2. Abstract
The Lightweight Directory Access Protocol (LDAP) [1] requires that the
contents of AttributeValue fields in protocol elements be octet
strings. This document defines a set of syntaxes for LDAPv3, and the requirements that must be
satisfied by encoding
rules used to render directory by which attribute values of these syntaxes into a form suitable are represented as
octet strings for use transmission in the LDAP, then goes on to
define the encoding rules for the standard set of attribute LDAP protocol. The syntaxes
of [2],[3]
defined in this document are referenced by this and [4]. It other documents that
define attribute types. This document also identifies all defines the set of attribute types, object
classes and matching rules for
types which LDAP version 3. servers should support.
3. Overview
Section 4 states the general requirements and notations for attribute
types, object classes, syntax and matching rule definitions.
The core definitions are given in section 5, those which are based on
X.500(1993) in
Section 5 lists attributes, section 6, 6 syntaxes and other optional definitions in section 7. 7 object
classes.
4. General Issues
This document describes encodings used in an Internet protocol. Terms are
defined in [4].

4. General Issues LDAPv3 Attribute Syntax Definitions March 1997
4.1. Attribute Types
The attribute types are described by sample values for the subschema
"attributeTypes" attribute, which is written in the
AttributeTypeDescription syntax. While lines have been folded for
readability, the values transferred in protocol would not contain
newlines.
The AttributeTypeDescription is encoded according to the following BNF,
and the productions for <oid>, <DirectoryStrings> and <DirectoryString>
are given in sections 4.2.1.
<AttributeTypeDescription> ::= "("
<oid> -- AttributeType identifier
[ "NAME" <DirectoryStrings> ] -- name used in AttributeType
[ "DESC" <DirectoryString> ]
[ "OBSOLETE" ]
[ "SUP" <oid> ] -- derived from this other AttributeType
[ "EQUALITY" <oid> ] -- Matching Rule name
[ "ORDERING" <oid> ] -- Matching Rule name
[ "SUBSTR" <oid> ] -- Matching Rule name
[ "SYNTAX" <DirectoryString> ] -- see section 4.2
[ "SINGLE-VALUE" ] -- default multi-valued
[ "COLLECTIVE" ] -- default not collective
[ "NO-USER-MODIFICATION" ] -- default user modifiable
[ "USAGE" <AttributeUsage> ] -- default user applications
")"
<AttributeUsage> ::=
"userApplications"
| "directoryOperation"
| "distributedOperation" -- DSA-shared
| "dSAOperation" -- DSA-specific, value depends on server
Servers are not required to provide the same or any text
in the description part of the subschema values they maintain.
Servers must SHOULD implement all the attribute types referenced in section 5.1, and
may also implement the types listed in sections 6.1 and 7.1. Servers must 5:
they MUST be able to perform equality matching of values, but need not
perform any additional validity checks on attribute values.
Servers may MAY recognize additional names and attributes not listed in this
document. Later documents may define additional types.
Servers may implement additional attribute types not listed in this
document, and if they do so, must SHOULD publish the definitions of the types
in the attributeTypes attribute of their subschema subentries.
AttributeDescriptions may can be used as the value in a NAME part of an
AttributeTypeDescription. Note that these are case insensitive.

