    ****************************************************************
    Security Assertion Markup Language (SAML) is an OASIS open
    standard for representing and exchanging user identity,
    authentication, and attribute information. SAML is fast
    becoming
    the technology of choice to provide cross-vendor single sign-on
    (SSO) interoperability.
    SAML 2.0 Web Browser SSO Profile is defined to support web
    single sign-on.
    Exerpt from "Profiles for the OASIS Security
    Assertion Markup Language (SAML) V2.0", OASIS Standard, 15
    March 2005:
    "In the scenario supported by the web browser SSO profile, a
    web user either accesses a resource at a service provider,
    or accesses an identity provider such that the service
    provider and desired resource are understood or implicit. The
    web user authenticates to an identity provider, which then
    produces an authentication assertion, and the service provider
    consumes the assertion to establish a security context for the
    web user."
    

Problem conclusion

  • This APAR adds new function to WebSphere Application Server to
    support IdP initiated SAML web SSO.
    
    The WebSphere Application Server SAML service provider (SP)
    supports SAML 2.0 Identity Provider (IdP) initiated single
    sign-on (SSO). WebSphere IdP initiated SSO service is
    implemented as a Trust Association Interceptor (TAI) and the
    sequence flow can be decribed as follows:
    
       1. A user accesses a front end web application that can
    reside on an IdP, SP, or elsewhere.
       2. A front-end web application redirects the user to the IdP
    and the user authenticates to the IdP.
       3. The IdP redirects the user to the Assertion Consumer
    Service (ACS) in the SP by sending a SAML response over an HTTP
    POST inside a hidden form.
       4. The SP processes the SAML response and creates a
    WebSphere security context.
       5. The SP adds an LTPA cookie to HTTP response and
    redirects the HTTP request to a web resource or business
    application.
       6. The WebSphere Application Server intercepts the request,
    and maps the LTPA cookie to a security context and authorizes
    the user to access the requested web resource.
       7. The WebSphere Application Server sends an HTTP response
    back to the user.
    
    Highlights of the SAML Web SSO feature:
    
        * The WebSphere SAML service provider supports single
    sign-on with multiple identity providers.
        * The WebSphere SAML service provider supports options for
    identity assertion and mapping the assertion identity to the
    user registry of the service provider.
        * The WebSphere SAML service provider provides a plug
    point to allow for customized identity mapping.
        * The WebSphere SAML service provider preserves the SAML
    token in the subject of the service provider for access by the
    application, and makes it available for a downstream
    authenticated Enterprise JavaBean (EJB) or Web Service call.
        * The WebSphere SAML service provider allows a business
    application URL to act as an AssertionConsumerService URL, so
    the IdP can send a SAMLResponse directly to the business
    application URL.
        * The WebSphere SAML TAI allows auditing of key SAML
    assertions, including Issuer and NameID.
    
    More information about about the WebSphere SAML 2.0 Web Browser
    SSO feature can be found in the Information center.
    
    Due to the large size of this update, it will only be
    available via a fix pack; interim fixes cannot be created.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.23 and 8.0.0.4.  Please refer to the
