Domain

Your DiskStation can join a domain service. After joining the domain, domain users can sign in to your DiskStation using their domain accounts and passwords, allowing them to access files and use DSM applications without the need to remember another set of usernames and passwords.

To join a domain:

  1. Go to Control Panel > Domain/LDAP > Domain.
  2. Tick the box Join domain.
  3. Enter the domain name and specify the DNS server in the appropriate fields.
  4. If necessary, tick the box Advanced domain options. (See below for details.)
  5. Click Apply.
  6. In the popup window, enter the username and password of the administrator of the domain.
  7. Click OK.

DNS Server

We recommend specifying a DNS server to help your DiskStation search for the domain. If the domain, however, is not registered on the DNS server, the procedure of joining the domain may fail.

Domain Server Type

This field shows the domain type when your DiskStation joins a domain. The domain type will be "AD domain".

Management Mode

This option will determine how you manage the privileges of domain users and groups.

Advanced Domain Options

In most cases, you do not need to fill in any of the advanced domain options. Advanced domain options are needed only for specific domain environments.

Joining Read-Only Domain Controller

To join your DiskStation to a read-only domain controller (RODC), you need to specify the "full computer name" (FQDN) of your read-write domain controller (RWDC) in the DC IP/FQDN field. The full computer name should be in the following format: ComputerName.Domain, e.g., "ad01.synology.com".
