Tutorial: Microsoft Entra SSO integration with SAP Business Technology Platform

  • Artículo

In this tutorial, you'll learn how to integrate SAP Business Technology Platform with Microsoft Entra ID. When you integrate SAP Business Technology Platform with Microsoft Entra ID, you can:

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

Important

You need to deploy your own application or subscribe to an application on your SAP Business Technology Platform account to test single sign on. In this tutorial, an application is deployed in the account.

Scenario description

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

  • SAP Business Technology Platform supports SP initiated SSO.

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

Configure and test Microsoft Entra SSO with SAP Business Technology Platform 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 SAP Business Technology Platform.

To configure and test Microsoft Entra SSO with SAP Business Technology Platform, 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 Britta Simon.
    2. Assign the Microsoft Entra test user - to enable Britta Simon to use Microsoft Entra single sign-on.
  2. Configure SAP Business Technology Platform SSO - to configure the Single Sign-On settings on application side.
    1. Create SAP Business Technology Platform test user - to have a counterpart of Britta Simon in SAP Business Technology Platform that is linked to the Microsoft Entra representation of user.
  3. Test SSO - to verify whether the configuration works.

    Trust Management

    Note

    After uploading the metadata file, the values for Single Sign-on URL, Single Logout URL, and Signing Certificate are populated automatically.

  7. Click the Attributes tab.

  8. On the Attributes tab, perform the following step:

    Attributes

    a. Click Add Assertion-Based Attribute, and then add the following assertion-based attributes:

    Assertion Attribute Principal Attribute
    http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname firstname
    http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname lastname
    http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress email

    Note

    The configuration of the Attributes depends on how the application(s) on SCP are developed, that is, which attribute(s) they expect in the SAML response and under which name (Principal Attribute) they access this attribute in the code.

    b. The Default Attribute in the screenshot is just for illustration purposes. It is not required to make the scenario work.

    c. The names and values for Principal Attribute shown in the screenshot depend on how the application is developed. It is possible that your application requires different mappings.

Assertion-based groups

As an optional step, you can configure assertion-based groups for your Microsoft Entra identity Provider.

Using groups on SAP Business Technology Platform allows you to dynamically assign one or more users to one or more roles in your SAP Business Technology Platform applications, determined by values of attributes in the SAML 2.0 assertion.

For example, if the assertion contains the attribute "contract=temporary", you may want all affected users to be added to the group "TEMPORARY". The group "TEMPORARY" may contain one or more roles from one or more applications deployed in your SAP Business Technology Platform account.

Use assertion-based groups when you want to simultaneously assign many users to one or more roles of applications in your SAP Business Technology Platform account. If you want to assign only a single or small number of users to specific roles, we recommend assigning them directly in the “Authorizations” tab of the SAP Business Technology Platform cockpit.

Create SAP Business Technology Platform test user

In order to enable Microsoft Entra users to log in to SAP Business Technology Platform, you must assign roles in the SAP Business Technology Platform to them.

To assign a role to a user, perform the following steps:

  1. Log in to your SAP Business Technology Platform cockpit.

  2. Perform the following:

    Authorizations

    a. Click Authorization.

    b. Click the Users tab.

    c. In the User textbox, type the user’s email address.

    d. Click Assign to assign the user to a role.

    e. Click Save.

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 SAP Business Technology Platform Sign-on URL where you can initiate the login flow.

  • Go to SAP Business Technology Platform Sign-on URL directly and initiate the login flow from there.

  • You can use Microsoft My Apps. When you click the SAP Business Technology Platform tile in the My Apps, you should be automatically signed in to the SAP Business Technology Platform 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 SAP Business Technology Platform 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.
