Credential provider client for Vista/Windows server 2008

I need a working code (well documented w/ source) to replace/modify windows

logon with credential provider extensions.

C#/.net is preferred, but c++ is also ok.

1. First screen should be user-id input and possibly domain input (both are text fields) with a button.

[notice there is no password in this screen]

2. Then the thin client (whatever dll you come up with) will fetch two images from remote server based on the user-id.

https would be a preferred method (w/ get/post). Other methods (protocols are ok, if we can get this done as quickly as possible) and one string (ascii/utf character)

3. The user is presented with the two images and one input text field (password) with a click ok button

4. once user inputs the password, it is compared with the text obtained from the server while fetching images in step 2.

If they match, user logs in; else 2 more attempts repeated from step2 before locking down (optional).

For testing purposes, you can have your own images and text stored on files (instead of our server)

C# is preferred, but c++ is also ok.

Microsoft SDK already has cpp files to start with

Need atleast one verifiable reference, if selected; To be completed at the earliest.

You will be asked to transfer copyrights to the code,

or atleast certificate that we can use it without liabilities

sample cpp vc++ attached (from ms sdk).

This mini-project would lead to a bigger one if executed properly. Thx
