Tutorial: Azure Active Directory single sign-on (SSO) integration with PagerDuty

In this tutorial, you'll learn how to integrate PagerDuty with Azure Active Directory (Azure AD). When you integrate PagerDuty with Azure AD, you can:

  • Control in Azure AD who has access to PagerDuty.
  • Enable your users to be automatically signed-in to PagerDuty with their Azure AD accounts.
  • Manage your accounts in one central location - the Azure portal.

Prerequisites

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

Note

If you are using MFA or Passwordless authentication with Azure AD then switch off the AuthnContext value in the SAML Request. Otherwise Azure AD 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 Azure AD SSO in a test environment.

  • PagerDuty supports SP initiated SSO

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

  1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
  2. On the left navigation pane, select the Azure Active Directory service.
  3. Navigate to Enterprise Applications and then select All Applications.
  4. To add new application, select New application.
  5. In the Add from the gallery section, type PagerDuty in the search box.
  6. 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 Azure AD single sign-on for PagerDuty

Configure and test Azure AD SSO with PagerDuty 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 PagerDuty.

To configure and test Azure AD SSO with PagerDuty, complete the following building blocks:

  1. Configure Azure AD SSO - to enable your users to use this feature.
    1. Create an Azure AD test user - to test Azure AD single sign-on with B.Simon.
    2. Assign the Azure AD test user - to enable B.Simon to use Azure AD 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 Azure AD representation of user.
  3. Test SSO - 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 PagerDuty application integration page, find the Manage section and 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, click the pencil icon for Basic SAML Configuration to edit the settings.

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

    a. In the Sign on URL text box, type a URL using the following pattern: https://<tenant-name>.pagerduty.com

    b. In the Identifier (Entity ID) text box, type a URL using the following pattern: https://<tenant-name>.pagerduty.com

    c. In the Reply URL text box, type a URL using the following pattern: https://<tenant-name>.pagerduty.com

    Note

    These values are not real. Update these values with the actual Sign on URL, Identifier and Reply URL. Contact PagerDuty Client support team to get these values. 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) and select Download to download the certificate and save it on your computer.

    3. Select the Show password check box, and then write down the value that's displayed in the Password box.
    4. Click Create.

Assign the Azure AD test user

In this section, you'll enable B.Simon to use Azure single sign-on by granting access to PagerDuty.

  1. In the Azure portal, select Enterprise Applications, and then select All applications.
  2. In the applications list, select PagerDuty.
  3. In the app's overview page, find the Manage section and select Users and groups.
  4. Select Add user, then select Users and groups in the Add Assignment dialog.
  5. In the Users and groups dialog, select B.Simon from the Users list, then click the Select button at the bottom of the screen.
  6. If you're expecting any role value in the SAML assertion, in the Select Role dialog, select the appropriate role for the user from the list and then click the Select button at the bottom of the screen.

    e. Select Require EXACT authentication context comparison checkbox.

    f. Click Save Changes.

Create PagerDuty test user

To enable Azure AD users to sign into PagerDuty, they must be provisioned into PagerDuty. In the case of PagerDuty, provisioning is a manual task.

    c. Click Add, and then click Send Invites.

    Note

    All added users will receive an invite to create a PagerDuty account.

Test SSO

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

  • Click on Test this application in Azure portal. This will redirect to PagerDuty Sign-on URL where you can initiate the login flow.

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

  • You can use Microsoft My Apps. When you click the PagerDuty tile in the My Apps, this will redirect to PagerDuty Sign-on URL. For more information about the My Apps, see Introduction to the My Apps.

Next steps

Once you configure PagerDuty 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.
