Okta SAML Authentication with WatchGuard Access Portal Integration Guide

Deployment Overview

You can configure Single Sign-On to use SAML authentication and enable your users to log in through one portal and get access to multiple services.

This document describes how to set up SAML authentication through the WatchGuard Access Portal with Okta as the Identity Provider.

Test Topology

This integration uses Okta Identity Cloud services to communicate with a WatchGuard Firebox over a public Internet connection.

Configure Your Firebox for Okta

The WatchGuard Access Portal is a subscription service. Before you can configure Access Portal on your Firebox, you must have an active Total Security Suite license in your Firebox feature key.

To configure the Access Portal settings on your Firebox for Okta:

1. Log in to Fireware Web UI.
2. Select Subscription Services > Access Portal.
3. Select the Enable Access Portal check box.

4. Select the SAML tab.
   The SAML tab appears.
   
5. Select the Enable SAML check box.
6. In the Service Provider (SP) Settings section, type the IdP Name and Host Name.
   You add the IdP settings later in this process.
   • IdP Name — Specify a name for the SAML authentication to appear in other Firebox settings as the server name.
   • Host Name — Specify the fully qualified domain name that resolves to the Firebox external interface.

7. Click Save.
8. Go to https://<host name>/auth/saml.
9. Make sure you have this information from the /auth/saml page:
   • SAML Entity ID in this format: https://<host name>/auth/saml
   • Assertion Consumer Service (ACS) URL in this format: https://<host name>/auth/saml/acs
   • Single Logout Service (SLS) URL in this format: https://<host name>/auth/saml/sls
10. Download the certificate.

Configure Okta

Add an Okta Group and User

After you have completed these configuration steps, users in the group you added can sign in to either the Okta account or to a resource configured with Okta SAML Single Sign-On.

   The login page opens with the name of the SAML portal you configured previously.

2. To log in, click the name of the SAML portal. In this example, click My_Okta.
   
3. Complete the authentication process in Okta.
   After successful authentication, the user can get access to the resource.
