Group module

Description

The group module allows to ensure presence and absence of groups and members of groups.

The group module is as compatible as possible to the Ansible upstream ipa_group module, but additionally offers to add users to a group and also to remove users from a group.

Note

Ensuring presence (adding) of several groups with mixed types (external, nonposix and posix) requires a fix in FreeIPA. The module implements a workaround to automatically use client context if the fix is not present in the target node FreeIPA and if more than one group is provided to the task using the groups parameter. If ipaapi_context is forced to be server, the module will fail in this case.

Features

• Group management

Supported FreeIPA Versions

FreeIPA versions 4.4.0 and up are supported by the ipagroup module.

Some variables are only supported on newer versions of FreeIPA. Check Variables section for details.

Requirements

Controller

• Ansible version: 2.15+

Node

• Supported FreeIPA version (see above)

Usage

Example inventory file

[ipaserver]
ipaserver.test.local

Example playbook to add groups:

---
- name: Playbook to handle groups
  hosts: ipaserver
  become: true

  tasks:
  # Create group ops with gid 1234
  - ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: ops
      gidnumber: 1234

  # Create group sysops
  - ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: sysops
      user:
      - pinky

  # Create group appops
  - ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: appops

These three ipagroup module calls can be combined into one with the groups variable:

---
- name: Playbook to handle groups
  hosts: ipaserver

  tasks:
  - name: Ensure groups ops, sysops and appops are present
    ipagroup:
      ipaadmin_password: SomeADMINpassword
      groups:
      - name: ops
        gidnumber: 1234
      - name: sysops
        user:
        - pinky
      - name: appops

You can also alternatively use a json file containing the groups, here groups_present.json:

{
  "groups": [
    {
      "name": "group1",
      "description": "description group1"
    },
    {
      "name": "group2",
      "description": "description group2"
    }
  ]
}

And ensure the presence of the groups with this example playbook:

---
- name: Tests
  hosts: ipaserver
  gather_facts: false

  tasks:
  - name: Include groups_present.json
    include_vars:
      file: groups_present.json

  - name: Groups present
    ipagroup:
      ipaadmin_password: SomeADMINpassword
      groups: "{{ groups }}"

Example playbook to rename a group:

---
- name: Playbook to rename a single group
  hosts: ipaserver
  become: false
  gather_facts: false

  tasks:
  - name: Rename group appops to webops
    ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: appops
      rename: webops
      state: renamed

Several groups can also be renamed with a single task, as in the example playbook:

---
- name: Playbook to rename multiple groups
  hosts: ipaserver
  become: false
  gather_facts: false

  tasks:
  - name: Rename group1 to newgroup1 and group2 to newgroup2
    ipagroup:
      ipaadmin_password: SomeADMINpassword
      groups:
      - name: group1
        rename: newgroup1
      - name: group2
        rename: newgroup2
      state: renamed

Example playbook to add users to a group:

---
- name: Playbook to handle groups
  hosts: ipaserver
  become: true

  tasks:
  # Add user member brain to group sysops
  - ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: sysops
      action: member
      user:
      - brain

action controls if a the group or member will be handled. To add or remove members, set action to member.

Example playbook to add group members to a group:

---
- name: Playbook to handle groups
  hosts: ipaserver
  become: true

  tasks:
  # Add group members sysops and appops to group ops
  - ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: ops
      group:
      - sysops
      - appops

Example playbook to add members from a trusted realm to an external group:

---
- name: Playbook to handle groups.
  hosts: ipaserver
  
  tasks:
  - name: Create an external group and add members from a trust to it.
    ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: extgroup
      external: yes
      externalmember:
      - WINIPA\\Web Users
      - WINIPA\\Developers

Example playbook to add nonposix and external groups:

---
- name: Playbook to add nonposix and external groups
  hosts: ipaserver

  tasks:
  - name: Add nonposix group sysops and external group appops
    ipagroup:
      ipaadmin_password: SomeADMINpassword
      groups:
      - name: sysops
        nonposix: true
      - name: appops
        external: true

Example playbook to remove groups:

---
- name: Playbook to handle groups
  hosts: ipaserver
  become: true

  tasks:
  # Remove groups sysops, appops and ops
  - ipagroup:
      ipaadmin_password: SomeADMINpassword
      name: sysops,appops,ops
      state: absent

Example playbook to ensure groups are absent:

---
- name: Playbook to handle groups
  hosts: ipaserver

  tasks:
  - name: Ensure groups ops and sysops are absent
    ipagroup:
      ipaadmin_password: SomeADMINpassword
      groups:
      - name: ops
      - name: sysops
      state: absent
