Running Hiper ARC 5.3.3. Just tried to verify a user using the _AUTH USERNAME PASSWORD command from telnet to the ARC and can't do it. Same user CAN authenticate just fine when dialing up. I'm using Win2K/IAS for RADIUS. Event Log shows "Access Request ... discarded". Only info from M$ I could find says that if the client doesn't use a shared secret the request is discarded and ignored. Sounds like maybe my Hiper ARC isn't sending the secret when I do it from a telnet prompt?! Anyone else have this happen? I've monitored the RADIUS - and the ARC is sending requests to both RADIUS servers like it should - 3 requests to RADIUS1, then 3 to RADIUS2, then back to RADIUS1, etc. until it hits the retry limit and fails. No replies ever come back from the RADIUS server. I rebooted my main Radius box, didn't help - didn't expect it to because the problem is occurring when authenticating against both servers. And both servers still authenticating perfectly with dial-up users. Any ideas? Joel
