Hi, I'm using ntlm and winbind on rh enterprise 4.2 and i dont have any problem with authenticating users from AD (Its seamless operation when they are logged on domain). But im having problems when i deny with proxy_auth username directive. Because, squid is re-sending authentication request to client when he/she is not authorised to connect somewhere limited, and a pop up window appears asking for username/password. I want only domain logon information to be used, rather than user approved credentials. Is there any way to do this? I know its unusual, but i have a couple of users which not sensitive about their account information. So i have to limit them authenticated only by domain logon information. Thanks for any kind of help, -- M.Sinan BEYRIBEY
