[help!] can't login after a forced shutdown

  1. Yesterday I forced a shutdown on my iMac G5.
    Today I can't login: it appears a different login window (it seems two windows getting over each other) and it don't accept my password!

    I did a reboot by my install dvd and I repaired the disk and the permissinons it (there were errors) but it didn't solve my problmem.

    Then I did another reboot for resetting the password (I didn't forget it) but when I choice the disk it tells me "no available users", so I can't reset anything. The log install output is:

    localhost : Open /Volumes/iMac G5/var/db/netinfo/local.nidb failed : No Root Record in Datastore

    I can't go on and I'm a little be worried about it.

    Thanks in advance for the help
    and please excuse my poor english :)

  2. Your Netifo database, a vital system file that contains information about the users on your system, got clobbered.

    You will need to re-install Mac OS X from your install DVD. Use the "Archive and Install" option. (This will not delete any of your data or programs.)

  3. FWIW, http://iwiring.net:8000/ has the following tip at -- 28 November 2006 HowTo change a lost Mac OS X root password w/o using the Installer DVD

    Boot into single user mode and then:

    % mount -uw / % nicl -raw /var/db/netinfo/local.nidb create /users/root passwd `openssl passwd newr00tpass` % reboot

    The above will replace the root password in NetInfo with a standard 'crypt' style password. For good measure after rebooting reset it using an appropriate tool to a shadow password.

    Sorry I can't give the direct URL... iwiring.net is strange and the long direct URL doesn't work for me.
