Azure Active Directory single sign-on (SSO) integration with ServiceNow

March 29, 2024
In this tutorial, you'll learn how to integrate ServiceNow with Azure Active Directory (Azure AD). When you integrate ServiceNow with Azure AD, you can:
  • Control in Azure AD who has access to ServiceNow.
  • Enable your users to be automatically signed-in to ServiceNow with their Azure AD accounts.
  • Manage your accounts in one central location: the Azure portal.

Pre-Requisites

To get started, you need the following items:
  • An Azure AD 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.

Add ServiceNow from the gallery

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

  1. Sign in to the Azure portal by using either a work or school account, or by using a personal Microsoft account.
  2. In the left pane, select the Azure Active Directory service.
  3. Go to Enterprise Applications, and select All Applications.
  4. To add new application, select New application.
  5. In the Add from the gallery section, enter ServiceNow in the search box.
  6. Select ServiceNow from results panel, and then add the app. Wait a few seconds while the app is added to your tenant.

Configure and test Azure AD SSO for ServiceNow

Configure and test Azure AD SSO with ServiceNow by using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in ServiceNow.

To configure and test Azure AD SSO with ServiceNow, perform the following steps:

  1. Configure Azure AD SSO to enable your users to use this feature.
  2. Create an Azure AD test user to test Azure AD single sign-on with B.Simon.
  3. Assign the Azure AD test user to enable B.Simon to use Azure AD single sign-on.
  4. Configure Azure AD SSO for ServiceNow Express to enable your users to use this feature.
  5. Configure ServiceNow to configure the SSO settings on the application side.
  6. Create a ServiceNow test user to have a counterpart of B.Simon in ServiceNow, linked to the Azure AD representation of the user.
  7. Configure ServiceNow Express SSO to configure the single sign-on settings on the application side.
  8. Test SSO to verify whether the configuration works.
  9. Test SSO for ServiceNow Agent (Mobile) to verify whether the configuration works.



Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

  1. In the Azure portal, on the ServiceNow application integration page, find the Manage section. Select single sign-on.
  2. On the Select a single sign-on method page, select SAML.
  3. On the Set up single sign-on with SAML page, select the pen icon for Basic SAML Configuration to edit the settings.

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

a. In Sign on URL, enter one of the following URL patterns:

Sign on URL

https://<instancename>.service-now.com/navpage.dohttps://<instance-name>.service-now.com/login_with_sso.do?glide_sso_id=<sys_id of the sso configuration>

 Note

Please copy the sys_id value from Configure ServiceNow section which is explained later in the tutorial.


b. In Identifier (Entity ID), enter a URL that uses the following pattern:  https://<instance-name>.service-now.com

c. For Reply URL, enter one of the following URL patterns:

Reply URL

https://<instancename>.service-now.com/navpage.dohttps://<instancename>.service-now.com/consumer.do

d. In Logout URL, enter a URL that uses the following pattern:  https://<instancename>.service-now.com/navpage.do


Note

If "/ " is added in the Identifier value, please remove that manually.

 Note

These values aren't real. You need to update these values with the actual sign-on URL, Reply URL, Logout URL and identifier, which is explained later in the tutorial. You can also refer to the patterns shown in the Basic SAML Configuration section in the Azure portal.

5. On the Set up single sign-on with SAML page, in the SAML Signing Certificate section, find Certificate (Base64).
