Tutorial: Microsoft Entra SSO integration with Palantir Foundry

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

• Control in Microsoft Entra ID who has access to Palantir Foundry.
• Enable your users to be automatically signed-in to Palantir Foundry 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.
• Palantir Foundry single sign-on (SSO) enabled subscription.
• Along with Cloud Application Administrator, Application Administrator can also add or manage applications in Microsoft Entra ID. For more information, see Azure built-in roles.

Note

This integration is also available to use from Microsoft Entra US Government Cloud environment. You can find this application in the Microsoft Entra US Government Cloud Application Gallery and configure it in the same way as you do from public cloud.

Scenario description

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

• Palantir Foundry supports SP and IDP initiated SSO.
• Palantir Foundry supports Just In Time user provisioning.

Add Palantir Foundry from the gallery

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

To configure and test Microsoft Entra SSO with Palantir Foundry, 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 Palantir Foundry SSO - to configure the single sign-on settings on application side.
   1. Create Palantir Foundry test user - to have a counterpart of B.Simon in Palantir Foundry that is linked to the Microsoft Entra representation of user.
3. Test SSO - to verify whether the configuration works.

Create Palantir Foundry test user

In this section, a user called Britta Simon is created in Palantir Foundry. Palantir Foundry supports just-in-time user provisioning, which is enabled by default. There is no action item for you in this section. If a user doesn't already exist in Palantir Foundry, a new one is created after authentication.

Test SSO

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

SP initiated:

• Click on Test this application, this will redirect to Palantir Foundry Sign-on URL where you can initiate the login flow.

• Go to Palantir Foundry 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 Palantir Foundry 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 Palantir Foundry 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 Palantir Foundry for which you set up the SSO. For more information, see Microsoft Entra My Apps.

Next steps

Once you configure Palantir Foundry 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 Cloud App Security.
