bigip_device_auth – Manage system authentication on a BIG-IP

New in version 2.7.

Synopsis

  • Manage the system authentication configuration. This module can assist in configuring a number of different system authentication types. Note that this module can not be used to configure APM authentication types.

Requirements

The below requirements are needed on the host that executes this module.

  • f5-sdk >= 3.0.16

Parameters

Parameter Choices/Defaults Comments
authentication
-
    Choices:
  • use-first-server
  • use-all-servers
Specifies the process the system employs when sending authentication requests.
When use-first-server, specifies that the system sends authentication attempts to only the first server in the list.
When use-all-servers, specifies that the system sends an authentication request to each server until authentication succeeds, or until the system has sent a request to all servers in the list.
This parameter is supported by the tacacs type.
password
- / required
The password for the user account used to connect to the BIG-IP.
You may omit this option by setting the environment variable F5_PASSWORD.

aliases: pass, pwd
protocol_name
-
    Choices:
  • lcp
  • ip
  • ipx
  • atalk
  • vines
  • lat
  • xremote
  • tn3270
  • telnet
  • rlogin
  • pad
  • vpdn
  • ftp
  • http
  • deccp
  • osicp
  • unknown
Specifies the protocol associated with the value specified in service_name, which is a subset of the associated service being used for client authorization or system accounting.
Note that the majority of TACACS+ implementations are of protocol type ip, so try that first.
provider
-
added in 2.5
Default:
null
A dict object containing connection details.
password
- / required
The password for the user account used to connect to the BIG-IP.
You may omit this option by setting the environment variable F5_PASSWORD.

aliases: pass, pwd
server
- / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
-
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
ssh_keyfile
-
Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports.
You may omit this option by setting the environment variable ANSIBLE_NET_SSH_KEYFILE.
timeout
-
Default:
10
Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
transport
- / required
    Choices:
  • rest
  • cli ←
Configures the transport connection to use when connecting to the remote device.
user
- / required
The username to connect to the BIG-IP with. This user must have administrative privileges on the device.
You may omit this option by setting the environment variable F5_USER.
validate_certs
boolean
    Choices:
  • no
  • yes ←
If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.
You may omit this option by setting the environment variable F5_VALIDATE_CERTS.
secret
-
Secret key used to encrypt and decrypt packets sent or received from the server.
Do not use the pound/hash sign in the secret for TACACS+ servers.
When configuring TACACS+ auth for the first time, this value is required.
server
- / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
-
added in 2.2
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
servers
-
Specifies a list of the IPv4 addresses for servers using the Terminal Access Controller Access System (TACACS)+ protocol with which the system communicates to obtain authorization data.
For each address, an alternate TCP port number may be optionally specified by specifying the port key.
If no port number is specified, the default port 49163 is used.
This parameter is supported by the tacacs type.
address
-
The IP address of the server.
This field is required, unless you are specifying a simple list of servers. In that case, the simple list can specify server IPs. See examples for more clarification.
port
-
Default:
49163
The port of the server.
service_name
-
    Choices:
  • slip
  • ppp
  • arap
  • shell
  • tty-daemon
  • connection
  • system
  • firewall
Specifies the name of the service that the user is requesting to be authorized to use.
Identifying what the user is asking to be authorized for, enables the TACACS+ server to behave differently for different types of authorization requests.
When configuring this form of system authentication, this setting is required.
Note that the majority of TACACS+ implementations are of service type ppp, so try that first.
state
-
    Choices:
  • absent
  • present ←
The state of the authentication configuration on the system.
When present, guarantees that the system is configured for the specified type.
When absent, sets the system auth source back to local.
type
-
    Choices:
  • tacacs
  • local
The authentication type to manage with this module.
Take special note that the parameters supported by this module will vary depending on the type that you are configuring.
This module only supports a subset, at this time, of the total available auth types.
update_secret
-
    Choices:
  • always ←
  • on_create
always will allow to update secrets if the user chooses to do so.
on_create will only set the secret when a use_auth_source is yes and TACACS+ is not currently the auth source.
use_for_auth
boolean
    Choices:
  • no
  • yes
Specifies whether or not this auth source is put in use on the system.
user
- / required
The username to connect to the BIG-IP with. This user must have administrative privileges on the device.
You may omit this option by setting the environment variable F5_USER.
validate_certs
boolean
added in 2.0
    Choices:
  • no
  • yes ←
If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.
You may omit this option by setting the environment variable F5_VALIDATE_CERTS.

Notes

Note

  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.
  • Requires the f5-sdk Python package on the host. This is as easy as pip install f5-sdk.
  • Requires BIG-IP software version >= 12.
  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
