Ballot Contents
Purpose of Ballot
This ballot adds a new ACME domain validation method. This method is similar to the ACME dns-01 challenge, but it solves a significant problem. Organizations often run their services on multiple cloud providers, Each of these cloud providers typically automates the section 3.2.2.4.7 DNS validation method by asking the organization to delegate a CNAME record to the cloud provider. Unfortunately, the ACME dns-01 challenge hard-codes the prepended label on the validation domain name as “_acme-challenge”, and DNS standards only allow one CNAME record per zone, thus creating the conflict that this new method resolves.
A draft RFC that addresses this problem was originally published in 2022. It has gone through a few iterations, ending up at the current draft.[1] The mechanism for making the validation domain name unique uses an additional prepended label that is calculated from the ACME account ID. This approach was taken because it aligns the new method with similar domain name validation techniques documented by the DNS Operations WG [2] (note that the scoping mechanism from the DNSOP draft has been removed because it adds unnecessary complexity and scope creep here).
This ballot references the current stable version of the draft RFC. Once the draft becomes an official RFC, a subsequent ballot will be prepared to update this method to reference the final RFC.
