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

  • מאמר

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

  • Control in Microsoft Entra ID who has access to Harness.
  • Enable your users to be automatically signed-in to Harness 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.
  • Harness single sign-on (SSO) enabled subscription.

Scenario description

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

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

To configure the integration of Harness into Microsoft Entra ID, you need to add Harness 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 Harness in the search box.
  4. Select Harness 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.

Configure and test Microsoft Entra SSO for Harness

Configure and test Microsoft Entra SSO with Harness using a test user called B.Simon. For SSO to work, you need to establish a link relationship between a Microsoft Entra user and the related user in Harness.

To configure and test Microsoft Entra SSO with Harness, perform the following steps:

  1. Configure Microsoft Entra SSO - to enable your users to use this feature.
    1. Create a Microsoft Entra test user - to test Microsoft Entra single sign-on with B.Simon.
    2. Assign the Microsoft Entra test user - to enable B.Simon to use Microsoft Entra single sign-on.
  2. Configure Harness SSO - to configure the single sign-on settings on application side.
    1. Create Harness test user - to have a counterpart of B.Simon in Harness that is linked to the Microsoft Entra representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Microsoft Entra SSO

Follow these steps to enable Microsoft Entra SSO.

Test SSO

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

SP initiated:

  • Go to Harness Sign-on URL directly and initiate the login flow from there.

IDP initiated:

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

You can also use Microsoft My Apps to test the application in any mode. When you click the Harness tile in the My Apps, if configured in SP mode you would be redirected to the application sign on page for initiating the login flow and if configured in IDP mode, you should be automatically signed in to the Harness for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.

Next steps

Once you configure Harness you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Defender for Cloud Apps.
