Abstract
Users on a client system access files served by a web application through the Network File System (NFS) protocol using common web authentication mechanisms while still honoring constraints imposed by the application's authorization rules. To this end, the client system is modified to include an NFS server. Following authentication of the NFS server with the web application, NFS-based requests (from a local NFS client) directed to the application are received at the NFS server instead of being sent to the application directly. The NFS server, in turn, maps those requests to the web application preferably using standard HTTP. Because the web application's normal security model is enforced as intended at the web application, the approach enables individual users of the client system to operate under different visibility constraints dictated by the web application. Thus, fine-grained permissions may be enforced at the web application for different users.
