Enable user account - Ansible module user
How to enable a user without password lock and with the appropriate shell in Linux.


How to Enable a user account with Ansible?
I’m going to show you a live demo with some simple Ansible code. I’m Luca Berton and welcome to today’s episode of Ansible Pilot.
Ansible enable user account
Today we’re talking about the Ansible module user
.
The full name is ansible.builtin.user, which means that is part of the collection of modules “builtin” with ansible and shipped with it.
It’s a module pretty stable and out for years, it manages user accounts.
It supports a huge variety of Linux distributions, SunOS and macOS, and FreeBSD.
For Windows, use the ansible.windows.win_user
module instead.
Parameters
- name string - username
- state string - present/absent
- password_lock boolean - no/yes
- shell string - “/bin/bash”
This module has many parameters to perform any task.
The only required is “name”, which is the username.
The parameter “state” allows us to create or delete a user.
The “password_lock” parameter specifies to unlock the user password if locked.
This parameter uses the passwd
tool to change a password by changing it to a value that matches no possible encrypted value (it adds a ´!´ at the beginning of the password). To enable our user obviously we need to disable this parameter.
The “shell” parameter specifies the user shell. Two very special are the nologin
and false
shell. Apply the value of “/bin/bash” is going to restore user access.
