After upgrading from v 2.x, freeradius stopped working for me. I have done multiple tshooting steps which led me to believe that the application is not sending any data through MySQL, even though it states to do so.
So what I've discovered is that freeradius should send query to DB each time a user tries to authenticate. Several queries in fact.
To verify if there is any traffic going to the MySQL server I did tcpdmp:
tcpdump -i eth0 -n | grep 192.168.32.13 | grep -v ARP
After restarting the service and attempting to authenticate using radius there was nothing logged by tcpdump. It works if I do it manually (so neither the connection nor credentials are a problem).
Freeradius keeps saying that the user is not found in any groups:
(0) sql: Executing select query: SELECT groupname FROM radusergroup WHERE username = 'naven' ORDER BY priority
(0) sql: User not found in any groups
But the query directly in the DB is yielding a result:
MariaDB [radius]> SELECT groupname FROM radusergroup WHERE username = 'naven' ORDER BY priority;
+-----------+
| groupname |
+-----------+
| admin |
+-----------+
1 row in set (0.00 sec)
Also the below INSERT query is never saved to a database.
(0) sql: EXPAND INSERT INTO radpostauth (username, pass, reply, authdate) VALUES ( '%{SQL-User-Name}', '%{%{User-Password}:-%{Chap-Password}}', '%{reply:Packet-Type}', '%S')
(0) sql: --> INSERT INTO radpostauth (username, pass, reply, authdate) VALUES ( 'naven', 'XXXXXXXXXXXXXX', 'Access-Reject', '2019-10-19 16:44:03')
(0) sql: Executing query: INSERT INTO radpostauth (username, pass, reply, authdate) VALUES ( 'naven', 'XXXXXXXXXXXXXX', 'Access-Reject', '2019-10-19 16:44:03')
mysql -u radius -pEpyGju6EogSFua4u -h 192.168.32.13

I have added the radpostauth entry manually. I copied the query from some previous log to make sure it works. Also using above method to connect to MySQL confirmed my tcpdump working correctly- I could see legitimate MySQL traffic between the servers.
Throughout the post I only redacted some hostnames and 'pass' from radpostauth.
Server fault is limiting my message to 30k lines so I can't post whole freeradius -X log.

Can you please help me get this to work?
P.S. Can you advise on how should I send the rest of the logs? The logs is quite extensive and comments are capped at few hundred characters.
