Ansible Role Users
====================

Ansible role l3d.users.user to create Users with their group and their SSH Public Keys to their account.
Optionally you can also create an ansible user and add specified ssh keys to his home and all keys of admin users.

There are two variables to define users. The ``l3d_users__default_users`` is ment to put to your group_vars to define a default for your system. The ``l3d_users__local_users`` could be put in your host_vars to define host-specific user and admin roles.

 Variables:
