NIS/YP hole

[ultima () CORINNE MAC EDU (ultima () CORINNE MAC EDU)]

SCO OpenSERVER 5 exhibits a similar hole, the default login program doesn't prompt you for old passwd once it has 
expired. And with the many passwd-file-stealing-exploits its not hard to get the file, then analyze it to find which 
accounts have expired passwords (This data is kept in the last few characters of the password field). This is a pretty 
big hole, and jack0's post reminded me of it...
