Getting started

Support for libuser library

The role uses the libuser library, supported by the group and user Ansible modules, to manage the UNIX groups and accounts present on the hosts. The library is used to ensure that the groups and accounts created locally on the host that uses the LDAP directory as the user/group database have UID/GID values in the correct ranges, thus avoiding collisions with the LDAP directory UID/GID ranges. Without the libuser these local groups and accounts would be created in the LDAP UID/GID ranges, since the normal UNIX user management tools pick the next UID/GID based on the contents of the getent output, and not from the local user and group databases.

This behaviour can be controlled using the item.local parameter, which by default is enabled and shouldn't be specified directly unless you want to override the use of the libuser library for some reason. Due to issues with the Ansible modules, additional UNIX groups are managed using normal UNIX tools instead of their libuser equivalents.

Example inventory

The debops.users Ansible role is included by default in the common.yml DebOps playbook; you don't need to do anything to have it executed.

If you don’t want to let debops.users manage user accounts, you can disable it with the following setting in your inventory:

users__enabled: False

Example playbook

If you are using this role without DebOps, here's an example Ansible playbook that uses the debops.users role:


- name: Manage local users and groups
  collections: [ 'debops.debops', 'debops.roles01',
                 'debops.roles02', 'debops.roles03' ]
  hosts: [ 'debops_all_hosts', 'debops_service_users' ]
  become: True

  environment: '{{ inventory__environment | d({})
                   | combine(inventory__group_environment | d({}))
                   | combine(inventory__host_environment  | d({})) }}'


    - role: libuser
      tags: [ 'role::libuser', 'skip::libuser' ]

    - role: users
      tags: [ 'role::users', 'skip::users' ]

Ansible tags

You can use Ansible --tags or --skip-tags parameters to limit what tasks are performed during Ansible run. This can be used after host is first configured to speed up playbook execution, when you are sure that most of the configuration has not been changed.

Common role tags:


Main role tag, should be used in the playbook to execute all of the role tasks as well as role dependencies.


Main role tag, should be used in the playbook to skip all of the role tasks.


Used in specific tasks that might break in the Ansible --check mode on first run of the role on a host, but not subsequent runs. It can be used to skip these tasks in such case.

You can see full list of available role tags by executing the command:

debops run service/users --list-tags
