title: saml-php error code explanation
body: <p>I am very new to the SAML arena, and I am trying to implement this into my app as an SP only, using saml-php from OneLogIn.  As it now stands, I am able to get it working using a OneLogIn test app, however, whenever an outside source attempts to log in through it, I get the following error:</p>
  
  <pre><code> Fatal error: Uncaught exception 'OneLogin_Saml2_Error' with message 'SAML Response not found, Only supported HTTP_POST Binding' in 
  </code></pre>
  
  <p>followed by a stack trace through my various files.  Since I do not have much experience with all of this, could someone explain what this means?  Where do I need to start looking in order to debug it.</p>
  
  <p>Please, if any additional information would be helpful, let me know, and I will provide it. </p>
  
  <p>Thank you in advance!</p>
