Comment 5 for bug 479881

Hi there,

You could use substack option of pam. The solution is mentioned here http://live.gnome.org/GnomeKeyring/Pam

So your gdm config file should like

>> cat /etc/pam.d/gdm:
#%PAM-1.0
auth requisite pam_nologin.so
auth required pam_env.so readenv=1
auth required pam_env.so readenv=1 envfile=/etc/default/locale
auth sufficient pam_succeed_if.so user ingroup nopasswdlogin

auth substack common-auth

auth optional pam_gnome_keyring.so
@include common-account
session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so close
session required pam_limits.so
@include common-session
session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so open
session optional pam_gnome_keyring.so auto_start
@include common-password

Finally, add
auth sufficient pam_face_authentication.so enableX to the top of /etc/pam.d/common-auth - I hope this fixes things.
