Hi,
We encounter a problem with web AUthentication fallback in a catalyst 3750.
We configured 802.1x on the 3750. This works great but the pb is with the fallback Webauth. When the client has no proxy configured there is no pb; I mean the client is prompted with the authentication webpage. But if the client has a proxy he doesn't. The client can browse internet throught the proxy but the switch port remain in the INIT state of ip admission and is never prompted:
Authentication Proxy Cache
Total Sessions: 1 Init Sessions: 1
Client IP 10.166.194.54 Port 0, timeout 1, state INIT
So he can't do anything else that browsing internet...
Any idea about how to access the authentication webpage if there is a proxy configured in the browser ?
Thanks for your answer

It seems that local authentication for auth-proxy is not supported (not 100% sure. Please provide IOS ver and aaa config for the switch in question.

at least on my 1721 local proxy auth does work, however, I cannot figure out how to configure any more granular control then simple pass/fail
