title: Access denied (error 403) to Tomcat 8 Manager on CentOS 7 without prompting for login/password
body: <p>I have set-up a CentOS 7 VPS with Tomcat 8 to serve my applications to my institute, following <a href="https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-8-on-centos-7" rel="nofollow">this guide</a>. I can access the Tomcat server usual page but not the App Manager. I believe I well configured the <code>tomcat-users.xml</code>, but I have no prompt for a login and password and it keeps telling me "403 Access denied". 
  I already configured tomcat 8 but on an Ubuntu Server more than one year ago, and it worked out of the box.
  There is probably something I missed .... but I can't see what it is. </p>
  
  <p>Here is a copy of my <code>tomcat-users.xml</code> : </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;tomcat-users xmlns="http://tomcat.apache.org/xml"
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
                version="1.0"&gt;
      &lt;role rolename="manager-gui"/&gt;
      &lt;user username="tomcat-xxxxxxx" password="xxxxxxxxxxxxxxx" roles="manager-gui"/&gt;
  &lt;/tomcat-users&gt;
  </code></pre>
  
  <p>Thanks for your help !</p>
