INTERNET-DRAFT     LDAPv3: A Collection of User Schema     22 April 2001


1. Background and Intended Use

  This document provides descriptions [RFC2252] of user schema for use
  with LDAP [LDAPTS] collected from numerous sources.

  The document includes a summary of select schema introduced for the
  COSINE and Internet X.500 pilot projects [RFC1274].  This document
  obsoletes RFC 1274.

  The document also contains a summary of X.500 user schema [X.520] not
  included in LDAPv3 [RFC2256].

  The key words ``MUST'', ``MUST NOT'', ``REQUIRED'', ``SHALL'', ``SHALL
  NOT'', ``SHOULD'', ``SHOULD NOT'', ``RECOMMENDED'',  and ``MAY'' in
  this document are to be interpreted as described in RFC 2119
  [RFC2119].


2. Syntaxes

  None (yet).


3. Matching Rules

  This section introduces LDAP matching rules based upon descriptions of
  their X.500 counterparts.


3.1. caseExactMatch

  CaseExactMatch compares for equality the asserted string with an
  attribute value of DirectoryString syntax.  The rule is identical to
  the caseIgnoreMatch [RFC2252] rule except that case is not ignored.
  (Source: X.520)

      ( 2.5.13.5 NAME 'caseExactMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )


3.2. caseExactOrderingMatch

  CaseExactOrderingMatch compares the collation order of the asserted
  string with an attribute value of DirectoryString syntax.  The rule is
  identical to the caseIgnoreOrderingMatch [RFC2252] rule except that
  letters are not folded.  (Source: X.520)

      ( 2.5.13.6 NAME 'caseExactOrderingMatch'

        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )


3.3. caseExactSubstringsMatch

  CaseExactSubstringsMatch determines whether the asserted value is a
  substring of an attribute value of DirectoryString syntax.  The rule
  is identical to the caseIgnoreSubstringsMatch [RFC2252] rule except
  that case is not ignored.  (Source: X.520)

      ( 2.5.13.7 NAME 'caseExactSubstringsMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.58 )


3.4. numericStringOrderingMatch

  NumericStringOrderingMatch compares the collation order of the
  asserted string with an attribute value of NumericString syntax.  The
  rule is identical to the caseIgnoreOrderingMatch [RFC2252] rule except
  that all space characters are skipped during comparison (case is
  irrelevant as characters are numeric).  (Source: X.520)

      ( 2.5.13.9 NAME 'NumericStringOrderingMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.36 )


3.5. caseIgnoreListSubstringsMatch

  CaseIgnoreListSubstringMatch compares the asserted substring with an
  attribute value which is a sequence of DirectoryStrings, but where the
  case (upper or lower) is not significant for comparison purposes.  The
  asserted value matches a stored value if and only if the asserted
  value matches the string formed by concatenating the strings of the
  stored value. This matching is done according to the
  caseIgnoreSubstringsMatch [RFC2252] rule; however, none of the
  initial, any, or final values of the asserted value are considered to
  match a substring of the concatenated string which spans more than one
  of the strings of the stored value.  (Source:  X.520)

      ( 2.5.13.12 NAME 'caseIgnoreListSubstringsMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.58 )


3.6. storedPrefixMatch

  StoredPrefixMatch determines whether an attribute value, whose syntax
  is DirectoryString, is a prefix (i.e. initial substring) of the
  asserted value, without regard to the case (upper or lower) of the

  strings.  The rule returns TRUE if and only if the attribute value is
  an initial substring of the asserted value with corresponding
  characters identical except possibly with regard to case.  (Source:
  X.520)

      ( 2.5.13.41 NAME 'storedPrefixMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )

  Note: This rule can be used, for example, to compare values in the
        Directory which are telephone area codes with a purported value
        which is a telephone number.


3.7. booleanMatch

  BooleanMatch compares for equality a asserted Boolean value with an
  attribute value of BOOLEAN syntax.  The rule returns TRUE if and only
  if the values are the same, i.e. both are TRUE or both are FALSE.
  (Source: X.520)

      ( 2.5.13.13 NAME 'booleanMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 )


3.8. octetStringOrderingMatch

  OctetStringOrderingMatch compares the collation order of the asserted
  octet string with an attribute value of OCTET STRING syntax.  The rule
  compares octet strings from first octet to last octet, and from the
  most significant bit to the least significant bit within the octet.
  The first occurrence of a different bit determines the ordering of the
  strings. A zero bit precedes a one bit. If the strings are identical
  but contain different numbers of octets, the shorter string precedes
  the longer string.  (Source:  X.520)

      ( 2.5.13.18 NAME 'octetStringOrderingMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 )


3.9. directoryStringFirstComponentMatch

  DirectoryStringFirstComponentMatch compares for equality the asserted
  DirectoryString value with an attribute value of type SEQUENCE whose
  first component is mandatory and of type DirectoryString.  The rule
  returns TRUE if and only if the attribute value has a first component
  whose value matches the asserted DirectoryString using the rules of
  caseIgnoreMatch [RFC2252].  A value of the assertion syntax is derived
  from a value of the attribute syntax by using the value of the first

  component of the SEQUENCE.  (Source: X.520)

        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )

3.10. wordMatch

  The wordMatch rule compares the asserted string with words in an
  attribute value of DirectoryString syntax.  The rule returns TRUE if
  and only if the asserted word matches any word in the attribute value.
  Individual word matching is as for the caseIgnoreMatch [RFC2252]
  matching rule. The precise definition of a "word" is implementation
  specific.  (Source: X.520)

      ( 2.5.13.32 NAME 'wordMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )


3.11. keywordMatch

  The keywordMatch rule compares the asserted string with keywords in an
  attribute value of DirectoryString syntax.  The rule returns TRUE if
  and only if the asserted value matches any keyword in the attribute
  value.  The identification of keywords in an attribute value and of
  the exactness of match are both implementation specific.  (Source:
  X.520)

      ( 2.5.13.32 NAME 'keywordMatch'
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )

5.5.  friendlyCountry

  The friendlyCountry object class is used to define country entries in
  the DIT.  The object class is used to allow friendlier naming of
  countries than that allowed by the object class country.  The naming
  attribute of object class country, c (countryName), has to be a 2
  letter string defined in [ISO3166].  (Source: RFC 1274)

      ( 0.9.2342.19200300.100.4.18

          MUST co )


5.6.  rFC822LocalPart

  The rFC822LocalPart object class is used to define entries which
  represent the local part of RFC822 mail addresses.  This treats this
  part of an RFC822 address as a domain [RFC2247].  (Source: RFC 1274)

              seeAlso $ telephoneNumber ) )


5.8.  simpleSecurityObject

  The simpleSecurityObject object class is used to allow an entry to
  have a userPassword attribute when an entry's principal object classes
  do not allow userPassword as an attribute type.  (Source: RFC 1274)

        mechanisms in LDAP are discussed in RFC 2829 [RFC2829].
