Tutorial: Microsoft Entra single sign-on (SSO) integration with FAX.PLUS

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

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

Scenario description

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

  • FAX.PLUS supports SP and IDP initiated SSO.
  • FAX.PLUS supports Just In Time user provisioning.

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

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

    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 FAX.PLUS SSO - to configure the single sign-on settings on application side.
    1. Create FAX.PLUS test user - to have a counterpart of B.Simon in FAX.PLUS that is linked to the Microsoft Entra representation of user.

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

Test SSO

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

SP initiated:

  • Click on Test this application, this will redirect to FAX.PLUS Sign on URL where you can initiate the login flow.

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

IDP initiated:

  • Click on Test this application, and you should be automatically signed in to the FAX.PLUS 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 FAX.PLUS 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 FAX.PLUS 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 FAX.PLUS 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.
