INTERNET-DRAFT LDAP: Syntaxes and Matching Rules June 23, 2005
|
||
|
||
|
||
Each attribute stored in a Lightweight Directory Access Protocol
|
||
(LDAP) directory, and whose values may be transfered in the LDAP
|
||
protocol, has a defined syntax which 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.

1. Introduction
|
||
|
||
Each attribute stored in a Lightweight Directory Access Protocol
|
||
(LDAP) directory [ROADMAP], and whose values may be transfered in the
|
||
LDAP protocol [PROT], has a defined syntax (i.e., data type) which
|
||
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.
|
||
|
||
Readers are advised to familiarize themselves with the Directory
|
||
Information Models [MODELS] before reading the rest of this document.
|
||
Section 3 provides definitions for the base set of LDAP syntaxes.
|
||
Section 4 provides definitions for the base set of matching rules for
|
||
LDAP.
|
||
|
||
This document is a integral part of the LDAP technical specification
|
||
[ROADMAP] which obsoletes the previously defined LDAP technical
|
||
specification [RFC3377] in its entirety.
|
||
|
||
Sections 4, 5 and 7 of RFC 2252 [RFC2252] are obsoleted by [MODELS].
|
||
The remainder of RFC 2252 is obsoleted by this document. Sections 6
|
||
and 8 of RFC 2256 [RFC2256] are obsoleted by this document. The
|
||
remainder of RFC 2256 is obsoleted by [SCHEMA] and [MODELS]. All but
|
||
Section 2.11 of RFC 3698 [RFC3698] is obsoleted by this document.
|
||
|
||
A number of schema elements which were included in the previous
|
||
revision of the LDAP technical specification are not included in this
|
||
revision of LDAP. Public Key Infrastructure schema elements are now
|
||
specified in [LDAP-PKI]. Unless reintroduced in future technical
|
||
specifications, the remainder are to be considered Historic.
|
||
|
||
The changes with respect to RFC 2252 are described in Appendix B of
|
||
this document.
|
||
|
||
2. Conventions
|
||
|
||
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
|
||
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
|
||
document are to be interpreted as described in BCP 14, RFC 2119
|
||
[KEYWORD].
|
||
|
||
Syntax definitions are written according to the <SyntaxDescription>
|
||
ABNF [ABNF] rule specified in [MODELS], and matching rule definitions
|
||
are written according to the <MatchingRuleDescription> ABNF rule
|
||
specified in [MODELS], except that the syntax and matching rule
|
||
definitions provided in this document are line-wrapped for
|
||
readability. When such definitions are transfered as attribute
|
||
values in the LDAP protocol (e.g., as values of the ldapSyntaxes and
|
||
matchingRules attributes [MODELS] respectively) then those values
|
||
would not contain line breaks.
|
||
|
||
3. Syntaxes
|
||
|
||
|
||
|
||
|
||
Legg Expires 23 December 2005 [Page 5]
|
||
|
||
INTERNET-DRAFT LDAP: Syntaxes and Matching Rules June 23, 2005
|
||
|
||
|
||
Syntax definitions constrain the structure of attribute values stored
|
||
in an LDAP directory, and determine the representation of attribute
|
||
and assertion values transfered in the LDAP protocol.
|
||
|
||
Syntaxes that are required for directory operation, or that are in
|
||
common use, are specified in this section. Servers SHOULD recognize
|
||
all the syntaxes listed in this document, but are not required to
|
||
otherwise support them, and MAY recognise or support other syntaxes.
|
||
However, the definition of additional arbitrary syntaxes is
|
||
discouraged since it will hinder interoperability. Client and server
|
||
implementations typically do not have the ability to dynamically
|
||
recognize new syntaxes.
|
||
|
||
3.1. General Considerations
|
||
|
||
The description of each syntax specifies how attribute or assertion
|
||
values conforming to the syntax are to be represented when transfered
|
||
in the LDAP protocol [PROT]. This representation is referred to as
|
||
the LDAP-specific encoding to distinguish it from other methods of
|
||
encoding attribute values (e.g., the Basic Encoding Rules (BER)
|
||
encoding [BER] used by X.500 [X.500] directories).
|
||
|
||
The LDAP-specific encoding of a given attribute syntax always
|
||
produces octet-aligned values. To the greatest extent possible,
|
||
encoding rules for LDAP syntaxes should produce character strings
|
||
that can be displayed with little or no translation by clients
|
||
implementing LDAP. However, clients MUST NOT assume that the
|
||
LDAP-specific encoding of a value of an unrecognized syntax is a
|
||
human-readable character string. There are a few cases (e.g., the
|
||
JPEG syntax) when it is not reasonable to produce a human-readable
|
||
representation.
|
||
|
||
Each LDAP syntax is uniquely identified with an object identifier
|
||
[ASN.1] represented in the dotted-decimal format (short descriptive
|
||
names are not defined for syntaxes). These object identifiers are
|
||
not intended to be displayed to users. The object identifiers for
|
||
the syntaxes defined in this document are summarized in Appendix A.
|
||
|
||
A suggested minimum upper bound on the number of characters in an
|
||
attribute value with a string-based syntax, or the number of octets
|
||
in a value for all other syntaxes, MAY be indicated by appending the
|
||
bound inside of curly braces following the syntax's OBJECT IDENTIFIER
|
||
in an attribute type definition (see the <noidlen> rule in [MODELS]).
|
||
Such a bound is not considered part of the syntax identifier.
|
||
|
||
For example, "1.3.6.1.4.1.1466.115.121.1.15{64}" in an attribute
|
||
definition suggests that the directory server will allow a value of
|
||
the attribute to be up to 64 characters long, although it may allow
|
||
|
||
|
||
|

