Hello, I need a command to api or ... that could use in my program to disconnect user based that user session id. [assume two user with same username connected [with radius authentication] and I want disconnect just one of them] how can I do it with command line?

Hi, It seems that there is no command to disconnect a VPN connection according to user session ID. However you can restrict only one VPN connection per user by writing a RAS administration DLL for this purpose.
