    - Module to manage permissions of users/groups in oVirt/RHV.
options:
    role:
        description:
            - Name of the role to be assigned to user/group on specific object.
        default: UserRole
    state:
        description:
            - Should the permission be present/absent.
        choices: [ absent, present ]
        default: present
    object_id:
        description:
            - ID of the object where the permissions should be managed.
    object_name:
        description:
            - Name of the object where the permissions should be managed.
    object_type:
        description:
            - The object where the permissions should be managed.
        choices:
        - cluster

        default: vm
    user_name:
        description:
            - Username of the user to manage. In most LDAPs it's I(uid) of the user,
              but in Active Directory you must specify I(UPN) of the user.
            - Note that if user does not exist in the system this module will fail,
              you should ensure the user exists by using M(ovirt_users) module.
    group_name:
        description:
            - Name of the group to manage.
            - Note that if group does not exist in the system this module will fail,
               you should ensure the group exists by using M(ovirt_groups) module.
    authz_name:
        description:
            - Authorization provider of the user/group.
        required: true
        aliases: [ domain ]
    namespace:
        description:
            - Namespace of the authorization provider, where user/group resides.
    quota_name:
        description:
            - Name of the quota to assign permission. Works only with C(object_type) I(data_center).

EXAMPLES = '''
# Examples don't contain auth parameter for simplicity,

    user_name: user1
    authz_name: example.com-authz
    object_type: vm
    object_name: myvm
    role: UserVmManager

- name: Remove permission from user
  ovirt_permission:
    state: absent
    user_name: user1
    authz_name: example.com-authz
    object_type: cluster
    object_name: mycluster
    role: ClusterAdmin

- name: Assign QuotaConsumer role to user
  ovirt_permissions:
    state: present
    user_name: user1
    authz_name: example.com-authz
    object_type: data_center
    object_name: mydatacenter
    quota_name: myquota
