Single Sign-On Introduction

In this IdP-Initiated SSO scenario, a user logs on to the IdP site and attempts to access a resource on the SP site.

Processing Steps:

  1. A user browse to the IdP site
  2. The IdP site will ask the user to provide his/her credentials if he or she is not logged in
  3. After the user has logged in, he or she clicks on a link/button to navigate to the SP site. (Some sites may navigate the users automatically)
  4. At this point, the IdP sends SAML Response containing the authentication assertion and any additional attributes to the SP's Assertion Consumer Service.
  5. The SP validates the message. If the signature and assertion are valid, the SP uses the information in the SAML Response to perform an automatic login.

Single Logout Introduction

In this IdP-Initiated SLO scenario, a user clicks on a link at the IdP site to log out of the IdP site and all the participating SP sites.
