INTERNET-DRAFT     LDAP: Schema for User Applications   January 30, 2006


Abstract

   This document is an integral part of the Lightweight Directory Access
   Protocol (LDAP) technical specification [Roadmap].  It provides a
   technical specification of attribute types and object classes
   intended for use by LDAP directory clients for many directory
   services, such as, White Pages.  These objects are widely used as a
   basis for the schema in many LDAP directories.  This document does
   not cover attributes used for the administration of directory
   servers, nor does it include directory objects defined for specific
   uses in other documents.

INTERNET-DRAFT     LDAP: Schema for User Applications   January 30, 2006


1.  Introduction

   This document provides an overview of attribute types and object
   classes intended for use by Lightweight Directory Access Protocol
   (LDAP) directory clients for many directory services, such as, White
   Pages.  Originally specified in the X.500 [X.500] documents, these
   objects are widely used as a basis for the schema in many LDAP
   directories.  This document does not cover attributes used for the
   administration of directory servers, nor does it include directory
   objects defined for specific uses in other documents.

1.1  Relationship with other specifications

   This document is an integral part of the LDAP technical specification
   [Roadmap] which obsoletes the previously defined LDAP technical
   specification, RFC 3377, in its entirety.  In terms of RFC 2256,
   Sections 6 and 8 of RFC 2256 are obsoleted by [Syntaxes].  Sections
   5.1, 5.2, 7.1 and 7.2 of RFC 2256 are obsoleted by [Models].  The
   remainder of RFC 2256 is obsoleted by this document.  Section 2.4 of
   this document supersedes the technical specification for the 'dc'
   attribute type and 'dcObject' object class found in RFC 2247.  The
   remainder of RFC 2247 remains in force.

   This document updates RFC 2798 by replacing the informative
   description of the 'uid' attribute type, with the definitive
   description provided in Section 2.39 of 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.  PKI-related schema elements are now specified in
   [LDAP-PKI].  Unless reintroduced in future technical specifications,
   the remainder are to be considered Historic.

   The descriptions in this document SHALL be considered definitive for
   use in LDAP.

1.2  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 RFC 2119 [RFC2119].

1.3  General Issues

   This document references Syntaxes defined in Section 3 of [Syntaxes]
   and Matching Rules defined in Section 4 of [Syntaxes].

   The definitions of Attribute Types and Object Classes are written

   using the Augmented Backus-Naur Form (ABNF) [RFC4234] of
   AttributeTypeDescription and ObjectClassDescription given in
   [Models].  Lines have been folded for readability.  When such values
   are transferred as attribute values in the LDAP Protocol the values
   will not contain line breaks.

2.  Attribute Types

   The Attribute Types contained in this section hold user information.

   There is no requirement that servers implement the 'searchGuide' and
   'teletexTerminalIdentifier' attribute types.  In fact, their use is
   greatly discouraged.

   An LDAP server implementation SHOULD recognize the rest of the
   attribute types described in this section.

2.1  'businessCategory'

   The 'businessCategory' attribute type describes the kinds of business
   performed by an organization.  Each kind is one value of this
   multi-valued attribute.
   (Source: X.520 [X.520])

      ( 2.5.4.15 NAME 'businessCategory'

         SUBSTR caseIgnoreSubstringsMatch

   1.3.6.1.4.1.1466.115.121.1.15 refers to the Directory String syntax
   [Syntaxes].

   Examples: "banking", "transportation" and "real estate".

2.2  'c'

   The 'c' ('countryName' in X.500) attribute type contains a two-letter
   ISO 3166 [ISO3166] country code.
   (Source: X.520 [X.520])

INTERNET-DRAFT     LDAP: Schema for User Applications   January 30, 2006


   Examples: "DE", "AU" and "FR".

2.3  'cn'

   The 'cn' ('commonName' in X.500) attribute type contains names of an
   object.  Each name is one value of this multi-valued attribute.  If
   the object corresponds to a person, it is typically the person's full
   name.
   (Source: X.520 [X.520])

      ( 2.5.4.3 NAME 'cn'
         SUP name )

   Examples: "Martin K Smith", "Marty Smith" and "printer12".

2.4  'dc'

   The 'dc' ('domainComponent' in RFC 2247) attribute type is a string
   holding one component, a label, of a DNS domain name [RFC1034].  The
   encoding of IA5String for use in LDAP is simply the characters of the
   ASCII label.  The equality matching rule is case insensitive, as is
   today's DNS.
   (Source: RFC 2247 [RFC2247])

      ( 0.9.2342.19200300.100.1.25 NAME 'dc'
         EQUALITY caseIgnoreIA5Match
         SUBSTR caseIgnoreIA5SubstringsMatch
         SYNTAX 1.3.6.1.4.1.1466.115.121.1.26
         SINGLE-VALUE )

   1.3.6.1.4.1.1466.115.121.1.26 refers to the IA5 String syntax
   [Syntaxes].

   Examples: Valid values include "example" and "com".  The value
             "example.com" is invalid, because it contains two label
             components.

   Directory applications supporting International Domain Names SHALL
   use the ToASCII method [RFC3490] to produce the domain name component
   label.  The special considerations discussed in section 4 of RFC 3490
   [RFC3490] should be taken, depending on whether the domain component
   is used for "stored" or "query" purposes.

2.5  'description'

   The 'description' attribute type contains human-readable descriptive
   phrases about the object.  Each description is one value of this
   multi-valued attribute.
   (Source: X.520 [X.520])

      ( 2.5.4.13 NAME 'description'
         EQUALITY caseIgnoreMatch
         SUBSTR caseIgnoreSubstringsMatch
         SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )

   1.3.6.1.4.1.1466.115.121.1.15 refers to the Directory String syntax
   [Syntaxes].

