I would still prefer identity information (natural person or legal entity, or both: natural person affiliated to a legal entity) to be expressly included in the WG scope since the beginning. Of course this makes the WG task (that of producing "S/MIME baseline requirements") harder and longer, but it would reflect current practice. On the other hand, its not clear to me what the implications would be if S/MIME baseline requirements were approved and published, should they not cover the inclusion of identity information in S/MIME certificates. Would that imply, once Root Programs adopted such S/MIME BRs, that those CAs issuing S/MIME certs with identity information in them are mis-issuing?

    Tim, Wayne, Adriano,

    Apple made a contribution and although HARICA disagrees with most
    of the recommended changes I believe there should be some
    discussion around that.


Agree. It's not in anyone's interests, nor do I believe that the intent was to ignore input unrelated to the identity issue. We should discuss it now to allow members to decide for themselves if the suggestions are important enough to warrant voting against this ballot, or if the ballot is good enough to ratify as-is.

    Unfortunately, although I had started working on a response, I
    didn't have time to complete it on time. I was hoping to see some
    comments/responses from the proposer and endorsers before the
    voting period began.

    For what it's worth, here is a list of my comments (attached). My
    biggest concern is the Certificate Consumer members that qualify
    based on "mail transfer agent". I would certainly like some more
    information about that before HARICA votes. Other than that, the
    charter looks good to me.


The section in question is:

(2) A Certificate Consumer eligible for voting membership in the SMCWG must produce a develop and maintain a mail user agent (web-based or application based), mail transfer agent, or email service provider that processes S/MIME certificates issued by third-party Certificate Issuers who meet criteria set by such Certificate Consumer. The inclusion of "mail transfer agents" as eligible participants doesn't appear harmful to me, but I also agree with Clint's comment that "The role of a mail transfer agent in consuming S/MIME certificates is unclear." Tim or Ben: this was part of the draft Ben proposed over a year ago. Do you have any information on why this was included?


    Best regards,
    Dimitris.

    Based on my recollection of the Guangzhou discussion, and
    supported by the minutes, the "path forward agreed to in
    Guangzhou" was that we would take this charter to a ballot
    without further attempts to resolve the issue of including
    identity in the charter's scope. There does not appear to be a
    path to consensus on this issue, despite the considerable amount
    of time spent discussing it. I'm unhappy with this approach, but
    as one of the endorsers, I don't see an alternative other than
    "take it to a vote" that gets this much-needed WG formed any time
    soon.

        Hi Tim,

        Could you point to where that's reflected in the minutes? Our
        understanding here at Google is that Apple's proposed
        changes, which we support and would be unable to participate
        without incorporating, is that it accurately and correctly
        reflects the discussions in London [1], reiterated in
        Cupertino [2], and agreed upon in Thessaloniki [3]. It
        appears that, following that, the proposers of that ballot
        ignored that consensus and conclusion, and yet the discussion
        of Guangzhou [4] does not indicate there was consensus to do so.

        I'm hoping we've just overlooked something in the minutes,
        but Apple's proposed changes seem imminently reasonable, and
        a worthwhile path to drafting requirements that consuming
        software, such as mail clients (both native and Web), can use
        and consume as part of their root programs, as an alternative
        to their root-program-specific requirements.

        "Dean – We have a blank slate here and it seems the
        reluctance was to make it a narrow scope and then focus on
        either one aspect of SMIME. First task might be how to
        validate an email, and then focus on identity validation.
        Some comments were to make the chart narrow to focus on one
        task while others say to include all proposed tasks to not
        have to recharter which has caused issues in the past."
