encryption of AFS file service traffic?

[RL Bob Morgan]

I seem to recall some discussion long ago on info-afs regarding encryption
of file service traffic between AFS client and AFS server.  As I recall it
was said at the time that this capability was present in standard AFS
clients and servers, but that the setting to turn it on in the client was
not documented and presumably not supported.  Can anyone confirm or deny
whether in fact this capability exists?  I believe that our site would
find it useful for this to be a standard supported feature.

Thanks,