4.2. Syntaxes
This section defines general requirements for LDAP attribute value
syntax encodings. All documents defining attribute syntax encodings for
use with LDAP are expected to conform to these requirements.
Wahl, Coulbeck, Howes, Kille Page 2
INTERNET-DRAFT LDAPv3 Attribute Syntax Definitions March 1997
The encoding rules defined for a given attribute syntax must produce
octet strings. To the greatest extent possible, encoded octet
strings should be usable in their native encoded form for display
purposes. In particular, encoding rules for attribute syntaxes
defining non-binary values should produce strings that can be
displayed with little or no translation by clients implementing
LDAP. There are a few cases (e.g. Audio) however, when it is not sensible
to produce a printable representation, and clients must not MUST NOT assume that
an unrecognized syntax is a string representation.
4.2.1. Common Encoding Aspects
In these encodings where an arbitrary string is used as part of a larger
production (other than a Distinguished Name), a backslash quoting mechanism
is used to encode the following separator symbol character (such as ''',
'$' or '#') if it should occur in that string. The backslash is followed
by a pair of hexadecimal digits representing the next character. A
backslash itself in the string which forms part of a larger syntax is
always transmitted as '\5C' or '\5c'.
For the purposes of defining the encoding rules for attribute syntaxes,
the following auxiliary BNF definitions will be used:
<a> ::= 'a' | 'b' | 'c' | 'd' | 'e' | 'f' | 'g' | 'h' | 'i' |
'j' | 'k' | 'l' | 'm' | 'n' | 'o' | 'p' | 'q' | 'r' |
's' | 't' | 'u' | 'v' | 'w' | 'x' | 'y' | 'z' | 'A' |
'B' | 'C' | 'D' | 'E' | 'F' | 'G' | 'H' | 'I' | 'J' |
'K' | 'L' | 'M' | 'N' | 'O' | 'P' | 'Q' | 'R' | 'S' |
'T' | 'U' | 'V' | 'W' | 'X' | 'Y' | 'Z'
<d> ::= '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'
<hex-digit> ::= <d> | 'a' | 'b' | 'c' | 'd' | 'e' | 'f' |
'A' | 'B' | 'C' | 'D' | 'E' | 'F'
<k> ::= <a> | <d> | '-'
<p> ::= <a> | <d> | ''' | '(' | ')' | '+' | ',' | '-' | '.' |
'/' | ':' | '?' | ' '
<letterstring> ::= <a> | <a> <letterstring>
<numericstring> ::= <d> | <d> <numericstring>
<keystring> ::= <a> | <a> <anhstring>
<anhstring> ::= <k> | <k> <anhstring>
Wahl, Coulbeck, Howes & Kille [Page 3]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
<printablestring> ::= <p> | <p> <printablestring>
<space> ::= ' ' | ' ' <space>
<whsp> ::= <space> | empty
Wahl, Coulbeck, Howes, Kille Page 3
INTERNET-DRAFT LDAPv3 Attribute Syntax Definitions March 1997
<utf8> ::= any sequence of octets formed from the UTF-8 [11] [9]
transformation of a character from ISO 10646 [12] [10]
<dstring> ::= <utf8> | <utf8> <dstring>
<DirectoryStrings> ::= <DirectoryString> | '(' <DirectoryStringList> ')'
<DirectoryStringList> ::= <DirectoryStringList> <DirectoryString> | ""
<DirectoryString> ::= ''' <dstring> '''
<oids> ::= <oid> | '(' <oidlist> ')'
<oidlist> ::= <oidlist> '$' <oid> | <oid>
-- <oid> is defined in 5.2.1.15
4.2.2 Binary Transfer of Values
This encoding format is used if the binary encoding is requested by the
client for an attribute, or if the attribute syntax name is 'Binary'. The
value, an instance of the ASN.1 AttributeValue type, is BER-encoded,
subject to the restrictions of section 5.1 of [1], and this sequence of
octets is used as the value.
All servers must MUST implement this form for both generating Search responses attribute values in
search responses, and parsing Add, Compare attribute values in add, compare and modify
requests, if the attribute type is recognized and Modify requests. the attribute syntax name
is 'Binary'. Clients must MUST be prepared receiving values in binary (e.g.
userCertificate or audio), and must not MUST NOT simply display binary or
unrecognized values to users.
4.2.3. Syntax Namees Names
Names of syntaxes for use with LDAP are ASCII strings which either
begin with a letter and contain only letters or digits. The names are
case insensitive. Historically since syntaxes correspond to ASN.1 types,
they have been named starting with a capital letter. A suggested minimum
upper bound on the number of characters in value with a DirectoryString or
IA5String syntax or the number of bytes in a value for all other syntaxes
may be indicated by appending this bound count inside of curly braces, e.g.
"DirectoryString{64}". Note braces.
For instance, "DirectoryString{64}" suggests that server implementations
should allow the string to be 64 characters long, althoough they may allow
longer strings. Note that a single character of the DirectoryString may be
encoded in more than one byte since UTF-8 is a variable-length encoding.
Syntax names do not have global scope: two clients or servers may
know of different syntaxes with the same name.
Wahl, Coulbeck, Howes & Kille [Page 4]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
The definition of additional arbitrary syntaxes is strongly depreciated
since it will hinder interoperability: today's client and server
implementations generally do not have the ability to dynamically recognize
new syntaxes. In most cases attributes will be defined with the
DirectoryString syntax.
The following syntax names are used for attributes in this document.
Servers are only required to implement the syntaxes in section 5.2.
AccessPoint ACIItem
AttributeTypeDescription Audio
Binary BitString
Certificate CertificateList
CertificatePair DataQualitySyntax

