Authentication Dialog

[n2arkitektur]

I am cleaning up my old computer to prep it for resale, which Apple seems to have made very difficult in Snow Leopard. I have removed all personal files, removed passwords from the keychain, reset the keychain, reset the admin user name & password, and completed a 7-pass erase of deleted files. Everything is clean. However, the authentication dialog is still autofilling my old user name. As I've deleted everything in the keychain & reset the admin user name, I'm not sure where it is pulling this from. Is there anyway to reset this? I have scoured the internet to no avail.

Put in your OS install disk perform full fresh install when you go to reboot at the end of the install shut down the machine then once the person buying turns it on it is like they have new Mac fresh from factory which they can enter in their own settings for with none of your information left on it.
