Ginastub download

RE: ginastub. Posted Apr 10, AM. Posted Apr 11, PM. While not the 'prettiest' finish, the registry key capture does actually complete which is good and as long as I hit Restart and don't simply turn off the clients when done, the machine works when restarted If I turn off the machine at that dialog, I am in trouble as it does not reset the logon to point at msgina instead of ginastub.

Here's the data you asked for:. No step failed in the log 3. There is a Restart button as well. No odd logon procedures. XP Pro SP2. Posted Apr 12, AM.

I would like to get to the bottom of this. Let's start by seeing if the data in the gina entry is consistent with what is being reported by the error dialog. Some other application or service may be attempting to chain our gina, and causing the load to fail.

If that turns out to be the case we would need to know what that application or service is. Digital signatures [? DLL has a valid digital signature. Hashes [? DLL: I will keep it I will remove it.

I have opened the MSDN website but could not download all samples because of my broken connection I want to know what is GINA.. If we want to extend functionality of GINA then how can we do that!!

I think the sample does the same.. I want to step up in Windows NT services now.. Thank you!! I need to modify this. If you really want to mess around with this, I can send you the code from the link below. Its not a service though. But if you're pulling in MFC or even something more sophisticated, you might ask yourself if GINA is the right place for such application frameworks. Remember that a good GINA is small, simple, and bulletproof. Try to keep the amount of code your GINA loads to an absolute minimum.

It's designed to be single threaded, at least as far as WinLogon is concerned. WinLogon doesn't expect to be called back on any thread other than the one it used to call into GINA in the first place. It should instead use WinLogon's thread to make the call. If you do have a secondary thread that receives the device notification, you can simply post a message to your dialog that's displaying the SAS or Locked notice.

Once your GINA is built, you'll want to deploy it and test it out. I strongly recommend that you don't deploy the GINA to your development box. Use a separate machine to host your GINA for testing. My own setup relies on Virtual PC with its undo disk feature.

If something goes really wrong and I end up in an infinite reboot loop yes, this will happen to you at some point , I just close down the Virtual PC and discard changes. To deploy the GINA for testing, just copy the DLL onto the target machine it is appropriate to place it in the System32 directory , and update that machine's registry by adding a named value under WinLogon's key:.

Reboot the machine, and you'll find your GINA running when the machine boots back up. If you are trying to redeploy a new version of your GINA, you may find that the existing version is locked by the operating system and that you cannot overwrite the file. In this case, rename the GINA file on disk before copying the new one. Then you can simply delete the old GINA later. If you get into trouble and need to restore the old GINA, just delete the GinaDLL key and remember that you can access the registry of any machine remotely, as long as you can be authenticated as an administrator on the target machine.

You won't get this level of protection by default simply by installing into the System32 directory. Unless you're someone who regularly uses low-level symbolic debuggers, you won't enjoy debugging a custom GINA while it's running inside WinLogon.

That's why I designed my sample so that it can be run outside of WinLogon, and I recommend you design yours the same way. In non-debug builds, this function does absolutely nothing. The key to making this possible is to abstract your interface to WinLogon so that when debugging, you can simulate the WinLogon dispatch table by providing your own implementation.

The standard way of doing this in unit testing circles is to use interfaces coupled with mock objects. Then during normal operation, I use an implementation of IWinLogon that actually calls through WinLogon's dispatch table. During debugging, I substitute a mock implementation that in many cases can get away with doing absolutely nothing. It's dirt simple, and it works like a charm. Of course, you'll need a program to load your GINA and call that debug entry point, but that's easy.
