This document specifies the WS-Transfer and WS-Enumeration Protocol Extension for Lightweight Directory Access Protocol v3 Controls, also known as WSPELD. WSPELD extends the Web Services Enumeration (WS-Enumeration) [WSENUM] and Web Services Transfer (WS-Transfer) [WXFR] Protocols. The WSPELD specification specifically targets directory servers exposing semantics similar to LDAP v3 [RFC2251].
WSPELD extensions to the SOAP-based Enumeration and Transfer protocol include the support for sending and receiving LDAP v3 request and response controls, respectively, while retrieving, querying, and modifying objects or object fragments stored in the directory server through SOAP messages. These extensions act as a controlling factor and influence the operation’s behavior implemented using the preceding protocols in a manner specific to the control [RFC2251].
This document also describes how WSPELD extensions need to be used in conjunction with the WS-Transfer: Identity Management Operations for Directory Access Extensions [MS-WSTIM] of Web Services Transfer (WS-Transfer).
Sections 1.8, 2, and 3 of this specification are normative and can contain the terms MAY, SHOULD, MUST, MUST NOT, and SHOULD NOT as defined in [RFC2119]. Sections 1.5 and 1.9 are also normative but do not contain those terms. All other sections and examples in this specification are informative.
