curl supports numerous different HTTP authentication methods and you can do
plain HTTP post logins with it. It really doesn't matter what kind of system
that is behind the site as long as it uses one of the supported methods.

That indicates something in your request isn't like it would be when a browser
does the request: cookies, user-agent, referer or more. Work on making your
request more similar to that of a browser doing the same thing.
