SAML is an XML-based markup language for security assertions (statements that service providers use to make access-control decisions). SAML is also: A set of XML-based protocol messages; A set of protocol message bindings; A set of profiles (utilizing all of the above) An important use case that SAML addresses is web-browser single sign-on (SSO).
