Passthrough authentication is not working on a Terminal Server

Environment

Novell ZENworks 10 Configuration Management
Windows 2003 SP2
Citrix Presentation Server 4.5

Situation

When a client connects to the Terminal Server, the agent is not automatically logging in to the ZCM server after session login.

Resolution

This is fixed in version 10.0.3 - see KB 3486285 "Updates to ZENworks 10 Configuration Management" which can be found at https://www.novell.com/support
Workaround:
Check the registry settings for GINA. Note the existing settings prior to making a change in case there is a problem with the change so they can be set back.
After installing the ZCM agent the following registry key needs to changed to allow passthrough authentication:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon]
"CTXGinaDLL"="NWGINA.DLL"
"GinaDLL"="CTXGINA.DLL"
