proxy incoming PAP request as outgoing PEAP/TTLS requests

Hi Alan,

This is exactly we would like to do.
captive portal ------PAP-----> freeradius server ----PEAP/TTLS------> another radius server

As you said, it is a dangerous thing to accept PAP and it is not enabled on NPS by default.
Hence, we would like to proxy the PAP requests as PEAP/TTLS requests.
It is better that we could authenticate with the upstream server in the tunnel.

Thanks a lot.

another use case that *I* could think of its another attempted MITM attack against eg 802.1X in particular I am closely connected to. Present a captive portal....
get people to login using user/pass - the upstream servers are configured to reject non EAP methods so you dont know if such things are true details.... but if you converted that PAP request to an EPA method......
