I have configure a Windows Acvite Directory Group Policy which regulates the Behaviour after remove Smartcard from the Client. Without Novellclient it functions everything!
With installed Novellclient (configured in passive Mode) there is no reaction after remove Smartcard!!!

Which is the problem?

Some Info about the client:
Client : Windows XP SP3
Novellclient: Version 4.91 SP4 / SP5 (I have test both)
