+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
+   [RFC4510], 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 [RFC4517].  Sections
+   5.1, 5.2, 7.1, and 7.2 of RFC 2256 are obsoleted by [RFC4512].  The
+   remainder of RFC 2256 is obsoleted by this document.  The technical
+   specification for the 'dc' attribute type and 'dcObject' object class
+   found in RFC 2247 are superseded by sections 2.4 and 3.3 of this
+   document.  The remainder of RFC 2247 remains in force.

+RFC 4519           LDAP: Schema for User Applications          June 2006
+
+
+   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.
+
+   This document updates RFC 2377 by replacing the informative
+   description of the 'uidObject' object class with the definitive
+   description provided in Section 3.14 of this document.
+
+   A number of schema elements that 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
+   [RFC4523].  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 [RFC4517]
+   and Matching Rules defined in Section 4 of [RFC4517].
+
+   The definitions of Attribute Types and Object Classes are written
+   using the Augmented Backus-Naur Form (ABNF) [RFC4234] of
+   AttributeTypeDescription and ObjectClassDescription given in
+   [RFC4512].  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.

+RFC 4519           LDAP: Schema for User Applications          June 2006
+
+
+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'
+         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
+   [RFC4517].
+
+   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])
+
+      ( 2.5.4.6 NAME 'c'
+         SUP name
+         SYNTAX 1.3.6.1.4.1.1466.115.121.1.11
+         SINGLE-VALUE )
+
+   1.3.6.1.4.1.1466.115.121.1.11 refers to the Country String syntax
+   [RFC4517].
+
+   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 1274) attribute type is a string
+   holding one component, a label, of a DNS domain name
+   [RFC1034][RFC2181] naming a host [RFC1123].  That is, a value of this
+   attribute is a string of ASCII characters adhering to the following
+   ABNF [RFC4234]:
+
+   label = (ALPHA / DIGIT) [*61(ALPHA / DIGIT / HYPHEN) (ALPHA / DIGIT)]
+   ALPHA   = %x41-5A / %x61-7A     ; "A"-"Z" / "a"-"z"
+   DIGIT   = %x30-39               ; "0"-"9"
+   HYPHEN  = %x2D                  ; hyphen ("-")
+
+   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] and RFC 1274 [RFC 1274])
+
+      ( 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
+   [RFC4517].
+
+   Examples: Valid values include "example" and "com" but not
+   "example.com".  The latter is invalid as it contains multiple domain
+   components.
+
+   It is noted that the directory service will not ensure that values of
+   this attribute conform to the host label restrictions [RFC1123]
+   illustrated by the <label> production provided above.  It is the
+   directory client's responsibility to ensure that the labels it stores
+   in this attribute are appropriately restricted.
+
+   Directory applications supporting International Domain Names SHALL
+   use the ToASCII method [RFC3490] to produce the domain 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])

+
+   1.3.6.1.4.1.1466.115.121.1.15 refers to the Directory String syntax
+   [RFC4517].
+
+   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
+   [RFC4517].
+
+   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.31 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 that 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.

+
+   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 that would
+   otherwise have the same name.  Each string is one value of this

+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
+   administrator without knowing the old user password gets tricky or
+   impossible if multiple values for different applications are present.
+
+   Certainly, applications that intend to replace the 'userPassword'
+   value(s) with new value(s) should use modify/replaceValues (or
+   modify/deleteAttribute+addAttribute).  In addition, server
+   implementations are encouraged to provide administrative controls
+   that, if enabled, restrict the 'userPassword' attribute to one value.
+
+   Note that when used for authentication purposes [RFC4513], the user
+   need only prove knowledge of one of the values, not all of the
+   values.

+
+
+Appendix A.  Changes Made Since RFC 2256
+
+   This appendix lists the changes that have been made from RFC 2256 to

+          classes in favor of a statement in [RFC4517].
+
+      6.  Added explanation to attribute types and to each object class.
+
+      7.  Removed Section 4, Syntaxes, and Section 6, Matching Rules,
+          (moved to [RFC4517]).
+
+      8.  Removed the certificate-related attribute types:
+          authorityRevocationList, cACertificate,
+          certificateRevocationList, crossCertificatePair,
+          deltaRevocationList, supportedAlgorithms, and userCertificate.
+
+          Removed the certificate-related Object Classes:
+          certificationAuthority, certificationAuthority-V2,
+          cRLDistributionPoint, strongAuthenticationUser, and
+          userSecurityInformation
+
+          LDAP PKI is now discussed in [RFC4523].
+
+      9.  Removed the dmdName, knowledgeInformation,
+          presentationAddress, protocolInformation, and
+          supportedApplicationContext attribute types and the dmd,
+          applicationEntity, and dSA object classes.
+
+      10. Deleted the aliasedObjectName and objectClass attribute type
+          definitions.  Deleted the alias and top object class
+          definitions.  They are included in [RFC4512].

+RFC 4519           LDAP: Schema for User Applications          June 2006
+
+
+      11. Added the 'dc' attribute type from RFC 2247, making the
+          distinction between 'stored' and 'query' values when preparing
+          IDN strings.
+
+      12. Numerous editorial changes.
+
+      13. Removed upper bound after the SYNTAX oid in all attribute
+          definitions where it appeared.
+
+      14. Added text about Unicode, SASLprep [RFC4013], and UTF-8 for
+          userPassword.
+
+      15. Included definitions, comments and references for 'dcObject'
+          and 'uidObject'.
+
+      16. Replaced PKI schema references to use RFC 4523.
+
+      17. Spelt out and referenced ABNF on first usage.
+
+      18. Removed Section 2.4 (Source).  Replaced the source table with
+          explicit references for each definition.
+
+      19. All references to an attribute type or object class are
+          enclosed in single quotes.
+
+      20. 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
+          > Additional Comments
+
+          Adding this consistent output included the addition of
+          examples to some definitions.
+
+      21. References to alternate names for attributes types are
+          provided with a reference to where they were originally
+          specified.
+
+      22. Clarification of the description of 'distinguishedName' and
+          'name', in regards to these attribute types being supertypes.
+
+      23. Spelt out ISDN on first usage.
