SAML (Security Assertion Markup Language) is an OASIS standard developed to provide an XML-based method for communciating authentication and authorization data between domains inside and organization or betwen organizations. A SAML assertion or artifcat is issued by an identity provider to a principal (most often an end user). That assertion is subsequently provided to a service provider as a proof of authentication and/or authorization so the user gains the benefit of single sign on.
