module: cnos_user
author: "Anil Kumar Muraleedharan (@amuraleedhar)"
short_description: Manage the collection of local users on Lenovo CNOS devices
description:
- This module provides declarative management of the local usernames
configured on Lenovo CNOS devices. It allows playbooks to manage
either individual usernames or the collection of usernames in the
current running config. It also supports purging usernames from the
configuration that are not explicitly defined.
options:
aggregate:
description:
- The set of username objects to be configured on the remote
Lenovo CNOS device. The list entries can either be the username
or a hash of username and properties. This argument is mutually
exclusive with the C(name) argument.
aliases: ['users', 'collection']
name:
description:
- The username to be configured on the remote Lenovo CNOS
device. This argument accepts a string value and is mutually
exclusive with the C(aggregate) argument.
configured_password:
description:
- The password to be configured on the network device. The
password needs to be provided in cleartext and it will be encrypted
on the device.
Please note that this option is not same as C(provider password).
update_password:
description:
- Since passwords are encrypted in the device running config, this
argument will instruct the module when to change the password. When
set to C(always), the password will always be updated in the device
and when set to C(on_create) the password will be updated only if
the username is created.
default: always
choices: ['on_create', 'always']
role:
description:
- The C(role) argument configures the role for the username in the
device running configuration. The argument accepts a string value
defining the role name. This argument does not check if the role
has been configured on the device.
aliases: ['roles']
sshkey:
description:
- The C(sshkey) argument defines the SSH public key to configure
for the username. This argument accepts a valid SSH key value.
purge:
description:
- The C(purge) argument instructs the module to consider the
resource definition absolute. It will remove any previously
configured usernames on the device with the exception of the
`admin` user which cannot be deleted per cnos constraints.
type: bool
default: 'no'
state:
description:
- The C(state) argument configures the state of the username definition
as it relates to the device operational configuration. When set
to I(present), the username(s) should be configured in the device active
configuration and when set to I(absent) the username(s) should not be
in the device active configuration
default: present
choices: ['present', 'absent']
