Hello everyone, I have a problem to authentication with REST module. I enable the rest module and added the rest to sites-enabled/default file 1- enabled the rest module ln -s ../mods-available/rest /etc/freeradius/mods-enabled/rest 2- changed the url of rest connect_uri = "http://10.0.0.20/" 3- add the rest into nano /etc/freeradius/sites-enabled/default authorize { rest } authenticate { rest } accounting { rest } post-auth { rest } My basic configuration is like that, when I send the get request by Postman tool, I am getting 404 Bad Request. GET http://10.0.0.20/user/%{User-Name}/mac/%{Called-Station-ID}?action=authenticate I read the documents below, but I didn't get it https://networkradius.com/doc/3.0.10/raddb/mods-available/rest.html https://github.com/FreeRADIUS/freeradius-server/blob/v3.0.x/raddb/mods-avail... I didn't underestand exatly how to use rest module of freeradius 3.0.15 on Ubuntu 16.04. I just need to authenticate users and record the users to database via rest API. Apache and PHP already installed on the server. Are there any other requirement ? Thanks in advance, Görkem İnanç KORKMAZ Junior System Engineer
