Perhaps you have seen my posts on the main Centos list, as I thought I 
had a HTTPD setup problem.  It may be a SELinux problem.

Basically all I am trying to do is set up a personal web server. Just 
some simple servername and admin settings and turning on user_dir.  I 
can access files in the directories, but not produce a directory 
listing.  Here is the access_log, error_log, and audit_log messages:

I suspect that there is a problem here with SELinux.
