You mean that when you fill them in with your browser it works?

Then, start trying to identify how the browser's POST differs from yours:

 1. Did you fill in user+password in the browser before the actual post? I.e
    do you get a 4XX error code in the HTTP headers back when you use curl?

 2. Your POST line doesn't include "btnSubmit=Login" which may or may not be
    relevant. (the HTML <form> tag includes it)

 3. Your browser uses a user-agent string that the remote server may use
    to detect "false" logins.

If the -L means that curl follows a location, it may imply that several
requests are performed and thus we can add:

 4. You might get cookies back that need to be sent on subsequent requests,
    enable curl's cookie engine with -b.

 5. You might need to set the referer string, try -e.

 6. There are probably more details I haven't thought of right now.

Welcome to give-me-your-best-guess hour!
