Certificate+Discovery+for+Direct+Project+Implementation+Guide

Overview
This Implementation Guide addresses the use case for discovery of digital certificates for the Direct Project using a hybrid approach based on DNS and LDAP. The Direct Project DNS Configuration Guide addresses the discovery of digital certificates stored in DNS CERT records. The hybrid approach to discovery of digital certificates extends the work described in that document to enable the universal discovery of certificates via LDAP services.

Briefly, this guide's approach for Direct Project certificate discovery is:
 * 1) DNS is used as the entry point leveraging its global discoverability
 * 2) LDAP is used when the DNS record does not support the CERT record or when LDAP is preferred by the publisher
