    abstract =  {This document specifies a TLS extension that enables clients to send generic user mapping hints in a supplemental data handshake message defined in RFC 4680. One such mapping hint is defined in an informative section, the UpnDomainHint, which may be used by a server to locate a user in a directory database. Other mapping hints may be defined in other documents in the future. {[}STANDARDS-TRACK{]}},
