title: Apache: “AuthType not set!” 500 Error
body: <p>It's been a while since I used the Apache httpd web server in windows.
  when I try to request localhost/index.html, I get a 500 error and I see this in the error log:</p>
  
  <blockquote>
    <p>[client 127.0.0.1] configuration error:  couldn't perform authentication. AuthType not set!: /</p>
  </blockquote>
  
  <p>This line in my httpd.conf may be involved.</p>
  
  <pre><code> &lt;Directory /&gt;
      Options FollowSymLinks
      AllowOverride All
      Require all granted
   &lt;/Directory&gt;
  </code></pre>
  
  <p>my apache version is 2.2
  <br>OS : windows 7
  how do I solve this 500 error?</p>
