Tutorial: Microsoft Entra single sign-on (SSO) integration with OpenAthens

  • Artikkeli

In this tutorial, you'll learn how to integrate OpenAthens with Microsoft Entra ID. When you integrate OpenAthens with Microsoft Entra ID, you can:

  • Control in Microsoft Entra ID who has access to OpenAthens.
  • Enable your users to be automatically signed-in to OpenAthens with their Microsoft Entra accounts.
  • Manage your accounts in one central location.

Prerequisites

To get started, you need the following items:

  • A Microsoft Entra subscription. If you don't have a subscription, you can get a free account.
  • OpenAthens single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Microsoft Entra SSO in a test environment.

  • OpenAthens supports IDP initiated SSO
  • OpenAthens supports Just In Time user provisioning

To configure the integration of OpenAthens into Microsoft Entra ID, you need to add OpenAthens from the gallery to your list of managed SaaS apps.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
  2. Browse to Identity > Applications > Enterprise applications > New application.
  3. In the Add from the gallery section, type OpenAthens in the search box.
  4. Select OpenAthens from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, assign roles, as well as walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.

Test SSO

In this section, you test your Microsoft Entra single sign-on configuration with following options.

  • Click on Test this application, and you should be automatically signed in to the OpenAthens for which you set up the SSO.

  • You can use Microsoft My Apps. When you click the OpenAthens tile in the My Apps, you should be automatically signed in to the OpenAthens for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.
