What is SAML 2.0 ?

Why do you need SAML 2.0 ?

SAML 2.0 enables identity propagation of an authenticated user between a company’s identity provider and a third-party service. It is needed for integrating an enterprise’s existing single sign-on (SSO) with third-party ( cloud based) service providers. Thus authentication can be performed with the company’s own identity provider. Its

employees/partners (or authenticated users) are required to authenticate only once to a web site but can subsequently log-in to many services without having to re-type there passwords again.
