AttributeError: 'LDAPConnector' object has no attribute '_con'

I'm trying to integrate pas.plugins.ldap with a Plone local environment, but it is throwing an exception when I open the control panel (http://plone.localhost:8080/Plone/plone_ldapcontrolpanel).

#docker-compose.yml

version: "3"
services:

  webserver:
    image: nginx
    volumes:
      - ./default.conf:/etc/nginx/conf.d/default.conf
    depends_on:
      - backend
      - frontend
    ports:
    - "80:80"

  frontend:
    image: plone/plone-frontend:16.0.0-alpha.42
    environment:
      RAZZLE_INTERNAL_API_PATH: http://backend:8080/Plone
    ports:
    - "3000:3000"
    depends_on:
      - backend

  backend:

    environment:
      SITE: Plone
      ADDONS: pas.plugins.ldap==1.8.1
    ports:
    - "8080:8080"

Try to pin node and node.ext.ldap to previous version, ie

ADDONS: pas.plugins.ldap==1.8.1 node==1.0 node.ext.ldap==1.0

[jensens]

Indeed. We need to follow up with changes in node.ext.ldap. Pull requests are welcome. At the moment I have no time to fix this myself.
