A RADIUS client needs to be created so that the LoadMaster can authenticate. Create a RADIUS client by following the steps below:

  1. Open the Server Manager application.

  2. Navigate to the following option: Roles > Network Policy and Access Services > NPS (Local) > RADIUS Clients and Servers > RADIUS Clients.

  3. Click New in the panel on the right.

  4. Enter a Friendly name.
  5. Enter the IP Address of the LoadMaster.
    Note: If using a High Availability (HA) pair, add all three IP addresses (unit 1, unit 2 and the shared IP address).
  6. Enter a Shared secret.
    Note: The Shared secret has a 48-character limit.
  7. Enter the same shared secret in the Confirm shared secret text box and click OK.
  8. When the LoadMaster contacts the RADIUS server, it uses the active physical interface. Therefore, two RADIUS clients must also be configured in addition to the shared address. Follow the steps above (using a different IP address) to create the additional RADIUS clients.
