One possible way to obtain this certificate is to use ConsoleOne to export the public key. To do this, start ConsoleOne and navigate to the SSL CertificateDNS object. On the Properties dialog of the SSL CertificateDNS object, select Public Key Certificate from the Certificates tab. Press the Export button to begin the process of exporting the certificate. You do not need to export the private key. Store the file in DER format.
Copy the DER file to the Identity Manager application server. Then add the certificate to the jdk\jre\lib\security\cacerts keyfile using keytool or other certificate management tool. The keytool utility is shipped with the Java SDK. Refer to the Java documentation for more information about the keytool utility.
