Well, I wouldn’t do this on a production machine, but seeing as it’s a testing server on your powerbook…. try playing with the nidb a bit – you can either try restoring your previous local.nidb from /var/backups, or whip the feet right out from underneath it, and completely remove the nidb – take a note before you do this about UIDs and usernames that exist in your nidb. I can’t stress enough that this does of course have the potential to completely wreck your testing machine, but as you can’t log in at the moment, and it’s a testing server, I’d play with it just for fun! If this is all new to you, there’s several guides around for reinstating your nidb from backup – just google it. And if it all falls down around you, you still have the image that you created your testing powerbook from in the first place, restore and start again… 🙂
