Enhanced domain pass-through for single sign-on
Enhanced domain pass-through for single sign-on uses Kerberos to enable single sign-on into Citrix Workspace app and into the virtual apps and desktop sessions when using Active Directory (AD) joined client devices and Citrix StoreFront.
Note:
This feature is not supported on 32-bit operating systems.
This feature is a replacement for the legacy pass-through authentication feature based on the Citrix Single Sign-on Service (ssonsvr.exe).
The legacy domain pass-through (SSON) authentication requires enabling the Enable MPR notifications for the System policy in the Group Policy Object template. Enhanced Domain Passthrough, however, allows pass-through authentication without needing to enable this policy.
