Microsoft Entra SSO integration with SURFconext

  • Article

In this article, you'll learn how to integrate SURFconext with Microsoft Entra ID. SURF connected institutions can use SURFconext to log in to many cloud applications with their institution credentials. When you integrate SURFconext with Microsoft Entra ID, you can:

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

You'll configure and test Microsoft Entra single sign-on for SURFconext in a test environment. SURFconext supports SP initiated single sign-on and 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.

Prerequisites

To integrate Microsoft Entra ID with SURFconext, you need:

Add application and assign a test user

Before you begin the process of configuring single sign-on, you need to add the SURFconext application from the Microsoft Entra gallery. You need a test user account to assign to the application and test the single sign-on configuration.

Add SURFconext from the Microsoft Entra application gallery to configure single sign-on with SURFconext. For more information on how to add application from the gallery, see the Quickstart: Add application from the gallery.

Create and assign Microsoft Entra test user

Follow the guidelines in the create and assign a user account article to create a test user account called B.Simon.

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, and assign roles. The wizard also provides a link to the single sign-on configuration pane. Learn more about Microsoft 365 wizards..

Configure Microsoft Entra SSO

Complete the following steps to enable Microsoft Entra single sign-on.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.

  2. Browse to Identity > Applications > Enterprise applications > SURFconext > Single sign-on.

  3. On the Select a single sign-on method page, select SAML.

  4. On the Set up single sign-on with SAML page, select the pencil icon for Basic SAML Configuration to edit the settings.

  5. On the Basic SAML Configuration section, perform the following steps:

    a. In the Identifier textbox, type one of the following URLs:

    Environment URL

    Environment URL
    Production https://engine.surfconext.nl/authentication/sp/debug
    Staging https://engine.test.surfconext.nl/authentication/sp/debug

  6. SURFconext 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.

    Note

    You can remove or delete these default attributes manually under Additional claims section, if it is not required.

Configure SURFconext SSO

To configure single sign-on on SURFconext side, you need to send the App Federation Metadata Url to SURFconext support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create SURFconext test user

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

Test SSO

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

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

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

  • You can use Microsoft My Apps. When you click the SURFconext tile in the My Apps, this will redirect to SURFconext Sign-on URL. For more information, see Microsoft Entra My Apps.
