Some REALLY quick comments from a brief read: First, I think this is pretty clearly standards track, especially since I expect the authors are willing to work together with the IETF community and respond to feedback, and it includes normative requirements that are intended to be used with a major ecosystem, the WebPKI.
3.1.1. recommend clarifying the extent to which case matters. How should "TRUE" or "True" be handled? 4-5. This is WAY in the weeds, and possibly should just be ignored, but there's actually no requirement that the CA is able to host content at the domain specified in the CAA tag. At a minimum, they're only required to have permission from the domain owner (RFC 8659, first paragraph, item 2, second clause). This might actually even happen due to acquisitions. In such situations, a CA might actually be unable to host content on a .well-known URL for a tag it uses. I don't think 8.4.1/2 is in scope or makes the document better. There are a wide variety of contractual solutions here, and how a user agrees to a particular CA's terms of service is not a relevant topic for IETF. -Tim > -----Original Message----- > From: Acme <acme-boun...@ietf.org> On Behalf Of Mike Ounsworth > Sent: Thursday, July 6, 2023 10:54 AM > To: acme@ietf.org > Cc: Paul van Brouwershaven <paul.vanbrouwersha...@entrust.com> > Subject: [Acme] FW: [EXTERNAL] New Version Notification for draft- > vanbrouwershaven-acme-auto-discovery-00.txt > > Hi ACME! > > This is new business that we would like to add to the agenda for 117. > > Thanks, > --- > Mike Ounsworth & Paul van Brouwershaven > > -----Original Message----- > From: internet-dra...@ietf.org <internet-dra...@ietf.org> > Sent: Thursday, July 6, 2023 9:39 AM > To: Mike Ounsworth <mike.ounswo...@entrust.com>; Paul van > Brouwershaven <paul.vanbrouwersha...@entrust.com> > Subject: [EXTERNAL] New Version Notification for draft-vanbrouwershaven- > acme-auto-discovery-00.txt > > WARNING: This email originated outside of Entrust. > DO NOT CLICK links or attachments unless you trust the sender and know the > content is safe. > > ________________________________________________________________ > ______ > > A new version of I-D, draft-vanbrouwershaven-acme-auto-discovery-00.txt > has been successfully submitted by Paul van Brouwershaven and posted to > the IETF repository. > > Name: draft-vanbrouwershaven-acme-auto-discovery > Revision: 00 > Title: Auto-discovery mechanism for ACME client configuration > Document date: 2023-07-06 > Group: Individual Submission > Pages: 16 > URL: https://www.ietf.org/archive/id/draft-vanbrouwershaven-acme- > auto-discovery-00.txt > Status: https://datatracker.ietf.org/doc/draft-vanbrouwershaven-acme- > auto-discovery/ > Html: https://www.ietf.org/archive/id/draft-vanbrouwershaven-acme- > auto-discovery-00.html > Htmlized: https://datatracker.ietf.org/doc/html/draft-vanbrouwershaven- > acme-auto-discovery > > > Abstract: > A significant impediment to the widespread adoption of the Automated > Certificate Management Environment (ACME) [RFC8555] is that ACME > clients need to be pre-configured with the URL of the ACME server to > be used.
