KILL ME
So we're moving from a scattered UID format to a NIS format. On the way to the party, we discovered a couple of machines have their own ideas what everyone's UIDs are, and they all differ from NIS.
This might help.
# find . -uid 1020 -exec ls -l {} ;
And once you get your uid and gid maps done (beware intermediate collisions: ie you can't change 500 to 600 if you have not already cleared 600!)… if you feel lucky:
# find . -uid 1020 -exec chown 255 {} ;
# find . -gid 2000 -exec chgrp 500 {} ;
