You are running into the classic authorization vs. authentication
I'm not sure that I will be in your timeframe but the primary focus of
the Hurderos Project was to develop a fine grained authorization
system to solve problems such as this. The project focus has been to
implement the authorization checks via PAM in order to expedite field
deployment of authorization enabled software.
We have a Hurderos enabled sudo utility that makes it possible to
remove administrative user rights by simply disabling the SUDO service
for that identity. The example of root access is also why work
focused on developing a system which could securely differentiate
between a generic and machine specific authorization.
The licensing issues have finally been resolved. I don't know whether
everyone will agree with them but the code will be available which was
my primary goal.
I'm headed to an obedience trial with my Golden Retriever Iggy this
weekend. If I can convince him to drive I hope to have a hurderos.org
website up in the near future.

Drop me a note if you would like a copy of the white paper which
describes the authorization technology more completely. Otherwise it
will be up on the new website shortly, for some definition of shortly.
Best wishes for a pleasant week.
