Not at all, if they are not on the list of admins that require root to do
their jobs, whose processes include a way to routinly change the passwd,
and distribute it in a secure manner <face to face>, then they don;t get
the passwd fer root. Temp needs of root level access can be done through
sudo or similiar tools, and limiting what those users have access to.
anything more requires and admin to do the job and make sure it's done
correctly. Oh, and the help desk is *not* on the list of those to whom
the root passwd should be made available. They may end up distributing it
over the phone or via e-mails to just about anyone that calls for
access....

Thanks,

OK, so you're a Ph.D.  Just don't touch anything.
