I am trying to transfer the conventional radius (use text file to record users) to Radiator system. I have several NAS devices including Cisco AS5300 and Xyplex Terminal Server in several location. Now I use central authentication for all users in different location. In conventional radius, it will keep several detail files according to the IP address of NAS device (for example, NAS1 will keep detail file in a directory a.b.c.d, NAS2 will keep detail file in a directory e.f.g.h) . If I want to use SQL server for authentication, accounting and billing, please give me some suggestions how do I to design database schema for accounting (according to date, NAS device,....) so that I can bill all users according their usage(time or packages).
