/**
 * The Server Authentication Context is an extra (required) indirection between the Application Server and the actual Server
 * Authentication Module (SAM). This can be used to encapsulate any number of SAMs and either select one at run-time, invoke
 * them all in order, etc.
 * 
 * Since this simple example only has a single SAM, we delegate directly to that one. Note that this {@link ServerAuthContext}
 * and the {@link ServerAuthModule} (SAM) share a common base interface: {@link ServerAuth}.