4.3. Object Classes
These are described as sample values for the subschema "objectClasses"
attribute for a server which implements the LDAP schema.
While lines have been folded for readability, the values transferred in
protocol would not contain newlines.
Object class descriptions are written according to the following BNF:
<ObjectClassDescription> ::= "("
<oid> -- ObjectClass identifier
[ "NAME" <DirectoryStrings> ]
[ "DESC" <DirectoryString> ]
[ "OBSOLETE" ]
[ "SUP" <oids> ] -- Superior ObjectClasses
[ ( "ABSTRACT" | "STRUCTURAL" | "AUXILIARY" ) ] -- default structural
[ "MUST" <oids> ] -- AttributeTypes
[ "MAY" <oids> ] -- AttributeTypes
")"
Wahl, Coulbeck, Howes & Kille [Page 5]
INTERNET-DRAFT
These are described as sample values for the subschema "objectClasses"
attribute for a server which implements the LDAP Standard and Pilot Attributes October 1996 schema.
While lines have been folded for readability, the values transferred in
protocol would not contain newlines.
Servers must SHOULD implement all the object classes referenced in section 5.3:
account alias
applicationEntity applicationProcess
certificationAuthority country
dNSDomain dSA
device document
documentSeries domain
domainRelatedObject friendlyCountry
groupOfNames groupOfUniqueNames
locality newPilotPerson
organization organizationalPerson
organizationalRole organizationalUnit
person pilotDSA
pilotObject pilotOrganization
qualityLabelledData rFC822localPart
residentialPerson room
simpleSecurityObject strongAuthenticationUser
top
and may also implement the object classes of 6.3 and 7.3. 7,
except for extensibleObject, which is optional.
Servers may MAY implement additional object classes not listed in this
document, and if they do so, must SHOULD publish the definitions of the classes
in the objectClasses attribute of their subschema subentries. Later
documents may define additional object classes.
4.4. Matching Rules
Matching rules are used by servers to compare attribute values against
assertion values when performing Search and Compare operations.
Most of the attributes given in this document will have an equality
matching rule defined.
Matching rule descriptions are written according to the following BNF:
<MatchingRuleDescription> ::= "("
<oid> -- MatchingRule identifier
[ "NAME" <DirectoryStrings> ]
[ "DESC" <DirectoryString> ]
[ "OBSOLETE" ]
"SYNTAX" <DirectoryString>
")"
Servers must SHOULD implement all the matching rules in section 5.4:
bitStringMatch caseExactIA5Match
caseIgnoreIA5Match caseIgnoreListMatch
caseIgnoreMatch distinguishedNameMatch
generalizedTimeMatch integerMatch
numericStringMatch objectIdentifierMatch
octetStringMatch telephoneNumberMatch
and may also implement the matching rules of 6.4 and 7.4.
Wahl, Coulbeck, Howes & Kille [Page 6]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996 8.
Servers may MAY implement additional matching rules not listed in this
document, and if they do so, must SHOULD publish the definitions of the
matching rules in the matchingRules attribute of their
subschema subentries.

6. Syntaxes
Servers SHOULD recognize all the syntaxes described in this section
(6.1 - 6.3).
6.1. AttributeTypeDescription
Values with this syntax are encoded according to the BNF given at the
start of section 4.1. For example,
( 0.9.2342.19200300.100.1.11 2.5.4.0 NAME 'documentIdentifier'
EQUALITY caseIgnoreMatch SUBSTRINGS caseIgnoreSubstringsMatch 'objectClass' SYNTAX 'DirectoryString{256}' 'OID' )
6.2. Audio
The encoding of a value with Audio syntax is the octets of the value
itself, an 8KHz uncompressed encoding compatible with the SunOS
4.1.3 'play' utility.
6.3. BitString
The encoding of a value with BitString syntax is according to the
following BNF:
<bitstring> ::= ''' <binary-digits> ''B'
<binary-digits> ::= '0' <binary-digits> | '1' <binary-digits> |
empty
Example:
'0101111101'B
Wahl, Coulbeck, Howes & Howes, Kille [Page 10] Page 8
INTERNET-DRAFT LDAP Standard LDAPv3 Attribute Syntax Definitions March 1997
6.4. Boolean
Values with Boolean syntax are encoded according to the following
BNF:

INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
5.2. Syntaxes
5.2.1. Standard User Syntaxes
Servers must recognize all the syntaxes described in this section.
5.2.1.1. BitString
The encoding of a value with BitString syntax is according to the
following BNF:
<bitstring> ::= ''' <binary-digits> ''B'
<binary-digits> ::= '0' <binary-digits> | '1' <binary-digits> |
empty
5.2.1.2. PrintableString
The encoding of a value with PrintableString syntax is the string
value itself. PrintableString is limited to the characters in
production <p> of section 4.1.
5.2.1.3. DirectoryString
A string with DirectoryString syntax is encoded in the UTF-8 form of
ISO 10646 (a superset of Unicode). Servers and clients must be prepared to
receive arbitrary Unicode characters in values.
For characters in the PrintableString form, the value is encoded as the
string value itself.
If it is of the TeletexString form, then the characters are transliterated
to their equivalents in UniversalString, and encoded in UTF-8 [11].
If it is of the UniversalString or BMPString forms [12], UTF-8 is used to
encode them.
Note: the form of DirectoryString is not indicated in protocol unless the
attribute value is carried in binary. Servers which convert to DAP must
choose an appropriate form. Servers must not reject values merely because
they contain legal Unicode characters outside of the range of printable
ASCII.
5.2.1.4. Certificate
Because of the changes from X.509(1988) and X.509(1993) and additional
changes to the ASN.1 definition to support certificate extensions, no
string representation is defined, and values with Certificate syntax
must only be transferred using the binary encoding, by requesting or
returning the attributes with descriptions "userCertificate;binary" or
"caCertificate;binary". The BNF notation in RFC 1778 for
"User Certificate" is not recommended to be used.
Wahl, Coulbeck, Howes & Kille [Page 16]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
5.2.1.5. CertificateList
Because of the incompatibility of the X.509(1988) and X.509(1993)
definitions of revocation lists, values with CertificateList syntax
must only be transferred using a binary encoding, by requesting or
returning the attributes with descriptions
"certificateRevocationList;binary" or "authorityRevocationList;binary".
The BNF notation in RFC 1778 for "Authority Revocation List" is not
recommended to be used.
5.2.1.6. CertificatePair
Because the Certificate is being carried in binary, values with
CertificatePair syntax must only be transferred using a binary encoding,
by requesting or returning the attribute description
"crossCertificatePair;binary". The BNF notation in RFC 1778 for
"Certificate Pair" is not recommended to be used.
5.2.1.7. CountryString
A value of CountryString syntax is encoded the same as a value of
DirectoryString syntax. Note that this syntax is limited to values of
exactly two printable string characters.
<CountryString> ::= <p> <p>
5.2.1.8. DN
Values with DN (Distinguished Name) syntax are encoded to have the
representation defined in [5]. Note that this representation is not
reversible to the original ASN.1 encoding as the CHOICE of any
DirectoryString element in an RDN is no longer known.
5.2.1.9. DeliveryMethod
Values with DeliveryMethod syntax are encoded according to the
following BNF:
<delivery-value> ::= <pdm> | <pdm> '$' <delivery-value>
<pdm> ::= 'any' | 'mhs' | 'physical' | 'telex' | 'teletex' |
'g3fax' | 'g4fax' | 'ia5' | 'videotex' | 'telephone'
5.2.1.10. EnhancedGuide
Values with the EnhancedGuide syntax are encoded according to the
following BNF:
<EnhancedGuide> ::= <objectclass> '#' <criteria> '#' <subset>
<subset> ::= "baseobject" | "oneLevel" | "wholeSubtree"
Wahl, Coulbeck, Howes & Kille [Page 17]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
The <criteria> production is defined in the Guide syntax below.
This syntax has been added subsequent to RFC 1778.
5.2.1.11. FacsimileTelephoneNumber
Values with the FacsimileTelephoneNumber syntax are encoded according
to the following BNF:
<fax-number> ::= <printablestring> [ '$' <faxparameters> ]
<faxparameters> ::= <faxparm> | <faxparm> '$' <faxparameters>
<faxparm> ::= 'twoDimensional' | 'fineResolution' | 'unlimitedLength' |
'b4Length' | 'a3Width' | 'b4Width' | 'uncompressed'
In the above, the first <printablestring> is the actual fax number,
and the <faxparm> tokens represent fax parameters.
5.2.1.12. Guide
Values with the Guide syntax are encoded according to the following
BNF:
<guide-value> ::= [ <object-class> '#' ] <criteria>
<object-class> ::= an encoded value with OID syntax
<criteria> ::= <criteria-item> | <criteria-set> | '!' <criteria>
<criteria-set> ::= [ '(' ] <criteria> '&' <criteria-set> [ ')' ] |
[ '(' ] <criteria> '|' <criteria-set> [ ')' ]
<criteria-item> ::= [ '(' ] <attributetype> '$' <match-type> [ ')' ]
<match-type> ::= "EQ" | "SUBSTR" | "GE" | "LE" | "APPROX"
5.2.1.13. NameAndOptionalUID
The encoding of a value with the NameAndOptionalUID syntax is according
to the following BNF:
<NameAndOptionalUID> ::=
<DistinguishedName> [ '#' <BitString> ]
Although the '#' character may occur in a string representation of a
distinguished name, no additional special quoting is done in the
distinguished name other than that of [5].
This syntax has been added subsequent to RFC 1778.
Wahl, Coulbeck, Howes & Kille [Page 18]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
5.2.1.14. NumericString
The encoding of a string with the NumericString syntax is the string
value itself.
5.2.1.15. OID
Values with OID (Object Identifier) syntax are encoded according to the
following BNF:
<oid> ::= <descr> | <numericoid>
<descr> ::= <keystring>
<numericoid> ::= <numericstring> | <numericstring> '.' <numericoid>
In the above BNF, <descr> is the syntactic representation of an
object descriptor, which must consist of letters and digits, starting
