Palo Alto Networks GlobalProtect Integration with AuthPoint

Deployment Overview

This document describes how to set up AuthPoint multi-factor authentication (MFA) for Palo Alto Networks GlobalProtect. GlobalProtect must already be configured and deployed before you set up MFA with AuthPoint.

Integration Summary

The hardware and software used in this guide include:

  • Palo Alto PA-220 v9.1.2-h1
  • GlobalProtect v5.1.3-12
  • AuthPoint Gateway v5.3.1

Palo Alto Configuration for RADIUS Authentication

AuthPoint communicates with various cloud-based services and service providers with the RADIUS protocol. This diagram shows an overview of the configuration required for RADIUS authentication.

Configure AuthPoint

Before AuthPoint can receive authentication requests from GlobalProtect, you must configure a RADIUS client resource in AuthPoint. You must also assign an access policy for the GlobalProtect RADIUS client resource to the AuthPoint group(s) that will use MFA.

Add a RADIUS Resource in AuthPoint

From the AuthPoint management UI:

  1. From the navigation menu, select Resources.
  2. From the Choose a Resource Type drop-down list, select RADIUS Client. Click Add Resource.

  1. On the RADIUS Client page, in the Name text box, type a name for this resource.
  2. In the RADIUS client trusted IP or FQDN text box, type the Palo Alto internal interface IP address.
  3. In the Value sent for RADIUS attribute 11 (Filter-Id) drop-down list, select User's AuthPoint group.
  4. In the Shared Secret text box, type the shared secret that you configured in the Configure RADIUS Service section.

  1. Click Save.

Add an Access Policy to AuthPoint

You must have at least one user group in AuthPoint for authentication with GlobalProtect, and you must assign an access policy for the GlobalProtect resource to that group. If you already have a group, you do not have to add another group.

In the AuthPoint management UI:

  1. From the navigation menu, select Groups.
  2. To add a new group, click Add Group. If you already have a group that you want to use, click the Name of your group to edit it.

  1. In the Name text box, type a descriptive name for the group.
  2. (Optional) In the Description text box, type a description of the group.

  1. In the Access Policy section, click Add Policy.

  1. In the Add Policy dialog box, from the Resource drop-down list, select the resource you want to add an access policy for.
  2. (Optional) To require that users type their password before they authenticate for this resource, select the Require Password Authentication toggle.
  3. Select the authentication options users in this group can choose from when they authenticate.

    For RADIUS resources, you can only choose OTP or Push. RADIUS resources cannot use the QR code authentication option.

  1. Click Add.
    The access policy for your resource is added to the list.

  1. Click Save.

Bind the RADIUS Resource to a Gateway

To use RADIUS authentication with AuthPoint, you must have the AuthPoint Gateway installed on your corporate network and you must assign your RADIUS resources to the Gateway in the AuthPoint management UI. The Gateway functions as a RADIUS server.

If you have not already configured and installed the AuthPoint Gateway, see About Gateways.

To assign your RADIUS resources to the Gateway:

  1. From the navigation menu, select Gateway.
  2. Select the Name of the Gateway.
  3. In the RADIUS section, in the Port text box, type the port number used to communicate with the Gateway. The default ports are 1812 and 1645.
  4. In the Select a RADIUS resource drop-down list, select your RADIUS client resource.
  5. Click Save.

Add Users to AuthPoint

Before you assign users to a group, you must add the users to AuthPoint. There are two ways to add AuthPoint user accounts:

  • Sync users from an external user database
  • Add local AuthPoint users

Each user must be a member of a group. You must add at least one group before you can add users to AuthPoint.

Test the Integration

To test AuthPoint MFA with Palo Alto GlobalProtect, you can authenticate with a token on your mobile device. For RADIUS resources, you authenticate with a one-time password (OTP) or a push notification. The authentication method you use is determined by the access policy for your RADIUS client resource.

In this example, we show the OTP authentication method (users append the OTP for their token to their password).

  1. Install the two certificates exported from Palo Alto on your computer.
  2. Start the GlobalProtect client.
  3. Type the IP address of your Palo Alto ethernet1/1 interface. Click Connect.

    Screen shot of the test

  4. In the Username text box, type your AuthPoint user name.
  5. In the Password text box, type your password and the OTP for your token (shown in the AuthPoint mobile app). Do not add a space between your password and your OTP.

    Screen shot of the test

  6. Click Sign In.
    You see the Sign In screen again.

    Screen shot of the test

  7. You must sign in a second time. Let your OTP refresh before you authenticate. You must use a different OTP the second time you log in.
  8. In the Password text box, type your password and the OTP for your token (shown in the AuthPoint mobile app). Do not add a space between your password and your OTP.

    If you authenticate with a push notification, you must approve another push notification when you authenticate the second time.

  9. Click Sign In.
    You are logged in successfully.
