DHCP will give a random or semi-random IP address within that range, and LDM
will use an account based on the IP address given.

It's a script to be run from the server. adjust the "seq" line for your ip
address ranges, or anything else appropriate to your configuration. It assumes
each user has their own group with the same groupname as the username. I also
use a slightly more complicated setup which restricts which IP address each
login can come from, since it's a shared ssh key.

They don't, in fact, we wipe them out completely on each login with another LDM
hook. They're basically kiosks with a full desktop.
For data persistance, we have accounts that are set up with passwords, and use
the guestlogin feature rather than autologin. Users with accounts type in their
username/password, and users without accounts get a temporary login clicking on
the "Login as Guest" button.
