How can I configure Microsoft Entra Domain Services single sign-on for a QNAP NAS?

Last modified date: 2025-08-22

Applicable Products

  • All NAS series
  • QTS 5.2.7 and later versions
  • QuTS hero h5.2.7 and later versions

Details

QNAP NAS supports single sign-on (SSO) with Microsoft Entra Domain Services, allowing users log in using their Microsoft Entra ID credentials. You can then manage the following for imported domain users:

  • Shared folder privileges
  • Domain group privileges
  • Domain user storage settings
Note
Microsoft Entra Domain Services (formerly Azure AD Domain Services) is a managed cloud service that provides domain join, LDAP, Kerberos, NTLM authentication, and Group Policy without the need to deploy domain controllers. It integrates with Microsoft Entra ID so users can sign in with existing credentials, simplifying identity and access management for Azure resources and legacy apps.

Prerequisites

  • A site-to-site VPN connection using Microsoft Entra
  • A Microsoft Entra Domain Services domain
  • A QNAP NAS running QTS 5.2.7 (or later) or QuTS hero h5.2.7 (or later)
    Note
    To configure SSO on multiple NAS devices, repeat the steps in this tutorial for each device.

Procedure

To enable Microsoft Entra single sign-on (SSO) on your QNAP NAS, you need to register an application in the Microsoft Entra admin center and then configure SSO settings on the NAS. After setup, users can log in with their Microsoft Entra ID credentials, and you can manage their access and storage privileges directly from the NAS.
