Prepare Active Directory for Smart Card Authentication
You might need to perform certain tasks in Active Directory when you implement smart card
authentication.
n
Add UPNs for Smart Card Users on page 25
Because smart card logins rely on user principal names (UPNs), the Active Directory accounts of users
that use smart cards to authenticate in View must have a valid UPN.
n
Add the Root Certificate to Trusted Root Certification Authorities on page 26
If you use a certification authority (CA) to issue smart card login or domain controller certificates, you
must add the root certificate to the Trusted Root Certification Authorities group policy in Active
Directory. You do not need to perform this procedure if the Windows domain controller acts as the
root CA.
n
Add an Intermediate Certificate to Intermediate Certification Authorities on page 26
If you use an intermediate certification authority (CA) to issue smart card login or domain controller
certificates, you must add the intermediate certificate to the Intermediate Certification Authorities
group policy in Active Directory.
n
Add the Root Certificate to the Enterprise NTAuth Store on page 27
If you use a CA to issue smart card login or domain controller certificates, you must add the root
certificate to the Enterprise NTAuth store in Active Directory. You do not need to perform this
procedure if the Windows domain controller acts as the root CA.
Add UPNs for Smart Card Users
Because smart card logins rely on user principal names (UPNs), the Active Directory accounts of users that
use smart cards to authenticate in View must have a valid UPN.
If the domain a smart card user resides in is different from the domain that your root certificate was issued
from, you must set the user’s UPN to the Subject Alternative Name (SAN) contained in the root certificate of
the trusted CA. If your root certificate was issued from a server in the smart card user's current domain, you
do not need to modify the user's UPN.
NOTE You might need to set the UPN for built-in Active Directory accounts, even if the certificate is issued
from the same domain. Built-in accounts, including Administrator, do not have a UPN set by default.
Prerequisites
n
Obtain the SAN contained in the root certificate of the trusted CA by viewing the certificate properties.
n
If the ADSI Edit utility is not present on your Active Directory server, download and install the
appropriate Windows Support Tools from the Microsoft Web site.
Procedure
1 On your Active Directory server, start the ADSI Edit utility.
2 In the left pane, expand the domain the user is located in and double-click CN=Users.
3 In the right pane, right-click the user and then click Properties.
4 Double-click the userPrincipalName attribute and type the SAN value of the trusted CA certificate.
5 Click OK to save the attribute setting.
