If I'm clear on this, you want to type in
http://www.bentonbsa.org and be redirected to ibay folder mrlistersir/baloo.
If so then you are trying to redirect to a folder in an ibay not just the ibay. You will need some code to do that. You can modify the Apache config I think or possibly do something in an .htconfig but I'm not sure of the procedures.
An easy solution is to make the index page an index.php page in ibay bentonbsa that contains just:
echo "<script>self.location = '
http://www.mrlistersir/baloo';</script>";
This will have the possibly unfortunately effect of changing the url displayed in the browser.
