Hello, I'm using squid as a cache server working with webwasher (proxy + authentication + webpage filter). Here's the context : User's computer<---->Squid <----> Webwasher<--->Internet | | Authentication |(Using NTLM) | NTLM Agent When a user is connect directly on webwasher it works. He is authenticated worretly (I can see that thanks to logs). But once I implement a Squid cache server, it doesn't work. My user can't be authenticated. Does anyone has an idea? I'm using squid 2.6 running on a RedHat linux server 5. Right now i'm trying squid 3 but it dosen't seem to work too. I will send a message later to talk about my progress.
