module: junos_user
version_added: "2.3"
author: "Peter Sprygada (@privateip)"
short_description: Manage local user accounts on Juniper JUNOS devices
description:
- This module manages locally configured user accounts on remote
network devices running the JUNOS operating system. It provides
a set of arguments for creating, removing and updating locally
defined accounts
extends_documentation_fragment: junos
options:
aggregate:
description:
- The C(aggregate) argument defines a list of users to be configured
on the remote device. The list of users will be compared against
the current users and only changes will be added or removed from
the device configuration. This argument is mutually exclusive with
the name argument.
version_added: "2.4"
aliases: ['users', 'collection']
name:
description:
- The C(name) argument defines the username of the user to be created
on the system. This argument must follow appropriate usernaming
conventions for the target device running JUNOS. This argument is
mutually exclusive with the C(aggregate) argument.
full_name:
description:
- The C(full_name) argument provides the full name of the user
account to be created on the remote device. This argument accepts
any text string value.
role:
description:
- The C(role) argument defines the role of the user account on the
remote system. User accounts can have more than one role
configured.
choices: ['operator', 'read-only', 'super-user', 'unauthorized']
sshkey:
description:
- The C(sshkey) argument defines the public SSH key to be configured
for the user account on the remote system. This argument must
be a valid SSH key
encrypted_password:
description:
- The C(encrypted_password) argument set already hashed password
for the user account on the remote system.
version_added: "2.8"
purge:
description:
- The C(purge) argument instructs the module to consider the
users definition absolute. It will remove any previously configured
users on the device with the exception of the current defined
set of aggregate.
type: bool
default: 'no'
state:
description:
- The C(state) argument configures the state of the user definitions
as it relates to the device operational configuration. When set
to I(present), the user should be configured in the device active
configuration and when set to I(absent) the user should not be
in the device active configuration
default: present
choices: ['present', 'absent']
active:
description:
- Specifies whether or not the configuration is active or deactivated
type: bool
default: 'yes'
version_added: "2.4"
requirements:
- ncclient (>=v0.5.2)
notes:
- This module requires the netconf system service be enabled on
the remote device being managed.
- Tested against vSRX JUNOS version 15.1X49-D15.4, vqfx-10000 JUNOS Version 15.1X53-D60.4.
- Recommended connection is C(netconf). See L(the Junos OS Platform Options,../network/user_guide/platform_junos.html).
- This module also works with C(local) connections for legacy playbooks.
