About Authentication Services licenses

Authentication Services must be licensed in order for Active Directory users to authenticate on Unix and macOS hosts.

Note: When upgrading, Authentication Services continues to use licenses from previous versions. This allows the upgrade to take place without having to distribute new license files first.

Note: While you can install and configure Authentication Services on Windows and use the included management tools to Unix-enable users and groups in Active Directory without installing a license, you must have a valid Authentication Services license installed for full functionality.

NOTE: In order to use Starling Two-Factor Authentication with Authentication Services, you must have a valid license for Authentication Services with One Identity Hybrid Subscription included.

To obtain a license, use the Licensing Assistance page on the One Identity support page or contact your account representative.

For more information on installing Authentication Services licenses, see Adding licenses using the Control Center.

Supported Windows Platforms

Prerequisite Windows software

If the following prerequisite is missing, the Authentication Services installer suspends the installation process to allow you to download the required component. It then continues the install:

  • Microsoft .NET Framework 4.5

You can install Authentication Services on 64-bit editions of the following configurations:

  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2
  • Windows Server 2016
  • Windows Server 2019

NOTE: Due to tightened security, when running Authentication Services Control Center on Windows 2008 R2 (or later) operating system, functioning as a domain controller, the process must be elevated or you must add authenticated users to the Distributed COM Users group on the computer. As a best practice, One Identity does not recommend that you install or run the Authentication Services Windows components on Active Directory domain controllers. The recommended configuration is to install the Authentication Services Windows components on an administrative workstation.
