Run the following command (all on one line):
keytool -list -v -keystore /opt/WiKID/private/intCAKeys.p12 -storetype pkcs12 -storepass yourpassphrase
keytool -list -v -keystore /opt/WiKID/private/localhost.p12 -storetype pkcs12 -storepass yourpassphrase
for the localhost certificate.
If you created the certificates and then discovered that the clock was not correct, your certificates might be expired. You can simply re-create them via the WiKIDAdmin.
