Apache help wanted

[Tim Wunder]

Hi, 
In migrating from Apache 1 that was included with Caldera eW3.x to Apache 2 provided by Red Hat 8 (version 2.0.40), I've gotten pretty much everything to work OK. Except for the following:

- I can't seem to get Apache to to load one of the files listed by the DirectoryIndex line for a directory other than the directory root (and users' public_html directories). I'm apparently missing something obvious, but it's eluding me... 
For example, I've got a web-based calendar on my webserver (Webcal), and have an aliased directory /calendar that calls up the /cgi-bin/webcal directory and I have the following entries in my httpd.conf file:

DirectoryIndex index.html webcal.cgi index.html.var index.cgi main.htm

But when I try to access <URL>/calendar, I get an access denied error. If I add webcal.cgi at the end, it loads. Permissions on the calendar directory are 755
I've asked on IRC (#apache) and the guy/gal there couldn't figer out why it wouldn't work. Anybody wanna make a suggestion? I'm stumped :-(

httpd.conf file available upon request...

Thanks, 
Tim
