I was mistaken about him running Linux. It turns out he's on Mac OS X Snow Leopard, using Claudio Bisegni's AFS Commander as a GUI interface. He's added as a side problem that kerberos tickets do not seem to autorenew like he needs for long-running jobs. He does not know what version of the AFS client he's running, though it was one from the last few months. Thanks again.
