IdP Initiated SSO

There's no such thing as unsolicited SSO. There are always requests. Some requests are SAML conformant and generated by an SP and some are proprietary and are just redirects or links on a web page. Some are digitally signed and some aren't.

Unsolicited SSO is just a proprietary, unsigned request protocol.
