title: Reset admin password for Kibana
body: <p>I'm locked out of the admin page for our Kibana instance. I have a root shell on the box and can access all configurations. How do I go about resetting the admin password, so I can login to Kibana as admin? I can authenticate as kibana user, but I get this message when I try to manager users, "You do not have permission to manage users"</p>
