Best way to serve home directories?

[Paul Waldo <pwaldo sysnet net>]

Hi all,

I have a RH 5.2 box that, among other things, is to serve up home
directories for other Linux and 'doze boxes.  I thought at first using
NIS was the way to go, but learned that it is insecure.  Since
eventually I want to be connected to the Internet all the time, I gave
up on that idea.  BTW, I have a gateway machine running ipfwadm.  So
next I tried just doing an NFS export of home directories, but due to
UID conflicts between the different Linux machines, that didn't work. 
Any ideas on what to try next?  TIA.

Paul
