There used to be an MSDN article on "Computing Effective Rights" but my
bookmark seems to be dead now :-(
Microsoft has a "preferred ordering" of ACEs which tells you to always put
denied ACEs before allowed ACEs in an ACL. See the bottom half of
curity/order_of_aces_in_a_dacl.asp?frame=true. This is probably why they
don't mention this case, since it doesn't normally occur.

We wrote several win32 test applications to test conformance. Also the NT
ACL <-> POSIX ACL code in samba that Jeremy wrote computes effective right
similarly, if I remember right.
