Your selections from my post managed to obscure the fact that I was making
more than one point. I did _not_ state that the ssh key mgmt system outlined
above exemplifies least privilege. I was merely making a comparison between
that model and the topic under discussion, central
administrative/authenticating authorities. Additionally, the section higher
up regarding least privilege was in connection with OS design, and was quoted
from another author's presentation at ToorCon last year. You're stringing
together statements on disparate subjects and then jumping to conclusions.

Please do not put words into my mouth.
