Citrix Virtual Apps and Desktops

Pass-through authentication and single sign-on with smart cards

Pass-through authentication

Pass-through authentication with smart cards to virtual desktops is supported on user devices running Windows 10, Windows 8, and Windows 7 SP1 Enterprise and Professional Editions.

Pass-through authentication with smart cards to hosted applications is supported on servers running Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, and Windows Server 2008 R2 SP1.

To use pass-through authentication with smart cards hosted applications, ensure you enable the use of Kerberos when you configure Pass-through with smartcard as the authentication method for the site.

Note: The availability of pass-through authentication with smart cards depends on many factors including, but not limited to:

  • Your organization’s security policies regarding pass-through authentication.
  • Middleware type and configuration.
  • Smart card reader types.
  • Middleware PIN caching policy.

Pass-through authentication with smart cards is configured on Citrix StoreFront. See the StoreFront documentation for details.

Single sign-on

Single sign-on is a Citrix feature that implements pass-through authentication with virtual desktop and application launches. You can use this feature in domain-joined, direct-to-StoreFront and domain-joined, NetScaler-to-StoreFront smart card deployments to reduce the number of times that users enter their PIN. To use single sign-on in these deployment types, edit the following parameters in the default.ica file, which is located on the StoreFront server:

  • Domain-joined, direct-to-StoreFront smart card deployments — Set DisableCtrlAltDel to Off
  • Domain-joined, NetScaler-to-StoreFront smart card deployments — Set UseLocalUserAndPassword to On

For more instructions on setting these parameters, see the StoreFront or Citrix Gateway documentation.

The availability of single sign-on functionality depends on many factors including, but not limited to:

  • Your organization’s security policies regarding single sign-on.
  • Middleware type and configuration.
  • Smart card reader types.
  • Middleware PIN caching policy.

Note:

When a user logs on to the Virtual Delivery Agent (VDA) on a machine with an attached smart card reader, a Windows tile may appear representing the previous successful mode of authentication, such as smart card or password. As a result, when single sign-on is enabled, the single sign-on tile may appear. To log on, the user must select Switch Users to select another tile because the single sign-on tile will not work.
