Puppet also provides a policy-based interface for autosigning, which can be more flexible and secure. The
autosign.conf file is the simpler and less secure method.

autosign.conf file is a list of certnames or domain name globs (one per line). Each line represents a node name or group of node names whose certificate requests should be automatically signed when the CA Puppet master receives them.

Note that domain name globs do not function as normal globs: an asterisk can only represent one or more subdomains at the front of a certname that resembles a fully-qualified domain name. (That is, if your certnames don’t look like FQDNs, you can’t use
autosign.conf to full effect.
Note: Since any host can request any certname, autosigning with
autosign.conf is essentially insecure. See the reference page about certificate autosigning for more context.
