Package: libpam-fprint
Version: 20080330+git-5
Severity: normal

*** Please type your report below this line ***

libpam-fprint does no longer work with sudo. It did in the past (a month or two ago) but with an sudo update, it stopped working. This was the old experimental version.

In the meantime I have got the new version installed (in testing) and the same problem happens. I no longer have fprint configured in pam manually but automatically with "dpkg-reconfigure libpam-fprint" - this gives the same behaviour. If I disable unix authentication, sudo just skips to say that it cannot find a suitable authentication mechanism.

fprint works perfectly well with su, gdm (versions 2 and 3) and console login, eg.:

mo...@hactar:~$ su - moffe
Scan right index finger on UPEK TouchStrip
mo...@hactar:~$ exit
logout
mo...@hactar:~$ sudo bash
[sudo] password for moffe:
r...@hactar:~#

Notice how sudo goes directly to password authentication while su does only if fingerprint fails.

This is, of course, just annoying (I know my password :-), but sudo is probably the authentication I use the most.

I have no idea what the actual problem is, but I am almost sure this sudo update is the problem:

sudo (1.7.2p6-1) unstable; urgency=low

  * new upstream version fixing CVE-2010-1163, closes: #578275, #570737

Note that I only *assume* this is an fprint problem - feel free to reassign to sudo if you think it is the problem...
