Depends on the settings (send_certreq, send_cert in swanctl.conf,
left|rightsendcert in ipsec.conf). With the default settings the client
will send certificate requests for all trusted CA certificates it has
loaded (root or intermediate), or if a CA is assigned in the config only
for that CA. As responder, if any certificate requests are received (no
matter for what CA) the end entity certificate along with the
intermediate CA certificates will be sent to the client.
