While I'm not sure it is possible with this particular
file format, in general silently ignoring errors when
reading data that says who is and isn't allowed to access
data seems like a really bad idea.
(Does authz support a deny directive?)
What if because of the error bad_guy_jones now has access
to data the administrator thinks he has protected... and
the error was silently ignored so the administrator has no
idea that there is a problem.
Thanks,
