The server certificate, that configured by option `certificate_file`
in `tls-config tls-common` section (eap module)

Yes, I know about it. But in my case I can not issue new server
certificate from the same CA. That CA was bought by other CA, and now
new certificates are signed with different root certificate. This
cause some problems. Clients that verify server certificate using CA
certificate that stored in radius configuration, now has broken trust

The idea of using two certificates aims to avoid similar problems in the future.

Ok, I got it.
Thank you very much for your answers.
