Citrix ADC
ThinOS supports Citrix Application Delivery Controller (ADC), formerly known as Citrix NetScaler. The following authentication
methods are supported on ThinOS:
Lightweight Directory Access Protocol (LDAP)
RSA
DUO
SMS PASSCODE
Native OTP
Federated Authentication Service with Azure active directory
OKTA
Timeout is enabled for Citrix ADC login by default. To disable the timeout, go to Advanced > Broker Settings > Citrix Virtual
Apps and Desktops Settings from the Wyse Management Suite policy settings or the Admin Policy Tool, and disable the
Netscaler/ADC Login Timeout option.
By default, the NetScaler/ADC Authentication using web-based login option is enabled for the applicable Citrix ADC server.
To disable the web-based login, go to Advanced > Broker Settings > Citrix Virtual Apps and Desktops Settings from
the Wyse Management Suite policy settings or the Admin Policy Tool, and disable the Netscaler/ADC Authentication using
web-based login option.
NOTE: Dell technologies recommends that you do not disable the Netscaler/ADC Authentication using web-based
login option.
Citrix two-factor authentication
ThinOS supports Citrix two-factor authentication that authenticates the identity of the user twice before granting access,
adding an extra level of security.
For local authentication, there must be a user profile that is created in the Citrix ADC database. For external authentication,
the username and password that is entered must be the same as registered in the authentication server. After a successful
validation of the username and password, the user is requested for another level of authentication.
ThinOS supports LDAP, RSA+LDAP, SMS Passcode, DUO, OKTA, and Azure MFA authentications by default. The user must only
provide the Citrix ADC gateway address.
To log in to NetScaler Gateway that uses LDAP with RSA authentication, you must select LDAP+RSA in the Wyse
Management Suite policy. You can also go to Admin Policy Tool and configure the NetScaler/ADC Authentication Method
option in the Citrix Broker Settings window.
For specific users who want to use Citrix ADC authentication methods, such as RSA, it is recommended that you configure the
NetScaler/ADC Authentication Method with RSA either using the Wyse Management Suite policy or Admin Policy Tool.
For specific users who want to use Citrix ADC authentication methods, such as LDAP with MFA, it is recommended that you
configure the NetScaler/ADC Authentication Method with LDAP either using the Wyse Management Suite policy or the
Admin Policy tool.
Configure Citrix ADC using LDAP and RSA
About this task
This section describes how to configure the Citrix ADC (formerly NetScaler) using LDAP and RSA authentication.
Steps
1. Go to NetScaler > NetScaler Gateway > Virtual Servers, and click Edit.
2. Set the primary and secondary authentications based on the following scenarios:
If you use LDAP and RSA login, ensure that the primary authentication is LDAP and secondary authentication is RADIUS.
You must also ensure that the NetScaler Gateway Authentication Method in the Wyse Management Suite policy or
the Admin Policy Tool is configured as LDAP+RSA.
If you use RSA and LDAP login, ensure that the primary authentication is RADIUS and secondary authentication is LDAP.
If you use only LDAP login, ensure that the primary authentication is LDAP and secondary authentication is none.
