Create SSL Wildcard Certificate to AD Manager Plus

Create SSL Wildcard Certificate to AD Manager Plus

Hi everyone, 
I need to create a SSL Wildcard certificate to AD Manager Plus.

I ve seen this kb but it does't specify if its a wildcard cert.

Also, I ve seen a guide to install this wildcard certs, but idk how to create it. Or how to create a csr to a wildcart cert.

Can someone help me please?

Thank you all
