Dear Jouni and all!
Thank you for your quick answer.

First of all, you can find the certificates and certificate chains,
cleint and server key files (pwd is ikev2meas) I tried to use until this
Could you check them for me?
For information on the files: you should read the
"generate-certificates" and "generate certificate-chains" text files
I have also one or two explicit questions in generate-certificate.txt.

So as I understand, wpa_supplicant configuraion differs from the
configuration I used at freeradius, since there, I put the server
chain into "server certificate file", in trust order, and I put only the
rootCA.crt to the "Trusted CAs list" parameter.
Perhaps, wpa-supplicant-like configuration could also work for
freeradius, and if I now, how exactly wpasupplicant configuration works,
I will try the same thing with freeradius configuration.
Could you examplify how to configure up a client-side certificate chain,
for example with my sample certificates, if they seem to be good?
What about the ordering of CA certs in the ca_cert? As I understood this
will also be a concatenated PEM format file.

So, how can I reach that they find the commonly trusted CA for example if
- server side trusts the following chain: subsubCA1, subCA1, rootCA
- client side trusts the following chain: subsubCA2, subCA2, rootCA
(note: server trusts subsubCA1, client trusts subsubCA2, the common CA
