Accessing User Sites folder via Webserver

I am running 10.5.6 Server with Web services working, in a multi server AD / OD environment. The web server is bound to both AD & OD. I have a working url of http://www.server.tld I am able to access http://www.server.tld/~localadminaccount and any other account that I create in the local database and has a home folder in /Users on the local machine. This particular server is also running as a afp file server with automount setup for home folder use on a seperate volume of /Volumes/data/ with several sub-folders such as instructors, students, etc. When trying to access a student site for example http://www.server.tld/~18student, I am receiving a 404 error. I know that everything is working properly because http://www.server.tld resolves to the main OS X server page without error and http://www.server.tld/~localadminaccount resolves to the personal web sharing index.html file without error. My question is, it appears to either be a pathing issue or a problem with the user accounts not being on the local system volume. Would anyone be able to assist me in finding a solution to this. I want to be able to use the personal web sharing capabilities that appear to work if the user is local with a home folder in /Users on the system partition. However my users are spread into a significant folder structure on a seperate volume. For example: Our students are all located on this particular server in /Volumes/data/students// It is frustrating me as I know it can't be this difficult, and I am just missing something somewhere...obviously! Thanks!
