FreeRadius ignoring authentication requests

[Marcelito de Guzman]

Good Day,

Our FreeRadius server seems to be ignoring authentication requests. I
confirmed that the requests are being received via `radsniff -i en18`:
Access-Request Id 187 40.231.3.9:54182 -> 10.129.1.5:1812 +2222.346
User-Name = "bob"
User-Password = "ٞP\322\n\159\34175\760\376%\250\366x\402"
NAS-Identifier = "cor1"
Calling-Station-Id = "10.129.1.20"
NAS-IP-Address = 40.231.3.9

However, `radiusd -X` doesn't show that it's processing it. What is
the plausible cause for this?

radiusd -X:
