title: Newman(Postman) - Import collection from a URL under windows authentication
body: <p>I'm trying to run newman with postman collection from a url as mentioned in this <a href="https://www.getpostman.com/docs/v6/postman/collection_runs/command_line_integration_with_newman" rel="nofollow noreferrer">link </a>. </p>
  
  <pre><code>newman run http://localhost:62254/api/postman
  </code></pre>
  
  <p>Only catch is that the url is under windows authentication, so I'm getting a 401 Unauthorized response, causing newman to fail with below error.</p>
  
  <pre><code>the url "http://localhost:62254/api/postman" did not provide valid JSON data
  </code></pre>
  
  <p>I tried passing the credentials with the request like below. But it didn't work.</p>
  
  <p><a href="http://username:password@localhost:62254/api/postman" rel="nofollow noreferrer">http://username:password@localhost:62254/api/postman</a></p>
  
  <p>If I directly hit the endpoint with Postman using 'NTLM Authentication' feature it works fine. But I'm not sure if I can use this with newman to get the collection itself.</p>
