Here are a couple more ways to affect "Indexes" that might work for you:
1. Create an "index.html" file in your i-bay that displays a blank page, an error message, or redirects the visitor to another site - then the autoindex function will never be invoked.
or
2. Create a custom template fragment that turns off indexing for the i-bay in question (note: the name I've given here is arbitrary, but must begin with a number high enough to cause 'expand-template' to add your content at the end of httpd.conf, so that your "Options -Indexes" will not be overruled by another setting later in the file)
# pico /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf/96TurnOffIbayIndexing
then add this content:
<Directory /home/e-smith/files/ibays/[ibayname]/html/ >
Options -Indexes
</Directory>
(be sure to replace [ibayname] with the name of your i-bay).
Then:
sbin/e-smith/expand-template /ect/httpd/conf/httpd.conf
/etc/rc7.d/S86httpd-e-smith restart
