How to configure SoapUI with server certificate authenticati

Hi,

I am just starting using SoapUI and I need to configure it with server certificate authentication.
I can't find a way to do this. Everything I have found on the internet about server certificate seems to point towards Mock services but I don't really understand what they are so I can't be sure about what to do.

Could you please help me ?

I am using SoapUI 3.6.1.

Thanks a lot,
