You don't _have_ logins directly to 4000 machines. You have a central admin
host (or five) with user-level accounts. Those user-level accounts can 'sudo
ssh <target>' to accomplish things as root on the remote boxes. Given the
nature of the UNIX permissions structure, any solution is going to be lacking
when scaled up large enough - but the problems involved in properly
administering sudo are considerly smaller than those introduced by having
mulitple uid 0 accounts (especially multiple uid 0 accounts on multiple
machines).

What do you do when one (or ten) of those 'interchangeable syadmins' leaves
the company? _Then_ you have a real nightmare - changing root and removing
uid 0 accounts on 4000 boxes. I'd rather manage /etc/sudoers, thanks very
much.

All of which can be handled with sudo, without giving away the keys to the
castle.

Not dogma, just best practice.
