Question

linux

Hello, how to set up authorization on freeRadius 3 version through an external script, in this case PHP.
Can anyone come across? please share! =)
Now I'm trying, writes:

Thu Mar 15 13:40:33 2018 : ERROR: (1) php: ERROR: Failed parsing output from: /usr/bin/php -f /etc/freeradius/3.0/kAPIauth.php: Expecting operator
Thu Mar 15 13:40:34 2018 : ERROR: (1) php: ERROR: Program returned code (0) and output 'Accept'

Or tell me what my script should return? I don't understand at all
