Yeh - the MAAS user needs a bunch of SUDO access.  

I have these
root@region:/etc/sudoers.d# pwd
/etc/sudoers.d
root@region:/etc/sudoers.d# ls -1 | grep maas
10_maas_rack
10_maas_restart_bind9
10_maas_restart_maas-dhcpd
10_maas_restart_maas-dhcpd6
10_maas_restart_maas_proxy
10_maas_restart_ntp
10_maas_restart_tgt
10_maas_start_bind9
10_maas_start_maas-dhcpd
10_maas_start_maas-dhcpd6
10_maas_start_maas_proxy
10_maas_start_ntp
10_maas_start_tgt
10_maas_status_bind9
10_maas_status_maas-dhcpd
10_maas_status_maas-dhcpd6
10_maas_status_maas_proxy
10_maas_status_ntp
10_maas_status_tgt
10_maas_stop_bind9
10_maas_stop_maas-dhcpd
10_maas_stop_maas-dhcpd6
10_maas_stop_maas_proxy
10_maas_stop_ntp
10_maas_stop_tgt
root@region:/etc/sudoers.d#

and each one looks a bit like this
root@region:/etc/sudoers.d# cat 10_maas_restart_bind9
maas ALL= NOPASSWD: /bin/systemctl restart bind9

Regards
Pete
