Additional info:
The problem is with the pam file (/etc/pam.d/smart).
changing it to

account         include         config-util
session         include         config-util

instead of
auth       sufficient   /lib/security/pam_rootok.so
auth       sufficient   /lib/security/pam_timestamp.so
auth       required     /lib/security/pam_stack.so service=system-auth
session    required     /lib/security/pam_permit.so
session    optional     /lib/security/pam_xauth.so
