[ovirt-users] Replace Engine Self-Signed Certificate

Hi, I'm trying to replace the self-signed certificate in the engine. I updated the four files listed here http://www.ovirt.org/develop/release-management/features/infra/pki/ But on restarting Apache and logging in I get the following error, "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" What am I missing? Thanks, Alan
