SSID check

Hello, I want to Allow an user to connect freeradius only if the SSID match, with the ssid stored in the database. I tried to add the Check Attibute « Called-Station-id » == « SSID name » to the user profile but this is not working. I also tried to add the attribue Allow-called-station-id but this is not working. What is the right check attribute to add to the user profile please, for a check on the SSID name ? Thanks for your help 😉
