Hi We use the TMG to publish OWA with Radius onetime passcode, and it works perfectly. Now we also want to use TMG as our VPN server whit Radius onetime passcode, but it won't work. To start we setup PPTP with windows authentication and it work, then we switch to use Radius,(the same Radius server as with the OWA) authentication is set to PAP,I can see on the Radius server that the passcode is accepted, and with netmon. i can see the reply back is ok, but the connection failed. Can the TMG not use Radius ontime passcode for VPN?
I run PAP as the Radius only accept clear password, the trouble is possible that TMG radius is sending the passcode 3 time to the radius, can't see why. Our OWA is also running with the radius ontime passcode, and it works. Also try from XP client the same result, as soon I switch for no radius there is connection with PAP MS-Chap and V2. It can be a bug in TMG Radius, I am stuck.
