User restrictions

Hello,

I want to be able to restrict some folder with user levels.
I have 3 userlevels on my website: admin, teacher and student. The admin level should be able to see all folders, teacher level should be able to see all the folders of its students and the students should only see their own folders.

Admin
- Teacher 1
--- Student 1
--- Student 2
--- Student 3
- Teacher 2
--- Student 1
--- Student 2
--- Student 3

How can I code this in CKFinder?
Thanks in advance.
