Introduction
Smart cards can provide additional security to a thin client network. This paper provides instructions for
configuring a smart card with your HP Compaq t5000 thin client.
Prerequisites
The following items are required to use a smart card with HP Compaq t5000 thin clients:
•Reflex USB V2 Smart Card Reader from Schlumberger.
•Certification Authority (CA): You must prepare smart cards before using them. Each smart card
requires a certificate. To get that certificate on each smart card, you need a certification authority
(CA).
•An Enterprise CA server: To issue smart card certificates, you need an Enterprise CA server.
NOTE: The configuration of the CA is not significant with regard to
simply issuing the smart card logon certificates. However, the
configuration may be important depending on the other uses you plan
for your CA.
Installing a Certificate Authority (CA)
To install a CA, perform the following steps:
1. Log on as a member of the Enterprise Admins group.
2. Select Start > Control Panel > Add/Remove Programs and click Add/Remove Windows
Components.
3. From the list of Windows components, select the Certificate Services option and follow the wizard to
install. A message warns that after installing, a machine name or domain membership cannot be
changed due to the binding of the machine name to the CA information stored in the Active Direc-
tory. After you ensure that the proper machine name and domain membership are configured click
Yes, and click Next.
4. From the CA Type selection box ensure that you are installing an Enterprise root CA and click Next.

3
5. From the CA Identifying Information box, enter a name for your CA and click Next.
6. From the Certificate Database Settings dialog box, leave the default settings (unless you know that
you want to change them) and click Next. You'll need the CD-ROM or installation files.
7. If Internal Information Services is currently running, you will be prompted to stop the service tempo-
rarily. Click Yes.
8. If you don't have Internet Information Services (IIS) installed, you'll be prompted to install IIS to get
web enrollment working. If you don't plan to do any web enrollment, click OK and ignore the prompt.
NOTE: Active Server Pages must be enabled to allow Certificate
Services to provide web enrollment service. Enabling ASPs is a
potential security risk. If you do not plan web enrollment services, click
No when prompted. If you click No, IIS must be manually reconfigured
later to enable this functionality.
9. Click Finish.

Creating a Smart Card Logon Certificate Template
You will need to create a smart card logon certificate template. To create the certificate template, perform
the following steps:
1. Create an MMC with the following snap-ins:
• Active Directory Users and Computers
• Certification Authority
• Certificate Templates
2. Click Certificate Templates and look for the Smartcard Logon certificate in the right-hand pane.
3. Right click Certificate Templates and click Manage.
4. Right-click the Smartcard Logon template and select Duplicate Template.

5
5. A Properties of New Template dialog box will appear. Give the new template a name. Be sure to
select Publish Certificate in Active Directory if the box isn't already checked.

6
6. Click the Request Handling tab and then select Signature and Smartcard Logon in the Purpose drop-
down list. If you want the user to be prompted to insert a smart card during logon, select the option
Prompt the User During Enrollment.
7. From the Properties of New Templates dialog box, click the CSPs button near the bottom to open the
CSP Selection dialog box, where you can select the appropriate cryptographic service provider
(CSP).

7
NOTE: You cannot randomly select a CSP. What you select affects
what the user sees on the other end. For example, if selecting the
Schlumberger Cryptographic Service Provider, the user is prompted to
insert a Schlumberger smart card on the client side. Select only the
applicable CSP(s) for your smart cards. This process is easier if you
have only one type of smart card and reader. If you have more than
one smart card type, you'll have to select multiple CSPs.
8. From the Properties of the New Template box, click the Security tab. If you want to allow all users in
your Domain Users group to receive certificates during logon, you must add them to the Access Con-
trol List (ACL) for this template. Be sure to give them the rights to Read and Enroll.
9. Click OK. The template is ready.

8
Issuing the Certificate
Now that you have the smart card logon template duplicated, you need to issue it from the CA. To issue
the certificate perform the following steps:
1. Expand the Certification Authority object in your MMC.
2. Expand your CA name.
3. Right-click Certificate Templates.
4. Click New, and then click Certificate Template to Issue.
5. Locate and select your newly created and configured certificate and click OK. The new certificate
appears in the right-hand pane.

Forcing a Smart Card Logon
Administrators can modify users’ account properties to require smart cards for interactive logons. With
this feature, users cannot log onto a thin client in your network without a smart card. To configure this
option, perform the following steps:
1. From the Group Policy Editor window, select Group Policy Editor > Software Settings >
Account Policies > Local Policies > Security Options.
2. Locate the “Interactive Logon: Require smartcard” policy.
3. Right-click the ”Require smartcard” policy and click Enable.
If you require smart card logon for all your network users, you can scour your domain for any remaining
passwords that cannot be replaced. For example, some service accounts (those for Internet Information
Server, Exchange Server, backup programs, etc.) still require passwords, so you still need a good
password policy to secure those accounts. Because you can control these passwords, you can create a
strong password policy to further secure your network.
