Abstract:
   Experience has shown that it is extremely difficult to deploy proper
   PKIX certificates for TLS in multi-tenanted environments.  As a
   result, domains hosted in such environments often deploy applications
   using certificates that identify the hosting service, not the hosted
   domain.  Such deployments force end users and peer services to accept
   a certificate with an improper identifier, resulting in obvious
   security implications.  This document defines two methods that make
   it easier to deploy certificates for proper server identity checking
   in non-HTTP application protocols.  While these methods developed for
   use in the Extensible Messaging and Presence Protocol (XMPP) as a
   Domain Name Association (DNA) prooftype, they might also be usable in
   other non-HTTP application protocols.
