There are two methods to authenticate a VPN user against Okta: using an Okta API Token or using the Aviatrix VPN SAML Client. This document shows you how to set up authentication using the Okta API Token. Okta API Token is a method where the Aviatrix VPN Gateway authenticates against Okta on behalf of VPN clients using the standard Okta API. When this method is used, you can continue to use a native OpenVPN® client such as Tunnelblick while using MFA authentication. Follow these steps to configure Okta authentication and MFA on a User VPN Gateway in your environment:
  1. Obtain an API token from your Okta account.
  2. Set up Okta authentication.
  3. Create VPN Users for this Aviatrix Gateway.
  4. Test connectivity.
Okta authentication can be enabled either at the Aviatrix Gateway launch time or after the Aviatrix Gateway is launched. We highly recommend you configure Okta after the gateway is launched.

​
Obtaining the API Token from Okta

Follow the steps outlined in the Okta documentation to create a new API token.
  1. Log in into your Okta account as a Super Admin. This allows the privilege to create a Token for API access.
  2. Go to Security > API and click Create Token. Give the token a name (for example, Aviatrix).
    Copy the generated token value. You’ll need this token to allow the Aviatrix Gateway to access Okta.

Setting up Okta Authentication

  1. See this guide to create a new Aviatrix VPN Gateway.
  2. When you are ready to configure Okta, go to Aviatrix CoPilot > Cloud Fabric > UserVPN > select the UserVPN Gateways tab.
  3. Find the gateway and click the Edit icon.
  4. Find the Authentication setting, click on the dropdown option, and select Okta.
  5. Enter details about your Okta environment:
Okta Setup
  1. Click Save.

​
Creating User(s)

Create a UserVPN user.
This username must match the username in Okta.
  1. (Optional) Enter the user’s email where the .ovpn file will be emailed.
    If an email is not provided, users will need to download their .ovpn file from the Controller.
  2. (Optional) Select a profile for this user.
  3. Click OK.

​
Validating

  1. Use the .ovpn file emailed to your test account or download it from Aviatrix VPN Users.
  2. Add the configuration to your VPN client.
  3. Connect and log in.
    Since Aviatrix Okta authentication uses API authentication, it uses the default sign on policy of Okta. If you have configured Multi-factor Authentication in Okta, then during VPN login, the end user needs to append his MFA token to the password during authentication.
