Lightweight Directory Access Protocol : Syntaxes and Matching Rules
RFC 4517, “Lightweight Directory Access Protocol : Syntaxes and Matching Rules”, is a Proposed Standard document published in June 2006 by S. Legg. It updates RFC 3698. It obsoletes RFC 2252, RFC 2256. The canonical text is published by the RFC Editor.
Abstract
Each attribute stored in a Lightweight Directory Access Protocol (LDAP) directory, whose values may be transferred in the LDAP protocol, has a defined syntax that constrains the structure and format of its values. The comparison semantics for values of a syntax are not part of the syntax definition but are instead provided through separately defined matching rules. Matching rules specify an argument, an assertion value, which also has a defined syntax. This document defines a base set of syntaxes and matching rules for use in defining attributes for LDAP directories. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
