eap_peer_config::ca_path2 field

ca_path2 - Directory path for CA certificate files (PEM) (Phase 2) This path may contain multiple CA certificates in OpenSSL format. Common use for this is to point to system trusted CA list which is often installed into directory like /etc/ssl/certs. If configured, these certificates are added to the list of trusted CAs. ca_cert may also be included in that case, but it is not required. This field is like ca_path, but used for phase 2 (inside EAP-TTLS/PEAP/FAST tunnel) authentication.
