Unhappy Lost my LDAP leases

We've got ldap running on our Ubuntu 8.04 server. Yesterday, while ifconfigging some machines, I was moving around the room a lot and eventually, due to lack of concentration and general stressedness (the library staff are such a pain in the neck!) I wound up with several ldapvi editors open simultaneously.
I didn't even realize the problem this caused, until I got a call from a professor who could no longer log into her desktop. A certain IP range requires LDAP authentication to log in, and when your machine is not in that IP, using your LDAP login won't get you in, of course. I got into her machine and realized her IP had changed. It's not supposed to do that. I checked our dynamically created DHCP list (updated by: sh -x /root/bin/ and saw that most of the machines had become unregistered from LDAP.

The dhcpd log shows a whole bunch of these errors:

Sep 15 15:48:38 firewall dhcpd: DHCPREQUEST for <IP#> from <MACAddr> via eth1: unknown lease <aforementioned IP#>.
The first time this error shows up is Sep 15 15:30:52, according to the dhcpd log. Is there anyway at all for me to do something like a rollback to that point in time, to reverse this whole mess? :-(

Did the editor create various invisible backup files you can use to recover the original configuration?
