Usage

Add Stouts.openvpn to your roles and set vars in your playbook file.

Example:

- hosts: all

  roles:
  - Stouts.openvpn

  vars:
    openvpn_use_pam: yes
    openvpn_clients: [myvpn]
    openvpn_use_pam_users:
    - { name: user1, password: password1 }
    - { name: user2, password: password2 }

Install and copy client's configuration from /etc/openvpn/keys/myvpn.tar.gz file. If you set openvpn_unified_client_profiles: yes, then you only need to copy /etc/openvpn/keys/myvpn.ovpn, as all the config info will be inlined.
