INTERNET-DRAFT LDAP: Additional Matching Rules 5 June 2003

Abstract

This document provides a collection of matching rules for use with
the Lightweight Directory Access Protocol (LDAP). As these matching
rules are simple adaptations of matching rules specified for use with
the X.500 Directory, most are already in wide use.

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 [PCIM] [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.

Zeilenga draft-zeilenga-ldap-user-schema-mr-00 [Page 2]

INTERNET-DRAFT LDAP: Additional Matching Rules 5 June 2003 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. 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)

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 )

Zeilenga draft-zeilenga-ldap-user-schema-mr-00 [Page 3]

INTERNET-DRAFT LDAP: Additional Matching Rules 5 June 2003

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)

SYNTAX 1.3.6.1.4.1.1466.115.121.1.58 )

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.

( 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.

described in [RFC2252].

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. (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)

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

Zeilenga draft-zeilenga-ldap-user-schema-mr-00 [Page 6]

INTERNET-DRAFT LDAP: Additional Matching Rules 5 June 2003
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].
