I suppose you have added httpd parameters through db keys and not directly in httpd.conf file, right?
I use the following commands for tunning my ibays as hosting for dinamic web content:
db accounts setprop test FollowSymLinks enabled
db accounts setprop test AllowOverride all
db accounts setprop test PHPBaseDir /home/e-smith/files/ibays/test:/tmp
signal-event ibay-modify test
But that is not what the OP asked and only works for PHP applications, OP does not state clearly he is using a PHP application.
The files folder he wants to share is normally not exposed by the webserver and protected to not be accessible from the webbrowser. It is this protection the OP is finding on his path.
ltwally why do you need to expose the files location, can you not put the contents in a (sub)folder of the html folder? This folder is exposed to the web by default and your content of files should be available without further hassle.
If you really want to expose the files location to the web you will need to create a custom-template fragment. The permissions are defined in the following file: 90e-smithAccess40ibays, you need to create the same directory structure in the templates-custom tree and copy the file in there and make modifications to this copy. More information on the template system can be found in the SME Server Developers Guide which can be found in the wiki.
Be carefull, the file defines the properties for every files folder in all available ibays, so you might be better of relocating the files folder.
