Smart card authentication
Supported on: All Citrix Workspace supported platforms
Description
Use this policy to control how the client uses smart cards attached to the client device. When enabled, this policy allows the remote server to access smart cards attached to the client device for authentication and other purposes. When disabled, the server cannot access smart cards attached to the client device. Troubleshooting: When using smart cards in a Citrix environment, the smart card device driver must be installed on the server. When using a different operating system on the client machine, it may be necessary to ensure that the smart card device drivers in use interoperate correctly.

Enabled: SmartCardAllowed = *
Disabled: SmartCardAllowed = false
REG Builder
BETAConfigure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.
These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
