I have an account 'user' that I want to be able to ftp into the server and upload pages into the root of the server '/var/www/html' (as listed as "ServerRoot" in my httpd.conf in apache). However, when 'user' ftps in, and tries to upload into the directory, he gets a permission denied error. How do I create an ftp user that has permission to upload into the 'ServerRoot'?
