Restored Image can’t login

Hey, I restored my server image to a 12 inch powerbook for some testing. Everything went well until I tried to login. Nothing I try works. I booted into single user and tried passwd. Found a few references to closing this security hole and a few mentions of not wanting to post how to do it. To me physical access is physical access. If I can login to this powerbook I will have a test bed for my LDAP conversion. I'm at 10.3.9 will go to 10.4 after I can test the upgrade on my powerbook.
