Abstract

This document defines and describes the IntermediateResponse message, a general mechanism for defining single-request/multiple-response operations in Lightweight Directory Access Protocol (LDAP). The IntermediateResponse message is defined in such a way that the protocol behavior of existing LDAP operations is maintained. This message is intended to be used in conjunction with the LDAP ExtendedRequest and ExtendedResponse to define new single- request/multiple-response operations or in conjunction with a control when extending existing LDAP operations in a way that requires them to return intermediate response information.

1.  Introduction

   The Lightweight Directory Access Protocol (LDAP), version 3 [RFC3377]

   is an extensible protocol.  Extended operations ([RFC2251] Section

   4.12) are defined to allow for the addition of operations to LDAP,

   without requiring revisions of the protocol.  Similarly, controls

   ([RFC2251] Section 4.1.12) are defined to extend or modify the

   behavior of existing LDAP operations.

   LDAP is a client-request/server-response based protocol.  With the

   exception of the search operation, the entire response to an

   operation request is returned in a single protocol data unit (i.e.,

   LDAP message).  While this single-request/single-response paradigm is

   sufficient for many operations (including all but one of those

   currently defined by [RFC3377]), both intuition and practical

   experience validate the notion that it is insufficient for others.
