        will always attempt to load the type or feature (which can be an
        expensive operation) unless it has already been loaded successfully.
        This makes it possible for a single agent run to, e.g., install a
        package that provides the underlying capabilities for a type or feature,
        and then later load that type or feature during the same run (even if
        the type or feature had been tested earlier and had not been available).

        If this setting is set to false, then types and features will only be
        checked once, and if they are not available, the negative result is
        cached and returned for all subsequent attempts to load the type or
        feature.  This behavior is almost always appropriate for the server,

        features that are checked frequently.

        Which node data plugin to use when compiling node catalogs.

        When Puppet compiles a catalog, it combines two primary sources of info: the main manifest,
        and a node data plugin (often called a "node terminus," for historical reasons). Node data
        plugins provide three things for a given node name:

        1. A list of classes to add to that node's catalog (and, optionally, values for their
           parameters).
        2. Which Puppet environment the node should use.
        3. A list of additional top-scope variables to set.

        The three main node data plugins are:

        * `plain` --- Returns no data, so that the main manifest controls all node configuration.
        * `exec` --- Uses an
          [external node classifier (ENC)](https://docs.puppet.com/puppet/latest/nodes_external.html),
          configured by the `external_nodes` setting. This lets you pull a list of Puppet classes
          from any external system, using a small glue script to perform the request and format the
          result as YAML.
        * `classifier` (formerly `console`) --- Specific to Puppet Enterprise. Uses the PE console
          for node data."

      A value of `0` will disable caching. This setting can also be set to
      `unlimited`, which will cache environments until the master is restarted
      or told to refresh the cache.

      You should change this setting once your Puppet deployment is doing
      non-trivial work. We chose the default value of `0` because it lets new
      users update their code without any extra steps, but it lowers the
      performance of your Puppet master.

      We recommend setting this to `unlimited` and explicitly refreshing your
      Puppet master as part of your code deployment process.

      * With Puppet Server, you should refresh environments by calling the
        `environment-cache` API endpoint. See the docs for the Puppet Server
        administrative API.
      * With a Rack Puppet master, you should restart the web server or the
        application server. Passenger lets you touch a `restart.txt` file to
        refresh an application without restarting Apache; see the Passenger docs
        for details.

      We don't recommend using any value other than `0` or `unlimited`, since
      most Puppet masters use a pool of Ruby interpreters which all have their
      own cache timers. When these timers drift out of sync, agents can be served

A comma-separated list of alternate DNS names for Puppet Server. These are extra
hostnames (in addition to its `certname`) that the server is allowed to use when
serving agents. Puppet checks this setting when automatically requesting a
certificate for Puppet agent or Puppet Server, and when manually generating a
certificate with `puppet cert generate`.

In order to handle agent requests at a given hostname (like
"puppet.example.com"), Puppet Server needs a certificate that proves it's
allowed to use that name; if a server shows a certificate that doesn't include
its hostname, Puppet agents will refuse to trust it. If you use a single
hostname for Puppet traffic but load-balance it to multiple Puppet Servers, each
of those servers needs to include the official hostname in its list of extra
names.

**Note:** The list of alternate names is locked in when the server's
certificate is signed. If you need to change the list later, you can't just
change this setting; you also need to:

* On the server: Stop Puppet Server.
* On the CA server: Revoke and clean the server's old certificate. (`puppet cert clean <NAME>`)
* On the server: Delete the old certificate (and any old certificate signing requests)
  from the [ssldir](https://docs.puppetlabs.com/puppet/latest/reference/dirs_ssldir.html).
* On the server: Run `puppet agent -t --ca_server <CA HOSTNAME>` to request a new certificate
* On the CA server: Sign the certificate request, explicitly allowing alternate names
  (`puppet cert sign --allow-dns-alt-names <NAME>`).
* On the server: Run `puppet agent -t --ca_server <CA HOSTNAME>` to retrieve the cert.
* On the server: Start Puppet Server again.

To see all the alternate names your servers are using, log into your CA server
and run `puppet cert list -a`, then check the output for `(alt names: ...)`.
Most agent nodes should NOT have alternate names; the only certs that should
have them are Puppet Server nodes that you want other agents to trust.

An optional file containing custom attributes to add to certificate signing
requests (CSRs). You should ensure that this file does not exist on your CA
puppet master; if it does, unwanted certificate extensions may leak into
certificates created with the `puppet cert generate` command.

If present, this file must be a YAML hash containing a `custom_attributes` key
and/or an `extension_requests` key. The value of each key must be a hash, where
each key is a valid OID and each value is an object that can be cast to a string.

Custom attributes can be used by the CA when deciding whether to sign the
certificate, but are then discarded. Attribute OIDs can be any OID value except
the standard CSR attributes (i.e. attributes described in RFC 2985 section 5.4).
This is useful for embedding a pre-shared key for autosigning policy executables
(see the `autosign` setting), often by using the `1.2.840.113549.1.9.7`
("challenge password") OID.

Extension requests will be permanently embedded in the final certificate.
Extension OIDs must be in the "ppRegCertExt" (`1.3.6.1.4.1.34380.1.1`) or
"ppPrivCertExt" (`1.3.6.1.4.1.34380.1.2`) OID arcs. The ppRegCertExt arc is
reserved for four of the most common pieces of data to embed: `pp_uuid` (`.1`),
`pp_instance_id` (`.2`), `pp_image_name` (`.3`), and `pp_preshared_key` (`.4`)
--- in the YAML file, these can be referred to by their short descriptive names
instead of their full OID. The ppPrivCertExt arc is unregulated, and can be used
for site-specific extensions.

a certificate signed by a root CA the behavior is equivalent to the 'leaf' setting, and if Puppet attempts to verify
a certificate signed by an intermediate CA then verification will fail as Puppet will be unable to load the multiple

        The file specified in this setting may be either a **configuration file**
        or a **custom policy executable.** Puppet will automatically determine
        what it is: If the Puppet user (see the `user` setting) can execute the
        file, it will be treated as a policy executable; otherwise, it will be
        treated as a config file.

        If a custom policy executable is configured, the CA puppet master will run it
        every time it receives a CSR. The executable will be passed the subject CN of the
        request _as a command line argument,_ and the contents of the CSR in PEM format
        _on stdin._ It should exit with a status of 0 if the cert should be autosigned
        and non-zero if the cert should not be autosigned.

        If a certificate request is not autosigned, it will persist for review. An admin
        user can use the `puppet cert sign` command to manually sign it, or can delete
        the request.

        like it does when running normally. However, if a resource attribute is not in
        the desired state (as declared in the catalog), Puppet will take no
        action, and will instead report the changes it _would_ have made. These
        simulated changes will appear in the report sent to the puppet master, or
