That #is, suppose I (pcl) am approached by jruser to change their password. #I type something like: # % \/bin/su - root # Password: # # npasswd jruser # ... # #If I make a typo at this point, and have to have another go at #changing jruser's password (still in the same invocation of npasswd, #BTW) and succeed in getting a password through, I *sometimes* find #that root's password has been changed and the user's has not. My #password is left unchanged. (Phew!) I have not experienced this on Suns (yet!). This is running the pw_yp.c code to update NIS passwords if there is no local password. The main hacks I have made are to update a separate NIS password age database if a NIS password has been successfully changed. Mark
