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's linked to the Microsoft Entra representation of user.
3. Test SSO - to verify whether the configuration works.

Create and assign Microsoft Entra test user

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

Configure SAP Business Technology Platform SSO

1. In a different web browser window, sign on to the SAP Business Technology Platform Cockpit at https://account.<landscape host>.ondemand.com/cockpit(for example: https://account.hanatrial.ondemand.com/cockpit).

2. Select the Trust tab.

   

3. In the Trust Management section, under Local Service Provider, perform the following steps:

   

   a. Select Edit.

   b. As Configuration Type, select Custom.

   c. As Local Provider Name, leave the default value. Copy this value and paste it into the Identifier field in the Microsoft Entra configuration for SAP Business Technology Platform.

   d. To generate a Signing Key and a Signing Certificate key pair, select Generate Key Pair.

   e. As Principal Propagation, select Disabled.

   f. As Force Authentication, select Disabled.

   g. Select Save.

4. After saving the Local Service Provider settings, perform the following to obtain the Reply URL:

   

   a. Download the SAP Business Technology Platform metadata file by selecting Get Metadata.

   b. Open the downloaded SAP Business Technology Platform metadata XML file, and then locate the ns3:AssertionConsumerService tag.

   c. Copy the value of the Location attribute, and then paste it into the Reply URL field in the Microsoft Entra configuration for SAP Business Technology Platform.

5. Select the Trusted Identity Provider tab, and then select Add Trusted Identity Provider.

   

   ملاحظة

   To manage the list of trusted identity providers, you need to have chosen the Custom configuration type in the Local Service Provider section. For Default configuration type, you have a non-editable and implicit trust to the SAP ID Service. For None, you don't have any trust settings.

6. Select the General tab, and then select Browse to upload the downloaded metadata file.

   

   ملاحظة

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

7. Select the Attributes tab.

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

   

   a. Select 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

   ملاحظة

   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 isn't 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's 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:

   

   a. Select Authorization.

   b. Select the Users tab.

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

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

   e. Select Save.

Test SSO

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

• Select Test this application, this option redirects 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 select 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.
