Oh really? This means that if you get a reject, and you know it isn't
one of your previous passwords, it >MUST< be someone else's! Then
you just try each login on the system until you hit the one who's
password you have just "guessed". This seems rather bogus. 
The passwd program should not give out ANY information 
about other users' passwords, even to the extent of
"you have just used a word nobody else is using".

Security is YOUR job, too!
