[CentOS] Changing system users pass via webmin

OK, I really appreciate the time and help of all you guys... got good tips!
Anyway let me tell you that webmin allow to define webmin groups/users in
order to give them granular access to specific modules, in this case only
the "system - change password" option. So there is no way the user change
what he must not (or what you allow them to do)
I came here because I posted the question in samba and even webmin lists
with no success, and anywhere you can find someone that can helps in linux
Sorry if maybe I asked the wrong question in the wrong list or somebody
wasted time reading or researching about this post.

I am very well versed - I have both Webmin and Usermin and I *do* use 
them - the question did not belong here so I tried to (politely) steer 
the OP away in the right direction (and to do some research).

They're tools that I'd rather not let users have access to.....anyhow, 
that's just my paranoid side showing.....longer experience than I care 
to remember (or admit to!) has taught me that *some* users will fiddle 
around with stuff they don't understand.....and then I get blamed when 
it's broke!

If you look at the time on my original reply you'll see it was made at 
05:20 BST......I wasn't exactly wide awake at the time as I was only on 
my 1st coffee and so only one of my two brain cells was working! :-)
