Recognition works but don't get authenticated. #52

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Built and installed according to instructions
2. Trained it using provider qt-facetrainer application, verified that 
recognition worked
3. Altered my /etc/pam.d/su and sudo (added the statement 'auth sufficent 
pam_face_authentication.so enableX' to them).

What is the expected output? What do you see instead?
When I try to sudo the following happens:
kristoffer@bastet:~$ sudo vim /etc/pam.d/su
Face Verification Pluggable Authentication Module Started
Verifying Face ... [Verification screen pops up and does its thing]
Verification successful.
[sudo] password for kristoffer: [I wonder why I need to do this, but I enter 
the correct password here]
Sorry, try again.
Face Verification Pluggable Authentication Module Started
Floating point exception
[prompt comes back]

What version of the product are you using? On what operating system?
0.3 on Ubuntu 10.04

Please provide any additional information below.

The behaviour is correct that the plugin is executed again when the password 
login has failed.

The problem indeed is that you are asked for a password although the login has 
succeded. I would recommend you one other try-out:
Have a look at 
http://pam-face-authentication.org/wiki/index.php?title=Installation#.28K.29Ubun
tu
and scroll down where it says "Option B". Priorly to this you have to remove 
the entries in /etc/pam.d/su and /etc/pam.d/sudo of course...

Thanks for your reply. However, I am 100% sure that I entered the correct 
password, also, the floating point error is what bothers me.

I rebooted off a rescue CD and removed face auth from the pam.d-files. The wiki 
link with instructions looks very much like the instructions I followed when 
building and installing pam-face-authentication.

I want to update my state here.

After compiling both OpenCV-2.3.1 and pam-face-authenticate with GCC 4.7.1, it 
works now for sudo.

But somehow kdm plugin doesn't work as still, I am trying to make it dump some 
message to trace.
