I am trying to use Ajaxterm and I remember that when I used it for the first time about a year ago, there was something about logging in as root. 
Can anyone tell me how to enable root login or point me to a guide? Many different google searches have returned no results. 
P.S. My question is NOT whether or not I should login as root, but how to login as root.
Once you have logged in as a non-root user you can just su to the root user
