INTERNET-DRAFT Critical Angle Inc.
Expires in six months from 10 Oct. 1997
A Summary of the X.500(96) User Schema for use with LDAPv3
<draft-ietf-asid-ldapv3schema-x500-03.txt>
1. Status of this Memo
This document is an Internet-Draft. 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."
To learn the current status of any Internet-Draft, please check the
"1id-abstracts.txt" listing contained in the Internet-Drafts Shadow
Directories on ds.internic.net (US East Coast), nic.nordu.net (Europe),
ftp.isi.edu (US West Coast), or munnari.oz.au (Pacific Rim).
2. Abstract
This document provides an overview of the attribute types and object
classes defined by the ISO and ITU-T committees in the X.500
documents, in particular those intended for use by directory clients.
This is the most widely used schema for LDAP/X.500 directories, and
many other schema definitions for white pages objects use it as a
basis. This document does not cover attributes used for the
administration of X.500 directory servers, nor does it include
attributes defined by other ISO/ITU-T documents.
3. General Issues
This document references syntaxes given in section 6 of this document
and section 6 of [1]. Matching rules are listed in section 8 of this
document and section 8 of [1].
The attribute type and object class definitions are written using the
BNF form of AttributeTypeDescription and ObjectClassDescription given
in [1]. Lines have been folded for readability.

Three new attributes supportedAlgorithms, deltaRevocationList and
dmdName, and the objectClass dmd, are defined in the X.500(96)
documents.
5. Attribute Types
An LDAP server implementation SHOULD recognize the attribute types
described in this section.
5.1. objectClass
The values of the objectClass attribute describe the kind of object
which an entry represents. The objectClass attribute is present in
every entry, with at least two values. One of the values is either
"top" or "alias".
( 2.5.4.0 NAME 'objectClass' EQUALITY objectIdentifierMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.38 )
5.2. aliasedObjectName
The aliasedObjectName attribute is used by the directory service if
the entry containing this attribute is an alias.
( 2.5.4.1 NAME 'aliasedObjectName' EQUALITY distinguishedNameMatch

The name attribute type is the attribute supertype from which string
attribute types typically used for naming may be formed. It is
unlikely that values of this type itself will occur in an entry.

need not recognize this attribute in requests. Client
implementations MUST NOT assume that LDAP servers are capable of
performing attribute subtyping.

The dnQualifier attribute type specifies disambiguating information to
add to the relative distinguished name of an entry. It is intended
for use when merging data from multiple sources in order to prevent
conflicts between entries which would otherwise have the same name.
It is recommended that the value of the dnQualifier attribute be the
same for all entries from a particular source.

it is instead a base type from which attributes with DN syntax
inherit.

6. Syntaxes
Servers SHOULD recognize the syntaxes defined in this section.
Each syntax begins with a sample value of the ldapSyntaxes attribute
which defines the OBJECT IDENTIFIER of the syntax. The descriptions
of syntax names are not carried in protocol, and are not guaranteed
to be unique.
6.1. Delivery Method
( 1.3.6.1.4.1.1466.115.121.1.14 DESC 'Delivery Method' )
Values in this syntax are encoded according to the following BNF:
delivery-value = pdm / ( pdm whsp "$" whsp delivery-value )
pdm = "any" / "mhs" / "physical" / "telex" / "teletex" /
"g3fax" / "g4fax" / "ia5" / "videotex" / "telephone"
Example:
telephone

6.2. Enhanced Guide
( 1.3.6.1.4.1.1466.115.121.1.21 DESC 'Enhanced Guide' )
Values in this syntax are encoded according to the following BNF:
EnhancedGuide = woid whsp "#" whsp criteria whsp "#" whsp subset
subset = "baseobject" / "oneLevel" / "wholeSubtree"
The criteria production is defined in the Guide syntax below.
This syntax has been added subsequent to RFC 1778.
Example:
person#(sn)#oneLevel
6.3. Guide
( 1.3.6.1.4.1.1466.115.121.1.25 DESC 'Guide' )
Values in this syntax are encoded according to the following BNF:
guide-value = [ object-class "#" ] criteria
object-class = woid
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"
This syntax should not be used for defining new attributes.
6.4. Octet String
( 1.3.6.1.4.1.1466.115.121.1.40 DESC 'Octet String' )
Values in this syntax are encoded as octet strings.
Example:
secret

INTERNET-DRAFT draft-ietf-asid-ldapv3schema-x500-03.txt Oct. 1997
6.5. Teletex Terminal Identifier
( 1.3.6.1.4.1.1466.115.121.1.51 DESC 'Teletex Terminal Identifier' )
Values in this syntax are encoded according to the following BNF:
teletex-id = ttx-term 0*("$" ttx-param)
ttx-term = printablestring
ttx-param = ttx-key ":" ttx-value
ttx-key = "graphic" / "control" / "misc" / "page" / "private"
ttx-value = octetstring
In the above, the first printablestring is the encoding of the
first portion of the teletex terminal identifier to be encoded, and
the subsequent 0 or more octetstrings are subsequent portions
of the teletex terminal identifier.
6.6. Telex Number
( 1.3.6.1.4.1.1466.115.121.1.52 DESC 'Telex Number' )
Values in this syntax are encoded according to the following BNF:
telex-number = actual-number "$" 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.
6.7. Supported Algorithm
( 1.3.6.1.4.1.1466.115.121.1.49 DESC 'Supported Algorithm' )
No printable representation of values of the supportedAlgorithms
attribute is defined in this document. Clients which wish to store
and retrieve this attribute MUST use "supportedAlgorithms;binary", in
which the value is transferred as a binary encoding.
7. Object Classes
LDAP servers MUST recognize the object classes "top" and "subschema".
LDAP servers SHOULD recognize all the other object classes listed here
as values of the objectClass attribute.

8. Matching Rules
Servers MAY implement additional matching rules.
8.1. octetStringMatch
Servers which implement the extensibleMatch filter SHOULD allow
the matching rule listed in this section to be used in the
extensibleMatch. In general these servers SHOULD allow matching
rules to be used with all attribute types known to the server, when
the assertion syntax of the matching rule is the same as the value
syntax of the attribute.

9. Security Considerations
Attributes of directory entries are used to provide descriptive
information about the real-world objects they represent, which can
be people, organizations or devices. Most countries have privacy
laws regarding the publication of information about people.
Transfer of cleartext passwords are strongly discouraged where the
underlying transport service cannot guarantee confidentiality and may
result in disclosure of the password to unauthorized parties.
10. Acknowledgements
The definitions on which this document have been developed by
committees for telecommunications and international standards.
No new attribute definitions have been added. The syntax definitions
are based on the ISODE "QUIPU" implementation of X.500.
