Lightweight Directory Access Protocol : Internationalized String Preparation

Overview

RFC 4518, “Lightweight Directory Access Protocol : Internationalized String Preparation”, is a Proposed Standard document published in June 2006 by K. Zeilenga. The canonical text is published by the RFC Editor.

Abstract

The previous Lightweight Directory Access Protocol (LDAP) technical specifications did not precisely define how character string matching is to be performed. This led to a number of usability and interoperability problems. This document defines string preparation algorithms for character-based matching rules defined for use in LDAP. [STANDARDS-TRACK]

Abstract as published in the RFC, via rfc-editor.org.
