1. Background and Intended Use
This document adapts additional X.500 Directory [X.500] matching
rules [X.520] for use with the Lightweight Directory Access Protocol
(LDAP) [RFC3377]. Most of these rules are widely used today on the
Internet, such as in support of the inetOrgPerson [RFC2798] and
Policy Core Information Model [RFC3703] LDAP schemas. The rules are
applicable to many other applications.
This document supersedes the informational matching rules
descriptions provided in RFC 2798 that are now provided in this
document. Specifically, section 2 of this document replaces section
9.3.3 of RFC 2798.
Schema definitions are provided using LDAP description formats
[RFC2252]. Definitions provided here are formatted (line wrapped)
for readability.
2. Matching Rules
2.1. booleanMatch
The booleanMatch rule compares for equality a asserted Boolean value
with an attribute value of BOOLEAN syntax. The rule returns TRUE if
and only if the values are the same, i.e., both are TRUE or both are
FALSE. (Source: X.520)
( 2.5.13.13 NAME 'booleanMatch'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 )
The BOOLEAN (1.3.6.1.4.1.1466.115.121.1.7) syntax is described in
[RFC2252].
2.2. caseExactMatch
The caseExactMatch rule compares for equality the asserted value with
an attribute value of DirectoryString syntax. The rule is identical
to the caseIgnoreMatch [RFC2252] rule except that case is not
ignored. (Source: X.520)
Zeilenga Standards Track [Page 2]
RFC 3698 LDAP: Additional Matching Rules February 2004
( 2.5.13.5 NAME 'caseExactMatch'
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 [RFC2252].
2.3. caseExactOrderingMatch
The caseExactOrderingMatch rule compares the collation order of the
asserted string with an attribute value of DirectoryString syntax.
The rule is identical to the caseIgnoreOrderingMatch [RFC2252] rule
except that letters are not folded. (Source: X.520)
( 2.5.13.6 NAME 'caseExactOrderingMatch'
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 [RFC2252].
2.4. caseExactSubstringsMatch
The caseExactSubstringsMatch rule determines whether the asserted
value(s) are substrings of an attribute value of DirectoryString
syntax. The rule is identical to the caseIgnoreSubstringsMatch
[RFC2252] rule except that case is not ignored. (Source: X.520)
( 2.5.13.7 NAME 'caseExactSubstringsMatch'
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 [RFC2252].
2.5. caseIgnoreListSubstringsMatch
The caseIgnoreListSubstringMatch rule compares the asserted substring
with an attribute value which is a sequence of DirectoryStrings, but
where the case (upper or lower) is not significant for comparison
purposes. The asserted value matches a stored value if and only if
the asserted value matches the string formed by concatenating the
strings of the stored value. This matching is done according to the
caseIgnoreSubstringsMatch [RFC2252] rule; however, none of the
initial, any, or final values of the asserted value are considered to
match a substring of the concatenated string which spans more than
one of the strings of the stored value. (Source: X.520)
( 2.5.13.12 NAME 'caseIgnoreListSubstringsMatch'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.58 )
Zeilenga Standards Track [Page 3]
RFC 3698 LDAP: Additional Matching Rules February 2004
The SubstringsAssertion (1.3.6.1.4.1.1466.115.121.1.58) syntax is
described in [RFC2252].
2.6. directoryStringFirstComponentMatch
The directoryStringFirstComponentMatch rule compares for equality the
asserted DirectoryString value with an attribute value of type
SEQUENCE whose first component is mandatory and of type
DirectoryString. The rule returns TRUE if and only if the attribute
value has a first component whose value matches the asserted
DirectoryString using the rules of caseIgnoreMatch [RFC2252]. A
value of the assertion syntax is derived from a value of the
attribute syntax by using the value of the first component of the
SEQUENCE. (Source: X.520)
( 2.5.13.31 NAME 'directoryStringFirstComponentMatch'
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 [RFC2252].
2.7. integerOrderingMatch
The integerOrderingMatch rule compares the ordering of the asserted
integer with an attribute value of INTEGER syntax. The rule returns
True if the attribute value is less than the asserted value. (Source:
X.520)
( 2.5.13.15 NAME 'integerOrderingMatch'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 )
The INTEGER (1.3.6.1.4.1.1466.115.121.1.27) syntax is described in
[RFC2252].
