sudo - prompting for password

When using sudo to root, it is asking for password. The reason was it was reading the config file /etc/sudoers.d/svc-system-config-user before reading /etc/sudoers. Emptied the config file and issue was resolved.

# cat /etc/sudoers.d/svc-system-config-user

sam@sopc-sp-v01:~$ sudo su -
