1. WebADM/OpenOTP/Radius Bridge For this recipe, you will need to have WebADM/OpenOTP installed and configured. Please, refer to WebADM Installation Guide and WebADM Manual to do it. You have also to install our Radius Bridge product on your WebADM server(s). The WLAN protocol used does not support challenge-response, so only Login Mode LDAP or LDAPMFA is supported. You should create a client policy that defines the correct login mode for the WLAN authentication.
