User Management

Boost productivity and save your IT admins time with intuitive user account and device management across your entire business.

Boost management efficiency

Leverage user and group management tools on Synology DiskStation Manager (DSM) to configure folder permissions, storage quotas, speed limits, and access privileges to software on DSM itself. Additional directory services such as Windows Active Directory (AD) and LDAP can be joined to simplify device management across multiple sites.

Fit into existing environments

Integrate Synology NAS into deployments with a variety of devices and applications, and set access permissions to existing services to ensure efficiency.

Centralize user management

Manage accounts individually or across groups, delegate administrator privileges on DSM, and push critical updates to multiple workstations through Windows AD.

Minimize your expenditure

Eliminate expensive hardware, operating systems, and license fees associated with traditional servers by self-hosting a directory server on Synology NAS.

Running a directory server

Consolidate account and device management with one application.

Synology Directory Server

Synology Directory Server

Transform your Synology system into a centralized domain controller to manage and secure accounts and devices, and to deploy updates or group policies to Windows endpoints.

Windows Active Directory and RSAT support

Manage Windows AD-compatible devices by establishing group access controls and policies through RSAT (Remote Server Administration Tools). Enable hot desking and device sharing by creating roaming user profiles on computers joined to the domain.

Active-active failover setup for high availability

Secure uninterrupted directory services in case of system failure by setting up a secondary domain controller with full administrative rights, or a lower-privileged read-only domain controller (RODC) without admin functions and retaining minimal sensitive login data.


Joining an existing domain

Grant users secure and convenient access to services and resources.

Windows Active Directory/LDAP

Connect Synology NAS to an existing domain to centralize account management and let users access applications without repeatedly entering the same login credentials.

Cloud services

Integrate Synology NAS with Azure Active Directory or Google Cloud Identity to enable single sign-on (SSO) for Synology DSM services.


Manage your directory service in the cloud

Use C2 Identity to centrally manage users and groups, simplify user authentication with a one-time login experience for Software-as-a-Service (SaaS) applications, and effectively manage on-premises Windows and macOS workstations across multiple sites.
