Valid SSL certificate deployment process

Hello All, I am using FR 3.0.8 version. I have done setup EAP-TTLS with PAP. For local setup and testing, I have used self-signed certificates. Now my setup and configuration is done and I want to do setup on production side. I have following certificates from CA, however, I am not getting how do I deploy certificates in FreeRadius because /etc/raddb/certs folder contains lots of certificate and its related to file. Root-ca.cer Ca.cer Server.cer Kindly help me on this? --- Thanks, Sunil Kulkarni
