AFS is a distributed global file system that operates in the client-server
model. AFS is based on a distributed file system originally developed at the
Information Technology Center at Carnegie-Mellon University. It was called
the "Andrew File System." It can effectively function in large wide area
networks that span the entire globe as well as in small local area networks.
This document will explain how to install and configure AFS with
Kerberos security on your Windows
workstation. It assume you have already
installed Kerberos for Windows (KfW).

Adapter are checked.
