Can Let's Encrypt be used for Windows Server 2012 r2 Essentials Anywhere Access Certificates?

Specifically, is there a way to setup an auto renewal certificate for Windows Server 2012 R2 Essentials Anywhere Access?

This would be awesome any news on this?

check out the powershell clients

Here you go Get a free Let’s Encrypt SSL certificate for Access Anywhere and automatically renew it.

It seems that 1.9.3 fails certificate renewal. Version 1.9.1 works just fine, see Get a free Let’s Encrypt SSL certificate for Access Anywhere and automatically renew it.

I have updated the tutorial again, we now use Certify the web as our client.
