openswan only allows one tunnel at a time to use the same x509 certificate in RHEL5

Issue

• When using x509 certificates for authentication, openswan version 2.6.21 does not allow more than one tunnel at the same time to use the same x509 certificate

• When a second tunnel using the same x509 certificate is brought up, the existing tunnel is removed

• In openswan version 2.6.14 multiple connections between peers using the same x509 certificates work

• Should openswan support using the same x509 client certificate for more than one tunnel at the same time?
