Betreff: [Servercert-wg] Voting Begins: Ballot SC16: Other Subject Attributes
Purpose of Ballot:

This ballot intends to clarify requirements placed on Subject attributes in Subscriber certificates in BR section and EVGL section 9.2.8. Specifically, Subject fields must contain more than just metadata if they are present in a certificate. The OU field is permitted in EV certificates, but no unspecified Subject attributes are permitted.

The following motion has been proposed by Wayne Thayer of Mozilla and endorsed by Doug Beattie of GlobalSign and Tim Hollebeek of DigiCert.


This ballot modifies the “Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates” as follows, based on Version 1.6.3:

Capitalize the heading of Baseline Requirements section 7.1.4 Name Forms

Add a second paragraph to Baseline Requirements section as follows:

Subject attributes MUST NOT contain only metadata such as '.', '-', and ' ' (i.e. space) characters, and/or any other indication that the value is absent, incomplete, or not applicable.

Replace Baseline Requirements section, in its entirety, with the following text:

j. Other Subject Attributes

Other attributes MAY be present within the subject field. If present, other attributes MUST contain information that has been verified by the CA.


This ballot modifies the “Guidelines For The Issuance And Management Of Extended Validation Certificates” as follows, based on Version 1.6.8:

Replace EV Guidelines section 9.2.8, in its entirety, with the following text:

9.2.8. Subject Organizational Unit Name Field

Certificate field: subject:organizationalUnitName (OID

Required/Optional: Optional

Contents: The CA SHALL implement a process that prevents an OU attribute from including a name, DBA, tradename, trademark, address, location, or other text that refers to a specific natural person or Legal Entity unless the CA has verified this information in accordance with Section 11. This field MUST NOT contain only metadata such as '.', '-', and ' ' (i.e. space) characters, and/or any other indication that the value is absent, incomplete, or not applicable.

Add EV Guidelines section 9.2.9, with the following text:

9.2.9. Other Subject Attributes

CAs SHALL NOT include any Subject attributes except as specified in Section 9.2.


This ballot proposes a set of Final Maintenance Guidelines.
