...

• Login to the machine with the ece-li-admin account.

  Code Block
  sudo adduser username<username> --disabled-password --gecos ""

• Enter any relevant information for the user account.

  Code Block
  sudo usermod -aG sudo username<username>

• To test the new account, logout and log back in using the new user account.

...

• Run visudo.

  Code Block
  sudo visudo

• Find the sudo group entry. It will look like the following:

  Code Block

• Add a no-password rule:
