The WS-Enumeration Directory Services Protocol Extensions [MS-WSDS] are a set of extensions to the Web Services Enumeration (WS-Enumeration) [WSENUM] protocol for facilitating SOAP-based search operations against directory servers. This protocol makes it easy for client applications that currently use non-Web services protocols, such as Lightweight Directory Access Protocol (LDAP) version 3 [RFC2251], to instead use Web service protocols for such operations.
The extensions to the SOAP-based Enumeration protocol specify dialect for expressing the search filter for an enumeration. It also provide a means of requesting and receiving selected fragments of resultant objects in the context of a specific enumeration and an additional set of SOAP faults for various WS-Enumeration [WSENUM] operations.
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 RFC 2119. Sections 1.5 and 1.9 are also normative but cannot contain those terms. All other sections and examples in this specification are informative.
