Allow cusomer to review his connection.

Hi there is any way to allow a customer to review all connection made to his devices?
We try to find a solution in that way:
We have created a folder for every customer, and in management console, we have created a user with access to his shared folder. This is working well except this user have also access to "All" folder, where is stored all connections we do to every client and the parter id of all.

And either this user have also a channel associated to it.  

Anyone have any Idea how to create a customer user only for review?

Thanks
