[keycloak-dev] Details on SAML Soap Binding support in Keycloak

We have a requirement to setup a SAML SP that sends SOAP request to the keycloak IDP which returns the SOAP response to the SAML SP. We would like to know if keycloak supports this? We came across something called as ECP that probably provides this support but cant find details on how to use/implement it. Could you provide us with some pointers on this? Also, are there any sample SP that we can use to send SOAP requests to IDP? If not, any pointers on how to set this all up?
