Abstract
The Infinite Talent SSO solution supports the SAML 2.0 specification; therefore the IdP needs to provide assertions using SAML 2.0.
This means that the IdP must be able to accept authentication requests so that the principal, or an agent acting on behalf of the principal, can request assertions containing authentication statements. The web browser SSO profile uses the authentication request protocol when redirecting a user from a SP to an IdP when it needs to obtain an assertion in order to establish a security context for the user at the SP.
