I've just solved this bug. To solve it, someone has to login in with root account with 'sudo bash' in a terminal emulator, and open /etc/pam.d/common-session-noninteractive with 'gedit /etc/pam.d/common- session-noninteractive', and he or she has to look for the line n°16 and he or she has to change [default=1] in [default=0]. Try 'sudo id' or another command with 'sudo' and there is no bug!