|
||
|
||
|
||
longer character strings. Note that a single character of the
|
||
Directory String syntax can be encoded in more than one octet since
|
||
UTF-8 [UTF8] is a variable-length encoding. Therefore a 64 character
|
||
string may be more than 64 octets in length.
|
||
|
||
3.2. Common Definitions
|
||
|
||
The following ABNF rules are used in a number of the syntax
|
||
definitions in Section 3.3.
|
||
|
||
PrintableCharacter = ALPHA / DIGIT / SQUOTE / LPAREN / RPAREN /
|
||
PLUS / COMMA / HYPHEN / DOT / EQUALS /
|
||
SLASH / COLON / QUESTION / SPACE
|
||
PrintableString = 1*PrintableCharacter
|
||
IA5String = *(%x00-7F)
|
||
SLASH = %x2F ; forward slash ("/")
|
||
COLON = %x3A ; colon (":")
|
||
QUESTION = %x3F ; question mark ("?")
|
||
|
||
The <ALPHA>, <DIGIT>, <SQUOTE>, <LPAREN>, <RPAREN>, <PLUS>, <COMMA>,
|
||
<HYPHEN>, <DOT>, <EQUALS> and <SPACE> rules are defined in [MODELS].
|
||
|
||
3.3. Syntax Definitions
|
||
|
||
3.3.1. Attribute Type Description
|
||
|
||
A value of the Attribute Type Description syntax is the definition of
|
||
an attribute type. The LDAP-specific encoding of a value of this
|
||
syntax is defined by the <AttributeTypeDescription> rule in [MODELS].
|
||
|
||
For example, the following definition of the createTimestamp
|
||
attribute type from [MODELS] is also a value of the Attribute Type
|
||
Description syntax (note: line breaks have been added for
|
||
readability - they are not part of the value when transfered in
|
||
protocol).
|
||
|
||
( 2.5.18.1 NAME 'createTimestamp'
|
||
EQUALITY generalizedTimeMatch
|
||
ORDERING generalizedTimeOrderingMatch
|
||
SYNTAX 1.3.6.1.4.1.1466.115.121.1.24
|
||
SINGLE-VALUE NO-USER-MODIFICATION
|
||
USAGE directoryOperation )
|
||
|
||
The LDAP definition for the Attribute Type Description syntax is:
|
||
|
||
( 1.3.6.1.4.1.1466.115.121.1.3 DESC 'Attribute Type Description' )
|
||
|
||
This syntax corresponds to the AttributeTypeDescription ASN.1 type
|
||
|
||
|
||

