Safeguard 8.0 SmartCard Login



I installed an Sophos Safeguard 8.0 Server with my policies. I created a testuser and enabled smartcard login for that User. With that i set the logon mode for the Safeguard authentication also to "Token". 

Middleware etc. is also installed on the client machine.

So if i logon to the machine (Here i have to choose the Windows Credential Provider with SmartCard Logon, and not the Safeguard Credential Provider because with that i am not able to Login , there is no option for smartcard login) with the smart card the safegaurd login pop up appears and asks for username and password. If i enter the password for the user the message Smartcard login required but not used appears.

Does anyone know what to do that smartcard logon works for windows and safeguard?
