Restricting changing passwd

[Ritesh Raj Joshi]

HI all!
I am using CU Sudo version 1.5.3 and trying to restrict users from
changing passwd of other collegues.
I have successfully done this for "root" with  !/usr/bin/passwd root .
But how do I restrict for a list of users without having to repeat the
above mentioned command for each and every user.
Is there some kind of wildcards or aliasing that can be employed here.
Thanks in advance ...

Rgds,
