Is it possible? CoA disconnect packet communication between radius 3 and Unifi AP Clients

Hello, I am new to this mailing list. I will be brief, I need an AAA server over a network of Ubiquiti AP Unifi, I have to say that it was not difficult for me to install a freeradius 3.0.x server. My problem: But I can't disconnect devices, using CoA packets: echo User-Name = 'user' radclient 127.0.0.1:3799 disconnect testing123 I consult them: Someone managed to use the CoA disconnect packets between a freeradius 3.0.X server and AP's ubuquiti Unifi AP. I have read the ubiquiti forums without clear results. Greetings and thanks. -- Luis Gutierrez Cruz Movil: 71255832 Twitter: @LuisBPS
