/**
 * The client authenticates to the STS using a username/password, and gets a signed holder-of-key 
 * SAML Assertion in return. This is presented to the service, who verifies proof-of-possession + 
 * the signature of the STS on the assertion. The CXF endpoint extracts roles from the Assertion + 
 * populates the security context. Note that the CXF endpoint requires a "role" Claim via the
 * security policy.
 *
 * The CXF Endpoint has configured the XACMLAuthorizingInterceptor, which creates a XACML 2.0 request 
 * for dispatch to the PDP, and then enforces the PDP's decision. The mocked PDP is a REST service, 
 * that requires that a user must have role "boss" to access the "doubleIt" operation ("alice" has 
 * this role, "bob" does not).
