KoolReport is sole framework for reporting so it does not have user management capability. You may use KoolReport together with Laravel because Laravel provide user authentication.

KoolReport focuses only on creating report so you can do the user management by yourself and then base on user role, you generate correct report for the role. KoolReport can received parameters so you can transmit the user information as report parameters and based on those information, you can expose authorized information in report.

Let say you create a report inside each action of laravel's controller. By this way, you can apply the auth for each action. As a result, it will transform to auth for each reports. Hope my answer helps.