with a letter. When encoding values with OID syntax, the first encoding
option must be used in preference to the second. That is, in encoding
object identifiers, object descriptors (where assigned and known by
the implementation) must be used in preference to numeric oids to
the greatest extent possible. All permitted object descriptors for use
in LDAP are given in this document. No other object descriptors may be
used. (Note that clients must expect that LDAPv2 implementations
will return object descriptors other than those listed.)
5.2.1.16. Password
Values with Password syntax are encoded as octet strings.
5.2.1.17. PostalAddress
Values with the PostalAddress syntax are encoded according to the
following BNF:
<postal-address> ::= <dstring> | <dstring> '$' <postal-address>
In the above, each <dstring> component of a postal address value is
encoded as a value of type DirectoryString syntax. Backslashes and
dollar characters, if they occur in the component, are quoted as
described in section 4.2.
5.2.1.18. PresentationAddress
Values with the PresentationAddress syntax are encoded to have the
representation described in [6].
5.2.1.20. TelephoneNumber
Values with the TelephoneNumber syntax are encoded as if they were
Printable String types. Telephone numbers are recommended in X.520 to
be in international form, e.g. "+1 512 305 0280".
Wahl, Coulbeck, Howes & Kille [Page 19]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
5.2.1.21. TeletexTerminalIdentifier
Values with the TeletexTerminalIdentifier syntax are encoded according
to the following BNF:
<teletex-id> ::= <ttx-term> 0*('$' <ttx-param>)
<ttx-term> ::= <printablestring>
<ttx-param> ::= <ttx-key> ':' <ttx-value>
<ttx-key> ::= 'graphic' | 'control' | 'misc' | 'page' | 'private'
<ttx-value> ::= <octetstring>
In the above, the first <printablestring> is the encoding of the
first portion of the teletex terminal identifier to be encoded, and
the subsequent 0 or more <octetstrings> are subsequent portions
of the teletex terminal identifier.
5.2.1.22. TelexNumber
Values with the TelexNumber syntax are encoded according to the
following BNF:
<telex-number> ::= <actual-number> '$' <country> '$' <answerback>
<actual-number> ::= <printablestring>
<country> ::= <printablestring>
<answerback> ::= <printablestring>
In the above, <actual-number> is the syntactic representation of the
number portion of the TELEX number being encoded, <country> is the
TELEX country code, and <answerback> is the answerback code of a
TELEX terminal.
5.2.1.23. UTCTime
Values with UTCTime syntax are encoded as if they were printable
strings with the strings containing a UTCTime value. This is historical;
new attribute definitions must use GeneralizedTime instead.
5.2.1.24. Boolean
Values with Boolean syntax are encoded according to the following
BNF:
<boolean> ::= "TRUE" | "FALSE"
Boolean values have an encoding of "TRUE" if they are logically true,
and have an encoding of "FALSE" otherwise.
Wahl, Coulbeck, Howes & Kille [Page 20]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
5.2.2. Pilot Syntaxes
Servers must recognize all the syntaxes described in this section.
5.2.2.1. Audio
The encoding of a value with Audio syntax is the octets of the value
itself, an 8KHz uncompressed encoding compatible with the SunOS
4.1.3 'play' utility.
5.2.2.2. DSAQualitySyntax
Values with this syntax are encoded according to the following BNF:
<DsaQualitySyntax> ::= <DSAKeyword> [ '#' <description> ]
<DSAKeyword> ::= 'DEFUNCT' | 'EXPERIMENTAL' | 'BEST-EFFORT' |
'PILOT-SERVICE' | 'FULL-SERVICE'
<description> ::= encoded as a PrintableString
5.2.2.3. DataQualitySyntax
Values with this syntax are encoded according to the following BNF:
<DataQualitySyntax> ::= <compKeyword> '#' <attrQuality> '#'
<listQuality> [ '#' <description> ]
<attrQuality> ::= <levelKeyword> '+' <compKeyword>
<listQuality> ::= <list> '$' <list><listQuality>
<list> ::= <attribute> '+' <attrQuality>
<compKeyword> ::= 'NONE' | 'SAMPLE' | 'SELECTED' |
'SUBSTANTIAL' | 'FULL'
<levelKeyword> ::= 'UNKNOWN' | 'EXTERNAL' | 'SYSTEM-MAINTAINED' |
'USER-SUPPLIED'
5.2.2.4. IA5String
The encoding of a value with IA5String syntax is the string value
itself.
5.2.2.5. JPEG
Values with JPEG syntax are encoded as if they were octet strings
containing JPEG images in the JPEG File Interchange Format (JFIF), as
described in [8].
Wahl, Coulbeck, Howes & Kille [Page 21]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
5.2.2.6. MailPreference
Values with MailPreference syntax are encoded according to the
following BNF:
<mail-preference> ::= "NO-LISTS" | "ANY-LIST" | "PROFESSIONAL-LISTS"
5.2.2.7. OtherMailbox
Values of the OtherMailbox syntax are encoded according to the
following BNF:
<otherMailbox> ::= <mailbox-type> '$' <mailbox>
<mailbox-type> ::= an encoded Printable String
<mailbox> ::= an encoded IA5 String
In the above, <mailbox-type> represents the type of mail system in
which the mailbox resides, for example "MCIMail"; and <mailbox> is the
actual mailbox in the mail system defined by <mailbox-type>.
5.2.2.8. Fax
Values with Fax syntax are encoded as if they were octet strings
containing Group 3 Fax images as defined in [7].
5.2.3. Operational Syntaxes
Servers must recognize all the syntaxes described in this section.
5.2.3.1. AttributeTypeDescription
Values with this syntax are encoded according to the BNF given at the
start of section 4.1. For example,
( 2.5.4.0 NAME 'objectClass' SYNTAX 'OID' )
5.2.3.2. GeneralizedTime
Values of this syntax are encoded as printable strings, represented
as specified in X.208. Note that the time zone must be specified.
It is strongly recommended that Zulu time zone be used. For example,
199412161032Z
5.2.3.3. INTEGER
Values with INTEGER syntax are encoded as the decimal representation
of their values, with each decimal digit represented by the its
character equivalent. So the number 1321 is represented by the character
string "1321".

