I am trying to setup Salesforce Communities as a SAML IdP for our application following the procedures here: https://developer.salesforce.com/page/Salesforce_IdP_Setup amongst other supporting documentation.
Our application currently expects the IdP (Salesforce) to initiate the SAML response to our application once the user has been redirected to Salesforce Login then completed Login. Does Salesforce support this?
Overall we are having trouble finding good documentation around setting up Salesforce as a SAML 2.0 IdP, most documentation focuses around having Salesforce as a Service Provider and setting up a separate application as a IdP. Is there any good documentation I am missing around this?
