Agenda Introduction SAML Concepts Liferay and SAML 2.0 Demo

What is SAML? Security Assertion Markup Language XML based protocol OASIS approved standard SAML 1.0 November 2002 SAML 1.1 September 2003 SAML 2.0 March 2005 Flexible and extensible protocol designed to be used by other standards

SAML Roles Identity Provider (IdP) / Asserting party Service Provider (SP) / Relying party User

SAML Concepts

Protocols Authentication Request Protocol Assertion Query and Request Protocol Artifact Resolution Protocol Name Identifier Management Protocol Name Identifier Mapping Protocol Single Logout Protocol

Bindings HTTP Redirect Binding HTTP Post Binding HTTP Artifact Binding SAML SOAP Binding Reverse SOAP (PAOS) Binding SAML URI Binding

Profiles Web Browser SSO Profile Enhanced Client and Proxy (ECP) Profile Identity Provider Discovery Profile Single Logout Profile Assertion Query/Request Profile Artifact Resolution Profile Name Identifier Management Profile Name Identifier Mapping Profile

Liferay and SAML 2.0 Available as a EE plugin Supports two operation modes Identity Provider Service Provider Built on top of OpenSAML Uses Java keystore for credentials Configured using SAML metadata and portal(- ext).properties

Features IdP initiated Web SSO SP initiated Web SSO SP initiated Single Logout IdP initiated Single Logout Consumes and Produces SAML Metadata Attribute statement generation (IdP) JIT provisioning using attribute statements (SP)

IdP Supported Bindings Web Single Sign-On Profile HTTP Redirect Binding (AuthnRequest) HTTP Post Binding (AuthnRequest and Response) Single Logout Profile HTTP Redirect Binding (SP initiated only) SAML SOAP Binding (IdP to SP only)

SP Supported Bindings Web Single Sign-On Profile HTTP Redirect Binding (AuthnRequest) HTTP Post Binding (Response) Single Logout Profile HTTP Redirect Binding (SP initiated only) SAML SOAP Binding (IdP to SP only)
