Getting "Access Denied" through proxy from an external Windows web page

I am a newbie to Linux who was asked to setup a proxy server. I seem to have everything in working order except for a external webpage that requires authentication. I can access the login credential page without the proxy being setup. If I input an incorrect user/password on this page I receive the same error page as I do when using the proxy. I have looked through previous questions and someone did have this problem and was refered to an NTLM authentication article (http://www.squid-cache.org/Doc/FAQ/FAQ.html) that I do not see as having any relation to this issue. As I am very new to Linux and proxys I would appreciate a fairly dumbed up answer :)

Thanks

Basically because you are going though a proxy it causes a problem with kerberos (or at least the ntlm login) trust so when authenticating against a site that uses trust it fails. The alternative is to either go via ssl logon or use plaintext password. Not really much help I know but the only way I got around it wa to disable the proxy when logging into these sites.

Thanks for the comments. Since I am unable to make changes to the webserver we are trying to access and the clients using the proxy are locked down and unable to turn off access to the proxy is there a 3rd party solution to this. This can't be a new issue?
