All Implemented Interfaces:

SAMLMessageDecoder, MessageDecoder

public class UnsolicitedSSODecoder
extends BaseSAML2MessageDecoder
implements SAMLMessageDecoder

Shibboleth 2.x HTTP request parameter-based SSO authentication request message decoder.

This decoder understands and processes a set of defined HTTP request parameters representing a logical SAML 2 SSO authentication request, and builds a corresponding AuthnRequest message. This message is then stored in the SAMLMessageContext so that it may be processed by other components (e.g. profile handler) that process standard AuthnRequest messages.
