Tutorial: Microsoft Entra SSO integration with IBMid

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

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.
• IBMid single sign-on (SSO) enabled subscription.

Scenario description

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

• IBMid supports SP and IDP initiated SSO.
• IBMid supports Just In Time user provisioning.

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

Add IBMid from the gallery

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

Configure and test Microsoft Entra SSO with IBMid 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 IBMid.

To configure and test Microsoft Entra SSO with IBMid, 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 IBMid SSO - to configure the single sign-on settings on application side.
   1. Create IBMid test user - to have a counterpart of B.Simon in IBMid 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. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.

2. Browse to Identity > Applications > Enterprise applications > IBMid > Single sign-on.

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

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

6. 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 the URL: https://login.ibm.com

7. Click Save.

8. IBMid 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.

   

9. In addition to above, IBMid 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.

Configure IBMid SSO

To configure single sign-on on IBMid side, you need to send the downloaded Federation Metadata XML and appropriate copied URLs from the application configuration to IBMid support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create IBMid test user

In this section, a user called Britta Simon is created in IBMid. IBMid supports just-in-time user provisioning, which is enabled by default. There is no action item for you in this section. If a user doesn't already exist in IBMid, a new one is created after authentication.

Test SSO

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

SP initiated:

• Click on Test this application, this will redirect to IBMid Sign on URL where you can initiate the login flow.

• Go to IBMid Sign-on URL directly and initiate the login flow from there.

IDP initiated:

• Click on Test this application, and you should be automatically signed in to the IBMid 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 IBMid 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 IBMid for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.

Next steps

Once you configure IBMid you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Defender for Cloud Apps.
