Does /etc/master.passwd have entries for all of your non-root users? If so, then probably all you need to do is regenerate your password database. The easiest way to do this is run "vipw", make some kind of change (and undo the change -- this is just so it thinks the file has been changed) and exit. Your password database will be regenerated. -- Matt Emmerton
