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?

   You can add them there if you want, dovecot combines all the files into one

how to enable PowerDNS/Weakforced with Fedora and sendmail

I took suggestions from https://forge.puppet.com/fraenki/wforce to set
these in /etc/dovecot/conf.d/95-auth.conf

auth_policy_server_url = http://localhost:8084/
auth_policy_hash_nonce = our_password
auth_policy_server_api_header = "Authorization: Basic
hash_from_running_echo-n_base64"
auth_policy_server_timeout_msecs = 2000
auth_policy_hash_mech = sha256
auth_policy_request_attributes = login=%{requested_username}
pwhash=%{hashed_password} remote=%{rip} device_id=%{client_id} protocol=%s
auth_policy_reject_on_fail = no
auth_policy_hash_truncate = 8
auth_policy_check_before_auth = yes
auth_policy_check_after_auth = yes
auth_policy_report_after_auth = yes

And auth_debug=yes

in /usr/local/etc/wforce.conf
webserver("0.0.0.0:8084", "our_password")
So when I run:
curl -X POST -H "Content-Type: application/json" --data
'{"login":"ouruser", "remote":
"127.0.0.1", "pwhash":"our_password"}'
http://127.0.0.1:8084/?command=allow -u wforce:our_passwordi
{"msg": "", "r_attrs": {"defaultReturn":
"1"}, "status": 0}

What's the value of wforce and super represent? -u for user? and super is
the password for the user?

curl -X GET http://127.0.0.1:8084/?command=ping -u wforce:super

I always get:
{"status":"failure",
"reason":"Unauthorized"}

Using Squirrelmail and logging in brings up the mails but I see these
Policy server HTTP error: 401 Unauthorized errors over and over:
