title: Tomcat manager never asking me ID/PASSWORD
body: <p>I set up Apache Tomcat/9.0.0.M4 on Amazon Linux EC2 Instance.
  I completed to edit conf/tomcat-users.xml like this.</p>
  
  <pre><code>&lt;role rolename="manager-gui"/&gt;
  &lt;role rolename="manager-status"/&gt;
  &lt;role rolename="admin"/&gt;
  &lt;user username="tomcat" password="tomcat" roles="manager-gui,manager-status"/&gt;
  </code></pre>
  
  <p>and then, I restarted Tomcat with ./shutdown.sh and ./startup.sh
  I tried to log-in, but Tomcat web page never ask ID/Password of manager.
  It only show me this 403 error page like this.</p>
