I am attempting to generate a keystore for a client to enable them to
bypas the security warning received in the browser. My problem is, they
obtained the certificates without generating a certificate request
using keytool, so no matter how I import their certificates into my
keystore, the browser does not recognize the CA cert inside the
keystore, and warns the user that the certificate is not signed by a CA
they've chosen to trust. Any ideas?

Thanks,
Chris
