Ansible user add for RHEL and Ubuntu

This is a quick ansible script to add a user to either RHEL or Ubuntu and even hide said user from the gui login if you want. A customer needed this to limit the users posted on the login page when logging via the GUI.

Cut and paste this into a file named user-someusername.yml
To run use "asible-playbooks -i hostIP, user-someusername.yml".

- hosts: all
  user: root
  vars:
    userName: <username>
    userFull: <Full Username>
    userPassword: <user your hash from the /etc/passwd file>
    userKey: <generate a key pair using "ssh-keygen -t rsa -b 4096" and cut-n-paste your pub key here. >
