ISPConfig

Hi,

does anyone have any experience installing airtime (or campcaster) on an ISPConfig server.
I'm installed both. Somehow airtime seems to break up the ISPConfig setup.
It's Debian 6 (squeeze), ISPConfig 3.0.3.2 and then airtime 1.6.0.

One of the issues is that squirrelmail (http://ip/webmail) defaults back to airtime.

I would like to have airtime run in a subdomain (http://airtime.domain.tld).
Any suggestions are welcome.

Thanks.
Ed