2.8. keywordMatch
The keywordMatch rule compares the asserted string with keywords in
an attribute value of DirectoryString syntax. The rule returns TRUE
if and only if the asserted value matches any keyword in the
attribute value. The identification of keywords in an attribute
value and of the exactness of match are both implementation specific.
(Source: X.520)
( 2.5.13.33 NAME 'keywordMatch'
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 [RFC2252].
Zeilenga Standards Track [Page 4]
RFC 3698 LDAP: Additional Matching Rules February 2004
2.9. numericStringOrderingMatch
The numericStringOrderingMatch rule compares the collation order of
the asserted string with an attribute value of NumericString syntax.
The rule is identical to the caseIgnoreOrderingMatch [RFC2252] rule
except that all space characters are skipped during comparison (case
is irrelevant as characters are numeric). (Source: X.520)
( 2.5.13.9 NAME 'numericStringOrderingMatch'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.36 )
The NumericString (1.3.6.1.4.1.1466.115.121.1.36) syntax is described
in [RFC2252].
2.10. octetStringOrderingMatch
The octetStringOrderingMatch rule compares the collation order of the
asserted octet string with an attribute value of OCTET STRING syntax.
The rule compares octet strings from first octet to last octet, and
from the most significant bit to the least significant bit within the
octet. The first occurrence of a different bit determines the
ordering of the strings. A zero bit precedes a one bit. If the
strings are identical but contain different numbers of octets, the
shorter string precedes the longer string. (Source: X.520)
( 2.5.13.18 NAME 'octetStringOrderingMatch'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 )
The OCTET STRING (1.3.6.1.4.1.1466.115.121.1.40) syntax is described
in [RFC2252].
2.11. storedPrefixMatch
The storedPrefixMatch rule determines whether an attribute value,
whose syntax is DirectoryString is a prefix (i.e., initial substring)
of the asserted value, without regard to the case (upper or lower) of
the strings. The rule returns TRUE if and only if the attribute
value is an initial substring of the asserted value with
corresponding characters identical except possibly with regard to
case. (Source: X.520)
( 2.5.13.41 NAME 'storedPrefixMatch'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )
Zeilenga Standards Track [Page 5]
RFC 3698 LDAP: Additional Matching Rules February 2004
Note: This rule can be used, for example, to compare values in the
Directory which are telephone area codes with a purported value
which is a telephone number.
The DirectoryString (1.3.6.1.4.1.1466.115.121.1.15) syntax is
described in [RFC2252].
2.12. wordMatch
The wordMatch rule compares the asserted string with words in an
attribute value of DirectoryString syntax. The rule returns TRUE if
and only if the asserted word matches any word in the attribute
value. Individual word matching is as for the caseIgnoreMatch
[RFC2252] matching rule. The precise definition of a "word" is
implementation specific. (Source: X.520)
( 2.5.13.32 NAME 'wordMatch'
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 [RFC2252].
3. Security Considerations
General LDAP security considerations [RFC3377] is applicable to the
use of this schema. Additional considerations are noted above where
appropriate.

ASN.1 Module Definition for the
LDAP and X.500 Component Matching Rules
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This document updates the specification of the component matching
rules for Lightweight Directory Access Protocol (LDAP) and X.500
directories (RFC3687) by collecting the Abstract Syntax Notation One
(ASN.1) definitions of the component matching rules into an
appropriately identified ASN.1 module so that other specifications
may reference the component matching rule definitions from within
their own ASN.1 modules.
1. Introduction
The structure or data type of data held in an attribute of a
Lightweight Directory Access Protocol (LDAP) [LDAP] or X.500 [X500]
directory is described by the attribute's syntax. Attribute syntaxes
range from simple data types, such as text string, integer, or
boolean, to complex data types, for example, the syntaxes of the
directory schema operational attributes. RFC 3687 [CMR] defines a
generic way of matching user selected components in a directory
attribute value of any arbitrarily complex attribute syntax.
This document updates RFC 3687 by collecting the Abstract Syntax
Notation One (ASN.1) [ASN1] definitions of RFC 3687 into an
appropriately identified ASN.1 module so that other specifications
may reference these definitions from within their own ASN.1 modules.
