Based on our description, I believe your intent is also to cover Section
The concern raised in Raleigh that this introduces is that it effectively
forbids Enterprise RAs from managing the validation of domains beneath the
Domain Namespace that the CA has verified. This is because Enterprise RAs
are Delegated Third Parties.
Is your intent to restrict such Enterprise RAs to only performing Subject
At present, 188.8.131.52 (nor the proposed updates in Ballot 190) permit blanket
authorizations by Domain Namespace. I suspect that if Section 184.108.40.206 were
modified to permit the validation of such requests at the Domain Namespace
level, and the corresponding reuse of such information permitted, then the
meaningful benefit of an Enterprise RA could be met without the necessity
of introducing the concept.
That is, if 220.127.116.11 were worded to somehow suggest that:
"The CA SHALL confirm that, as of the date the Certificate issues, the CA
has validated each Fully‐Qualified Domain Name (FQDN) listed in the
Certificate using at least one of the methods listed below, or is within
the Domain Namespace of a Fully-Qualified Domain Name (FQDN) that has been
validated using at least one of the methods listed below. "
Then this might be able to satisfy the concern over Enterprise RAs. It
changes the relationship from permitting an Enterprise RA to have
unconstrained issuance, but contractual restriction, to being one of
technical restriction, by requiring that for every FQDN, the CA validate it
is within the Domain Namespace of a (potentially previously) validated FQDN.
