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

  • Article

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

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

Note

If you are using MFA or Passwordless authentication with Microsoft Entra ID then switch off the AuthnContext value in the SAML Request. Otherwise Microsoft Entra ID will throw the error on mismatch of the AuthnContext and will not send the token back to the application.

Scenario description

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

  • PagerDuty supports SP initiated SSO

To configure the integration of PagerDuty into Microsoft Entra ID, you need to add PagerDuty 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 PagerDuty in the search box.
  4. Select PagerDuty 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 single sign-on for PagerDuty

  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 PagerDuty SSO - to configure the single sign-on settings on application side.
    1. Create PagerDuty test user - to have a counterpart of B.Simon in PagerDuty that is linked to the Microsoft Entra representation of user.
  3. Test SSO - to verify whether the configuration works.
