After server migrated to AD, group policy configured and setup, we get the following serror when doing a 'sudo su -' command.
sudo su -
ADuser is not in the sudoers file. This incident will be reported.
This happens on QAS 184.108.40.206 with Sudo version 1.6.8p9
Using VGP, I typed the group name instead of using the browse and lookup in ad. This way just the group gets added without the AD info(@example.com). This allows me to manage the policy & group from via AD console rather than touching each server sudo file.