5.2.3.4. ObjectClassDescription
Values of this syntax are encoded according to the BNF in section 4.3.
5.3. Object Classes
5.3.1. Standard Classes
Servers must recognize the object classes listed here as values of
the objectClass attribute. With the exception of groupOfUniqueNames,
they are described in RFC 1274.

5.4. Matching Rules
Servers must recognize the following matching rules, used for equality
matching, and must be capable of performing the matching rules.
For all these rules, the assertion syntax is the same as the value syntax.
( 2.5.13.0 NAME 'objectIdentifierMatch' SYNTAX 'OID' )
( 2.5.13.1 NAME 'distinguishedNameMatch' SYNTAX 'DN' )
( 2.5.13.2 NAME 'caseIgnoreMatch' SYNTAX 'DirectoryString' )

( 1.3.6.1.4.1.1466.109.114.2 NAME 'caseIgnoreIA5Match' SYNTAX 'IA5String' )
When performing the caseIgnoreMatch, caseIgnoreListMatch,
telephoneNumberMatch, caseExactIA5Match and caseIgnoreIA5Match,
multiple adjoining whitespace characters are treated the same as
an individual space, and leading and trailing whitespace is ignored.
6. X.500 Definitions
Servers which implement the X.500(1993) protocols are required to recognize
these attributes types, syntaxes, object classes and matching rules, where
they correspond to X.500 features implemented by that server. No other
servers are required to implement any definitions in section 6, although
they may do so.
Clients must not assume these definitions are recognized by all servers.
6.1. Attribute Types
6.1.1. User Attributes
All user attributes of X.500 are listed in section 5.1.1.
Wahl, Coulbeck, Howes & Kille [Page 26]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
6.1.2. Collective Attributes
These attributes are stored in collective attribute subentries, but may
be visible in user entries if requested.
Each of these collective attributes is a subtype of the attribute which
has the OID without the final ".1", e.g. "collectivePostalCode" is a
subtype of "postalCode".

CertificatePair syntax MUST only be transferred using a binary encoding,
by requesting or returning the attribute description
"crossCertificatePair;binary". The BNF notation in RFC 1778 for
"Certificate Pair" is not recommended to be used.
6.8. CountryString
A value of CountryString syntax is encoded the same as a value of
DirectoryString syntax. Note that this attribute may be supplied in an AddEntry operation syntax is limited to inform the Directory values of
exactly two printable string characters.
<CountryString> ::= <p> <p>
Example:
US
Wahl, Coulbeck, Howes, Kille Page 9
INTERNET-DRAFT LDAPv3 Attribute Syntax Definitions March 1997
6.9. DN
Values with DN (Distinguished Name) syntax are encoded to have the target server on which the entry
representation defined in [5]. Note that this representation is not
reversible to
be held. This is an ASN.1 encoding used to create a new naming context in X.500 for Distinguished Names, as
the directory
tree. A server which does not permit the use CHOICE of this attribute must
return any DirectoryString element in an appropriate error code if it RDN is present no longer known.
Examples (from [5]):
CN=Steve Kille,O=Isode Limited,C=GB
OU=Sales+CN=J. Smith,O=Widget Inc.,C=US
CN=L. Eagle,O=Sue\, Grabbit and Runn,C=GB
CN=Before\0DAfter,O=Test,C=GB
1.3.6.1.4.1.1466.0=#04024869,O=Test,C=GB
SN=Lu\C4\8Di\C4\C7
6.10. DirectoryString
A string with DirectoryString syntax is encoded in the attribute list.
This attribute will generally not UTF-8 form of
ISO 10646 (a superset of Unicode). Servers and clients MUST be present prepared to
receive encodings of arbitrary Unicode characters, including characters
not presently assigned to any character set, in values.
For characters in the entry after PrintableString form, the add value is completed.
Wahl, Coulbeck, Howes & Kille [Page 29]
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
6.2. Syntaxes
6.2.1. Standard Syntaxes
6.2.1.1. ACIItem
This syntax appears too complicated for a compact encoded as the
string representation
to be useful. Clients must only request and servers must only return
values which use value itself.
If it is of the TeletexString form, then the binary encoding characters are transliterated
to their equivalents in UniversalString, and encoded in UTF-8 [9].
If it is of the value, e.g.
"entryACI;binary".
It UniversalString or BMPString forms [10], UTF-8 is recommended that clients that wish to only determine whether they
have been granted permission used to modify an entry use
encode them.
Note: the form of DirectoryString is not indicated in protocol unless the "modifyRights"
attribute rather than attempt to parse this syntax.
6.2.1.2. AccessPoint
Values with AccessPoint syntax are encoded according value is carried in binary. Servers which convert to DAP MUST
choose an appropriate form. Servers MUST NOT reject values merely because
they contain legal Unicode characters outside of the
following BNF:
<AccessPoint> ::= ( '(' <DistinguishedName> '#'
<PresentationAddress> ')' ) |
-- Optional protocol info absent, parenthesis required
( '(' <DistinguishedName> '#'
<PresentationAddress> '#'
<SetOfProtocolInformation ')' )
<SetOfProtocolInformation> ::= <ProtocolInformation> |
'(' <ProtocolInformationList> ')'
<ProtocolInformationList> ::= <ProtocolInformation> |
<ProtocolInformation> '$'
<ProtocolInformationList>
6.2.1.3. range of printable
ASCII.
Example:
This is a string of DirectoryString containing #!%#@
6.11. DITContentRuleDescription
Values with this syntax are encoded according to the following BNF:
<DITContentRuleDescription> ::= "("
<oid> -- Structural ObjectClass identifier
[ "NAME" <DirectoryStrings> ]

