+   <h1>401 Unauthorized</h1>
+   <p>
+    You are not authorized to view this page. If you have not changed
+    any configuration files, please examine the file
+    <tt>conf/tomcat-users.xml</tt> in your installation. That
+    file must contain the credentials to let you use this webapp.
+   </p>
+   <p>
+    For example, to add the <tt>admin-gui</tt> role to a user named
+    <tt>tomcat</tt> with a password of <tt>s3cret</tt>, add the following to the
+    config file listed above.
+   </p>
+<pre>
+<role rolename="admin-gui"/>
+<user username="tomcat" password="s3cret" roles="admin-gui"/>
+</pre>
+   <p>
+    Note that for Tomcat 6.0.30 onwards, the roles required to use the host
+    manager application were changed from the single <tt>admin</tt> role to the
+    following two roles. You will need to assign the role(s) required for
+    the functionality you wish to access.
+   </p>
+    <ul>
+      <li><tt>admin-gui</tt> - allows access to the HTML GUI</li>
+      <li><tt>admin-script</tt> - allows access to the text interface</li>
+    </ul>
+   <p>
+    The HTML interface is protected against CSRF but the text interface is not.
+    To maintain the CSRF protection:
+   </p>
+   <ul>
+    <li>The deprecated <tt>admin</tt> role should not be assigned to any
+        user.</li>
+    <li>Users with the <tt>admin-gui</tt> role should not be granted the
+       <tt>admin-script</tt> role.</li>
+    <li>If the text interface is accessed through a browser (e.g. for testing
+        since this interface is intended for tools not humans) then the browser
+        must be closed afterwards to terminate the session.</li>
+   </ul>
+ </body>
