Okta Authentication with Okta API Token

Overview

Aviatrix User VPN Gateway supports Okta authentication as part of multi-factor authentication for OpenVPN® access.

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. Setup Okta authentication
  3. Create VPN Users for this Aviatrix Gateway
  4. Test connectivity

Important

Okta authentication can be enabled both at the Aviatrix gateway launch time and after the Aviatrix gateway is launched. We highly recommend you configure Okta after the gateway is launched.

Obtain 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 the Create Token button. Give the token a name (for example, Aviatrix).

    Note

    Copy the generated token value. You’ll need this token to allow the Aviatrix Gateway to access Okta.

  3. Enter details about your Okta environment:

    Field Description
    URL Your Okta account login URL. (For example, https://aviatrixtest.okta.com)
    Token The token value you copied earlier
    Username Suffix

    If provided, the VPN username will be the account ID without the domain name.

    For example, if your Okta account is demoaviatrix@aviatrixtest.com and aviatrixtest.com is your Username Suffix, the VPN username should be demoaviatrix.

    If no value is provided for this field, you must enter the full username including domain name (for example, demoaviatrix@aviatrixtest.com).

    Important

    This username must match the username in Okta.

  7. (Optional) Enter the user’s email where the .ovpn file will be emailed.

    Note

    If an email is not provided, users will need to download their .ovpn file from the Controller.

    AddVPNUser

Validate

  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 login

    Note

    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.