In the above, the first <printablestring> is the actual fax number,
and the <faxparm> tokens represent fax parameters.
6.13. Fax
Values with Fax syntax are encoded as if they were octet strings
containing Group 3 Fax images as defined in [7].
6.14. GeneralizedTime
Values of this syntax are encoded as printable strings, represented
as specified in X.208. Note that the time zone must be specified.

of this their values, with each decimal digit represented by the its
character equivalent. So the number 1321 is represented by the character
string "1321".
6.17. JPEG

containing JPEG images in the BNF of section 4.4. JPEG File Interchange Format (JFIF), as
described in [8].

6.19. MHSORAddress
Values of type MHSORAddress are encoded as strings, according to
the format defined in [11].
6.20. NameAndOptionalUID
The encoding of a value with the NameAndOptionalUID syntax is according
to the following BNF:
<NameAndOptionalUID> ::=
<DistinguishedName> [ '#' <bitstring> ]
Although the '#' character may occur in a string representation of a
distinguished name, no additional special quoting is done.
This syntax has been added subsequent to RFC 1778.

6.23. ObjectClassDescription
Values of this syntax are encoded according to the following BNF:
<SupplierInformation> ::=
-- supplier is master --
'(' 'master' '#' <SupplierOrConsumer> ')' |
-- supplier is not master, master unspecified --
'(' 'shadow' '#' <SupplierOrConsumer> ')' |
-- supplier not master, master specified --

6.2.1.13. SupplierAndConsumers
Values '.' <numericoid>
In the above BNF, <descr> is the syntactic representation of an
object descriptor, which consists of letters and digits, starting
with a letter. When encoding values with OID syntax, the first encoding
option MUST be used in preference to the second. That is, in encoding
object identifiers, object descriptors (where assigned and known by
the implementation) must be used in preference to numeric oids to
the greatest extent possible. All permitted object descriptors for use
in LDAP are given in this document. No other object descriptors may be
used. (Note that clients should expect that LDAPv2 implementations
will return object descriptors other than those listed.)
Example:
1.2.3.4

6.3. Object Classes
The following object classes may be recognized.
( 2.5.17.0 NAME 'subentry' SUP top STRUCTURAL
MUST ( cn $ subtreeSpecification ) )
( 2.5.17.1 NAME 'accessControlSubentry' AUXILIARY )
( 2.5.17.2 NAME 'collectiveAttributeSubentry' AUXILIARY )
( 2.5.20.1 NAME 'subschema' AUXILIARY
MAY ( dITStructureRules $ nameForms $ ditContentRules $
objectClasses $ attributeTypes $ matchingRules $ matchingRuleUse ) )
6.4. Matching Rules
Only servers which implement
dollar characters, if they occur in the attribute types which reference these
matching rules component, are quoted as
described in their definition section 4.2.
Example:
1234 Main St.$Anytown, CA 12345$USA
\241,000,000 Sweepstakes$PO Box 1000000$Anytown, CA 12345$USA
6.28. PresentationAddress
Values with the PresentationAddress syntax are required encoded to implement these rules.
The definitions of have the rules can be found
representation described in [2] and [3].

