  1. LDAP Standardization Report Kurt D. Zeilenga kurt@openldap.org

  2. Standards Development Organizations • IETF • LDAP Revision (LDAPbis) • LDAP Extensions (LDAPext) • LDAP Duplication/Update Protocols (LDUP) • LDAP Directorate • ITU and ISO/IEC JTC1 SG • Open Group Directory Interoperability Forum

  3. OpenGroup’sDirectory Interoperability Forum • Directory Certification Programs • Servers: LDAP Certified • Clients: LDAP Ready • Are developing DSML certification programs

  4. ITU & ISO/IEC JTC1 SG • X.520 matching rule internationalization • What’s a space? • How is case ignore matching to be done? • Which normalization algorithms is to be used? • How is transliteration (T.61/Unicode) to be done? • Misc LDAP alignment • Targeted for 5th edition of X.500 (2005?)

  5. IETF New LDAP RFCs • RFC 3377: LDAP Technical Specification • RFC 3383: IANA Considerations for LDAP • RFC 3494: LDAPv2 to Historic • RFC 3352: CLDAP to Historic

  6. IESG Approved I-D • In RFC Editor’s queue: • draft-ietf-policy-core-schema: Policy Core LDAP Schema • Tentatively approved • draft-zeilenga-ldap-collective/subentry/draft-legg-ldap-gser: Collective Attributes

  7. LDAPbis Status • Revised TS may be done this summer • What next? Revise extension TSs?

  8. LDAPext Status • Basically shutdown. WG cannot formally conclude because “Locate” I-D is before the IESG. • Locate I-D likely to be returned to WG • WG needs to determine how then to proceed

  9. LDUP • LCUP (content sync) work: two proposals • “LCUP” – requires histories, requires limited “system schema” knowledge, overly chatty • “LDAP Sync” – requires no histories, requires “system schema” knowledge, chatty • LDUP(multi-master replication) work stalled, WG wants to publish existing I-Ds as Informational and then shutdown. WG considering how to proceed.

  10. LDAP Directorate • Provides comments to IESG, IAB, and WG chairs regarding Individual and non-LDAP-WG LDAP I-Ds • Composed of the 6 LDAP co-chairs, selected experts, and the Applications Area Directors. • Not a review board, that’s the IESG job

  11. LDAP in other WGs • PKIX: LDAP PKI Schema, ;binary revision, certificate matching • KRB-WG: KDC Administration over LDAP • CRISP

  12. Key Individual Drafts Legg: X.500 ACM in LDAP, Component Matching, GSER Zeilenga: Collective Attributes, Subentries, Transactions, Lang Tag/Ranges (RFC2596bis), … Weltman: Proxy Authz, Java LDAP Harrison: Intermediate Responses, LBURP

  13. Summary • LDAP Standardization is alive and well. • Most extension work being done on an “individual” basis. • May be difficult for vendors and deployers to determine which technical specifications are applicable. More applicabililty statements are needed.
