I'd actually like to make it a teensy bit more general and think about the non-Thinkfinger readers also. From my Pile Of Laptops, the Authentec readers are pretty common. And davidz has already done some prodding with them based on his blog ;) While not very relevant to the interaction, it's mostly important so that we don't make assumptions of hardware capabilities that may or may not be present. > Can it's presence be detected automatically?

Adding the pam config is just a matter of deciding we're doing it and then adding to the stacks written out by authconfig > How many times does it take to train think finger support initially? This probably depends on the hardware. Thinkfinger is 3 swipes and trained in hardware. Some of the other readers just give you back an image and you have to do verification[1] on your own. But probably 3 is a reasonable guess there too. It's at least the range of "more than one, less than many" > Can it be (re)trained incrementally? Is this required? Nope, you pretty much have to do the initial readings upfront. > Can we get the image from think finger for user feedback? Ray mentioned > we might be able to fake it, which would probably be good enough. This is definitely going to be dependent on the hardware, so probably can't be counted on. > Can we detect / remember the number of failed think finger attempts > before a successful one? This is related to retraining, if it's > possible to retrain the reader or human to scan better over time. PAM doesn't usually keep track of a number of failures. You could have a module do it, though if you really wanted I think.
