No 'Password or swipe finger' prompt after setting up ThinkFinger

[Thomas Kane]

I don't get neither 'Password or swipe finger' nor whatever gnome's graphical swipe your finger prompt is after setting up ThinkFinger. tf-tool --acquire and tf-tool --verify both return no problems.

Here's the relevant excerpt from my /etc/pam.d/common-auth:
# here are the per-package modules (the "Primary" block)
auth [success=2 default=ignore] pam_thinkfinger.so
auth [success=1 default=ignore] pam_unix.so nullok_secure try_first_pass

From http://www.thinkwiki.org/wiki/How_to_enable_the_fingerprint_reader_with_ThinkFinger :
"You should see the "Password or swipe finger:" prompt when trying to sudo or su. If you don't, you probably do not have the "User level driver support" compiled into your kernel or the "uinput" module loaded!"

For some reason driver isn't loading:
sudo modprobe uinput
lsmod | grep uinput

Is it compiled in?

Hello Thomas, does thinkfinger work for you on login and/or in the Ubuntu Software Center?

[Thomas Kane (tkane)]

Does work in software center; don't know about on login as I'm auto loging in. Doesn't in terminal window.

Alright, then this seems to be the same bug as mine. Marking as duplicate.

I found out, it is actually a bug in sudo. See bug #609645 for a fix.
