The WS-Transfer: Identity Management Operations for Directory Access Extensions (henceforth referred to as "IMDA") are a set of extensions to the WS-Transfer protocol [WXFR] for representing the protocol operations commonly used for directory access in identity management protocols.
The goal of this specification is to enable identity management client applications, which are currently using non-Web service protocols such as Lightweight Directory Access Protocol (LDAP) v3 [RFC2251] for managing information held in directory services, to instead use Web service protocols.
This protocol extension is designed to layer atop the WS-Transfer protocol and to be composable with the WS-Management protocol [WSMAN].
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.
