Part 5 of my homelab downsizing series: a week building the wrong cert automation (acme-proxy — turns out it doesn't support Cloudflare DNS-01), then six days and three attempts standing up FreeIPA as a subordinate CA before shelving it for Samba AD. Two burned signing ceremonies, one silently-discarded private key. #homelab #pki #freeipa #selfhosted
