Again, I'm a relatively new freeradius user so I am not really an expert with it. In our project, we need to "add" and "delete" users from the server database from an authorized client computer. And we're a little confused on how adding and removing users work. When the client makes a request to add a user in the database, does it simply ask access in the mysql backend of the server, or make the request to the server first, and the server itself will "request" its database backend to add the user? How exactly do we request an addition or deletion of a user? Do we use the simple sql queries in the radcheck table? By the way, we've already configured the server to allow access from this client computer in the clients.conf file. We've tested it using radtest in it receives an access-accept packet. Our installed version is 2.1.0+dfsg-0ubuntu2, running on Ubuntu 8.10. The backend database we used is MySql. Thanks in advance. -- Joeven Rex L.
