Details

If i "sudo any command" it takes as reported annoying 5secs until i cannot enter any password.

If the "Password or swipe finger:" appears and i quickly enter the right password it takes again about 5secs to work and then "Password: " is showed up again. At this time i cannot use the fingerprint reader to authenticate but the entered password would not be rejected and everything goes quick.

If someone wants to say that this 5secs are needed: its not true.
I also use this thinkfinger reader on other "non linux" systems and it works well without any noticed waiting time
This task depends upon

I am having something similar happening. When I use yaourt (and this is the only time it happens), I have to type in root password four times before it's accepted when it gets to the "install the package" point, whereas prior to earlier this month, I didn't have to.

Referring thread: http://bjoernvold.com/forum/viewtopic.php?p=5154#p5154

This is not to do with a thinkfinger; however, it denotes a password issue in general.

Thanks.

Has this been reported to the thinkfinger developer?

Here's the solution:
http://www.joaoff.com/2009/06/30/making-thinkfinger-faster/
I couldn't build the entire package, the pam part is broken (something about compiler flags).
I just replaced libthinkfinger whith the patched one and everything is ok, much faster.
I'd like to see this patch integrated in the package..
