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.
Notes
-----
* 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.
* Using `externalmember` or `idoverrideuser` is only supported with `ipaapi_context: server`. With 'client' context, module execution will fail.
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: 2.14+
**Node**
* Supported FreeIPA version (see above)
Usage
=====
Example inventory file
```ini
[ipaserver]
ipaserver.test.local
```
Example playbook to add groups:
```yaml
---
- 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:
```yaml
---
- 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`:
```json
{
"groups": [
{
"name": "group1",
"description": "description group1"
},
{
"name": "group2",
"description": "description group2"
}
]
}
```
And ensure the presence of the groups with this example playbook:
```yaml
---
- 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:
```yaml
---
- 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:
```yaml
---
- 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:
```yaml
---
- 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:
```yaml
---
- 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:
```yaml
---
- 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:
```yaml
---
- 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:
```yaml
---
- 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:
```yaml
---
- 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
```
