Tutorial: Microsoft Entra integration with LaunchDarkly

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

• Control in Microsoft Entra ID who has access to LaunchDarkly.

• Enable your users to be automatically signed-in to LaunchDarkly with their Microsoft Entra accounts.

• Manage your accounts in one central location.

  Note

  The LaunchDarkly Microsoft Entra integration is one-way. After you configure the integration, you can use Microsoft Entra ID to manage users, SSO, and accounts in LaunchDarkly, but you cannot use LaunchDarkly to manage users, SSO, and accounts in Azure.

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.
• LaunchDarkly single sign-on enabled subscription.

Scenario description

In this tutorial, you configure and test Microsoft Entra single sign-on in a test environment.

• LaunchDarkly supports IDP initiated SSO.
• LaunchDarkly supports Just In Time user provisioning.

Note

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

Add LaunchDarkly from the gallery

To configure the integration of LaunchDarkly into Microsoft Entra ID, you need to add LaunchDarkly 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.

3. In the Add from the gallery section, type LaunchDarkly in the search box.

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.
