You should have a acs directory tree in the web home directory.
copy the acs tree to /webroot/{service_name} for every ACS server run on this system
Example: To set up two acs comunities: www.arfdigita.org and dev.arfdigita.org we need two seperate acs dirs under /webroot. The dir names, {service_name}, used under webroot are simply names to distinquish services from eachother
