The naive client has to operate off applications, not policies. So
look for the key that is labeled for use with S/MIME or whatever you
want to use.

The configuration you propose is not one I believe is suited to the
completely naive client where surely chaining with the Validate service
doing the locate would be the configuration of choice.

What is the point of having the client do a Locate if it does not have
any comprehension whatsoever of the data returned?
