"Problem with defaults entries" emails being sent to admin email

Symptoms

When a user uses the sudo command, an email similar to the following is sent to the admin email.

sudo: wp-toolkit : problem with defaults entries ; TTY=unknown ; PWD=/usr/local/cpanel/3rdparty/wp-toolkit/scripts ; USER=root ;

Description 

When the System Security Services Daemon is installed, it adds an sss entry to the /etc/nsswitch.conf file. This causes SSSD to run using sudo, which will send the email when a local user runs sudo because SSSD doesn't support sudo rules for local users.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Open /etc/nsswitch.conf in your preferred text editor.
3. Find the sudoers line.

   sudoers: files sss

4. Remove the sss entry from the line.

   sudoers: files

5. Save the changes and exit the text editor.
