[squid-users] Reverse Proxy for Exchange server

[Hannes Fasching]

Hi!
I have an issue with the accel mode in front of an exchange server. When you configure more than one authentication scheme including the basic scheme the authentication does not work - connection will be closed.
But when you configure the basic scheme only is starts working.
When you have configured more authentication schemes it looks like the exchange autodiscover tries which authentication scheme is the right one - gets back the HTTP Status 200 for basic scheme and for all others 401 and the last connection/session is not for basic scheme so it gets answered with 401 and squid is closing the server side and after detecting a "half closed" connection squid is also closing the client side.
Also the "cache_peer" parameter "connection-auth=on" changes nothing.

Thanks in advance for your answer
