All Rights Reserved. + +Abstract + + The Connection-less Lightweight Directory Access Protocol (CLDAP) + technical specification, RFC 1798, was published in 1995 as a + Proposed Standard. This document discusses the reasons why the CLDAP + technical specification has not been furthered on the Standard Track. + This document recommends that RFC 1798 be moved to Historic status. + +1. Background + + Connection-less Lightweight Directory Access Protocol (CLDAP) + [RFC1798] was published in 1995 as a Proposed Standard. The protocol + was targeted at applications which require lookup of small amounts of + information held in the directory. The protocol avoids the overhead + of establishing (and closing) a connection and the session bind and + unbind operations needed in connection-oriented directory access + protocols. The CLDAP was designed to complement version 2 of the + Lightweight Directory Access Protocol (LDAPv2) [RFC1777], now + Historic [HISTORIC]. + + In the seven years since its publication, CLDAP has not become widely + deployed on the Internet. There are a number of probable reasons for + this: + + - Limited functionality: + + anonymous only, + + read only, + + small result sizes only, and + + + +Zeilenga Informational [Page 1] + +RFC 3352 CLDAP to Historic Status March 2003 + + + - Insufficient security capabilities: + + no integrity protection, + + no confidentiality protection + - Inadequate internationalization support; + - Insufficient extensibility; and + - Lack of multiple independently developed implementations. + + The CLDAP technical specification has normative references to + multiple obsolete technical specifications including X.501(88), + X.511(88), RFC 1487 (the predecessor to RFC 1777, the now Historic + LDAPv2 technical specification). Unless the technical specification + were to be updated, CLDAP cannot remain on the standards track + because of the Normative reference to a Historic RFC. + + The community recognized in the mid-1990s that CLDAP needed to be + updated. In response to this, the IETF chartered the LDAP Extensions + Working Group (LDAPext WG) in 1997 to undertake this update. The + LDAPext WG is concluding without producing an update to CLDAP. + Currently, there is no standardization effort to update CLDAP. + + It should be noted that the community still has interest in + developing a "connection-less" directory access protocol. However, + based on operational experience, has determined that further + experimentation is necessary to address outstanding technical issues. + In particular, security considerations associated with + "connection-less" services need to be addressed. + +2. Recommendation + + As there is no viable standardization effort to update CLDAP as + necessary to keep it on the standards track and the community + currently considers this an area requiring further experimentation, + RFC 1798 must be moved to Historic status. + + It is recommended that those interested in connection-less access to + X.500-based directory services experiment with [LDAPUDP] and other + alternatives which might become available. + +3. Security Considerations + + The security of the Internet will not be impacted by the retirement + of CLDAP. + +4.
