Hi Developers, Due to the inconvenience of the Anyconnect Client(cannot save user name and password), users urged the admin to distribute certificates. However even Certificate Auth. and Radius accounting can be combined and work well with each other on the latest ocserv, the Radius sever can do nothing to restrict a client once beyond the monthly or daily volume threshold of its account. Could you give me some pointers to meet these demands? As I read from the manual, the ocserv just send several attributes to the radius server. Thank you for your read and looking forward to your reply. Regards, Yick
