Access Manager uses the Security Assertion Markup Language (SAML), an XML based framework for exchanging security information. While Access Manager User Session service enables single sign-on sessions among different DNS domains within the same intranet, SAML service enables cross-domain sign-on (CDSSO) sessions among different business domains. Using the SAML protocol, business partners can securely exchange authentication and authorization information over the Internet. Access Manager SAML service consists of a web service interface, a SAML core component, and a SAML framework that web services can connect to.