||
|
||
|
||
from [X.501].
|
||
|
||
3.3.2. Bit String
|
||
|
||
A value of the Bit String syntax is a sequence of binary digits. The
|
||
LDAP-specific encoding of a value of this syntax is defined by the
|
||
following ABNF:
|
||
|
||
BitString = SQUOTE *binary-digit SQUOTE "B"
|
||
binary-digit = "0" / "1"
|
||
|
||
The <SQUOTE> rule is defined in [MODELS].
|
||
|
||
Example:
|
||
'0101111101'B
|
||
|
||
The LDAP definition for the Bit String syntax is:
|
||
|
||
( 1.3.6.1.4.1.1466.115.121.1.6 DESC 'Bit String' )
|
||
|
||
This syntax corresponds to the BIT STRING ASN.1 type from [ASN.1].
|
||
|
||
3.3.3. Boolean
|
||
|
||
A value of the Boolean syntax is one of the Boolean values, true or

|
||
|
||
|
||
A value of the Directory String syntax is a string of one or more
|
||
arbitrary characters from the Universal Character Set (UCS) [UCS]. A
|
||
zero length character string is not permitted. The LDAP-specific
|
||
encoding of a value of this syntax is the UTF-8 encoding [UTF8] of
|
||
the character string. Such encodings conform to the following ABNF:
|
||
|
||
DirectoryString = 1*UTF8
|
||
|
||
The <UTF8> rule is defined in [MODELS].
|
||
|
||
Example:
|
||
This is a value of Directory String containing #!%#@.
|
||
|
||
Servers and clients MUST be prepared to receive arbitrary UCS code
|
||
points, including code points outside the range of printable ASCII
|
||
and code points not presently assigned to any character.
|
||
|
||
Attribute type definitions using the Directory String syntax should
|
||
not restrict the format of Directory String values, e.g., by
|
||
requiring that the character string conforms to specific patterns
|
||
described by ABNF. A new syntax should be defined in such cases.
|
||
|
||
The LDAP definition for the Directory String syntax is:
|
||
|
||
( 1.3.6.1.4.1.1466.115.121.1.15 DESC 'Directory String' )
|
||
|
||
This syntax corresponds to the DirectoryString parameterized ASN.1
|
||
type from [X.520].
|
||
|
||
The DirectoryString ASN.1 type allows a choice between the
|
||
TeletexString, PrintableString or UniversalString ASN.1 types from
|
||
[ASN.1]. However, note that the chosen alternative is not indicated
|
||
in the LDAP-specific encoding of a Directory String value.
|
||
|
||
Implementations which convert Directory String values from the
|
||
LDAP-specific encoding to the BER encoding used by X.500 must choose
|
||
an alternative that permits the particular characters in the string,
|
||
and must convert the characters from the UTF-8 encoding into the
|
||
character encoding of the chosen alternative. When converting
|
||
Directory String values from the BER encoding to the LDAP-specific
|
||
encoding the characters must be converted from the character encoding
|
||
of the chosen alternative into the UTF-8 encoding. These conversions
|
||
SHOULD be done in a manner consistent with the Transcode step of the
|
||
string preparation algorithms [PREP] for LDAP.

|
||
of a DIT (Directory Information Tree) content rule. The
|
||
LDAP-specific encoding of a value of this syntax is defined by the

