How can I use FreeRadius and MySql to response respectively to the  different users? 

   I need to give different permissons or rights to the logined uses.Should I maintain a table that map detailed permission to different uses? How to write the program which handle the tables?

  Btw, I want to use AES  cryptographic algorithm  to  encrypt the user's password or ID, and store  the encrypted results on the FreeRadius Server machine .How can I give different authorizations to different users according to their AES encypted password?

  Should I write EAP program?

  Thanks  in advance.
