Chapter 10. Configuring global IdM settings using Ansible playbooks

Procedure

1. Open the /usr/share/doc/ansible-freeipa/playbooks/config/retrieve-config.yml Ansible playbook file for editing:

   ---
   - name: Playbook to handle global IdM configuration
     hosts: ipaserver
     become: no
     gather_facts: no
   
     vars_files:
     - /home/user_name/MyPlaybooks/secret.yml
     tasks:
     - name: Query IPA global configuration
       ipaconfig:
         ipaadmin_password: "{{ ipaadmin_password }}"
       register: serverconfig
   
     - debug:
         msg: "{{ serverconfig }}"

2. Adapt the file by changing the following:

   • The password of IdM administrator.
   • Other values, if necessary.
3. Save the file.

4. Run the Ansible playbook. Specify the playbook file, the file storing the password protecting the secret.yml file, and the inventory file:

   $ ansible-playbook --vault-password-file=password_file -v -i path_to_inventory_directory/inventory.file /usr/share/doc/ansible-freeipa/playbooks/config/retrieve-config.yml
   [...]
   TASK [debug]

           },
           "changed": false,
           "config": {

   }

Procedure

1. Optional: Identify the current IdM CA renewal server:

   $ ipa config-show | grep 'CA renewal'
     IPA CA renewal master: server.idm.example.com

2. Create an inventory file, for example inventory.file, and define ipaserver in it:

   [ipaserver]
   server.idm.example.com

3. Open the /usr/share/doc/ansible-freeipa/playbooks/config/set-ca-renewal-master-server.yml Ansible playbook file for editing:

   ---
   - name: Playbook to handle global DNS configuration
     hosts: ipaserver
     become: no
     gather_facts: no
     vars_files:
     - /home/user_name/MyPlaybooks/secret.yml
   
     tasks:
     - name: set ca_renewal_master_server
       ipaconfig:
         ipaadmin_password: "{{ ipaadmin_password }}"
         ca_renewal_master_server: carenewal.idm.example.com

4. Adapt the file by changing:

   • The password of IdM administrator set by the ipaadmin_password variable.
   • The name of the CA renewal server set by the ca_renewal_master_server variable.
5. Save the file.

6. Run the Ansible playbook. Specify the playbook file, the file storing the password protecting the secret.yml file, and the inventory file:

   $ ansible-playbook --vault-password-file=password_file -v -i path_to_inventory_directory/inventory.file /usr/share/doc/ansible-freeipa/playbooks/config/set-ca-renewal-master-server.yml

1. Log into ipaserver as IdM administrator:

   $ ssh admin@server.idm.example.com
   Password:
   [admin@server /]$

2. Request the identity of the IdM CA renewal server:

   $ ipa config-show | grep ‘CA renewal’
   IPA CA renewal master:  carenewal.idm.example.com

   The output shows the carenewal.idm.example.com server is the new CA renewal server.

Procedure

1. Optional: Use the retrieve-config.yml Ansible playbook to identify the current shell for IdM users. See Retrieving IdM configuration using an Ansible playbook for details.

2. Create an inventory file, for example inventory.file, and define ipaserver in it:

   [ipaserver]
   server.idm.example.com

3. Open the /usr/share/doc/ansible-freeipa/playbooks/config/ensure-config-options-are-set.yml Ansible playbook file for editing:

   ---
   - name: Playbook to ensure some config options are set
     hosts: ipaserver
     vars_files:
     - /home/user_name/MyPlaybooks/secret.yml
   
     tasks:
     # Set defaultlogin and maxusername
     - ipaconfig:
         ipaadmin_password: "{{ ipaadmin_password }}"
         defaultshell: /bin/bash
         maxusername: 64

4. Adapt the file by changing the following:

   • The password of IdM administrator set by the ipaadmin_password variable.
   • The default shell of the IdM users set by the defaultshell variable into /bin/sh.
5. Save the file.

6. Run the Ansible playbook. Specify the playbook file, the file storing the password protecting the secret.yml file, and the inventory file:

   $ ansible-playbook --vault-password-file=password_file -v -i path_to_inventory_directory/inventory.file /usr/share/doc/ansible-freeipa/playbooks/config/ensure-config-options-are-set.yml

1. Log into ipaserver as IdM administrator:

   $ ssh admin@server.idm.example.com
   Password:
   [admin@server /]$

2. Display the current shell:

   [admin@server /]$ echo "$SHELL"
   /bin/sh

   The logged-in user is using the sh shell.

Procedure

1. Navigate to your ~/MyPlaybooks/ directory:

   $ cd ~/MyPlaybooks/

2. Create a netbios-domain-name-present.yml Ansible playbook file.

3. Add the following content to the file:

   ---
   - name: Playbook to change IdM domain netbios name
     hosts: ipaserver
     become: no
     gather_facts: no
   
   
     vars_files:
     - /home/user_name/MyPlaybooks/secret.yml
   
     tasks:
       - name: Set IdM domain netbios name
         ipaconfig:
           ipaadmin_password: "{{ ipaadmin_password }}"
           netbios_name: IPADOM

4. Save the file.

5. Run the Ansible playbook. Specify the playbook file, the file storing the password protecting the secret.yml file, and the inventory file:

   $ ansible-playbook --vault-password-file=password_file -v -i inventory netbios-domain-name-present.yml

   When prompted, provide the vault file password.

Procedure

1. Navigate to your ~/MyPlaybooks/ directory:

   $ cd ~/MyPlaybooks/

2. Create a sids-for-users-and-groups-present.yml Ansible playbook file.

3. Add the following content to the file:

   ---
   - name: Playbook to ensure SIDs are enabled and users and groups have SIDs
     hosts: ipaserver
     become: no
     gather_facts: no
   
     vars_files:
     - /home/user_name/MyPlaybooks/secret.yml
   
     tasks:
       - name: Enable SID and generate users and groups SIDS
         ipaconfig:
           ipaadmin_password: "{{ ipaadmin_password }}"
           enable_sid: true
           add_sids: true

   The enable_sid variable enables SID generation for future IdM users and groups. The add_sids variable generates SIDs for existing IdM users and groups.

   Note

   When using add_sids: true, you must also set the enable_sid variable to true.

4. Save the file.

5. Run the Ansible playbook. Specify the playbook file, the file storing the password protecting the secret.yml file, and the inventory file:

   $ ansible-playbook --vault-password-file=password_file -v -i inventory sids-for-users-and-groups-present.yml

   When prompted, provide the vault file password.
