/**
 * In these test cases, a CXF client requests a Security Token from an STS, passing a username that
 * it has obtained from an unknown client as an "OnBehalfOf" element. This username is obtained
 * by parsing the SecurityConstants.USERNAME property. The client then invokes on the service
 * provider using the returned (custom BinarySecurityToken) token from the STS.
 *
 * In the first test-case, the service provider dispatches the received BinarySecurityToken to the STS
 * for validation, and receives a transformed SAML Token in response. In the second test-case, the
 * service just validates the Token locally.
