-Integrated Windows authentication does not work over HTTP Proxy connections.
-Additional TCP ports have to be opened in the firewall.
I went to the above web site and checked that the integrated Windows Authentication does not work over HTTP Proxy connection? Why is that the case? IF I am not wrong, the proxy only there to forward the request? I mean it would be perfectly make sense to me to open additional port if required but I didn't get the idea that the IWA didn't work in the HTTP proxy connection.
any thought around this?
