Thank you

Gday,

Thanks to all and special thank to Alan (not all heroes wear capes).

In case anyone else is struggling with error 20 at 0 depth, what I did 
was to run ./bootstrap in etc/raddb/certs, ensured that the certificates 
had been copied across to etc/freeradius/certs and then rehashed them 
by using the following command at root level: c_rehash 
/etc/freeradius/certs/


Now I need to generate actual proper certificates and not just use 
example ones. Wish me luck!
