do you use a official certificate or an internal ?
We us a internal for testing and you have to add the root certification authority to your trusted certification authorities. If the certificate is from a windows CA you have to convert it with OpenSSL-tools to get a valid pem.
Oh, I just installed the "ratpack" plugin and it worked, and those fixes were rolled into the latest version.
Does this plugin help with ADFS problems?
If yes, where can I get it ?
With "latest version" do you mean 6.0.2? We are in test envirnment on 6.0.0.
