No, it has more to do with the fact that we have to audit all attempts to 
modify trusted databases - in this case, shadow. No one can use these tools 
since they do not have the permissions required to be successful. So, we 
remove the ability to use these tools so that we don't have to audit it. 

IOW, if we open the permissions, we need to make these become setuid root so 
that we send audit events saying they failed.

Its not so much a security thing as much as its a certification thing. An 
ordinary user cannot possibly use these tools since they do not have the 
requisite permissions.
