Tutorial: Azure Active Directory integration with SAP Cloud Platform Identity Authentication

In this tutorial, you learn how to integrate SAP Cloud Platform Identity Authentication with Azure Active Directory (Azure AD). SAP Cloud Platform Identity Authentication is used as a proxy IdP to access SAP applications using Azure AD as the main IdP.

Integrating SAP Cloud Platform Identity Authentication with Azure AD provides you with the following benefits:

  • You can control in Azure AD who has access to SAP Application.
  • You can enable your users to automatically get signed-on to SAP applications single sign-on (SSO)) with their Azure AD accounts.
  • You can manage your accounts in one central location - the Azure portal.

If you want to know more details about SaaS app integration with Azure AD, see what is application access and single sign-on with Azure Active Directory.

Prerequisites

To configure Azure AD integration with SAP Cloud Platform Identity Authentication, you need the following items:

  • An Azure AD subscription
  • An SAP Cloud Platform Identity Authentication single sign-on enabled subscription
Note

To test the steps in this tutorial, we do not recommend using a production environment.

To test the steps in this tutorial, you should follow these recommendations:

  • Do not use your production environment, unless it is necessary.
  • If you don't have an Azure AD trial environment, you can get a one-month trial.

Scenario description

In this tutorial, you test Azure AD single sign-on in a test environment. The scenario outlined in this tutorial consists of two main building blocks:

  1. Adding SAP Cloud Platform Identity Authentication from the gallery
  2. Configuring and testing Azure AD single sign-on

Before diving into the technical details, it is vital to understand the concepts you're going to look at. The SAP Cloud Platform Identity Authentication and Azure Active Directory federation enables you to implement SSO across applications or services protected by AAD (as an IdP) with SAP applications and services protected by SAP Cloud Platform Identity Authentication.

Currently, SAP Cloud Platform Identity Authentication acts as a Proxy Identity Provider to SAP-applications. Azure Active Directory in turn acts as the leading Identity Provider in this setup.

The following diagram illustrates this:

Creating an Azure AD test user

With this setup, your SAP Cloud Platform Identity Authentication tenant will be configured as a trusted application in Azure Active Directory.

All SAP applications and services you want to protect through this way are subsequently configured in the SAP Cloud Platform Identity Authentication management console!

This means that authorization for granting access to SAP applications and services needs to take place in SAP Cloud Platform Identity Authentication for such a setup (as opposed to configuring authorization in Azure Active Directory).

By configuring SAP Cloud Platform Identity Authentication as an application through the Azure Active Directory Marketplace, you don't need to take care of configuring needed individual claims / SAML assertions and transformations needed to produce a valid authentication token for SAP applications.

Note

Currently Web SSO has been tested by both parties, only. Flows needed for App-to-API or API-to-API communication should work but have not been tested, yet. They will be tested as part of subsequent activities.

To configure the integration of SAP Cloud Platform Identity Authentication into Azure AD, you need to add SAP Cloud Platform Identity Authentication from the gallery to your list of managed SaaS apps.

To add SAP Cloud Platform Identity Authentication from the gallery, perform the following steps:

  1. In the Azure portal, on the left navigation panel, click Azure Active Directory icon.

    The Azure Active Directory button

  2. Navigate to Enterprise applications. Then go to All applications.

    The Enterprise applications blade

  3. To add new application, click New application button on the top of dialog.

    The New application button

  4. In the search box, type SAP Cloud Platform Identity Authentication, select SAP Cloud Platform Identity Authentication from result panel then click Add button to add the application.

Configure and test Azure AD single sign-on

In this section, you configure and test Azure AD single sign-on with SAP Cloud Platform Identity Authentication based on a test user called "Britta Simon".

For single sign-on to work, Azure AD needs to know what the counterpart user in SAP Cloud Platform Identity Authentication is to a user in Azure AD. In other words, a link relationship between an Azure AD user and the related user in SAP Cloud Platform Identity Authentication needs to be established.

In SAP Cloud Platform Identity Authentication, assign the value of the user name in Azure AD as the value of the Username to establish the link relationship.

To configure and test Azure AD single sign-on with SAP Cloud Platform Identity Authentication, you need to complete the following building blocks:

  1. Configure Azure AD Single Sign-On - to enable your users to use this feature.
  2. Create an Azure AD test user - to test Azure AD single sign-on with Britta Simon.
  3. Create an SAP Cloud Platform Identity Authentication test user - to have a counterpart of Britta Simon in SAP Cloud Platform Identity Authentication that is linked to the Azure AD representation of user.
  4. Assign the Azure AD test user - to enable Britta Simon to use Azure AD single sign-on.
  5. Test single sign-on - to verify whether the configuration works.

Configure Azure AD single sign-on

In this section, you enable Azure AD single sign-on in the Azure portal and configure single sign-on in your SAP Cloud Platform Identity Authentication application.

To configure Azure AD single sign-on with SAP Cloud Platform Identity Authentication, perform the following steps:

  1. In the Azure portal, on the SAP Cloud Platform Identity Authentication application integration page, click Single sign-on.

    Configure single sign-on link
