Tutorial: Azure Active Directory single sign-on (SSO) integration with SAP Cloud Platform Identity Authentication

In this tutorial, you'll learn how to integrate SAP Cloud Platform Identity Authentication with Azure Active Directory (Azure AD). When you integrate SAP Cloud Platform Identity Authentication with Azure AD, you can:

• Control in Azure AD who has access to SAP Cloud Platform Identity Authentication.
• Enable your users to be automatically signed-in to SAP Cloud Platform Identity Authentication with their Azure AD accounts.
• Manage your accounts in one central location - the Azure portal.

Prerequisites

To get started, you need the following items:

• An Azure AD subscription. If you don't have a subscription, you can get a free account.
• SAP Cloud Platform Identity Authentication single sign-on (SSO) enabled subscription.

Scenario description

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

• SAP Cloud Platform Identity Authentication supports SP and IDP initiated SSO.
• SAP Cloud Platform Identity Authentication supports Automated user provisioning.

Before you dive into the technical details, it's vital to understand the concepts you're going to look at. The SAP Cloud Platform Identity Authentication and Active Directory Federation Services enable you to implement SSO across applications or services that are protected by Azure AD (as an IdP) with SAP applications and services that are 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 relationship:

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

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

Therefore, the authorization for granting access to SAP applications and services needs to take place in SAP Cloud Platform Identity Authentication (as opposed to Azure Active Directory).

By configuring SAP Cloud Platform Identity Authentication as an application through the Azure Active Directory Marketplace, you don't need to configure individual claims or SAML assertions.

Note

Currently only Web SSO has been tested by both parties. The flows that are necessary for App-to-API or API-to-API communication should work but have not been tested yet. They will be tested during subsequent activities.

Adding SAP Cloud Platform Identity Authentication from the gallery

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.

1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
2. On the left navigation pane, select the Azure Active Directory service.
3. Navigate to Enterprise Applications and then select All Applications.
4. To add new application, select New application.
5. In the Add from the gallery section, type SAP Cloud Platform Identity Authentication in the search box.
6. Select SAP Cloud Platform Identity Authentication from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Configure and test Azure AD SSO for SAP Cloud Platform Identity Authentication

Configure and test Azure AD SSO with SAP Cloud Platform Identity Authentication using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in SAP Cloud Platform Identity Authentication.

To configure and test Azure AD SSO with SAP Cloud Platform Identity Authentication, perform the following steps:

1. Configure Azure AD SSO - to enable your users to use this feature.
   1. Create an Azure AD test user - to test Azure AD single sign-on with B.Simon.
   2. Assign the Azure AD test user - to enable B.Simon to use Azure AD single sign-on.
2. Configure SAP Cloud Platform Identity Authentication SSO - to configure the single sign-on settings on application side.
   1. Create SAP Cloud Platform Identity Authentication test user - to have a counterpart of B.Simon in SAP Cloud Platform Identity Authentication that is linked to the Azure AD representation of user.
3. Test SSO - to verify whether the configuration works.

Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

1. In the Azure portal, on the SAP Cloud Platform Identity Authentication application integration page, find the Manage section and select single sign-on.

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

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

   

4. On the Basic SAML Configuration section, if you wish to configure in IDP-initiated mode, perform the following steps:

   a. In the Identifier text box, type a value using the following pattern: <IAS-tenant-id>.accounts.ondemand.com

   b. In the Reply URL text box, type a URL using the following pattern: https://<IAS-tenant-id>.accounts.ondemand.com/saml2/idp/acs/<IAS-tenant-id>.accounts.ondemand.com

   Note

   These values are not real. Update these values with the actual Identifier and Reply URL. Contact the SAP Cloud Platform Identity Authentication Client support team to get these values. If you don't understand Identifier value, read the SAP Cloud Platform Identity Authentication documentation about Tenant SAML 2.0 configuration.

