[PVE-User] Step-CA And Proxmox

[duluxoz]

Hi All,

We run an internal PKI using the Step-CA project 
(https://smallstep.com/certificates/).

Step-CA can respond to ACME Client requests in exactly the same way that 
Let's Encrypt does - you simply point the client ACME App/Script 
(Certbot, acme.sh, etc) to the local CA instead of Let's Encrypt's servers.

So our question is: Within Proxmox, which can handle Let's Encrypt 
Certs, how do we (is it possible too) point the Proxmox ACME Client to 
our internal Step-CA servers? Is there a config setting we've missed, an 
Add-On, etc, or something else?

Thanks in advance
