Can you explain the difference between IdP and SP-initiated SSO in SAML?

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 IdP-initiated sign on page?

The AD FS sign-on page can be used to test whether or not authentication is working. This is done by navigating to the page and signing in. Also, we can use the sign-in page to verify that all SAML 2.0 relying parties are listed.

What is difference between SP and IdP?

The IdP creates an SSO Response with a SAML 2.0 Assertion containing user information as well as authentication data, and redirects the user’s browser to the SP with the message and the RelayState parameter. The SP validates the SAML 2.0 Assertion and creates an SSO session for the user.

What is SP initiated single sign on?

Service Provider (SP) initiated SSO involves the SP creating a SAML request, forwarding the user and the request to the Identity Provider (IdP), and then, once the user has authenticated, receiving a SAML response & assertion from the IdP.

If all user interaction with the service provider’s application will start at a “homepage”, or default landing page, then IdP-initiated probably makes a lot of sense (less to break – no signed AuthnRequest needed).

Where do I find IdP initiated SSO in Procore?

Identity Provider Initiated (IdP-initiated) SSO. With this option, your end users must log into your Identity Provider’s SSO page (e.g., Okta, OneLogin, or Microsoft Azure AD) and then click an icon to log into and open the Procore web application.
