hi, i have a mac mini server with latest mountain lion os. i would like to make a simple to use webdav fileserver for clients that is secure. i wonder if there are any experts in file sharing, security, mac os and the apache webserver who could help? the first thing i would like to know how to do is to create new users from a web interface. apple have already created a way to let users change their password via a web interface. i wonder if anyone knows how this works, is it via php, cgi or ruby (or something else?) and if so, how could i write my own web-app that allows admin users to log in and create users. thanks, james.
