Are you logging in as an administrator? Administrators can see all files,
even if the permissions have a deny for read. This behavior was done to
prevent files from becoming locked in an invisible mode. If it were
possible to make a file invisible to everyone, it would be locked that way,
because nobody would be able to set it back to visible.
