Thanks, Michael

Brian,

At IETF106 i thought if Bens review would remove all discuss, we would have
finished IESG review, but that is not the case because two of the
IESG members that had approved ACP draft have since left office, so
their votes do not count. I did report that at ANIMA WG @IETF106.

At IETF106 we had both the ACP report from me of -21, as well as Ben's
presentation on the main issue he saw, the encoding of the ACP
domain information field in the certificate.

While i had hoped that the in-person discuss about that issue would
resolve that discuss because we did explain all the argments for it,
his discuss of -21 on 12/30/2019 did i think not change his position,
instead it also mentioned IPsec experts supporting that view, but
without a technical explanation why, or who all those experts where.

In January, i worked on -22 to answer to Bens review of -21. which i
published 02/03/2020. For the encoding issue i rewrote the bullet
points justifying the choice of encoding, primarily pointing to the
fact that rfc822 names are nowadays quite common identifiers in a
lot of e.g.: web systems, in addition to all the benefits of avoiding
new or extensions to certificate parsing libraries and the like.

Through IETF106 and writeup of -22 i even think more this
is a pragmatic, prudent and logical choice, and i couldn't find
anything in the cert related RFCs i read that seemed to contradict this for me.

In February, Ben had told me, that -22 resolves his other points,
except that that he continues on his position re. the encoding.
But there was also security profile work improved in -22.

Shortly after IETF 106, Eric Vyncke took over as sponsoring AD for
ACP. He provided a review with 72 comments in january to the authors.
After i finished -22, i worked on these 72 points through february and posted
-23/24 last week.

In addition, during february, i also started to reach out to IPsec
mailing list to further discuss details of the proposed enhancements
to the IPsec profile. I ran out of time last week, and plan to
finalize those fixes quickly (together with the WG fix sugestions i
received for -24).

In addition, i will also reach out directly to the IPsec experts
i know and ask for the rfc822name encoding. I did that already
last year, but never received replies.

Eric told me, he wants to put ACP back onto the IESG agenda for April,
and this would result in a new IETF review.

Thats all i know.

Cheers 
    Toerless