<DITContentRuleDescription> rule in [MODELS].
|
||
|
||
Example:
|
||
( 2.5.6.4 DESC 'content rule for organization'
|
||

|
||
|
||
Note: a line break has been added for readability - it is not part

The LDAP definition for the DIT Content Rule Description syntax is:
|
||
|
||
( 1.3.6.1.4.1.1466.115.121.1.16
|

from [X.501].
|
||
|
||
3.3.8. DIT Structure Rule Description
|
||
|
||
A value of the DIT Structure Rule Description syntax is the

value of this syntax is defined by the <DITStructureRuleDescription>
|
||
rule in [MODELS].
|
||
|
||
Example:
|
||
( 2 DESC 'organization structure rule' FORM 2.5.15.3 )
|

from [X.501].
|
||
|
||
3.3.9. DN
|
||
|
||
A value of the DN syntax is the (purported) distinguished name (DN)
|

syntax is defined by the <distinguishedName> rule from the string
|
||
representation of distinguished names [LDAPDN].
|
||
|
||
Examples (from [LDAPDN]):

( 1.3.6.1.4.1.1466.115.121.1.12 DESC 'DN' )
|
||
|
||
The DN syntax corresponds to the DistinguishedName ASN.1 type from
|
||
[X.501]. Note that a BER encoded distinguished name (as used by
|
||
X.500) re-encoded into the LDAP-specific encoding is not necessarily
|
||
reversible to the original BER encoding since the chosen string type
|
||
in any DirectoryString components of the distinguished name is not

(see Section 3.3.6).
|

||
A value of the Enhanced Guide syntax suggests criteria, which consist
|

of combinations of attribute types and filter operators, to be used
|
||
in constructing filters to search for entries of particular object
|
||
classes. The Enhanced Guide syntax improves upon the Guide syntax by
|
||
allowing the recommended depth of the search to be specified.
|
||
|
||
The LDAP-specific encoding of a value of this syntax is defined by
|
||
the following ABNF:

The above ABNF allows character strings which do not represent valid

dates (in the Gregorian calendar) and/or valid times (e.g., February
|
||

|
||
The time value represents coordinated universal time (equivalent to
|
||
Greenwich Mean Time) if the "Z" form of <g-time-zone> is used,
|
||
otherwise the value represents a local time in the time zone
|
||
indicated by <g-differential>. In the latter case, coordinated

universal time can be calculated by subtracting the differential from
|
||
the local time. The "Z" form of <g-time-zone> SHOULD be used in
|
||
preference to <g-differential>.
|
||
|
||
If <minute> is omitted then <fraction> represents a fraction of an
|

||
the matchValue of a MatchingRuleAssertion [PROT]. Each substring is
|
||
a string of one or more arbitrary characters from the Universal
|
||
Character Set (UCS) [UCS]. A zero length substring is not permitted.
|
||
|
||
The LDAP-specific encoding of a value of this syntax is defined by
|
||
the following ABNF:
|
||
|
||
SubstringAssertion = [ initial ] any [ final ]
|
||
|
||
initial = substring

|
||
the substring, are escaped by a "\" character followed by the two
|
||
hexadecimal digit code for the character.
|
||
|
||
The Substring Assertion syntax is used only as the syntax of

The above ABNF allows character strings which do not represent valid
|
||
dates (in the Gregorian calendar) and/or valid times. Such character
|
||
strings SHOULD be considered invalid for this syntax.
|
||
|
||
The time value represents coordinated universal time if the "Z" form
|
||
of <u-time-zone> is used, otherwise the value represents a local
|
||
time. In the latter case, if <u-differential> is provided then
|
||
coordinated universal time can be calculated by subtracting the
|
||
differential from the local time. The <u-time-zone> SHOULD be
|
||
present in time values and the "Z" form of <u-time-zone> SHOULD be
|
||
used in preference to <u-differential>.

4. Matching Rules
|
||
|
||
Matching rules are used by directory implementations to compare
|
||
attribute values against assertion values when performing Search and
|
||
Compare operations [PROT]. They are also used when comparing a
|
||
purported distinguished name [MODELS] with the name of an entry.
|
||
When modifying entries, matching rules are used to identify values to
|
||
be deleted and to prevent an attribute from containing two equal
|
||
values.
|
||
|
||
Matching rules that are required for directory operation, or that are
|
||
in common use, are specified in this section.
|
||
|
||
4.1. General Considerations
|
||
|
||
A matching rule is applied to attribute values through an
|
||
AttributeValueAssertion or MatchingRuleAssertion [PROT]. The
|
||
conditions under which an AttributeValueAssertion or
|
||
MatchingRuleAssertion evaluates to Undefined are specified elsewhere
|
||
[PROT]. If an assertion is not Undefined then the result of the
|
||
assertion is the result of applying the selected matching rule. A
|
||
matching rule evaluates to TRUE, and in some cases Undefined, as
|
||
specified in the description of the matching rule, otherwise it
|
||
evaluates to FALSE.
|
||
|
||
Each assertion contains an assertion value. The definition of each

