title: Getting 403 access denied error when uploading war file to tomcat8
body: <p>I can login and access the manager page, but when I try to upload a war file it fails with a 403 error.  I have already added permissions in tomcat-users.xml  Here is the relevant line:</p>
  
  <pre><code>&lt;user username="admin" password="password123" roles="admin,manager-gui,admin-gui"/&gt;
  </code></pre>
  
  <p>The Valve class in /usr/share/tomcat8-admin/manager/META-INF/context.xml is already commented out.</p>
  
  <pre><code>&lt;Context antiResourceLocking="false" privileged="true" &gt;
    &lt;!--
      Remove the comment markers from around the Valve below to limit access to
      the host-manager application to clients connecting from localhost
    --&gt;
    &lt;!--
    &lt;Valve className="org.apache.catalina.valves.RemoteAddrValve"
           allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /&gt;
    --&gt;
  &lt;/Context&gt;
  </code></pre>
  
  <p>When I try to upload a war file I still get the message:</p>
  
  <pre><code>403 Access Denied
  
  You are not authorized to view this page.
  
  If you have already configured the Manager application to allow access and you have used your browsers back button, used a saved book-mark or similar then you may have triggered the cross-site request forgery (CSRF) protection that has been enabled for the HTML interface of the Manager application. You will need to reset this protection by returning to the main Manager page. Once you return to this page, you will be able to continue using the Manager appliction's HTML interface normally. If you continue to see this access denied message, check that you have the necessary permissions to access this application.
  
  If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation. That file must contain the credentials to let you use this webapp.
  
  For example, to add the manager-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above.
  
  &lt;role rolename="manager-gui"/&gt; 
  &lt;user username="tomcat" password="s3cret" roles="manager-gui"/&gt;
  Note that for Tomcat 7 onwards, the roles required to use the manager application were changed from the single manager role to the following four roles. You will need to assign the role(s) required for the functionality you wish to access.
  
  manager-gui - allows access to the HTML GUI and the status pages
  manager-script - allows access to the text interface and the status pages
  manager-jmx - allows access to the JMX proxy and the status pages
  manager-status - allows access to the status pages only
  The HTML interface is protected against CSRF but the text and JMX interfaces are not. To maintain the CSRF protection:
  
  Users with the manager-gui role should not be granted either the manager-script or manager-jmx roles.
  If the text or jmx interfaces are accessed through a browser (e.g. for testing since these interfaces are intended for tools not humans) then the browser must be closed afterwards to terminate the session.
  For more information - please see the Manager App HOW-TO.
