When forcing AD users to enter a password using sudo, authentication fails
An entry was added to the /etc/sudoers file to force the AD user to enter their password, however after doing so the user is unable to authenticate.
This problem can be caused by the presence of the "rootpw" or "targetpw" option in the sudoers file. These option are off by default, but when set they will require the user to enter a password other than their own password when running sudo. This has caused confusion in the past for users who were unaware the option was set.
Inform users they must be entering the root or other users password to run commands from sudo, or remove the "rootpw" or "targetpw" options if that behavior is not desired.
