integrate with phpmaker 9

Hello

We have a customer request to use the advanced security user level of phpmaker 9 (hkvstore.com) with DHTMLX. So that the customer can manage the access right onto table and record level.
The customer says that DHTML has no security controll.
An integration is possible? What whould you suggest to check if the logged user has the right to add, delete, edit etc…

thanks
