FTP access to roundcube pkg install directories
I've installed roundcube using the pkg file from ispconfig.org/downloads.htm - which is excellent by the way.
I can't seem to ftp to this location in order to customize my roundcube installation (skins,logo, etc). I can of course telnet there using SU.
Is there a user created for this purpose? or will I have to create a linux user for this purpose and enable in proftp (and how)? or can I give permissions to an existing user? or do I use the admispconfig user (I'm unaware of the password)?
I realize I can install roundcube independently on each of my websites and be able to access each one easily using FTP, but I wanted to avoid this if possible and just be able to edit files via ftp in the base roundcube (pkg installation) directory.
