effectively (not directly) add "required pam_tally2.so debug" to /etc/pam.d/common-account 
This is required because otherwise something like "sudo bash" would count as a
failed login for pam_tally2 even though it was successful.

set back to default group "root" rather than group "sudo" membership required to use su 
since root login will be locked by default anyhow