INTERNET-DRAFT LDAP: Syntaxes and Matching Rules June 23, 2005
|
||
|
||
|
||
matching rule specifies the syntax for the assertion value. The
|
||
syntax of the assertion value is typically, but not necessarily, the
|
||
same as the syntax of the attribute values to which the matching rule
|
||
may be applied. Note that an AssertionValue in a SubstringFilter
|
||
[PROT] conforms to the assertion syntax of the equality matching rule
|
||
for the attribute type rather than the assertion syntax of the
|
||
substrings matching rule for the attribute type. Conceptually, the
|
||
entire SubstringFilter is converted into an assertion value of the
|
||
substrings matching rule prior to applying the rule.
|
||
|
||
The definition of each matching rule indicates the attribute syntaxes
|
||
to which the rule may be applied, by specifying conditions the
|
||
corresponding ASN.1 type of a candidate attribute syntax must
|
||
satisfy. These conditions are also satisfied if the corresponding
|
||
ASN.1 type is a tagged or constrained derivative of the ASN.1 type
|
||
explicitly mentioned in the rule description (i.e., ASN.1 tags and
|
||
constraints are ignored in checking applicability), or an alternative
|
||
reference notation for the explicitly mentioned type. Each rule
|
||
description lists as examples of applicable attribute syntaxes, the
|
||
complete list of the syntaxes defined in this document to which the
|
||
matching rule applies. A matching rule may be applicable to
|
||
additional syntaxes defined in other documents if those syntaxes
|
||
satisfy the conditions on the corresponding ASN.1 type.
|
||
|
||
The description of each matching rule indicates whether the rule is
|
||
suitable for use as the equality matching rule (EQUALITY), ordering
|
||
matching rule (ORDERING) or substrings matching rule (SUBSTR) in an
|
||
attribute type definition [MODELS].
|
||
|
||
Each matching rule is uniquely identified with an object identifier.
|
||
The definition of a matching rule should not be subsequently changed.
|
||
If a change is desirable then a new matching rule with a different
|
||
object identifier should be defined instead.
|
||
|
||
Servers MAY implement the wordMatch and keywordMatch matching rules,
|
||
but SHOULD implement the other matching rules in Section 4.2.
|
||
Servers MAY implement additional matching rules.
|
||
|
||
Servers which implement the extensibleMatch filter SHOULD allow the
|
||
matching rules listed in Section 4.2 to be used in the
|
||
extensibleMatch filter and SHOULD allow matching rules to be used
|
||
with all attribute types known to the server, where the assertion
|
||
syntax of the matching rule is the same as the value syntax of the
|
||
attribute.
|
||
|
||
Servers MUST publish in the matchingRules attribute, the definitions
|
||
of matching rules referenced by values of the attributeTypes and
|
||
matchingRuleUse attributes in the same subschema entry. Other

