Hi Alan, Thanks for your comment. Actually, the captive portal backend service and the freeradius server are on the same device. We would like to transfer the requests as PEAP/TTLS before the requests go out the device. Thanks a lot. -----Original Message----- From: Freeradius-Users [mailto:freeradius-users-bounces+ian.chang=zyxel.com.tw@lists.freeradius.org] On Behalf Of Alan DeKok Sent: Tuesday, September 22, 2015 9:02 AM To: FreeRadius users mailing list Subject: Re: proxy incoming PAP request as outgoing PEAP/TTLS requests On Sep 21, 2015, at 8:57 PM, Ian Chang-張志邦 <Ian.Chang@zyxel.com.tw> wrote:

OK....
As you said, it is a dangerous thing to accept PAP and it is not enabled on NPS by default.
That isn't true.
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.
No. That's not true, either. The whole point of EAP is that NO ONE outside of the end user, and home server know what the password is. The access point doesn't know it. The intermediate proxies don't know it. Since the captive portal already sees the PAP password, adding EAP is useless. It's *worse* than useless because it's adding complexity for no benefit. This is like saying "locks as good. But my house is old, and doesn't have a lock on the front door. So I'll put a lock on the floor beside my bed. That will help!" No, it won't help.
