Case sensitivity of provisioner name?

[strarsis]

Certbot uses acme as provisioner name. However, when step-ca is configured to use ACME as provisioner name, it will not match requests from Certbot for acme as it compares the name case-sensitively, hence it will find now provisioner and fail to handle the certbot request.

Is case-sensitivity of the provisioner name something that is defined in the ACME RFC (can't find the word "provisioner" there though)? Or an assumed *nix-like behaviour?

@strarsis the provisioner name, from the perspective of an ACME client, is just part of the ACME server URL. And since URLs are case sensitive, it makes sense that a provisioner name would also be case sensitive.step-ca uses /acme/<provisioner_name> for its ACME endpoints. With certbot you can provide the server URL with --server, eg.--server https://ca.internal/acme/ACME/directory

Hope this helps.
