FreeRADIUS time based authentication with MySQL

Hello ! Maybe somebody knows, how to configure FreeRADIUS server with my SQL for authentication at the specific time? For example: There is a reservation page. Users can reserve specific time slot, for 1-3hours. Random username and password would be generated for that user to log in at that time. How to configure freeradius server for this type of authentication? That user can log in just at that specific time? Thank you very much for your time and answers! -- View this message in context: http://freeradius.1045715.n5.nabble.com/FreeRADIUS-time-based-authentication...
