Freeradius + Called-Station-ID?

Question

linux

Good afternoon!

My name is Denis, I am setting up hotspot authentication using Captive Portal + Freeradius + Mysql.
In general, everything works flawlessly, but there was an idea how to make the access point recognize the previously logged in user not by login and password, but by Mac address, I found an interesting method here:
https://wiki.yola.ru/freeradius /freeradius_wifi
user Cleartext-Password := "pass", Calling-Station-Id == "1a-2b-3c-4d-5e-6f"
user Cleartext-Password := "pass", Calling-Station-Id == " aa-bb-cc-dd-ee-ff"
user Cleartext-Password := "pass", Calling-Station-Id == "11-22-33-44-55-66
" Called-Station-ID is assigned a login and password, but everything is in a text file,

I ask experts to respond and help to understand ...
