Within the Shibboleth System, the SP includes support for ECP (both basic and delegated variants). The IdP supports extensions that provide the basic and delegated variants. Since IdP 2.3, the basic variant is part of the core. The version included with IdP 2.4 includes some of the new 2.0 features added to the profile.
