limiting user access by day

Hi all, I'm currently setup freeradius server for hotspot, but right now I have some problem for limiting access user to particular day. As example : user1 accessing on Monday to Friday and user2 only accesing on Saturday or Sunday. And each user is limiting for one day access only, and after that day he/she can't login again. Is there any module or attribute to setup radius for this system. Any help would be appreciated. Thank you Budiono
