/**
 * This is a series of tests of the distributed caching abilities of the STS. In these test-cases,
 * a CXF client invokes on an STS and obtains a security token, which is sent to a service provider.
 * The service provider is configured to validate the received token against a second STS instance.
 * Both STS instances must have a shared distributed cache, and enough time must have elapsed for
 * the first STS instance to replicate the credential to the second STS instance for the test to 
 * work.
