As of LoadMaster firmware version 7.2.52, RADIUS two-factor and LDAP authentication is supported. To configure this, follow the steps below in the LoadMaster WUI:

  1. Select RADIUS and LDAP as the Authentication Protocol when adding or modifying a client-side Single Sign On (SSO) domain in Virtual Services > Manage SSO. If the RADIUS server is configured to use two-factor authentication, the LoadMaster will detect this automatically and perform RADIUS two-factor authentication.
  2. Set the LDAP Endpoint and RADIUS Server(s) for this SSO domain.
  3. Select Exchange or Blank as the SSO Image Set in the ESP Options section of the Virtual Service Modify screen.
  4. Set the other parameters as appropriate for your configuration.
