Active Directory Integration for TOP Server Configuration and OPC UA Server User Management

Active Directory (AD) integration, added in TOP Server V7.0, empowers organizations to leverage existing Windows domain infrastructure for centralized user authentication and access control to the TOP Server configuration and OPC UA Server interfaces.

Key Benefits

Centralized User Administration - By connecting TOP Server to your Active Directory infrastructure, you eliminate the need to manage duplicate user accounts across multiple systems. Changes to user credentials, group memberships, and permissions made in Active Directory are automatically recognized by TOP Server, reducing administrative overhead and minimizing the risk of inconsistent permissions across your environment.

Enhanced Security - Active Directory integration leverages your organization's existing security policies and password requirements. Domain users and administrators benefit from centralized password management, including enforcement of complexity rules, expiration policies, and account lockout mechanisms. Additionally, TOP Server respects Active Directory group memberships, enabling role-based access control that aligns with your organizational structure.

Simplified Deployment - Organizations with multiple TOP Server installations can provide consistent user access across all instances without manually provisioning accounts on each system. Domain users can authenticate seamlessly whether connecting to the Server Configuration, Server Administration, Configuration API, or OPC UA Server interfaces.

Supported Interfaces

Active Directory user and group authentication is available across multiple TOP Server interfaces:

  • Server Configuration GUI – Full support for AD users and groups
  • Server Administration – Full support for AD users and groups
  • Configuration API – Full support for AD users and groups
  • OPC UA Server – Support for AD users only (not groups)

Technical Requirements

  • Windows Server 2016 or later (for domain controller compatibility)
  • Active Directory domain membership for the TOP Server host computer
  • Network connectivity to at least one domain controller
  • Appropriate user permissions to query Active Directory group membership

When this feature is used with the OPC UA Server interface, the interface supports Active Directory user authentication but does not support group-based access control. Individual AD users must be explicitly configured for this interface.

Get Started Now

The demo is the full product once licensed. Once a client application connects to the  TOP Server, the TOP Server runtime will operate for 2 hours at a time. At the end of the 2 hour demo period, the demo timer must be reset by restarting the TOP Server runtime service.
