title: How to disable root login on Virtualmin
body: <p>I’m using a vanilla Webmin / Virtualmin 3.93 GPL version on Centos 6. I’ve created a new user that has full privileges on Webmin, so now I want to disallow root from logging in, as obviously it could be a security issue.</p>
  
  <p>Does anyone know how to do this? There must be an option for this somewhere but maybe I can’t see the wood for the trees.</p>
  
  <p>I’ve disabled root SSH login manually, but I still can login to Webmin using the root account.</p>
