Apache: “AuthType not set!” 500 Error
<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>
