Remote mount permission question

Hi all,

Suppose I mounted a samba or NFS share as root on my local machine
(as root) and the share is owned by user dj group dj who is an
ordinary user on the server. Let there be a subdirectory with
permission 700 under the share that I mounted. Logically, I should
not have access to that directory on the server (since the permision
on the server does not allow access to anyone but the owner.)

However, what I have observed is that the local permission over-rides
the remote permision and since I mounted the share as root, I can do
whatever I want with that directory or any subdirectory of it. Isn't
that a huge security problem? Or am I missing something here?
