I like LDAP but most would probably consider this overkill for a home
network.

Apple starts numbering uid's at 500 (first user) and increments each new
user from there. Ubuntu starts numbering users at 1000.

The following link explains how you can change the uid #'s on the Macs
to conform - this solved my particular problem on a network where some
Macintosh users saving files on a Windows server would cause issues but
the same principal applies. There are instructions for both Tiger and
Leopard.
