Domain Mapping, SSL and WP Engine

Hello, i would like to know how i should configure the settings for the WPMUDEV Domain Mapping plugin in order to have an SSL Certificate for the mapped domain on WP Engine.

According to WP Engine the only domain mapping plugin they recommend is the “automattic” one …

But i would like to use your plugin because of its integration with Pro Sites…

I have a SSL setup for my main site, working fina, without issues, another one for a subdomain (no domain mapped to it) …

But when i try to set a ssl for a domain name that is mapped to a subsite, i get redirect loops…

Do i have to have a ssl certificate for the subdomain to which i will map the domain name to?

example:

turn http://subdomain.maindomain.com to https://subdomain.maindomain.com befor mapping it to https://mappeddomain.com

What settings do you recommend for the plugin under wp-admin network settings domainmapping ?

Thanks in advance…

Sorry for the long explanation
