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.

Obtain the SAN contained in the root certificate of the trusted CA by viewing the certificate properties.

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.
