PHP under ASP.NET MVC security

I want to do this same as mentioned here aspnet membership for zend php but, the ASP.NET should be the main credential controler - not PHP.

My scenario is that we have already developed ASP.NET MVC CRM and now want to add file explorer. We choosen http://www.ajaxplorer.info/, but it is PHP application. So there is a security issue: Some could get access to the files without singing in. How to prevent this?

Or maybe yo开发者_如何学Pythonu know asp mvc file manager? We know IZWebFileManager and Telerik FileManager, but they have to poor funcionality.

An alternative file manager that works with asp.net is CKFinder
