I'm looking for a way to disable the smart card PIN change ability provided with Windows 7's native minidriver. It doesn't allow us to enforce any PIN complexity requirements such that users could change their PIN to 000000 or blank without any issues so we'd like to disable that ability. I've been googling around and haven't found any way to do this, but perhaps someone has encountered a similar issue and found a resolution? A third party minidriver is the next step, but if we could do it without additional tools I'm all for it.
