Tutorial: Azure Active Directory single sign-on (SSO) integration with Perimeter 81

In this tutorial, you'll learn how to integrate Perimeter 81 with Azure Active Directory (Azure AD). When you integrate Perimeter 81 with Azure AD, you can:

  • Control in Azure AD who has access to Perimeter 81.
  • Enable your users to be automatically signed-in to Perimeter 81 with their Azure AD accounts.
  • Manage your accounts in one central location - the Azure portal.


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.
  • Perimeter 81 single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Azure AD SSO in a test environment.

  • Perimeter 81 supports SP and IDP initiated SSO
  • Perimeter 81 supports Just In Time user provisioning

To configure the integration of Perimeter 81 into Azure AD, you need to add Perimeter 81 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 Perimeter 81 in the search box.
  6. Select Perimeter 81 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 Perimeter 81

Configure and test Azure AD SSO with Perimeter 81 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 Perimeter 81.

To configure and test Azure AD SSO with Perimeter 81, perform the following steps:

  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 Perimeter 81 SSO - to configure the single sign-on settings on application side.
    1. Create Perimeter 81 test user - to have a counterpart of B.Simon in Perimeter 81 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 Perimeter 81 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.

    Edit Basic SAML Configuration

  4. On the Basic SAML Configuration section, if you wish to configure the application in IDP initiated mode, enter the values for the following fields:

    a. In the Identifier text box, type a value using the following pattern: urn:auth0:perimeter81:<SUBDOMAIN>

    b. In the Reply URL text box, type a URL using the following pattern: https://auth.perimeter81.com/login/callback?connection=<SUBDOMAIN>

  5. 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 a URL using the following pattern: https://<SUBDOMAIN>.perimeter81.com


    These values are not real. Update these values with the actual Identifier, Reply URL and Sign-on URL. Contact Perimeter 81 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.

  6. 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.

    c. Open the downloaded Certificate (Base64) from the Azure portal into Notepad and paste the content into the X509 Signing Certificate textbox.


    Alternatively you can click on Upload PEM/CERT File to upload the Certificate (Base64) which you downloaded from Azure portal.

    d. Click Done.

Create Perimeter 81 test user

In this section, a user called Britta Simon is created in Perimeter 81. Perimeter 81 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 Perimeter 81, a new one is created after authentication.

Test SSO

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

SP initiated:

  • Click on Test this application in Azure portal. This will redirect to Perimeter 81 Sign on URL where you can initiate the login flow.

  • Go to Perimeter 81 Sign-on URL directly and initiate the login flow from there.

IDP initiated:

  • Click on Test this application in Azure portal and you should be automatically signed in to the Perimeter 81 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 Perimeter 81 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 Perimeter 81 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 Perimeter 81 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 Cloud App Security.
