You started this thread a couple of times, it seems ;-)

IF you are NOT on a trusted system, the encrypted passwords are in the passwd file, so you could try to edit a copy (repeat,a copy!) of the file. Quick and dirty thing I just glued together on my linux box:

for i in `cat userlist.txt`; do cat passwd.copy | sed -e "s/^\($i\):.*:\(.*:.*:.*:.*:.*$\)/\1:r4hRJr4GJ4CqE:\2/" > passwd.copy; done

--> userlist.txt contains the usernames to 'reset', one per line.
--> passwd.copy is a copy (!) of the passwd file.
--> r4hRJr4GJ4CqE is an encrypted password, obtained by changing one user's password and recording the encrypted string from the passwd file.

After running the command, all users which were in userlist.txt should have this same password entry in the passwd copy.

The command seems to do what I want on my linux box. If you want to try it, test it extensively on COPIES of the file, and check everything thoroughly.

Again, this could only work on a system which has its passwords in /etc/passwd (NOT on a trusted system).

DON'T try this blindly on your live system ! It might turn out not be a good idea just as well. Make a few test users first or something..

Oh yea, and don't hold me responsible should careless fiddling with your passwd file get you into trouble ;-)

Good luck !

Cheers
