Enabling Smart Card Authentication Using Linux Clients

Smart card authentication is supported while connecting from Linux Clients to Windows agents. The following section contains information on system requirements, limitations, agent setup, and client setup.

General Requirements

Smart Card Certificate Requirements

The smart card certificate prerequisites are as follows:

• Key usage is set to digital signature

• The Subject common name and subject alternative name (other name) are defined

• Enhanced key usage must include client authentication and/or smart card logon

• Key length is not be larger than 2048 bit

Tested Smart Card Readers

The following smart card readers have been tested:

• Belkin USB Smart Card Reader (F1DN008U)

• Identiv SCR3310 USB Contact Smart Card Reader

Tested Smart Card Models

The following smart card models have been tested:

Notes

• Smart Card authentication can only be enabled or disabled during installation. If the Anyware agent has already been installed, re-install the software using the agent setup instructions.

• The interface-driven installer for the Graphics Agent for Windows cannot enable this functionality. You must use the scripted (silent) installer.

• At present, only simultaneous configuration of a single card and single reader is supported.

• While in a PCoIP session, the remote desktop's Device Manager will show two identical smart cards. This is expected and does not affect the session.

Known Limitations

• The Interactive logon: Smart card removal behavior is not supported during sessions authenticated using smart cards.

• Elliptic Curve Cryptography (ECC) Certificates are not supported.

• When authenticated using smart cards, Anyware Clients cannot recognize HP Digital Badges.

• Concurrent users cannot log on to agent machines using the same smart card for authentication.

• Smart cards having multiple certificates allow only one user to log on at a time. Others users must wait until the current users logs off before attempting to log on.

Agent Setup

1. Make sure that you downloaded Anyware Agent 24.03 or later to the remote machine.

2. Connect to the remote machine via RDP.

3. On the remote machine, install the Graphics Agent for Windows using the /InstallVSCReader argument.

   • Windows BAT: Open a Windows command line tool and enter the following:

   start /WAIT <path_to_installer> /S /NoPostReboot /InstallVSCReader
   echo %ERRORLEVEL%
   

   where <path_to_installer> is the system filepath of the installer file.

   • Windows PowerShell: Open a PowerShell window and enter the following:

     $process = Start-Process -FilePath <path_to_installer> -ArgumentList "/S /NoPostReboot /InstallVSCReader _?<path_to_installer>" -Wait -PassThru; $process.ExitCode
     

   where <path_to_installer> is the system filepath of the installer file. Note that this argument is used twice.

4. Configure the Graphics Agent for Windows license information, as described here.

5. Install the ActivClient middleware (available from your SmartCard vendor) on the host machine. Skip this step if you are using Yubikey 5C or Yubikey 5 NFC.

   Middleware installation notes

   • ActivClient middleware must be installed in a console session.
   • To prevent conflicts, only one middleware should be installed.

6. Reboot the remote machine.

Client Setup

1. Make sure that you downloaded Anyware Linux Client version 24.03 or later on the client machine.

2. Configure the client machine to connect to the agent machine. Follow the instructions in the topic in the Anyware Linux Client guide.

3. Plug the smart card reader into the Client machine, and use your smart card for authenticating the PCoIP session. For instructions on using the smart card to authenticate PCoIP sessions, consult "Using Smart Card Authentication to Connect to a Session" in the topic Connecting to an Agent Machine.

Removing Smart Card Support

In order to remove support for Smart Card Authentication, uninstall the agent and then re-install it without using the /InstallVSCReader option.

Troubleshooting Issues

Sometimes, you might encounter the following issues on Windows agents running on Windows Server 2022:

• When Single Sign-On (SSO) is enabled, smart cards are not displayed in the Device Manager list on the remote agent
• When SSO is disabled, smart cards do not appear on locked screens, and therefore, users cannot use them to unlock the screens

To resolve these issues, make sure that the correct driver is in use for the smart card readers.
