The IESG has approved the following document: - 'A Property Types Registry for the Authentication-Results Header Field' (draft-ietf-appsawg-authres-ptypes-registry-04.txt) as Proposed Standard This document is the product of the Applications Area Working Group. The IESG contact persons are Barry Leiba and Pete Resnick. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-appsawg-authres-ptypes-registry/ Technical Summary RFC7001 defines the email Authentication-Results header field that presents the results of an authentication effort in a machine-readable format. The specification in that document enumerated a small set of types of properties that can be reported using this mechanism. That constrained set of types has proven to be too narrow. Accordingly, this document updates the specification to allow for additional property types ("ptypes") beyond the original set, and creates a registry where new ones can be listed and their defining documents referenced. As an update to RFC 7001, this document is appropriately placed on the standards track. Review and Consensus This is a simple document and WGLC was quiet (no comments). There was significant discussion prior to WGLC with reviews and comments from three different reviewers. The only significant technical issue that was discussed was the possibility that the version number of the field might need to be increased. The unanimous conclusion was that it does not. This draft is a precursor to draft-martin-authentication-results-tls. Once this document relaxes the ptype constraint, other authentication types such as TLS (mentioned above) are expected. Multiple participants reported plans to implement these. Personnel The document shepherd is Scott Kitterman. The Responsible Area Director is Barry Leiba.
