Tutorial: Microsoft Entra single sign-on (SSO) integration with SAP Fiori

  • Artikkeli

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

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

Scenario description

In this tutorial, you configure and test Microsoft Entra SSO in a test environment.

  • SAP Fiori supports SP initiated SSO

Note

For SAP Fiori initiated iFrame Authentication, we recommend using the IsPassive parameter in the SAML AuthnRequest for silent authentication. For more details of the IsPassive parameter refer to Microsoft Entra SAML single sign-on information.

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

Configure and test Microsoft Entra SSO with SAP Fiori 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 Fiori.

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

Configure Microsoft Entra SSO

Follow these steps to enable Microsoft Entra SSO.

  1. Open a new web browser window and sign in to your SAP Fiori company site as an administrator.

  2. Make sure that http and https services are active and that the relevant ports are assigned to transaction code SMICM.

  3. Sign in to SAP Business Client for SAP system T01, where single sign-on is required. Then, activate HTTP Security Session Management.

    1. Go to transaction code SICF_SESSIONS. All relevant profile parameters with current values are shown. They look like the following example:

      login/create_sso2_ticket = 2
login/accept_sso2_ticket = 1
login/ticketcache_entries_max = 1000
login/ticketcache_off = 0  login/ticket_only_by_https = 0
icf/set_HTTPonly_flag_on_cookies = 3
icf/user_recheck = 0  http/security_session_timeout = 1800
http/security_context_cache_size = 2500
rdisp/plugin_auto_logout = 1800
rdisp/autothtime = 60

      Note

      Adjust the parameters based on your organization requirements. The preceding parameters are given only as an example.

    2. If necessary, adjust parameters in the instance (default) profile of the SAP system and restart the SAP system.

    3. Double-click the relevant client to enable an HTTP security session.

    4. Activate the following SICF services:

      /sap/public/bc/sec/saml2
/sap/public/bc/sec/cdc_ext_service
/sap/bc/webdynpro/sap/saml2
/sap/bc/webdynpro/sap/sec_diag_tool (This is only to enable / disable trace)

  4. Go to transaction code SAML2 in Business Client for SAP system [T01/122]. The configuration UI opens in a new browser window. In this example, we use Business Client for SAP system 122.

  5. Enter your username and password, and then select Log on.

  6. In the Provider Name box, replace T01122 with http://T01122, and then select Save.

    Note

    By default, the provider name is in the format <sid><client>. Microsoft Entra ID expects the name in the format <protocol>://<name>. We recommend that you maintain the provider name as https://<sid><client> so you can configure multiple SAP Fiori ABAP engines in Microsoft Entra ID.

  7. Select Local Provider tab > Metadata.

  8. In the SAML 2.0 Metadata dialog box, download the generated metadata XML file and save it on your computer.

    3. When the metadata file is successfully uploaded, the Identifier and Reply URL values are automatically populated in the Basic SAML Configuration pane. In the Sign on URL box, enter a URL that has the following pattern: https://<your company instance of SAP Fiori>.

      Note

      Some customers have encountered an error of an incorrect Reply URL configured for their instance. If you receive any such error, use these PowerShell commands. First update the Reply URLs in the application object with the Reply URL, then update the service principal. Use the Get-MgServicePrincipal to get the Service Principal ID value.

      $params = @{
   web = @{
      redirectUris = "<Your Correct Reply URL>"
   }
}
Update-MgApplication -ApplicationId "<Application ID>" -BodyParameter $params
Update-MgServicePrincipal -ServicePrincipalId "<Service Principal ID>" -ReplyUrls "<Your Correct Reply URL>"

  14. The SAP Fiori application expects the SAML assertions to be in a specific format. Configure the following claims for this application. To manage these attribute values, in the Set up Single Sign-On with SAML pane, select Edit.

    The User attributes pane
