Hello!

FYI, I cc:ed the ThinkFinger mailing list, if anyone who replies want
to do the same he should manually do it.

Package: thinkfinger-tools

The PAM module has its own package, so you should have reported it to
libpam-thinkfinger instead. However, this is not at all a ThinkFinger
bug, but a libgksu one, reassigned.

Version: 0.3~ppa3

Please use a version present in Debian or, at least, explain where it
comes from (Ubuntu package in this case), corrected.

Severity: important

I'm not sure 'important' is the correct severity: while for sure
gksudo (not gksu, read below) hanging is a problem, it's not the worst
possible scenario (again, read below).

The current prompt cause gksudo and gksu to hang waiting on a finger
scan.

gksu-2.0.0-4 never hangs in my case (called as simply as `gksu xterm`
or as `gksu -u luca xterm`), while gksudo yes. And FWIW applying the
~/.thinkfinger.bir patches by Christian Neumair [1] doesn't change
anything. So, this is *not* a ThinkFinger problem.

FWIW, I searched on the net and indeed this bug has already been
reported, in Ubuntu [2][3][4] and upstream [5]. Some solutions have
been proposed, but no one has been accepted, yet.

This is known to upstream and I have no confidence that it will be
addressed any time soon.

Which upstream are you talking about? I'd say that since this is not
a ThinkFinger bug, ThinkFinger upstream will never address it [7].

In the meanwhile, I've got a patch to change the prompt if not
displaying to a tty, often seen on thinkfinger-devel. It works well
on my system. Though it's not obvious that gksudo and friends will
accept a fingerprint, they do.

For what concerns ThinkFinger, I won't apply any patch which doesn't
belong to the upstream project. AFAIK the PAM implementation in
ThinkFinger is standard, so if other programs doesn't work with that
it's not a ThinkFinger problem. For that reason, any hack to have
those programs working with ThinkFinger doesn't belong to ThinkFinger
at all.

Thx, bye,
Gismo / Luca
