BmixvyCdQtgcU1kk1pXYje0zWGyidAnlp0w%3D&reserved=0> "Clarify Certificate
Policies for Sub-CAs"
   - This issue was filed before the Profiles Ballot, and parts of it may no
longer be relevant
   - Trevoli suggests that we review whether this issue is still relevant
offline
   - Aaron volunteers to do so after the call
   - Clint suggests that, even though the exact language referenced in the
second half may not exist anymore, the central concern may still be relevant
   - Ben Wilson reminds us that the anyPolicy OID is dangerous when a root
is approved for EV issuance

jQR5rOz1k5wwxJ%2FvB60WGTs28JikNah9A%3D&reserved=0> "CA is prohibited from
signing own server certs"
   - Original reporter did not sign the IPR agreement, lots of sidetrack
discussion of that
   - Aaron points out that Ballot SC-66 (2023 Fall Clean-Up) addressed this
by adding a sentence to 1.3.3
   - Clint says that he agrees: with that language, the CA is not generating
a key *on behalf of* a Subscriber, but rather *is* the Subscriber
   - The issue is closed

mokM%2BVo67BMYTf5zSghybvveSjjNKRJZ5Es%3D&reserved=0> "BRs: Clarify policies
around notBefore and notAfter for Subscriber and CA certificates"
   - Dimitris points out that this was addressed by SC-62 (Profiles) which
put strict limits on the amount of back- and forward-dating of certificates
   - The issue is closed

bRIf3HQM5R1mHwCBUbmkW9HKLdufQEkiy0M%3D&reserved=0> "BRs: Make
nameConstraints critical"
   - Aaron points out that as of SC-62, Name Constraints SHOULD be critical
   - Clint says that Apple devices are updated to the point that making this
extension critical should be fine
   - Dimitris still has questions about compatibility with old devices
   - Clint confirms that his research indicates minimal to zero risk
   - Dimitris also requests a census of how many CAs are still using
nameConstraints
   - Adriano Santoni also requests research into nameConstraints support in
other platforms like Java, .NET, NodeJS, golang
   - Aaron points out that research could include a census of how many
name-constrained certificates already have the extension marked as critical
   - Trevoli questions the importance of making this change
   - Tadahiko Ito says that making this change is less important now that
Technically-Constrained SubCAs are now audited
   - Wendy Brown asks for clarification on why criticality is important here
   - Tim Hollebeek says that a client which does not understand the
nameConstraints extension would treat a non-critically name-constrained
certificate as unconstrained
   - Clint points out that the BRs' SHOULD is a departure from RFC 5280's
MUST
   - Censys.io indicates that approximately 20% of trusted name-constrained
certificates already have that extension marked as critical
   - Aaron suggests that this means that we would know if these certificates
were broken on various platforms
   - Trevoli disagrees, pointing out that many of these intermediates are
operated by very small CAs
   - Clint says that Apple operates several of these CAs and issues large
numbers of end-entity certificates from them
   - Trevoli says that maybe we should just go ahead and do it, with a
relatively distant effective date, since it won't affect existing SubCAs.
But we shouldn't roll it into a larger profiles ballot, given the
difficulties implementing SC-62.
   - Issue is kept open with next action assigned to Clint Wilson

MqtwcspiVsD2zNQYjGBzjoAJTURmLb%2Bmo%3D&reserved=0> "BRs: Clarify how SRVName
subjectAltNames should behave"
   - Dimitris says that this was discussed in Validation, and that Tim
Hollebeek described it as a "very geeky" problem
   - Tim says that this is more like a feature request than a bug.
Interested in tackling it, but very low priority.
   - Tim says that SRVNames are useful because they can bind name:port
combos.
   - Issue is kept open

for onion domains?"
   - Aaron points out that this has been resolved, Appendix B (2) lists
3.2.2.4.20 as an acceptable method
   - Issue is closed

PAG update
- Ben Wilson was elected chair of the PAG
- An email was drafted by the PAG and sent to GoDaddy requesting
clarification on the intent behind the exclusion notice
- The ballot in question (SC-070) focused on the BRs, while the exclusion
notice focused on the EV guidelines
- GoDaddy's response was requested by Friday May 17
- Another PAG meeting will be scheduled for Monday May 20
- Dimitris points out that the PAG is focusing on the procedural aspects of
the exclusion notice, and has not yet addressed the contents of the patents
themselves

F2F agenda
- Inigo Barreira asks for potential topics to discuss at the upcoming F2F
- No topics suggested at this time

Ballot Status
- SC-073 (Compromised and weak keys): now in IP Review period
- SC-074 (CP/CPS structure): in voting period
   - Tim asks folks to change their vote on this, since he believes it could
use another round of revision, to clarify how precisely section headings
need to match RFC 3647 (particularly with regards to capitalization)
   - Dimitris, as the author of the ballot, points out that the effective
date of September 15 2024 could give us time to fix it
   - Rich Smith points out that RFC 3647 even has internal inconsistencies /
typos
   - Tim says that there's no mechanism for withdrawing a ballot, but votes
can be changed so sufficient "no" votes (especially from Certificate
Consumers) can sink it
- SC-070 (Clarify DTP): in PAG review
- SC-067 v1 (MPIC): Still in discussion period
- SC71 (Subscriber agreement / Terms of Use): Being revised by authors

Any Other Business
- Wayne Thayer has a question about when CAs are required to comply with the
new version of the NetSec requirements
- Dimitris and Ben say that the BRs need a ballot to adopt the latest
version.
- Clint indicates that he had plans to put together such a ballot in June.
Such a ballot would have an immediate effective date, because the new
version of NetSec itself has an effective date in November.

Next meeting
- We do not yet have a finalized agenda for the ServerCert WG meeting at the
F2F
- A draft agenda has been posted to the wiki
- Videoconference on May 23 cancelled due to upcoming F2F

Meeting adjourned