   Examples: "a color printer", "Maintenance is done every Monday, at
             1pm." and "distribution list for all technical staff".

2.6  'destinationIndicator'

   The 'destinationIndicator' attribute type contains country and city
   strings, associated with the object (the addressee), needed to
   provide the Public Telegram Service.  The strings are composed in
   accordance with CCITT Recommendations F.1 [F.1] and F.31 [F.31].
   Each string is one value of this multi-valued attribute.
   (Source: X.520 [X.520])

      ( 2.5.4.27 NAME 'destinationIndicator'
         EQUALITY caseIgnoreMatch
         SUBSTR caseIgnoreSubstringsMatch
         SYNTAX 1.3.6.1.4.1.1466.115.121.1.44 )

   1.3.6.1.4.1.1466.115.121.1.44 refers to the Printable String syntax
   [Syntaxes].

   Examples: "AASD" as a destination indicator for Sydney, Australia.
             "GBLD" as a destination indicator for London, United
             Kingdom.

   It is noted that the directory will not ensure that values of this
   attribute conform to the F.1 and F.30 CCITT Recommendations.  It is
   the application's responsibility to ensure destination indicators
   that it stores in this attribute are appropriately constructed.

2.7  'distinguishedName'

   The 'distinguishedName' attribute type is not used as the name of the
   object itself, but it is instead a base type from which some user

   attribute types with a DN syntax can inherit.

   It is unlikely that values of this type itself will occur in an
   entry.  LDAP server implementations which do not support attribute
   subtyping need not recognize this attribute in requests.  Client
   implementations MUST NOT assume that LDAP servers are capable of
   performing attribute subtyping.
   (Source: X.520 [X.520])

      ( 2.5.4.49 NAME 'distinguishedName'
         EQUALITY distinguishedNameMatch
         SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 )

   1.3.6.1.4.1.1466.115.121.1.12 refers to the DN syntax [Syntaxes].

2.8  'dnQualifier'

   The 'dnQualifier' attribute type contains disambiguating information
   strings to add to the relative distinguished name of an entry.  The
   information is intended for use when merging data from multiple
   sources in order to prevent conflicts between entries which would
   otherwise have the same name.  Each string is one value of this
   multi-valued attribute.  It is recommended that a value of the
   'dnQualifier' attribute be the same for all entries from a particular
   source.
   (Source: X.520 [X.520])

         EQUALITY caseIgnoreMatch

         SUBSTR caseIgnoreSubstringsMatch
         SYNTAX 1.3.6.1.4.1.1466.115.121.1.44 )

   1.3.6.1.4.1.1466.115.121.1.44 refers to the Printable String syntax
   [Syntaxes].

   Examples: "20050322123345Z" - timestamps can be used to disambiguate
             information.
             "123456A" - serial numbers can be used to disambiguate
             information.

2.9  'enhancedSearchGuide'

   The 'enhancedSearchGuide' attribute type contains sets of information
   for use by directory clients in constructing search filters.  Each
   set is one value of this multi-valued attribute.
   (Source: X.520 [X.520])

   unauthorized parties.

   An example of a need for multiple values in the 'userPassword'
   attribute is an environment where every month the user was expected
   to use a different password generated by some automated system.
   During transitional periods, like the last and first day of the
   periods, it may be necessary to allow two passwords for the two
   consecutive periods to be valid in the system.

2.42  'x121Address'

   The 'x121Address' attribute type contains data network addresses as
   defined by ITU Recommendation X.121 [X.121].  Each address is one
   value of this multi-valued attribute.

   [Syntaxes].

   Example: "36111222333444555".

2.43  'x500UniqueIdentifier'

   The 'x500UniqueIdentifier' attribute type contains binary strings
   that are used to distinguish between objects when a distinguished
   name has been reused.  Each string is one value of this multi-valued
   attribute.
   In X.520 [X.520], this attribute type is called 'uniqueIdentifier'.
   This is a different attribute type from both the 'uid' and
   'uniqueIdentifier' LDAP attribute types.  The 'uniqueIdentifier'
   attribute type is defined in [RFC1274].

5.  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 is strongly discouraged where the
   underlying transport service cannot guarantee confidentiality and
   integrity, since this may result in disclosure of the password to
   unauthorized parties.

   Multiple attribute values for the 'userPassword' attribute need to be
   used with care.  Especially reset/deletion of a password by an admin
   without knowing the old user password gets tricky or impossible if
   multiple values for different applications are present.

   Certainly, applications which intend to replace the 'userPassword'
   value(s) with new value(s) should use modify/replaceValues (or
   modify/deleteAttribute+addAttribute).  Additionally, server
   implementations are encouraged to provide administrative controls
   which, if enabled, restrict the 'userPassword' attribute to one
   value.

   Note that when used for authentication purposes [AuthMeth], the user
   need only prove knowledge of one of the values, not all of the
   values.

      30. Spelt out and referenced ABNF on first usage.

      31. Removed Section 2.4 (Source). Replaced the source table with
          explicit references for each definition.

      32. All references to an attribute type or object class are
          enclosed in single quotes.

      33. The layout of attribute type definitions has been changed to
          provide consistency throughout the document:
          > Section Heading
          > Description of Attribute type
          > Multivalued description
          > Source Information
          > Definition
          > Example

          include 'commonName', 'dcObject', 'domainComponent', 'GN',
          'localityName', 'organizationName', 'organizationUnitName',
          'surname', 'uidObject' and 'userid'.

      39. Renamed all instances of supercede to supersede.

      40. Moved [F.1], [F.30] and [SASLprep] from informative to
          normative references.

      41. Changed the 'c' definition to be consistent with X.500.

      42. Added text to 'dc', making the distinction between 'stored'
          and 'query' values when preparing IDN strings.
