/**
 * In this test case, a CXF client sends a Username Token via (1-way) TLS to a STS instance, and
 * receives a (HOK) SAML 1.1 Assertion. This is then sent via (1-way) TLS to an Intermediary
 * service provider. The intermediary service provider validates the token, and then the
 * Intermediary client uses delegation to dispatch the received token (via OnBehalfOf) to another
 * STS instance. After this point, the STSClient is disabled, meaning that the Intermediary client must rely
 * on its cache to get tokens. The retrieved token is sent to the service provider via (2-way) TLS.
