RFC 3672                   Subentries in LDAP              December 2003


   In absence of the subentries control (detailed in Section 3),
   subentries SHALL NOT be considered in one-level and subtree scope
   search operations.  For all other operations, including base scope
   search operations, subentries SHALL be considered.

1.1.  Conventions

   Schema definitions are provided using LDAP description formats
   [RFC 2252].  Definitions provided here are formatted (line wrapped)
   for readability.

   Protocol elements are described using ASN.1 [X.680].  The term "BER-
   encoded" means the element is to be encoded using the Basic Encoding
   Rules [X.690] under the restrictions detailed in Section 5.1 of
   [RFC 2251].

   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 BCP 14 [RFC 2119].

2.  Subentry Schema

2.1.  Subtree Specification Syntax

   The Subtree Specification syntax provides a general purpose mechanism
   for the specification of a subset of entries in a subtree of the
   Directory Information Tree (DIT).  A subtree begins at some base
   entry and includes the subordinates of that entry down to some
   identified lower boundary, possibly extending to the leaf entries.  A
   subtree specification is always used within a context or scope which
   implicitly determines the bounds of the subtree.  For example, the
   scope of a subtree specification for a subschema administrative area
   does not include the subtrees of any subordinate administrative point
   entries for subschema administration.  Where a subtree specification
   does not identify a contiguous subset of the entries within a single
   subtree the collection is termed a subtree refinement.

   This syntax corresponds to the SubtreeSpecification ASN.1 type
   described in [X.501], Section 11.3.  This ASN.1 data type definition
   is reproduced here for completeness.

     SubtreeSpecification ::= SEQUENCE {
         base                [0] LocalName DEFAULT { },
                                 COMPONENTS OF ChopSpecification,
         specificationFilter [4] Refinement OPTIONAL }

     LocalName ::= RDNSequence
