The config file shipped with SWS 3.0 has an error that is a possible security flaw. The apache group changed the globbing in the 1.3.x to be more shell compatiable than in the previous versions so /*/public_html will no longer work. With this typo in order to add user level cgi access you must turn it on globally which causes serious security problems with the webserver. The proper format should be /home/*/public_html or ~/*/public_html (The latter does not seem to work all the time).
wil - we corrected this for SWS 3.1 but I don't consider it enough of a security hole to issue errata for 3.0, as we are encouraging everyone to get a free upgrade to 3.1 anyway.
