how to enable PowerDNS/Weakforced with Fedora and sendmail

We have dovecot-1:2.3.3-1.fc29.x86_64 running on Fedora 29. I'd like to test wforce, from https://github.com/PowerDNS/weakforced.

I see instructions at the Authentication policy support page, https://wiki2.dovecot.org/Authentication/Policy

I see the Required Minimum Configuration: auth_policy_server_url = http://example.com:4001/ auth_policy_hash_nonce = localized_random_string

But when I search for these directives, they're not found: grep auth_policy_server_url /etc/dovecot/conf.d/*

Are these to be added to the /etc/dovecot/conf.d/10-auth.conf file? Does anyone know if a good tutorial?
