1.Regarding FortiAuthenticator's support for both Radius and Tacacs, as a Radius Server, it supports CHAP and PAP as multi-factor authentication methods for verification. I would like to know how FortiAuthenticator, as a Tacacs Server, performs multi-factor authentication with Tacacs Clients.
2.Based on the FortiAuthenticator specifications, both physical and virtual versions of FortiAuthenticator support a certain number of "NAS Devices." Does this "NAS Devices" include both Radius Clients and TACACS Clients?
Based on your response, does this mean that TACACS only supports Token Appended? From my understanding, token challenge is based on CHAP, but according to the documentation for FortiAuthenticator, it does not support CHAP. Is my understanding correct?
