In the unlikely event that this happens again, boot to single-user mode by typing `-s` at the `boot:` prompt. Then you can re-mount the filesystem as rw and change root's password: fsck -y /dev/hd0a mount -w / passwd root sync reboot Then log in as root at the graphical login prompt and you can use the graphical NetInfo admin tools to list/create/reset regular users. One can also replace/reset the local NetInfo DB entirely by copying `/usr/template/client/etc/netinfo/local.nidb`, `/usr/template/client/etc/hostconfig`, and `/usr/template/client/etc/hosts` over the files at the same paths minus `/usr/template/client`.