6.29. PrintableString
The string 'excludeAllCollectiveAttributes' is defined as encoding of a synonym
for value with PrintableString syntax is the OID 2.5.18.0. It would typically be used as a string
value of itself. PrintableString is limited to the
collectiveExclusions attribute.
7. Other Optional Definitions
7.1. Attribute Types
7.1.1. Obsolete Attributes
Implementors must use modifyTimestamp and modifiersName instead.
( 0.9.2342.19200300.100.1.23 NAME 'lastModifiedTime' OBSOLETE
SYNTAX 'UTCTime' )
( 0.9.2342.19200300.100.1.24 NAME 'lastModifiedBy' OBSOLETE
EQUALITY distinguishedNameMatch SYNTAX 'DN' )
7.2. Syntaxes
7.2.1 MHSORAddress
Values characters in
production <p> of type MHSORAddress section 4.1.
Example:
This is a PrintableString
6.30. TelephoneNumber
Values with the TelephoneNumber syntax are encoded as strings, according if they were
Printable String types. Telephone numbers are recommended in X.520 to
the format defined
be in [10].
7.2.2 DLSubmitPermission international form.
Example:
+1 512 305 0280
6.31. UTCTime
Values of type DLSubmitPermission with UTCTime syntax are encoded as strings, according
to if they were printable
strings with the following BNF:
<dlsubmit-perm> ::= <dlgroup_label> ':' <dlgroup-value>
| <dl-label> ':' <dl-value>
<dlgroup-label> ::= 'group_member'
<dlgroup-value> ::= <name>
<name> ::= an encoded Distinguished Name
<dl-label> ::= 'individual' | 'dl_member' | 'pattern'
<dl-value> ::= <orname> strings containing a UTCTime value. This is historical;
new attribute definitions will use GeneralizedTime instead.
Wahl, Coulbeck, Howes & Howes, Kille [Page 36] Page 14
INTERNET-DRAFT LDAP Standard and Pilot Attributes October 1996
<orname> ::= <address> '#' <dn>
| <address>
<address> ::= <add-label> ':' <oraddress>
<dn> ::= <dn-label> ':' <name>
<add-label> = 'X400'
<dn-label> = 'X500'
where <oraddress> is as defined in RFC 1327.
7.3. LDAPv3 Attribute Syntax Definitions March 1997
7. Object Classes
7.3.1. Obsolete Classes
( 0.9.2342.19200300.100.4.22 NAME 'oldQualityLabelledData' SUP top
STRUCTURAL MUST dSAQuality
MAY ( subtreeMaximumQuality $ subtreeMinimumQuality ) )
Servers SHOULD recognize all the names of standard classes from section
7 of [12], as well as the names of the Internet classes from section
7 of [13].
7.1. Extensible Object Class
The oldQualityLabelledData object class is historical and must not be
used for defining new objects.
7.3.2. extensibleObject
( 1.3.6.1.4.1.1466.101.120.111 NAME 'extensibleObject'
SUP top AUXILIARY )
This object class, if present in an entry, permits that
entry to optionally hold any attribute. The MAY attribute list of this
class is implicitly the set of all attributes known to the server.
( 1.3.6.1.4.1.1466.101.120.111 NAME 'extensibleObject'
SUP top AUXILIARY )
The mandatory attributes of the other object classes of this entry are
still required to be present.
Note that not all servers will implement this object class, and those
which do not will reject requests to add entries which contain this
object class, or modify an entry to add this object class.
7.4.
8. Matching Rules
7.4.1. caseIgnoreIA5SubstringsMatch
Servers which implement extensibleMatch SHOULD recognize the following
matching rules, used for equality matching, and be capable of
performing the matching rules. For all these rules, the
assertion syntax is the same as the value syntax.
( 2.5.13.0 NAME 'objectIdentifierMatch' SYNTAX 'OID' )
( 2.5.13.1 NAME 'distinguishedNameMatch' SYNTAX 'DN' )
( 2.5.13.2 NAME 'caseIgnoreMatch' SYNTAX 'DirectoryString' )
( 2.5.13.8 NAME 'numericStringMatch' SYNTAX 'NumericString' )
( 2.5.13.11 NAME 'caseIgnoreListMatch' SYNTAX 'PostalAddress' )
( 2.5.13.14 NAME 'integerMatch' SYNTAX 'INTEGER' )
( 2.5.13.16 NAME 'bitStringMatch' SYNTAX 'BitString' )
( 2.5.13.17 NAME 'octetStringMatch' SYNTAX 'Password' )
( 2.5.13.20 NAME 'telephoneNumberMatch' SYNTAX 'TelephoneNumber' )
( 2.5.13.22 NAME 'presentationAddressMatch' SYNTAX 'PresentationAddress' )
( 2.5.13.23 NAME 'uniqueMemberMatch' SYNTAX 'NameAndOptionalUID' )
( 2.5.13.24 NAME 'protocolInformationMatch' SYNTAX 'ProtocolInformation' )
( 2.5.13.27 NAME 'generalizedTimeMatch' SYNTAX 'GeneralizedTime' )
( 1.3.6.1.4.1.1466.109.114.3 1.3.6.1.4.1.1466.109.114.1 NAME 'caseIgnoreIA5SubstringsMatch' 'caseExactIA5Match' SYNTAX 'IA5String' )
This matching rule may be used to compare components of an IA5 string
against
( 1.3.6.1.4.1.1466.109.114.2 NAME 'caseIgnoreIA5Match' SYNTAX 'IA5String' )
When performing the caseIgnoreMatch, caseIgnoreListMatch,
telephoneNumberMatch, caseExactIA5Match and caseIgnoreIA5Match,
multiple adjoining whitespace characters are treated the same as an attribute whose values have IA5 string syntax.