|
||
unreferenced matching rules MAY be published in the matchingRules
|
||
attribute.
|
||
|
||
If the server supports the extensibleMatch filter, then the server
|
||
MAY use the matchingRuleUse attribute to indicate the applicability
|
||
(in an extensibleMatch filter) of selected matching rules to
|
||
nominated attribute types.
|
||
|
||
4.2. Matching Rule Definitions
|
||
|
||
Nominated character strings in assertion and attribute values are
|
||
prepared according to the string preparation algorithms [PREP] for
|
||
LDAP when evaluating the following matching rules:
|
||
|
||
numericStringMatch,
|
||
numericStringSubstringsMatch,
|
||
caseExactMatch,
|
||
caseExactOrderingMatch,
|
||
caseExactSubstringsMatch,
|
||
caseExactIA5Match,
|
||
caseIgnoreIA5Match,
|
||
caseIgnoreIA5SubstringsMatch,
|
||
caseIgnoreListMatch,
|
||
caseIgnoreListSubstringsMatch,
|
||
caseIgnoreMatch,
|
||
caseIgnoreOrderingMatch,
|
||
caseIgnoreSubstringsMatch,
|
||
directoryStringFirstComponentMatch,
|
||
telephoneNumberMatch,
|
||
telephoneNumberSubstringsMatch and
|
||
wordMatch.
|
||
|
||
The Transcode, Normalize, Prohibit and Check bidi steps are the same
|
||
for each of the matching rules. However, the Map and Insignificant
|
||
Character Handling steps depends on the specific rule, as detailed in
|
||
the description of these matching rules in the sections that follow.
|
||
|
||
4.2.1. bitStringMatch
|
||
|
||
The bitStringMatch rule compares an assertion value of the Bit String
|
||
syntax to an attribute value of a syntax (e.g., the Bit String
|
||
syntax) whose corresponding ASN.1 type is BIT STRING.
|
||
|
||
If the corresponding ASN.1 type of the attribute syntax does not have
|
||
a named bit list [ASN.1] (which is the case for the Bit String
|
||
syntax) then the rule evaluates to TRUE if and only if the attribute
|
||
value has the same number of bits as the assertion value and the bits
|
||
match on a bitwise basis.

|
||
|
||
|
||
If the corresponding ASN.1 type does have a named bit list then
|
||
bitStringMatch operates as above except that trailing zero bits in
|
||
the attribute and assertion values are treated as absent.
|
||
|
||
The LDAP definition for the bitStringMatch rule is:

|
||
|
||
The bitStringMatch rule is an equality matching rule.
|
||
|
||
4.2.2. booleanMatch
|
||
|
||
The booleanMatch rule compares an assertion value of the Boolean
|
||
syntax to an attribute value of a syntax (e.g., the Boolean syntax)
|
||
whose corresponding ASN.1 type is BOOLEAN.
|
||
|
||
The rule evaluates to TRUE if and only if the attribute value and the
|
||
assertion value are both TRUE or both FALSE.

||
4.2.3. caseExactIA5Match
|
||
|
||
The caseExactIA5Match rule compares an assertion value of the IA5
|
||
String syntax to an attribute value of a syntax (e.g the IA5 String
|
||
syntax) whose corresponding ASN.1 type is IA5String.
|
||
|
||
The rule evaluates to TRUE if and only if the prepared attribute
|
||
value character string and the prepared assertion value character
|
||
string have the same number of characters and corresponding
|
||
characters have the same code point.
|
||
|
||
In preparing the attribute value and assertion value for comparison,
|
||
characters are not case folded in the Map preparation step, and only
|
||
Insignificant Space Handling is applied in the Insignificant

alternative string types of DirectoryString, e.g., PrintableString
|
||
(the other alternatives do not correspond to any syntax defined in

one of its alternative string types.
|
||
|
||
The rule evaluates to TRUE if, and only if, in the code point
|
||
collation order, the prepared attribute value character string
|
||
appears earlier than the prepared assertion value character string,
|
||
i.e., the attribute value is "less than" the assertion value.

4.2.15. distinguishedNameMatch
|

|
||
The distinguishedNameMatch rule compares an assertion value of the DN
|

syntax to an attribute value of a syntax (e.g., the DN syntax) whose
|

corresponding ASN.1 type is DistinguishedName.
|
||
|
||
The rule evaluates to TRUE if and only if the attribute value and the
|
||
assertion value have the same number of relative distinguished names
|
||
and corresponding relative distinguished names (by position) are the
|
||
same. A relative distinguished name (RDN) of the assertion value is
|
||
the same as an RDN of the attribute value if and only if they have
|
||
the same number of attribute value assertions and each attribute
|
||
value assertion (AVA) of the first RDN is the same as the AVA of the
|
||
second RDN with the same attribute type. The order of the AVAs is
|
||
not significant. Also note that a particular attribute type may
|
||
appear in at most one AVA in an RDN. Two AVAs with the same
|
||
attribute type are the same if their values are equal according to
|
||
the equality matching rule of the attribute type. If one or more of
|
||
the AVA comparisons evaluate to Undefined and the remaining AVA
|
||
comparisons return TRUE then the distinguishedNameMatch rule
|
||
evaluates to Undefined.

