As far as I can tell, there is no information available on how to set up and configure things like IIS, FTP etc. (web hosting) in SolidCP.
Is there any such information available or is there anyone who can provide the necessary information on how to set this up?

I can without problems add servers/virtual servers for IIS/FTP, but without knowing how this should be configured on the servers, it doesn’t really work in a way I’m comfortable with.
For instance, the permissions set on web site directories allows everyone to access the directories and data, this should probably be segregated, like by using unique user accounts for App Pools and NTFS permissions for the web sites, perhaps this is already possible if the root directory structure is configured with the correct permissions for SolidCP (but what are they?).
