      ipaadmin_password: SomeADMINpassword
      name: testzone.local
      allow_sync_ptr: true
      dynamic_update: true
      dnssec: true
      allow_transfer:
        - 1.1.1.1
        - 2.2.2.2
      allow_query:
        - 1.1.1.1

      skip_overlap_check: true
      skip_nameserver_check: true
      state: present
```


Example playbook to disable a zone:

```yaml

---
- name: Playbook to disable DNS zone
  hosts: ipaserver
  become: true

  tasks:
  - name: Disable zone.
    ipadnszone:
      ipaadmin_password: SomeADMINpassword
      name: testzone.local
      state: disabled
```


Example playbook to enable a zone:
```yaml

---
