When importing a Resigning Certificate Authority into the SSLV sometimes a generic 'O' error will be presented in the UI.
This error will be seen when the certificate being imported does not contain an Organization Name as part of the DN details.
See attached image.
This error is only cosmetic and can be acknowledged by pressing OK then Cancel. The certificate will still be loaded into the SSLV even though the error is presented to the user.
Make sure to apply the changes.
