n Add the Root Certificate to Trusted Root Certification Authorities
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
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.
Add UPNs for Smart Card Users
Because smart card logins rely on user principal names (UPNs), the Active Directory accounts of
users and administrators that use smart cards to authenticate in Horizon 7 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.
Add the Root Certificate to the Enterprise NTAuth Store
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.
