<p>I have a Site to Site VPN between Strongswan and Cisco working over
PSK. Wanted to upgrade it to authenticate via Certificates, but can't
get it done. Receiving following error: <br></p><p><br></p>

<p>The Certificates for both ends are signed by two different CA, but
already exchanged public root and intermediate certs. On cisco side I
see the tunnel goes up for both Phase 1 and 2, so its good. Strongswan
has problem with it and no SA is up.<br></p>
<p>Configuration:</p>
