title: Why doesn't cURL work with Windows Authentication on IIS7?
body: <p>I am trying to access a service that is behind Windows Authentication. I thought I could pass the credentials the way HTTP Basic Authentication credentials are passed, but it's not working. When I do the following, I get a 401 error, and I am absolutely sure the password is correct.</p>
  
  <pre><code>curl --user username:password http://example.com
  </code></pre>
  
  <p>Why doesn't this work?</p>
