Network Working Group A. Pauzies Internet-Draft LINAGORA Expires: October 22, 2004 April 23, 2004 LDAP: Additional Matching Rules draft-pauzies-ldap-schema-nonascii-mr-00 Status of this Memo By submitting this Internet-Draft, I certify that any applicable patent or other IPR claims of which I am aware have been disclosed, and any of which I become aware will be disclosed, in accordance with RFC 3668. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." The list of current Internet-Drafts can be accessed at http:// www.ietf.org/ietf/1id-abstracts.txt. The list of Internet-Draft Shadow Directories can be accessed at http://www.ietf.org/shadow.html.

Abstract This document provides a collection of matching rules for use with the Lightweight Directory Access Protocol (LDAP). Thoses matching rules are simple adaptations of existing LDAP matching rules allowing a more flexible match on non-ASCII strings.

Background and Intended Use When using thoses rules, non-ASCII characters such as letters with accents are converted (when UTF-8 compatibility conversion is possible RFC 2044 [RFC2044]) to ASCII characters (same letter without accent) before the match. Pauzies Expires October 22, 2004 [Page 3] Internet-Draft LDAP: Additional Matching Rules April 2004 2. Matching Rules 2.1 caseIgnoreNonasciiMatch The caseIgnoreNonasciiMatch rule compares for equality the asserted value with an attribute value of DirectoryString syntax. The rule is identical to the caseIgnoreMatch RFC 2252 [RFC2252] rule except that non-ASCII characters are matched like their ASCII equivalent. ( 1.3.6.1.4.1.10943.10.4.1 NAME 'caseIgnoreNonasciiMatch' SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) The DirectoryString (1.3.6.1.4.1.1466.115.121.1.15) syntax is described in RFC 2252 [RFC2252]. 2.2 caseIgnoreNonasciiOrderingMatch The caseIgnoreNonasciiOrderingMatch rule compares the collation order of the asserted string with an attribute value of DirectoryString syntax. The rule is identical to the caseIgnoreOrderingMatch RFC 2252 [RFC2252] rule except that non-ASCII characters are matched like their ASCII equivalent ( 1.3.6.1.4.1.10943.10.4.2 NAME 'caseIgnoreNonasciiOrderingMatch' SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) 2.3 caseIgnoreNonasciiSubstringMatch The caseIgnoreNonasciiSubstringsMatch rule determines whether the asserted value(s) are substrings of an attribute value of DirectoryString syntax. The rule is identical to the caseIgnoreSubstringsMatch RFC 2252 [RFC2252] rule except that non-ASCII characters are matched like their ASCII equivalent. ( 1.3.6.1.4.1.10943.10.4.3 NAME 'caseIgnoreNonasciiSubstringsMatch' SYNTAX 1.3.6.1.4.1.1466.115.121.1.58 ) The SubstringsAssertion (1.3.6.1.4.1.1466.115.121.1.58) syntax is described in RFC 2252 [RFC2252].
