			if (in_array('admin', $identity->roles)) {

		}
		$this->terminate();
	}



	public function actionDownloadDump($host, $username, $password, $db)
	{
		try {
			$dump = $this->dbSynchronizer->dump($host, $username, $password, $db);
			$fileResponse = new FileResponse($dump, 'dump.sql', 'application/sql', TRUE);
			$this->presenter->sendResponse($fileResponse);
		} catch (\Exception $e) {
			Debugger::log($e, Base::LOG_DIRECTORY_NAME);
			header("HTTP/1.0 404 Not Found");
