DESCRIPTION
To authenticate BIG-IP system users when their authentication data is stored on a remote TACACS+ server, you create a
TACACS+ configuration object, and then activate the object.
To configure TACACS+ authentication for BIG-IP system users:
1. Use the tacacs component in the auth module to configure a TACACS+ configuration object.
2. To activate TACACS+ authentication for BIG-IP system users, run the following command sequence: modify / auth source
type tacacs
EXAMPLES
create tacacs bigip_tacacs_auth servers add {my_tacacs_server}
Creates a TACACS+ configuration object named bigip_tacacs_auth.
delete tacacs bigip_tacacs_auth
Deletes the TACACS+ configuration object named bigip_tacacs_auth.
OPTIONS
accounting
If multiple TACACS+ servers are defined and pluggable authentication module (PAM) session accounting is enabled, sends
accounting start and stop packets to the first available server or to all servers. The default value is send-to-first-
server.
Possible values are:
send-to-all-servers
The system sends accounting start and stop packets to all servers.
send-to-first-server
The system sends accounting start and stop packets to the first available server.
app-service
Specifies the name of the application service to which the TACACS+ configuration object belongs. The default value is
none. Note: If the strict-updates option is enabled on the application service that owns the object, you cannot modify
or delete the TACACS+ configuration object. Only the application service can modify or delete the TACACS+
configuration object.
authentication
Specifies the process the system employs when sending authentication requests. The default value is use-first-server.
Possible values are:
use-all-servers
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.
use-first-server
The system sends authentication requests to only the first server in the list.
debug
Enables syslog-ng debugging information at the LOG DEBUG level. F5 Networks does not recommend this option for normal
use. The default value is disabled.
description
User defined description.
encryption
Enables or disables encryption of TACACS+ packets. F5 Networks recommends this option for normal use. The default
value is enabled.
glob Displays the items that match the glob expression. See help glob for a description of glob expression syntax.
name Specifies a unique name for the component. This option is required for the commands create and modify.
partition
Displays the administrative partition within which the component resides.
protocol
Specifies the protocol associated with the value specified in the service option, which is a subset of the associated
service being used for client authorization or system accounting.
regex
Displays the items that match the regular expression. The regular expression must be preceded by an at sign (@[regular
expression]) to indicate that the identifier is a regular expression. See help regex for a description of regular
expression syntax.
secret
Sets the secret key used to encrypt and decrypt packets sent or received from the server. This option is required.
servers
Specifies the host name or IPv4 address of the TACACS+ server. For each server, a port may optionally be specified in
the format hostname:port or IPv4:port. If no port is specified, the default port 49 is used. This option is required.
service
Specifies the name of the service that the user is requesting to be authenticated to use. Identifying the service
enables the TACACS+ server to behave differently for different types of authentication requests. This option is
required.
timeout Specifies the connect timeout in seconds. The default value is 10 seconds. Zero indicates no timeout.
