Client devices that use a smart card for user authentication must meet certain requirements.
Client Hardware and Software Requirements
An iOS 8.4.1 or later operating system is required.
Each client device that uses a smart card for user authentication must have the following hardware and software:
A compatible smart card reader.
Alternatively, you can use the Purebred app for derived credentials. To use derived credentials, you must also create a virtual smart card in Horizon Client.
Product-specific application drivers
Users that authenticate with smart cards must have a physical or virtual smart card, and each smart card must contain a user certificate.
Remote Desktop and Application Software Requirements
A Horizon administrator must install product-specific application drivers on the remote desktops or RDS host.
Horizon Client for iOS supports using smart cards with remote desktops that have Windows 7, Windows Vista, Windows XP, Windows 8.1, Windows 10, and Windows Server 2008 R2 guest operating systems. For published desktops and remote applications, the Windows Server 2008 R2 and Windows Server 2012 R2 operating systems are supported.
Enabling the Username Hint Field in Horizon Client
In some environments, smart card users can use a single smart card certificate to authenticate to multiple user accounts. Users enter their user name in the Username hint field during smart card sign-in.
To make the Username hint field appear on the Horizon Client login dialog box, you must enable the smart card user name hints feature for the Connection Server instance in Horizon Administrator. The smart card user name hints feature is supported only with Horizon 7 version 7.0.2 and later servers and agents. For information about enabling the smart card user name hints feature, see the View Administration document.
If your environment uses an Unified Access Gateway appliance rather than a security server for secure external access, you must configure the Unified Access Gateway appliance to support the smart card user name hints feature. The smart card user name hints feature is supported only with Unified Access Gateway 2.7.2 and later. For information about enabling the smart card user name hints feature in Unified Access Gateway, see the Deploying and Configuring Unified Access Gateway document.
Horizon Client still supports single-account smart card certificates when the smart card user name hints feature is enabled.
Additional Smart Card Authentication Requirements
In addition to meeting the smart card requirements for Horizon Client systems, other Horizon components must meet certain configuration requirements to support smart cards.
Connection Server and security server hosts
An administrator must add all applicable Certificate Authority (CA) certificates for all trusted user certificates to a server truststore file on the Connection Server host or security server host. These certificates include root certificates and must include intermediate certificates if the user's smart card certificate was issued by an intermediate certificate authority.
For information about configuring Connection Server to support smart card use, see the View Administration document.
For information about tasks that an administrator might need to perform in Active Directory to implement smart card authentication, see the View Administration document.
