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

  • Article

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

  • Control in Microsoft Entra ID who has access to Splashtop.
  • Enable your users to be automatically signed-in to Splashtop 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.
  • Splashtop 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 Splashtop into Microsoft Entra ID, you need to add Splashtop 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 Splashtop in the search box.
  4. Select Splashtop 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 Splashtop

Configure and test Microsoft Entra SSO with Splashtop 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 Splashtop.

To configure and test Microsoft Entra SSO with Splashtop, 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 Splashtop SSO - to configure the single sign-on settings on application side.
    1. Create Splashtop test user - to have a counterpart of B.Simon in Splashtop 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.

    In the Sign-on URL text box, type the URL: https://my.splashtop.com/login/sso

  6. Splashtop application expects the SAML assertions in a specific format, which requires you to add custom attribute mappings to your SAML token attributes configuration. The following screenshot shows the list of default attributes, whereas nameidentifier is mapped with user.userprincipalname. TicketManager application expects nameidentifier to be mapped with user.mail, so you need to edit the attribute mapping by clicking on Edit icon and change the attribute mapping.
