RE: Admin previleges



Hi Gary 

Thanks for your reply.

	Ya, Actually I want one administrator to restrict the privileges
of 	other admins. 

	All admins are part of "admin" group.  Is there any way in Mac
to get  
	hierarchy of administrators?

	The actual requirement for me is that I don't want other admins
to 	kill some process. (Specially root processes) and I also don't
want 	them to change some of the system preferences.  Can you suggest
me 	some way to come out of this problem?  In other words, I want
one 	admin which can be treated as super admin by me and which has
privileges little more than the other admins.

	Also what I have noticed in Mac is that one admin can any time
delete 	the other admin's account from system preference. Which I think
is not 	logical. Because if as an Admin I create another admin so this
new 	admin should not be able to delete at least my admin's account
from 	system preference. Whats your opinion on this?

	How can I do this? When we create new admin account from system
preference, then for each account new group is created . Though every
admin user is part of admin group . 
	So can I apply your above suggestion to these kind of admins??

	Can you pls elaborate above mentioned point . I couldn't get it
clearly.


Hope to get some help from your side . 

Thanks and regards,
Nidhi

What do you mean by "disabling the root account"?

The root user by default has no password (*not* an empty password) in  
Mac OS X.  It would therefore be a little difficult to require "the  
root password" to do anything.  :-)

Do you really want a hierarchy of administrators, or do you want to  
divide up administrative responsibilities (and authority, and blame)  
among a group of administrators?

The Authorization subsystem allows an administrator (with full  
superuser privileges) to configure parts of the system according to   
groups (man group(5)).  You could, in theory, assign various  
Authorization-gated activities to different administrators if each of  
the administrators was in his/her own group.

That said, this partitioning would only apply to activities governed  
by the Authorization subsystem.  Otherwise you're back to the usual  
possibilities--filesystem permissions and ACLs are all that come to  
mind in my pre-coffee stupor....
