I'm trying to configure the Citrix Web Interface v5.2.0 and Java Client 9.7. I keep receiving the error:

SSL/TLS Error

You have not chosen to trust <Cert Authority> the issuer of the server security certificate.
The certificate authority is a trusted root authority on the computer used for testing and I know that the certificate has been imported correctly because the Windows ICA client works fine.

I have tried JRE 1.4.2u19, 1.6u3 and 1.6u13 and tried launching via IE 8 and Firefox 3.5.5.

The JRE has the option selected to use the Windows keystore and you can see the CA listed as a Secure Site certificate in the Java Control Panel app.

Please help!