||
The rule evaluates to TRUE if and only if the attribute value

|
||
then the number of minutes or seconds (respectively) is assumed to be

syntaxes to be reconstructed, e.g., a transformation from a
|
||
Distinguished Encoding Rules (DER) [BER] encoding to an LDAP-specific
|
||
encoding and back to a DER encoding may not reproduce the original
|
||
DER encoding. Therefore LDAP-specific encodings should not be used
|
||
where reversibility to DER is needed, e.g., for the verification of
|
||
digital signatures. Instead, DER or a DER-reversible encoding should
|
||
be used.
|
||
|
||
When interpreting security-sensitive fields, and in particular fields
|
||
used to grant or deny access, implementations MUST ensure that any
|
||
matching rule comparisons are done on the underlying abstract value,
|
||
regardless of the particular encoding used.

|
||
Appendix B. Changes from RFC 2252
|
||
|
||
This annex lists the significant differences between this
|
||
specification and RFC 2252.
|
||
|
||
This annex is provided for informational purposes only. It is not a
|
||
normative part of this specification.
|
||
|
||
1. The IESG Note has been removed.
|
||
|
||
2. The major part of Sections 4, 5 and 7 has been moved to [MODELS]
|
||
and revised. Changes to the parts of these sections moved to
|
||
[MODELS] are detailed in [MODELS].
|
||
|
||
3. BNF descriptions of syntax formats have been replaced by ABNF
|
||
[ABNF] specifications.
|
||
|
||
4. The ambiguous statement in RFC 2252, Section 4.3 regarding the
|
||
use of a backslash quoting mechanism to escape separator symbols
|
||
has been removed. The escaping mechanism is now explicitly
|
||
represented in the ABNF for the syntaxes where this provision
|
||
applies.
|
||
|
||
5. The description of each of the LDAP syntaxes has been expanded so
|
||
that they are less dependent on knowledge of X.500 for
|
||
interpretation.
|
||
|
||
6. The relationship of LDAP syntaxes to corresponding ASN.1 type
|
||
definitions has been made explicit.
|
||
|
||
7. The set of characters allowed in a <PrintableString> (formerly
|
||
<printablestring>) has been corrected to align with the
|
||
PrintableString ASN.1 type in [ASN.1]. Specifically, the double
|
||
quote character has been removed and the single quote character
|
||
and equals sign have been added.
|
||
|
||
8. Values of the Directory String, Printable String and Telephone
|
||
Number syntaxes are now required to have at least one character.
|
||
|
||
9. The <DITContentRuleDescription>, <NameFormDescription> and
|
||
<DITStructureRuleDescription> rules have been moved to [MODELS].
|
||
|
||
10. The corresponding ASN.1 type for the Other Mailbox syntax has
|
||
been incorporated from RFC 1274.
|
||
|
||
11. A corresponding ASN.1 type for the LDAP Syntax Description syntax
|
||
has been invented.

