Tutorial: Azure Active Directory integration with SAP Cloud Platform

In this tutorial, you learn how to integrate SAP Cloud Platform with Azure Active Directory (Azure AD). Integrating SAP Cloud Platform with Azure AD provides you with the following benefits:

  • You can control in Azure AD who has access to SAP Cloud Platform.
  • You can enable your users to be automatically signed-in to SAP Cloud Platform (Single Sign-On) 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. If you don't have an Azure subscription, create a free account before you begin.

Prerequisites

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

  • An Azure AD subscription. If you don't have an Azure AD environment, you can get one-month trial here
  • SAP Cloud Platform single sign-on enabled subscription

After completing this tutorial, the Azure AD users you have assigned to SAP Cloud Platform will be able to single sign into the application using the Introduction to the Access Panel.

Important

You need to deploy your own application or subscribe to an application on your SAP Cloud 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 Azure AD single sign-on in a test environment.

  • SAP Cloud Platform supports SP initiated SSO

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

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

Configure and test Azure AD single sign-on

In this section, you configure and test Azure AD single sign-on with SAP Cloud Platform based on a test user called Britta Simon. For single sign-on to work, a link relationship between an Azure AD user and the related user in SAP Cloud Platform needs to be established.

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

  1. Configure Azure AD Single Sign-On - to enable your users to use this feature.
  2. Configure SAP Cloud Platform Single Sign-On - to configure the Single Sign-On settings on application side.
  3. Create an Azure AD test user - to test Azure AD single sign-on with Britta Simon.
  4. Assign the Azure AD test user - to enable Britta Simon to use Azure AD single sign-on.
  5. Create SAP Cloud Platform test user - to have a counterpart of Britta Simon in SAP Cloud Platform that is linked to the Azure AD representation of user.
  6. 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.

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

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

    Configure single sign-on link

  2. On the Select a Single sign-on method dialog, select SAML/WS-Fed mode to enable single sign-on.

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

    SAP Cloud Platform Domain and URLs single sign-on information

    a. In the Sign On URL textbox, type the URL used by your users to sign into your SAP Cloud Platform application. This is the account-specific URL of a protected resource in your SAP Cloud Platform application. The URL is based on the following pattern: https://<applicationName><accountName>.<landscape host>.ondemand.com/<path_to_protected_resource>

    Note

    This is the URL in your SAP Cloud Platform application that requires the user to authenticate.

    https://<subdomain>.hanatrial.ondemand.com/<instancename>
    https://<subdomain>.hana.ondemand.com/<instancename>

    b. In the Identifier textbox you will provide your SAP Cloud Platform's type a URL using one of the following patterns:

    https://hanatrial.ondemand.com/<instancename>
    https://hana.ondemand.com/<instancename>
    https://us1.hana.ondemand.com/<instancename>
    https://ap1.hana.ondemand.com/<instancename>

    c. In the Reply URL textbox, type a URL using the following pattern:

    https://<subdomain>.hanatrial.ondemand.com/<instancename>
    https://<subdomain>.hana.ondemand.com/<instancename>
    https://<subdomain>.us1.hana.ondemand.com/<instancename>
    https://<subdomain>.dispatcher.us1.hana.ondemand.com/<instancename>
    https://<subdomain>.ap1.hana.ondemand.com/<instancename>
    https://<subdomain>.dispatcher.ap1.hana.ondemand.com/<instancename>
    https://<subdomain>.dispatcher.hana.ondemand.com/<instancename>

    Note

    These values are not real. Update these values with the actual Sign-On URL, Identifier, and Reply URL. Contact SAP Cloud Platform Client support team to get Sign-On URL and Identifier. Reply URL you can get from trust management section which is explained later in the tutorial.

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

Configure SAP Cloud Platform Single Sign-On

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

  2. Click the Trust tab.

    Trust

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

    Trust Management

    a. Click 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 Azure AD configuration for SAP Cloud Platform.

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

    e. As Principal Propagation, select Disabled.

    f. As Force Authentication, select Disabled.

    g. Click Save.

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

    Get Metadata

    a. Download the SAP Cloud Platform metadata file by clicking Get Metadata.

    b. Open the downloaded SAP Cloud 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 Azure AD configuration for SAP Cloud Platform.

  5. Click the Trusted Identity Provider tab, and then click Add Trusted Identity Provider.

    Trust Management

    Note

    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. Click the General tab, and then click Browse to upload the downloaded metadata file.

    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 Azure Active Directory Identity Provider.

Using groups on SAP Cloud Platform allows you to dynamically assign one or more users to one or more roles in your SAP Cloud 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 Cloud Platform account.

Use assertion-based groups when you want to simultaneously assign many users to one or more roles of applications in your SAP Cloud 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 Cloud Platform cockpit.
