not to change root password

I posted something similar yesterday... Here it is again:

Cmnd_Alias      PW=/usr/bin/passwd [!-]?*, /usr/bin/passwd -f?*
Cmnd_Alias      PWR=/usr/bin/passwd *root*


The PW command alias allows the user to change passwords but with no
switches apart from -f (which on Solaris forces a change at next logon),
and PWR allows the user to change the root password.

MAILACC can run PW but not PWR !  I think this is what you are trying to
achieve.  You could do the same for the other commands.

Subject: not to change root password

in /etc/sudoers, we have the following for helpdesk users:

HELPDESK  ALL = /root/data/, /usr/bin/passwd, !/usr/bin/passwd root

it seems that though i have specified that they can't run "sudo 
passwd root", they can still change root password by running 
"sudo passwd".  how do i fix this?  i want helpdesk to be able to 
change other user's passwords but not root's.
