Fingerprint Login on Linux Mint 17 (Cinnamon, x64)

Postby Mint Condition on Tue Jun 24, 2014 9:41 am

Dear Linux Mint forum community,

I recently upgraded my Thinkpad X61s to Linux Mint 17 from version 16 which I had before. On Mint 16, fingerprint login worked fine after installing and setting up fingerprint-gui.
However, with Mint 17, I cannot log in with MDM.
Everything else seems to work though: It shows me the message to swype my finger, then it shows "OK" - but MDM displays the message that a false password has been entered.
In cinnamon however, after logging in with my password, sudo and gksu work fine with the fingerprint reader.

Here's an excerpt from /var/log/auth.log, which I think contains the relevant information:
Code: Select all
Jun 24 15:18:18 ThinkPad-X61s pam_fingerprint-gui[2613]: Prompting password returned PAM_SUCCESS.
Jun 24 15:18:18 ThinkPad-X61s fingerprint-helper[2703]: Got SIGUSR2, EXIT_SUCCESS.
Jun 24 15:18:18 ThinkPad-X61s fingerprint-helper[2703]: Devices released.
Jun 24 15:18:18 ThinkPad-X61s pam_fingerprint-gui[2613]: Got password by keyboard.
Jun 24 15:18:18 ThinkPad-X61s pam_fingerprint-gui[2613]: Return 25 (PAM_IGNORE).
Jun 24 15:18:18 ThinkPad-X61s mdm[2613]: pam_unix(mdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost=  user=username
Jun 24 15:18:21 ThinkPad-X61s mdm[2613]: WARNING: Couldn't authenticate user
Jun 24 15:18:21 ThinkPad-X61s mdm[2613]: pam_succeed_if(mdm:auth): requirement "user ingroup nopasswdlogin" not met by user "username"


However, wouldn't adding my username into the group "nopasswdlogin" mean, the user always gets logged in without having to enter either a password or to scan a fingerprint?

Please help me with that!

Thanks & best regards!
