose your domain name.

Go to DNS Manager. You will see a new DNS zone (Active Directory integrated) containing your domain name. As you know, Windows Active Directory requires a DNS zone. The installation wizard will create it automatically. If you click on a region name, all standard datasets will be displayed. When each client joins the domain, a new record is created for it. Of course, you can also create records manually.

Manage Synology Active Directory Server

In the three tabs on the left, Status, Users and Computers, and Policy Domain, you're back in Active Directory. The Users and Computers tab shows the structure of Active Directory. It's the same structure you see in a Windows domain. The Add button allows you to create new users, computers or organizational units.

However, I recommend co-managing Active Directory on Windows 10 machinesRSAT(remote server administration) tool.

Starting with Windows 10 October 2018 Update, RSAT is included. You need to enable it using the "Features on Demand" option. After successful activation, you can find the RSAT tool under Windows Administrative Tools.

Don't forget to join your Windows 10 computer to the domain first.

Shared folder

I will use my Synology NAS to create shared folders. To do this, go to "Shared Folders" in the Control Panel. New in the Permissions tab: you can select Domain Users and Domain Groups from the drop-down menu. As you know, local users and local groups still exist. These are local accounts of the Synology NAS. If you have created any accounts, they will remain unchanged after installing Synology Directory Server.

Group Policy

There is no option to use Group Policy on Synology NAS. However, you can use RSAT's Windows Group Policy Management Tool. It works the same, I haven't found any issues with Synology Active Directory Server yet. It's a great tool for small businesses to set up folder redirection, roaming policies, or drive mapping. Even for businesses with 20 or fewer computers, it makes sense to organize your network and provide your users with a consistent experience.

some suggestions

I have found that using the "User must change password at next logon" check mark does not work when using the Windows Active Directory for Users and Computers (ADUC) tool. You get a strange error message. Please set this option on your Synology NAS if you want to use it.

In theory, you could also use other packages from your package manager. But I suggest you don't use them or use them as little as possible. Only use Synology NAS as "Windows Server". Better to buy another NAS.


It's helpful to think about how to secure your server. The general backup rule is to save your data3 times.1x production and 2x backup.

In Package Center you'll find a great package called "Hyperbackup". You can choose to back up to an external USB drive, or add another Synology NAS as a backup destination and use it to store data offsite.

Hyperbackup provides the ability to back up data to a cloud provider. I recommend backing up to another Synology NAS and additionally backing up to the cloud. For example, Amazon S3 is a low-cost cloud provider. Of course you can also choose other suppliers. Hyperbackup supports all of these and is easy to set up.

When choosing a cloud provider, figure out which one is best and whether you can easily store your data abroad.

Back to the backup rule: Storing data in the cloud would be third backup.

Q&A section.

Can Synology Active Directory replace my Windows domain?

Synology Active Directory (AD) provides a domain controller (DC) to replace the Windows domain controller. So the answer is yes. However, if you already have a licensed Windows Server, I would not change your domain to a Synology NAS unless the license is for an older version of Windows Server.

What is the difference between Active Directory and a domain controller?

no difference. These two words mean the same thing.

How to connect my Windows PC to Active Directory hosted on Synology NAS?

This is the same procedure you would follow if you had a Windows domain controller. You need to know the domain name and domain account ID with domain administrator rights.

latest comment

Synology NAS provides a Windows server as a domain controller, eliminating the need to purchase expensive Windows licenses. Installing and maintaining a Windows server is a complex process. Using a Synology NAS as a directory service is very easy. It also helps minimize IT support costs. However, it is best not to forget to update your Synology NAS to take advantage of the latest security updates.

Overall, Synology NAS is easy to set up. If you're looking for a simple, software-based solution, this is it.
