[keycloak-user] Salesforce as an SP with SAML

I am trying to setup SSO into Salesforce using SAML. I tried to insert an IDP initiated SSO URL as https://myserveraddress/auth/realms/web/protocol/saml/clients/salesforce-..., the last part being the ClientID but that too does not work. I get an error on the server that the client is not found. Server is running 1.5.0.Final. Has anyone successfully integrated SF? What do I need the address to be?
