Usually in you config shoulb something like this:
[..]
leftcert=foo.pem
leftrsasigkey=%cert
rightcert=bar.pem
rightid=@remoteid (optional)
rightrsasigkey=%cert
authby=rsasig
[..]

The certificate will be checked in Phase1, you need to put your CA key,
your CA and the client certs in the right dirs under /etc/ipsec.d/....

For RSA only you put those Keys usually in a DNS, Openswan checks then the
key via fqdn.
