2025-09-25 Minutes of the Server Certificate Working Group
September 25, 2025 by Wayne ThayerMeeting Date: 2025-09-25 Note Well: Read by Wayne Thayer during the SCWG call preceding this call. Review of Agenda: No additions or changes. Approval of Minutes: September 11, 2025 Teleconference (Draft minutes were distributed on 2025-09-11) approved. The minutes from the April 10, 2023 meeting are still pending. Action Item: Dean Coclin will resend the meeting recording to Aaron Poulsen to assist in completing the minutes. Working Group Updates Server Certificate WG (Wayne Thayer): The last meeting discussed the sunset of pre-certificate signing CAs, with the effective date moved to March 15, 2024. Validation Subcommittee (Corey Bonnell): The group discussed definitions for “Authorization Domain Name,” “Base Domain Name,” and CNAME chaining. A future ballot will be drafted to clarify these terms. The next meeting will cover IP address-based validation and F2F meeting topics. Code Signing WG (Martijn Katerbarg): Ballot CSC-31 is in discussion and will be restarted soon with minor changes. S/MIME WG (Martijn Katerbarg): The last meeting was dominated by a discussion on the use of pseudonyms in the Common Name, with differing opinions. A discussion was also held on potentially re-allowing the OU field in S/MIME certificates. NetSec WG (Clint Wilson): The group had a brief discussion on the potential use of AI as a tool for monitoring incidents, ballots, and certificate validation workflows. Clint suggested this is a broader Forum-level topic. Definitions & Glossary WG (Tim Hollebeek): Work is resuming to create a standalone definitions document and resolve circular references. Ballots are being organized. Forum Infrastructure WG (Ben Wilson): The group discussed GitHub governance, including the Contributor License Agreement (CLA) and comment moderation. They concluded that these are policy decisions for the full Forum. IPR Subcommittee (Ben Wilson): A final redlined draft of the IPR Policy v1.4 is complete and will be circulated to the public list for review. Any Other Business: Fall 2026 F2F Meeting: The host and location have been changed. The meeting will now be hosted by eMudhra in Vienna, Austria. Scott Rea from eMudhra requested that members share any known scheduling conflicts for the October 2026 timeframe.
