4. Validation Subcommittee Update

Corey Bonnell said that the group met last week and first discussed the face-to-face meeting. They will work on finalizing the certificate profiles ballot and continue analysis of the use of Applicant and Applicant Representative. They merged a profiles ballot pull request from Dimitris. They continued analysis of the defined terms Applicant and Applicant Representative and identified a number of opportunities for improvement. They will continue at BR section 4.3 at the face-to-face meeting.

5. Ballot Status

Ballots in Discussion Period

6. Any Other Business

Update on elections for SCWG

Jos said that Inigo Barreira has been elected as the next chair and will begin in November. There have been no nominees for vice chair.

Support for multiple OU fields in CA certificates

Dimitris said that he sent a link to a pull request that would permit multiple OU fields in CA certificates to the list. The current BRs don’t restrict the inclusion of the OU field in CA certs, but the profiles ballot does. However, research on existing certificates found no CA certificates containing OU fields. Given this, Dimitris proposed that we should add language to the profiles ballot to prohibit the OU field in CA certificates. Dimitris plans to create a new PR that will disallow OU in CA certificates. Doug Beattie asked about rules for other Subject fields. Dimitris said that the profiles ballot does contain some minor normative changes, but more substantial changes should be discussed and balloted separately. Doug asked if the change would apply to roots or cross-certificates? Dimitris said that he would have to check. Corey said that he recalls there being a carve-out for cross-certificates. He also noted that this would affect ICAs that chain to roots trusted for TLS. Dimitris said that he will review the requirements and we can continue the discussion at the face-to-face meeting. Mads Henriksveen asked where to find the BR redline and Corey said that the same link shows both the EVGL and BR redlines for the ballot.

Jos thanked everyone for their support during his time as SCWG Chair.
