Hello,

I am trying to setup SSO with a third party vendor. They only accept IDP initiated SSO. So when I setup their client in Keycloak, I am having a hard time figure out what the URL I will need to use to be able to authenticate into their application.  
Ive following these examples with no luck:

> The following steps describe how to set up KeyCloak as an identity provider in a service-initiated SAML SSO login scenario for the HTTP browser profile.

Can anyone provide some insight?
