/**
* In the event that a left-over TGT exists from previous session, from which

* invalid, this exception will be thrown.
*<p>
* In particular, the flow is to handle this exception and navigate to the
* appropriate state, without requiring any additional action from the user
* such as closing the browser to clearing the cache thereby killing the TGT.
* The flow is responsible for handling this annoyance.
*
* <p>Essentially, the responsibility of this exception is solely to
* communicate a broken and existing TGT, or in other words, the inability
* to construct the authentication object from either the flow context
* or an existing TGT. Beyond that task, it will not do
* or provide any interesting functionality.
