That documentation may need revising. In any case, Debian users ought to
take a look at /usr/share/doc/openafs-*/ for distribution-specific guidance.
I mentioned /usr/sbin/afs-newcell; you can either trust it blindly and run
it, or use it as documentation, read it and ponder.

And what are you going to have in CellServDB ? I believe you're asking
for trouble if the gethost*() and the CellServDB views of things don't
match. AFS is a network file system, so I'm pretty sure that 127.0.0.1
is not going to be a useful address for your server.

AFS authentication is Kerberos-based. (Originally Kerberos 4, but that's
obsolete. Might be OK for a closed cluster, though.) If you want No File
Security, you should be using NFS. It may well give you better performance,
too, although a lot depends on the size of the cluster and the I/O
patterns you'll be dealing with.

You can of course use IP-based ACLs (or even a horror like 
"system:anyuser rwlidka"), but you do need at least a keyfile and a few
PTS database entries. Anyway, you did ask where the kaserver was.

[I see I'll have to cc: the list on this one. Sometimes I avoid it,
since my posts to the list have to go through the moderator, which
results in unpredictable delays.]
