This protocol specification describes the X.509 Certificate Enrollment Policy Protocol, a protocol between a requesting client and a responding server for the exchange of a certificate enrollment policy.
The communication is initiated by a requesting client that requests either the full certificate enrollment policy, or a subset, by passing in a filter. A server processes the identity of the client and an optionally provided client filter, and generates a response with a collection of certificate enrollment policy objects accompanied by a collection of certificate issuers. The returned certificate issuers provide X509v3 Security Token issuance using [MS-WSTEP].
The X.509 Certificate Enrollment Policy Protocol is a minimal messaging protocol that includes a single client request message (GetPolicies) with a matching server response message (GetPoliciesResponse). The server can alternatively respond with a SOAP fault message.
Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
