Question

How to cascade Sophos SafeGuard Disk Encryption and Cisco VPN client?

Answer

Note: This article is based on the assumption that no other software products are installed which also bring their own GINA (i.e. Novell client, PCAnywhere, etc.)

There are two basic ways to solve this problem.

A quick way if Sophos SafeGuard Disk Encryption is already installed is to enter/edit a registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Utimaco\SGLogon]
"GinaDLLRepair"=dword:00000000

(by default it is 00000001) and then install the Cisco software.

This will make the Cisco Gina the primary Gina, which will (dependant on the quality of the Cisco installation software) refer to the SGGINA.DLL, which refers to the MSGINA.DLL, which completes the chain.

Alternatively (depending on whether the version (?) of the Cisco software still supports this), you could, after the installation of both packages, try and modify the registry as follows:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"GinaDLL"="SGGINA.DLL"

[HKEY_LOCAL_MACHINE\SOFTWARE\UTIMACO\SGLogon]
"Original Gina"="CSGina.dll"

[HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems\VPN Client]
"PreviousGinaPath"="MSGINA.DLL"

This makes the SGGINA the primary one, which refers to the Cisco GINA, which refers to the MSGINA, which completes the chain.
