Set Up RADIUS or TACACS+ Authentication

Create a server profile.
The server profile identifies the external authentication service and instructs the firewall how to connect to that authentication service and access the authentication credentials for your users.
If you want to Enable Delivery of VSAs to a RADIUS Server, you must create a RADIUS server profile.
Select
Device
Server Profiles
, and then select the profile type (
RADIUS
or
TACACS+
).
Add
a new RADIUS or TACACS+ server profile.
Enter a
Profile Name
, such as
GP-User-Auth
.
If this profile is for a firewall with multiple virtual systems capability, select a virtual system or
Shared
as the
Location
where the profile is available.
Configure the following
Server Settings
:
Timeout (sec)
—The number of seconds before a server connection request times out due to lack of response from the authentication server.
Authentication Protocol
—The protocol used to connect to the authentication server. Options include
CHAP
,
PAP
,
PEAP-MSCHAPv2
,
PEAP with GTC
, or
EAP-TTLS with PAP
.
If you configure
PEAP-MSCHAPv2
(Protected Extensible Authentication Protocol Microsoft Challenge Handshakie Authentication Protocol version 2) as the authentication protocol, remote users can change their RADIUS or Active Directory (AD) passwords through the GlobalProtect app when their password expires or a RADIUS/AD administrator requires a password change at the next login.
(
RADIUS Only
)
Retries
—The number of times the firewall attempts to connect to the authentication server before dropping the request.
(
TACACS+ only
)
Use single connection for all authentication
—Option that allows all TACACS+ authentication requests to occur over a single TCP session rather than separate sessions for each request.
Click
Add
in the
Servers
area, and then enter the following information for connecting to the authentication server:
Name
RADIUS
or
TACACS+
Server
(IP address or FQDN of the server)
Secret
(shared secret that enables the authentication service to authenticate the firewall)
Port
Click
OK
to save the server profile.
(
Optional
) Create an authentication profile.
The authentication profile specifies the server profile that the portal or gateways use when they authenticate users. On a portal or gateway, you can assign one or more authentication profiles in one or more client authentication profiles. For information on how an authentication profile within a client authentication profile supports granular user authentication, see Configure a GlobalProtect Gateway and Set Up Access to the GlobalProtect Portal.
To enable users to connect and change their own expired passwords without administrative intervention, consider using Remote Access VPN with Pre-Logon.
Select
Device
Authentication Profile
, and then
Add
a new profile.
Enter a
Name
for the profile.
Select the
Authentication
Type
(
RADIUS
or
TACACS+
).
Select the RADIUS or TACACS+ authentication
Server Profile
that you created in step 1 from the drop-down.
(
RADIUS only
) Enable
Retrieve user group from RADIUS
if you want to include this information in the authentication profile.
Specify the
User Domain
and
Username Modifier
. The endpoint combines these values to modify the domain/username string that a user enters during login. The endpoint uses the modified string for authentication and the
User Domain
value for User-ID group mapping. Modifying user inputs is useful when the authentication service requires domain/username strings in a particular format and but you do not want to rely on users entering the domain correctly. You can select from the following options:
To send the unmodified user input, leave the
User Domain
blank (the default) and set the
Username Modifier
to the variable
%USERINPUT%
(the default).
To prepend a domain to the user input, enter a
User Domain
and set the
Username Modifier
to
%USERDOMAIN%\%USERINPUT%
.
To append a domain to the user input, enter a
User Domain
and set the
Username Modifier
to
%USERINPUT%@%USERDOMAIN%
.
If the
Username Modifier
includes the
%USERDOMAIN%
variable, the
User Domain
value replaces any domain string that the user enters. If the
User Domain
is blank, the device removes any user-entered domain string.
On the
Advanced
tab,
Add
an
Allow List
to select the users and user groups that are allowed to authenticate with this profile. The
all
option allows every user to authenticate with this profile. By default, the list has no entries, which means no users can authenticate.
Click
OK
.
Commit
the configuration.
