title: Is there a way of checking what type of authentication a website is using?
body: <p>I'm trying to use python with suds to connect to a microsoft exchange server, but I can't authenticate and download the services.wsdl file. </p>
  
  <p>I have also tried just using urllib2 to try and connect, but that also fails.
  I can however authenticate and download the Outlook Web Access page.</p>
  
  <p>I've tried using ntlm auth, but that also gives me a 401 error. Is there are way of checking what type of authenication I need, so I can check if I was using the type of auth in the first place.</p>
  
  <p>Thanks</p>
