AD CS - Public key does not meet the minimum size required (CERTSRV_E_KEY_LENGTH)

[arp-mbender]

I'm trying to set up acme2certifier for my needs, and I feel like I'm "this" close. I've got acme2certifier in a docker and talking with my AD CS with a user/password. Unfortunately, I wasn't sure what kind of template was required for this, so I created duplicated one for Web Server.

And it seems like acme2certifier does attempt to:

• use the correct user / pass and get valid responses from the AD CS
• use the correct template (i.e. what I created)

Where I fail is in my CA template itself, clearly. Any idea what kind of settings are needed for an ACME template on AD CS?

On reflection this shouldn't be an issue - I've made a discussion instead.
