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

  • Članak

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

  • Control in Microsoft Entra ID who has access to ServiceNow.
  • Enable your users to be automatically signed-in to ServiceNow with their Microsoft Entra accounts.
  • Manage your accounts in one central location: the Azure portal.

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.
  • A ServiceNow single sign-on (SSO) enabled subscription.
  • For ServiceNow, an instance or tenant of ServiceNow supports Calgary, Kingston, London, Madrid, New York, Orlando, Paris and San Diego versions or later.
  • For ServiceNow Express, an instance of ServiceNow Express, Helsinki version or later.
  • The ServiceNow tenant must have the Multiple Provider Single Sign On Plugin enabled.
  • For automatic configuration, enable the multi-provider plugin for ServiceNow.
  • To install the ServiceNow Agent (Mobile) application, go to the appropriate store, and search for the ServiceNow Agent application. Then download it.

Note

This integration is also available to use from Microsoft Entra US Government Cloud environment. You can find this application in the Microsoft Entra US Government Cloud Application Gallery and configure it in the same way as you do from public cloud.

Scenario description

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

  • ServiceNow supports SP initiated SSO.

  • ServiceNow supports Automated user provisioning.

  • You can configure the ServiceNow Agent (Mobile) application with Microsoft Entra ID for enabling SSO. It supports both Android and iOS users. In this tutorial, you configure and test Microsoft Entra SSO in a test environment.

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

Configure and test Microsoft Entra SSO with ServiceNow by 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 ServiceNow.

To configure and test Microsoft Entra SSO with ServiceNow, 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.
    3. Configure Microsoft Entra SSO for ServiceNow Express to enable your users to use this feature.
  2. Configure ServiceNow to configure the SSO settings on the application side.
    1. Create a ServiceNow test user to have a counterpart of B.Simon in ServiceNow, linked to the Microsoft Entra representation of the user.
    2. Configure ServiceNow Express SSO to configure the single sign-on settings on the application side.
  3. Test SSO to verify whether the configuration works.
  4. Test SSO for ServiceNow Agent (Mobile) 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 > ServiceNow application integration page, find the Manage section. Select 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, select the pen icon for Basic SAML Configuration to edit the settings.
