This configuration parameter specifies the full path to a file containing the warning message you want displayed. If this parameter is not set, a default message is displayed.

For example, to use a custom message in the file dzdo_warning:

dzdo.lecture_file: /etc/custom/dzdo_warning

This configuration parameter provides functionality equivalent to the lecture_file flag for configuring the sudoers file and sudo operation.

You can also set this parameter using group policy.
