title: SonarQube 6.7 using Sonar Auth Github 1.3 Plugin
body: <p>I am trying to use SonarQube with Github as authentication. </p>
  
  <ul>
  <li>Here it shows the plugin is <a href="https://docs.sonarqube.org/display/PLUG/Plugin+Version+Matrix" rel="nofollow noreferrer">compatible</a></li>
  <li>I've followed the <a href="https://docs.sonarqube.org/display/PLUG/GitHub+Authentication+Plugin" rel="nofollow noreferrer">instructions</a> to setup the plugin</li>
  </ul>
  
  <p>When I try to authenticate I get this error in the log</p>
  
  <blockquote>
    <p>[o.s.s.a.AuthenticationError] No provider key found in URI</p>
  </blockquote>
  
  <p>Then I am redirected to </p>
  
  <blockquote>
    <p>"GET /sessions/unauthorized HTTP/1.0" 200</p>
  </blockquote>
  
  <p>I found in the SonarQube <a href="https://github.com/SonarSource/sonarqube/blob/master/server/sonar-server/src/main/java/org/sonar/server/authentication/AuthenticationFilter.java#L52" rel="nofollow noreferrer">code</a> where the error is thrown.</p>
  
  <p>This is the source for the <a href="https://github.com/SonarSource/sonar-auth-github" rel="nofollow noreferrer">Github Sonar Auth Extension</a></p>
  
  <p>How does one place a provider key in the URI? </p>
