Introduction
Smart cards can strengthen user authentication in a corporate network by offering strong, 2-factor authen-
tication to offset weak passwords or cumbersome authentication policies requiring frequent password
changes. This paper provides instructions for configuring a smart card with your HP Compaq t5720 Thin
Clients and HP blade PCs. This white paper is not intended as a comprehensive overview of ActivCard
smart card technology and does not address detailed setup of network infrastructure settings such as
DHCP, DNS, Active Directory, IIS or the HP Session Allocation Manager (SAM) or other Windows load
balancing concerns.
This white paper assumes working knowledge for configuration of Thin Client Enhanced Write Filter
(EWF) and acknowledged RDP enablement settings at both server and client.

Client Software Configuration
Installing ActivClient PKI Only
The Setup Deployment chapter of the Resource Kit provided by ActivIdentity discusses how to deploy
ActivClient using standard methods.
The ActivClient PKI Only 6.0 allows the user (based on privileges) or the Administrator to change and ver-
ify the PINs, view card and system information, and register certificates. HP does not support and has not
validated any ActivClient Enterprise class smart card provisioning solutions. For administrative smart card
provisioning, HP recommends that you contact ActivIdentity for a list of Enterprise class life cycle manage-
ment tools and access to their ActivClient Resource Kit to provide administrative management of client
smart card usage. Any client-based provisioning software installed may require write filter commit on the
HP thin client.
An illustration of Administration provisioning is initializing a card and having to keep track of the “unlock
code” manually or having to manually download certificates to the card. The remainder of this guide out-
lines installation of minimal client options, ActivDirectory management of certificates, and assumes the
Administrator manually tracks card unlock codes. For large scale rollout or deployment options, please
consult with ActivIdentity during your software purchase or consider the ActivClient to be managed by the
card user (a client-user based provisioned model would require normal setup.msi installation or modifica-
tion to the minimal installation parameters listed below for greater client-based card management con-
trol).
These identified services typically get installed with defaults provided with a standard ActivClient PKI
Only.msi installation:
•Pin-initialization
•Advanced Configuration Manager
•Advanced Diagnostics
•Digital Certificates Services (node)
•Entrust Entelligence Desktop Solution Support
•User Console
•Troubleshooting
Installation of ActivClient PKI Only 6.0 requires changing the thin client RAMDisk size to 64MB as well as
changes to the Windows environmental variables on an thin client. These changes must be made from an
administrative privileged account.
NOTE: During the software installation, the reader should not contain a smart card.
NOTE: Close all open Windows programs and applications.
NOTE: You will be prompted to reboot after clicking Apply to the RamDisk size change. Commit (EWF)
data to the volume after completing the installation or changes will be lost on the next reboot.
NOTE: HP deployment solutions such as Altiris client manager do not require RAMDisk size adjustments
or modification of environmental variables.

6
As mentioned above, the first installation step is to modify the thin client’s RAMDisk size from default set-
tings to 64 MB. Make note of the default setting so that it can be restored after installation is complete.
To change RAMDisk size, click Start > Control Panel > HP RAMDisk Manager.
Next, modify the thin client TEMP and TMP environmental variables to a location that can support the
.msi user installation package size. To change environmental variables, click Start > Control Panel >
System Properties > Advanced tab > Environmental Variables.

7
Once the environmental variables have been changed, right-click on the EWF icon on the taskbar and
select Commit.
NOTE: The environmental variables should be changed back to default settings after installation package
has been installed, and then the write filter changes must again be committed.
Installation of ActivClient base services and CSP is required on the client for smart card support. Due to
t5720 flash drive space constraints, recommended minimum installation parameters are outlined by using
the following install command-line parameter (please consult ActivIdentity Resource Kit documentation for
further customizable install parameters and deployment capabilities):
msiexec /i "ActivClient PKI Only.msi" BASEREQ=1 CSPREQ=1 DEVICEREQ=1 KEY-
SIMREQ=1 RAANDOTPREQ=1 OUTLOOKREQ=-1 PKCSREQ=-1 PCMCIAV2REQ=-1 USBV2REQ=-
1USBV3REQ=-1 ADVCONFMANREQ=-1 ADVDIAGREQ=-1 CMSREQ=-1 PIVAPIREQ=-1 ACSAGEN-
TREQ=-1 USERCONSREQ=-1 AUTOUPDATEREQ=-1 DOCREQ=1 DOCCACREQ=-1 PININITTOOL-
REQ=-1 PINCHANGETOOLREQ=-1 TROUBLESHOOTING_ENABLED=1
The previous command includes installation of:
•Base Services
•Microsoft CAPI support
•Device Drivers
•Remote Access & OneTime Password Services
Applying an advanced configuration default template to clients that meets Government Smart Card
Interoperability Specifications (see http://smartcard.nist.gov/ for details on GSC-IS) is possible via group
policy objects, registry editors, or ActivIdentity Advanced Configuration Manager software included with
ActivClient PKI Only software CD. For specifics about implementing default templates, refer to the section
about product customization in the ActivClient Customization and Deployment Guide included in the
ActivClient Resource Kit.
NOTE: To remove the ActivIdentity software from an HP Compaq t5720 Thin Client, you must use
MSIEXEC /x “ActivClient PKI Only.msi” command. Manual execution of the MSI or through
the product CD requires usage of add/remove programs which is not available on HP thin client systems.

8
Initializing the smart card
Use the following procedure on blank smart cards or cards which contain a standalone profile that need
to be re-initialized. To initialize your PIN using the PIN Initialization Tool:
1. Go to Start > Programs > ActivIdentity > ActivClient and select PIN Initialization Tool.
-or-
Right-click the ActivClient Agent icon located on the Windows taskbar and select PIN
Initialization Tool from the right-click menu.
2. Follow the PIN Initialization wizard.
Note: PIN Initialization tool profile. ActivClient also supports a profile specifically created for the PIN
Initialization tool
3. Enter your PIN code, confirm it, and then click Next.
NOTE: The PIN code must conform with the PIN rules displayed by the tool. All the rules must display a
green check for the PIN Initialization Tool to let you move forward.
4. In the case of standalone smart cards (with an unlock code), you must enter a PIN or unlock code.
When the initialization is complete, the Finish window is displayed.
5. In the case where an unlock code is displayed, write it down in a secure location and click Finish to
close the window.
NOTE: If the card is already initialized, the following warning message is displayed:
ActivClient detected that your card is already initialized. Your card
will be reinitialized and any content present on the card (including
private keys) will be permanently deleted.
NOTE: CAC is a Common Access Card issued by the United States Department of Defense. Displays an
expiration date for the card and the card’s certificate. PIV is a Personal Identity Verification Card issued
by the United States Department of Defense. Displays an expiration date for the card and the card’s cer-
tificate. By design a CAC card CANNOT be initialized by the PIN Initialization tool.
