Windows SSO integration with Active Directory
This topic is an outline of how to configure Windows single sign-on (SSO) in the SecureAuth® Identity Platform.
To allow secure access to your integrated resources using Windows SSO, it connects with the SecureAuth Integrated Windows Authentication (IWA) service for Kerberos-based authentication.
Prerequisites
Identity Platform release 24.04 or later, cloud deployment
Active Directory (AD) data store
Active Directory (AD) service account with least privilege access for Windows SSO integration in the Identity Platform
Client workstations must be joined to same Active Directory domain
Process
To set up Windows SSO in the Identity Platform, you'll need the following:
- In your AD service account, have a Service Principal Name (SPN) assigned
In your Active Directory (AD), assign an SPN to an AD service account. This the AD service account used for a secure connection between AD and SecureAuth IWA service.
See Configure Active Directory service account for SecureAuth IWA service.
- In AD data store settings, turn on Windows SSO integration
In the Identity Platform data store settings for AD, in the SecureAuth IWA Service Settings section, turn on Allow Windows SSO integration.
- In the authentication policy, use "Run Windows SSO" as a condition
In the Identity Platform authentication policy, go to the Authentication Rules tab. Apply Run Windows SSO as a condition to an authentication rule like Country, IP Range, or Threat Service.
See Policy configuration - Authentication rules.
Note
You can only have one "Run Windows SSO" conditional rule in a policy.
- Set up browser configurations to allow Windows SSO
To enable Windows SSO in your organization's network, you could push out a local intranet URL via Group Policy Object (GPO). Most browsers work with Windows SSO, but you can do some configurations as appropriate for your environment.
