title: Confuse about service provider in spring security saml
body: <p>I am learning how to implement single sign on by using spring security saml for my school assignment. I want to implement SSO function that when I login to one application, there is no need to login to other applications. I have walked through the quick start example and read through the whole document. But still have no clue how to map a spring service provider to several different applications. DO I need to configure each web application as an individual service provider? Or create one web application acting as the only service provider then map it to several applications? Any help will be so grateful.   </p>