5. Click Set additional URLs and perform the following step if you wish to configure the application in SP-initiated mode:

   

   In the Sign-on URL text box, type a value using the following pattern: {YOUR BUSINESS APPLICATION URL}

   Note

   This value is not real. Update this value with the actual sign-on URL. Please use your specific business application Sign-on URL. Contact the SAP Cloud Platform Identity Authentication Client support team if you have any doubt.

6. SAP Cloud Platform Identity Authentication 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.

   

7. In addition to above, SAP Cloud Platform Identity Authentication application expects few more attributes to be passed back in SAML response which are shown below. These attributes are also pre populated but you can review them as per your requirements.

   Name	Source Attribute
   firstName	user.givenname

8. On the Set up Single Sign-On with SAML page, in the SAML Signing Certificate section, click Download to download the Metadata XML from the given options as per your requirement and save it on your computer.

   

9. On the Set up SAP Cloud Platform Identity Authentication section, copy the appropriate URL(s) as per your requirement.

7. In the Add Assignment dialog, click the Assign button.

Configure SAP Cloud Platform Identity Authentication SSO

1. To automate the configuration within SAP Cloud Platform Identity Authentication, you need to install My Apps Secure Sign-in browser extension by clicking Install the extension.

   

2. After adding extension to the browser, click on Set up SAP Cloud Platform Identity Authentication will direct you to the SAP Cloud Platform Identity Authentication application. From there, provide the admin credentials to sign into SAP Cloud Platform Identity Authentication. The browser extension will automatically configure the application for you and automate steps 3-7.

   

3. If you want to setup SAP Cloud Platform Identity Authentication manually, in a different web browser window, go to the SAP Cloud Platform Identity Authentication administration console. The URL has the following pattern: https://<tenant-id>.accounts.ondemand.com/admin. Then read the documentation about SAP Cloud Platform Identity Authentication at Integration with Microsoft Azure AD.

4. In the Azure portal, select the Save button.

5. Continue with the following only if you want to add and enable SSO for another SAP application. Repeat the steps under the section Adding SAP Cloud Platform Identity Authentication from the gallery.

6. In the Azure portal, on the SAP Cloud Platform Identity Authentication application integration page, select Linked Sign-on.

   

7. Save the configuration.

Note

The new application leverages the single sign-on configuration of the previous SAP application. Make sure you use the same Corporate Identity Providers in the SAP Cloud Platform Identity Authentication administration console.

Create SAP Cloud Platform Identity Authentication test user

You don't need to create a user in SAP Cloud Platform Identity Authentication. Users who are in the Azure AD user store can use the SSO functionality.

SAP Cloud Platform Identity Authentication supports the Identity Federation option. This option allows the application to check whether users who are authenticated by the corporate identity provider exist in the user store of SAP Cloud Platform Identity Authentication.

The Identity Federation option is disabled by default. If Identity Federation is enabled, only the users that are imported in SAP Cloud Platform Identity Authentication can access the application.

For more information about how to enable or disable Identity Federation with SAP Cloud Platform Identity Authentication, see "Enable Identity Federation with SAP Cloud Platform Identity Authentication" in Configure Identity Federation with the User Store of SAP Cloud Platform Identity Authentication.

Note

SAP Cloud Platform Identity Authentication also supports automatic user provisioning, you can find more details here on how to configure automatic user provisioning.

Test SSO

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

SP initiated:

• Click on Test this application in Azure portal. This will redirect to SAP Cloud Platform Identity Authentication Sign on URL where you can initiate the login flow.

• Go to SAP Cloud Platform Identity Authentication Sign-on URL directly and initiate the login flow from there.

IDP initiated:

• Click on Test this application in Azure portal and you should be automatically signed in to the SAP Cloud Platform Identity Authentication for which you set up the SSO

You can also use Microsoft My Apps to test the application in any mode. When you click the SAP Cloud Platform Identity Authentication tile in the My Apps, if configured in SP mode you would be redirected to the application sign on page for initiating the login flow and if configured in IDP mode, you should be automatically signed in to the SAP Cloud Platform Identity Authentication for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.
