Granted, it's a small network with few nodes. Changing uids is
probably workable in this case, and may be the solution I end up going
with. But it doesn't seem like it scales very well. If I'm uid 1000,
how hard is it for any random person to create some uid 1000 on their
machine, connect to the network, and access my files with my
permissions? That seems pretty insecure to me.
Take a look at this for a similar issue :

I'd prefer to have some other mechanism for authorization. That's the
core of what I'm asking. I will poke at Kerberos a bit, and if I have
success setting it up, I will probably go with it. If it seems too
involved for my simple little network, then I'll get busy changing uids.

To me, the better question is 'you wouldn't believe anyone having ID #
1000 is guaranteed to be the same person, would you?'.
