Finger scan for authentication does not work in Jaunty

[Raja]

New install of Ubuntu Jaunty (alpha 5) amd-64 version on Thinkpad X61s.

Installed thinkfinger from repositories, added fingerprint using tf-tool and set up pam using pam-thinkfinger-enable script.
Now prompt changed to 'password or swipe finger' on gdm and in terminal, but nothing happens on swiping. I thought this might be same as previously reported Bug #256429. But carriage returns in no output (not authenticated, but no error message). Here is a sample session - please note that tf-tool verifies the fingerprint correctly.

Initializing... done.
Please swipe your finger (successful swipes 1/1, failed swipes: 0)... done.
Result: Fingerprint does match.

I am attaching my /etc/pam.d/common-auth. Will be happy to provide any more information as required.

I had the same results. I installed the intrepid version from here.
deb http://ppa.launchpad.net/jon-oberheide/ubuntu intrepid main

and it appears to work now. I am using a X61 tablet with 0483:2016 SGS Thomson Microelectronics Fingerprint Reader
The only difference is that the initialize on the usb scanner is a lot longer than on intrepid--This may be hal. The time you type sudo till you get the "password or swipe finger" is around 5 seconds. Same thing on intrepid was just about instant.

This fix only partially worked for me. The huge delay is still there.

The #311732 patch fixes the delay as well. This appears to be a duplicate of that problem.
