              Lightweight Directory Access Protocol (LDAP)
                       Registrations for PKCS #9
                    draft-seantek-ldap-pkcs9-00.txt

Abstract

   PKCS #9 includes several useful definitions that are not yet
   reflected in the LDAP IANA registry. This document adds those
   definitions to the IANA registry.

Internet-Draft         LDAP PKCS #9 Registrations     September 10, 2014


1.  Introduction

   This document registers the LDAP [RFC4510] schema definitions
   [RFC4512] for a subset of elements specified in PKCS #9 [PKCS9],
   including attribute types; matching rules and syntaxes to be used
   with these attribute types; and related object classes.

   As the elements and their semantics are defined in [PKCS9], this
   document needs to be read in conjunction with [PKCS9] to make use of
   the LDAP registrations provided herein. [PKCS9] provides complete
   definitions, with one significant omission: the IANA Considerations
   section was never appended. This document provides the IANA
   Considerations section necessary to register appropriate descriptors.

2.  Syntaxes

   Appendix B.1 of [PKCS9] describes various syntaxes used in LDAP to
   transfer PKCS #9 elements and related data types.

3.  Matching Rules

   Appendix B.4 of [PKCS9] provides matching rules for use in LDAP.

4.  Attribute Types

   Appendix B.3 of [PKCS9] details attribute types for use in LDAP,
   including (by its own admission) attributes that are highly unlikely
   to be stored in a Directory. For parity, all attributes in Appendix
   B.3--but not necessarily in PKCS #9 as a whole--are registered via
   this document.

4.1  Short Descriptors for Certain Useful Attribute Types

   [PKCS9] includes certain attribute types that have found meaningful
   use outside of the PKCS series. Specifically:

      o  emailAddress is mandated in [RFC5750], and has mandatory
         processing requirements if included in a certificate [RFC5280].
      o  [RFC5280] recommends the recognition of pseudonym.
      o  The Qualified Certificates Profile [RFC3739] requires both
         pseudonym and the vital records dateOfBirth, placeOfBirth,
         gender, countryOfCitizenship, and countryOfResidence.

   As a result, certain applications not only encounter and generate
   these attributes in practice, but also use short descriptors that
   have come to be widely recognized.

   As permitted by Section 3.4 of [RFC4520], the short descriptors in

   reflected in [PKCS9]:

         Table 1: Short Descriptors for Certain Attribute Types

5.  Object Classes

   Appendix B.2 of [PKCS9] details a set of object classes for use in
   LDAP.

6.  Security Considerations

   PKCS #9 security considerations (written for the RFC edition) [PKCS9]
   apply to the definitions in this document. General LDAP security
   considerations [RFC4510] apply as well.

7.  IANA Considerations

   The IANA shall register an LDAP Object Identifier [RFC4520] for use
   in this technical specification, and shall update the LDAP Descriptor
   registry [RFC4520], as indicated below.
