Every other site I have either setup and or administer via a commercial hosting solution uses the same account for both the MYSQL and the FTP account. Wouldn't this be easier, surely there is a way to do this? Why does the MYSQL require yet another unix account?
You can do this in ISPConfig as well, but then you must run your server with SuPHP instead of mod_php. There are several thraeds about suphp configuration in the forum, if you want to try this.