||

|
||
|
||
INTERNET-DRAFT LDAP: Syntaxes and Matching Rules June 23, 2005
|
||
|
||
|
||
12. The Binary syntax has been removed because it was not adequately
|
||
specified, implementations with different incompatible
|
||
interpretations exist, and it was confused with the ;binary
|
||
transfer encoding.
|
||
|
||
13. All discussion of transfer options, including the ";binary"
|
||
option, has been removed. All imperatives regarding binary
|
||
transfer of values have been removed.
|
||
|
||
14. The Delivery Method, Enhanced Guide, Guide, Octet String, Teletex
|
||
Terminal Identifier and Telex Number syntaxes from RFC 2256 have
|
||
been incorporated.
|
||
|
||
15. The <criteria> rule for the Enhanced Guide and Guide syntaxes has
|
||
been extended to accommodate empty "and" and "or" expressions.
|
||
|
||
16. An encoding for the <ttx-value> rule in the Teletex Terminal
|
||
Identifier syntax has been defined.
|
||
|
||
17. The PKI-related syntaxes (Certificate, Certificate List and
|
||
Certificate Pair) have been removed. They are reintroduced in
|
||
[LDAP-PKI] (as is the Supported Algorithm syntax from RFC 2256).
|
||
|
||
18. The MHS OR Address syntax has been removed since its
|
||
specification (in RFC 2156) is not at draft standard maturity.
|
||
|
||
19. The DL Submit Permission syntax has been removed as it depends on
|
||
the MHS OR Address syntax.
|
||
|
||
20. The Presentation Address syntax has been removed since its
|
||
specification (in RFC 1278) is not at draft standard maturity.
|
||
|
||
21. The ACI Item, Access Point, Audio, Data Quality, DSA Quality, DSE
|
||
Type, LDAP Schema Description, Master And Shadow Access Points,
|
||
Modify Rights, Protocol Information, Subtree Specification,
|
||
Supplier Information, Supplier Or Consumer and Supplier And
|
||
Consumer syntaxes have been removed. These syntaxes are
|
||
referenced in RFC 2252, but not defined.
|
||
|
||
22. The LDAP Schema Definition syntax (defined in RFC 2927) and the
|
||
Mail Preference syntax have been removed on the grounds that they
|
||
are out of scope for the core specification.
|
||
|
||
23. The description of each of the matching rules has been expanded
|
||
so that they are less dependent on knowledge of X.500 for
|
||
interpretation.
|
||
|
||
24. The caseIgnoreIA5SubstringsMatch matching rule from RFC 2798 has
|
||
|
||
|
||
|
||
Legg Expires 23 December 2005 [Page 49]
|
||
|
||
INTERNET-DRAFT LDAP: Syntaxes and Matching Rules June 23, 2005
|
||
|
||
|
||
been added.
|
||
|
||
25. The caseIgnoreListSubstringsMatch, caseIgnoreOrderingMatch and
|
||
caseIgnoreSubstringsMatch matching rules have been added to the
|
||
list of matching rules for which the provisions for handling
|
||
leading, trailing and multiple adjoining whitespace characters
|
||
apply (now through string preparation). This is consistent with
|
||
the definitions of these matching rules in X.500. The
|
||
caseIgnoreIA5SubstringsMatch rule has also been added to the
|
||
list.
|
||
|
||
26. The specification of the octetStringMatch matching rule from
|
||
RFC 2256 has been added to this document.
|
||
|
||
27. The presentationAddressMatch matching rule has been removed as it
|
||
depends on an assertion syntax (Presentation Address) that is not
|
||
at draft standard maturity.
|
||
|
||
28. The protocolInformationMatch matching rule has been removed as it
|
||
depends on an undefined assertion syntax (Protocol Information).
|
||
|
||
29. The definitive reference for ASN.1 has been changed from X.208 to
|
||
X.680 since X.680 is the version of ASN.1 referred to by X.500.
|
||
|
||
30. The specification of the caseIgnoreListSubstringsMatch matching
|
||
rule from RFC 2798 & X.520 has been added.
|
||
|
||
31. String preparation algorithms have been applied to the character
|
||
string matching rules.
|
||
|
||
32. The specifications of the booleanMatch, caseExactMatch,
|
||
caseExactOrderingMatch, caseExactSubstringsMatch,
|
||
directoryStringFirstComponentMatch, integerOrderingMatch,
|
||
keywordMatch, numericStringOrderingMatch,
|
||
octetStringOrderingMatch and wordMatch matching rules from
|
||
RFC 3698 & X.520 have been added.
