Hi all, just beginning my adventure with Ansible. Following situation: I'm trying to ensure that a user called "ansible" is present on all hosts that should be managed by Ansible. Creating group and user works so far. Now I'm trying to enable password-less SSH login for that user by copying a well known key pair to the host. ### playbook.yml ---

that is what the authorized\_keys module is for [http://docs.ansible.com/ansible/authorized\_key\_module.html](http://docs.ansible.com/ansible/authorized_key_module.html), use that instead to copy the public key. Also you should not be copying the private key. ---
