The IESG has received a request from the RADIUS EXTensions WG (radext) to consider the following document: - 'Data Types in the Remote Authentication Dial-In User Service Protocol (RADIUS)' <draft-ietf-radext-datatypes-06.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-08-17. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract RADIUS specifications have used data types for two decades without defining them as managed entities. During this time, RADIUS implementations have named the data types, and have used them in attribute definitions. This document updates the specifications to better follow established practice. We do this by naming the data types defined in RFC 6158, which have been used since at least RFC 2865. We provide an IANA registry for the data types, and update the RADIUS Attribute Type registry to include a "Data Type" field for each attribute. Finally, we recommend that authors of RADIUS specifications use these types in preference to existing practice. This document updates RFC 2865, 3162, 6158, and 6572. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-radext-datatypes/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-radext-datatypes/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references.
