What is the difference between SP initiated and IdP initiated SSO?

In IDP Init SSO (Unsolicited Web SSO) the Federation process is initiated by the IDP sending an unsolicited SAML Response to the SP. In SP-Init, the SP generates an AuthnRequest that is sent to the IDP as the first step in the Federation process and the IDP then responds with a SAML Response.

What is delegated authentication in Salesforce?

The SSO Server determines that the user should be authenticated via Federation SSO, selects an IdP, creates a SAML 2.0 AuthnRequest message, saves the operational state in the SSO server store and redirects the user’s browser to the IdP with the SAML message and a string referencing the operational state at the SP
