  puppetdb:
    server_urls:
      - '<https://pdb.domain.edu:8081>'
    cacert: '~/.ssh/certs/puppet_ca.crt'
    cert: '~/.ssh/certs/admin.cert'
    key: '~/.ssh/certs/admin_key.pem'
  old-puppetdb:
    server_urls:
      - '<https://puppetdb01.domain.edu:8081>'
    cacert: '~/.ssh/certs/puppet3_ca.pem'
    cert: '~/.ssh/certs/admin_puppet3.pem'
    key: '~/.ssh/certs/admin_puppet3_key.pem'
