Chapter 9. Using Ansible to automate group membership in IdM

Using automatic group membership, you can assign users and hosts user groups and host groups automatically, based on their attributes. For example, you can:

Divide employees' user entries into groups based on the employees' manager, location, position or any other attribute. You can list all attributes by entering ipa user-add --help on the command-line.
Divide hosts into groups based on their class, location, or any other attribute. You can list all attributes by entering ipa host-add --help on the command-line.
Add all users or all hosts to a single global group.

You can use Red Hat Ansible Engine to automate the management of automatic group membership in Identity Management (IdM).

9.1. Using Ansible to ensure that an automember rule for an IdM user group is present
Copiar o link

The following procedure describes how to use an Ansible playbook to ensure an automember rule for an Identity Management (IdM) group exists. In the example, the presence of an automember rule is ensured for the testing_group user group.

Prerequisites

You know the IdM admin password.
The testing_group user group exists in IdM.
You have configured your Ansible control node to meet the following requirements:
- You are using Ansible version 2.13 or later.
- You have installed the ansible-freeipa package.
- The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
- The example assumes that the secret.yml Ansible vault stores your ipaadmin_password.
The target node, that is the node on which the ansible-freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.

Procedure

Navigate to your ~/MyPlaybooks/ directory:
```
cd ~/MyPlaybooks/
```
```
$ cd ~/MyPlaybooks/
```

Copy the automember-group-present.yml Ansible playbook file located in the /usr/share/doc/ansible-freeipa/playbooks/automember/ directory:

cp /usr/share/doc/ansible-freeipa/playbooks/automember/automember-group-present.yml automember-group-present-copy.yml

$ cp /usr/share/doc/ansible-freeipa/playbooks/automember/automember-group-present.yml automember-group-present-copy.yml

Copy to Clipboard

Toggle word wrap

Open the automember-group-present-copy.yml file for editing.

Adapt the file by setting the following variables in the ipaautomember task section:

Set the ipaadmin_password variable to the password of the IdM admin.
Set the name variable to testing_group.
Set the automember_type variable to group.
Ensure that the state variable is set to present.

This is the modified Ansible playbook file for the current example:

---
- name: Automember group present example
  hosts: ipaserver
  vars_files:
  - /home/user_name/MyPlaybooks/secret.yml
  tasks:
  - name: Ensure group automember rule admins is present
    ipaautomember:
      ipaadmin_password: "{{ ipaadmin_password }}"
      name: testing_group
      automember_type: group
      state: present

---
- name: Automember group present example
  hosts: ipaserver
  vars_files:
  - /home/user_name/MyPlaybooks/secret.yml
  tasks:

    ipaautomember:
      ipaadmin_password: "{{ ipaadmin_password }}"
      name: testing_group
      automember_type: group
      state: present

9.2. Using Ansible to ensure that a specified condition is present in an IdM user group automember rule
Copiar o link

Additional resources

The following procedure describes how to use an Ansible playbook to ensure that a specified condition exists in an automember rule for an Identity Management (IdM) group. In the example, the presence of a UID-related condition in the automember rule is ensured for the testing_group group. By specifying the .* condition, you ensure that all future IdM users automatically become members of the testing_group.

Prerequisites

You know the IdM admin password.
The testing_group user group and automember user group rule exist in IdM.
You have configured your Ansible control node to meet the following requirements:
- You are using Ansible version 2.13 or later.
- You have installed the ansible-freeipa package.
- The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
- The example assumes that the secret.yml Ansible vault stores your ipaadmin_password.
The target node, that is the node on which the ansible-freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.

Adapt the file by modifying the following parameters:

Rename the playbook to correspond to your use case, for example: Automember user group rule member present.
Rename the task to correspond to your use case, for example: Ensure an automember condition for a user group is present.
Set the following variables in the ipaautomember task section:
- Set the ipaadmin_password variable to the password of the IdM admin.
- Set the name variable to testing_group.
- Set the automember_type variable to group.
- Ensure that the state variable is set to present.
- Ensure that the action variable is set to member.
- Set the inclusive key variable to UID.
- Set the inclusive expression variable to .*

9.3. Using Ansible to ensure that a condition is absent from an IdM user group automember rule
Copiar o link

Additional resources

The following procedure describes how to use an Ansible playbook to ensure a condition is absent from an automember rule for an Identity Management (IdM) group. In the example, the absence of a condition in the automember rule is ensured that specifies that users whose initials are dp should be included. The automember rule is applied to the testing_group group. By applying the condition, you ensure that no future IdM user whose initials are dp becomes a member of the testing_group.

Prerequisites

You know the IdM admin password.
The testing_group user group and automember user group rule exist in IdM.
You have configured your Ansible control node to meet the following requirements:
- You are using Ansible version 2.13 or later.
- You have installed the ansible-freeipa package.
- The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
- The example assumes that the secret.yml Ansible vault stores your ipaadmin_password.
The target node, that is the node on which the ansible-freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.

Additional resources

The following procedure describes how to use an Ansible playbook to ensure an automember rule is absent for an Identity Management (IdM) group. In the example, the absence of an automember rule is ensured for the testing_group group.

Deleting an automember rule also deletes all conditions associated with the rule. To remove only specific conditions from a rule, see Using Ansible to ensure that a condition is absent in an IdM user group automember rule.

Follow this procedure to use Ansible to ensure that a condition is present in an IdM host group automember rule. The example describes how to ensure that hosts with the FQDN of .*.idm.example.com are members of the primary_dns_domain_hosts host group and hosts whose FQDN is .*.example.org are not members of the primary_dns_domain_hosts host group.

You have configured your Ansible control node to meet the following requirements:
- You are using Ansible version 2.13 or later.
- You have installed the ansible-freeipa package.
- The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
- The example assumes that the secret.yml Ansible vault stores your ipaadmin_password.
The target node, that is the node on which the ansible-freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.
