Replacing dll driver and its integrity

Question

I developed testing dll driver for Windows Biometric Framework. This driver takes care of storing fingerprint information.

WinBio uses 3 types of driver - engine,storage and sensor. These were installed with biometric sensor.

I'd like to replace storage adapter with my own. So I simply copyied my implementation to corresponding folder and changed value in registry to use my dll. But when I test my application I get error at Opening Session that says

The adapter binary did not pass its integrity check

What exactly do I need to make it work with my application?

Thanks in advance

You will need to sign your plug-in driver - for testing you can use a test certificate you create using WDK tools. Details can be found in the Windows Biometric Framework: Code-Signing Guidelines.
