SAML 1.x profiles

SAML 1.0 and 1.1 profiles provide for browser-based single sign-on (SSO), initiated by an identity provider (IdP), using either the POST or artifact bindings.

The SAML 1.x specifications provide for a non-normative service provider (SP)-initiated scenario called “destination-first.” This scenario lets web developers create applications that enable a user to initiate SSO from the SP site.
