Hi Rick, 

 

I'd endorse such an amendment. The original intent of the language was to
prohibit DNS Names in the certificate.  However, even if we remove 9.2.2,
domain names are still prohibited under Section 11.6.

Subject: [cabfpub] Possible error in EV Code Signing document

 

While looking over the EV Code Signing Guidelines
(https://cabforum.org/EV_Code_Signing_Guidelines_v1_1.pdf), I came across
what I think is a typo.

 

"9.2.2  Subject Alternative Name Extension

This field should not be included in the EV Code Signing Objects."

 

Section 9.2 is all about Subject DN fields, so it seems a bit odd that 9.2.2
should be about an extension. But as Section 9.7 says "the  Certificate
MUST  include  a  SubjectAltName:permanentIdentifier". 

 

I think 9.2.2 is there because it was copied from the EV SSL Guidelines. In
that document, we explicitly call out subjectAltName in the Subject DN
section to call attention to the fact that we're deprecating the Common Name
field, and want the subject's name instead put in the subjectAltName
extension.

 

I think the way to correct this is to remove Section 9.2.2 (it just consists
of the one sentence shown above).

 

Anyone disagree? Should I create a ballot for this?

 

-Rick
