Array Networks SSL VPN Integration with AuthPoint

Deployment Overview

This document describes how to set up multi-factor authentication (MFA) for Array Networks Server and SSL VPN client with AuthPoint. Array must already be configured and deployed before you set up MFA with AuthPoint.

This integration was tested with Array Networks Server version AG.9.4.0.5 and Array SSL VPN client for Windows version 9.0.1.115.

Array Authentication Data Flow with AuthPoint

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.

Before You Begin

Before you begin these procedures, make sure that:

  • End-users can log in to the Array
  • A token is assigned to a user in AuthPoint
  • You have downloaded and installed the AuthPoint Gateway (see About Gateways)

Array Radius Configuration

Array can authenticate users via several methods. In this document, the RADIUS based authentication is used.

Configure AuthPoint

Before AuthPoint can receive authentication requests from Array, you must specify Array as a RADIUS client resource in AuthPoint. You must also assign an access policy for the Array resource to the user group(s) that must authenticate and you must bind the Array resource to the AuthPoint Gateway.

Add a Array 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 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 Array interface IP address which connect to AuthPoint Gateway.
  3. From 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 same as Array.
  5. Keep Enable MS-CHAPv2 disable.
  6. Click SAVE.

Add an Access Policy to AuthPoint

You must have at least one user group in AuthPoint for authentication with Array, and you must assign an access policy for the Array 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.

Before you assign users to a group, you must add the users to AuthPoint. You can manually add user accounts or import user accounts from an external user database. For more information on how to add user accounts, see Add User Accounts.

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. For more information, see About Gateways.

  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.

Test the Integration

To test AuthPoint MFA with the Array SSL VPN client, you can authenticate with a mobile token on your mobile device. For RADIUS resources, you can choose one-time password (OTP) or push.

In this example, we show the one-time password authentication method.

  1. Open the Array SSL VPN client.
  2. Select Profile > Create.
  3. Type a Profile Name.
  4. In the VPN Server text box, type the IP address you specified for the virtual site in Step 6 of the Create an SSL VPN Virtual Site section.
  5. In the VPN Port text box, type 443.
  6. Click OK.
