title: Linkedin "Scope" Variable not set
body: <p>I'm having trouble setting up a connection to Linkedin Api using Spring Social.</p>
  
  <p>I am passing the "scope" variable "r_emailaddress" as a hidden field with the form to retrieve the email address but it's not working - I don't see the email_address permission like you do here. <a href="https://developer.linkedin.com/sites/default/files/gp-dialog.png" rel="nofollow">https://developer.linkedin.com/sites/default/files/gp-dialog.png</a></p>
  
  <p>I am following the Spring Social Showcase Application Example.  I should add, the Social Application there is no hidden scope field.  </p>
  
  <p>It works fine with Facebook.</p>
  
  <p>Form</p>
  
  <pre><code>&lt;form name="linkedinin_signin" id="linkedin_signin" action="${linkedin_uri}" method="POST"&gt;
      &lt;input type="hidden" name="scope" value="r_basicprofile, r_emailaddress" /&gt;
      &lt;input type="image" src="${linkedin_img_uri}" /&gt;
  &lt;/form&gt;
  </code></pre>
