Machines that ARE NOT using DHCP when up:
zeus
cerberus
balthasar
caspar
masterhand (shouldn't use DHCP)

Machines that ARE NOT showing up on the DNS when up (and using DHCP):
box (Damn Small Linux)

Machines that ARE using LDAP Authentication:
deadowlsurvivor2
masterhand

For the Ubuntu boxes, local accounts take precedence over LDAP accounts
by default, though if the passwords are mixed, either one will work.

If someone else will add PAM and NSS (which are on the clients) to the
conversation, I'd appreciate it (just had my buzz killed).
