Hi, I'm trying to set Apache as proxy server to an internal SharePoint server. I have previously configured Apache to run as a proxy server to export internal webpages and web applications. However, the Sharepoint is using SSL and NTLM authentication, and this is new to me :( I have tried many options, the traffic seems to be forwared as I get the authentication popup window, but when I insert the user/pass, I get back to the same popup window. Anybody has configured Apache to do so? Here is a part of my httpd.conf: <VirtualHost *:443> ServerName repository.out.com SSLProxyEngine On RequestHeader set Front-End-Https "On" ProxyRequests Off ProxyPreserveHost On ProxyPass / https://sharepoint.in.com ProxyPassReverse / https://sharepoint.in.com CacheDisable * SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 ErrorLog logs/jlanza_log CustomLog logs/jlanza_log common </VirtualHost>
