/**
 * Thrown only when a "bind" attempt fails and a BaseBindResp was returned.
 * This exception can only be created from the BaseBindResp instance which is
 * used to create the error message as well.
 * 

 * If no BindResp was received and we timed out while waiting, then an
 * SmppTimeoutException or SmppConnectionException would have occurred, not this
 * specific error.  The underlying status code and mapped message can be figured
 * out as well.
