The first correct answer is the following, thanks to all those who responded. (Gary Richardson)

His message:

->Bingo, you hit it the nail right on the head with this line:

>BTW, we have been running npassswd for the last 6 months,

->You are no doubt running the *normal* version of npasswd, and not
->the YP version. This happened to me. I had the normal version, and
->I thought people were screwing around on my machine, so I changed
->the root passwd. heh, as SOON as I changed the password, I checked
->the /etc/passwd file. I contained the ENTIRE passwd entry for
->everyone (I was using the +user convention).

->Recompile your npassswd to be the YP version and this won't happed
->to you.

Thanks all,
