The 'sudo' command allows authorized users to run programs (including shells) as other users, system users, and root. The '/etc/sudoers' file is used to configure authorized 'sudo' users as well as the programs they are allowed to run. Some configuration options in the '/etc/sudoers' file allow configured users to run programs without re-authenticating. Use of these configuration options makes it easier for one compromised account to be used to compromise other accounts.

It is possible to include other sudoers files from within the sudoers file currently being parsed using the #include and #includedir directives. When sudo reaches this line it will suspend processing of the current file (/etc/sudoers) and switch to the specified file/directory. Once the end of the included file(s) is reached, the rest of /etc/sudoers will be processed. Files that are included may themselves include other files. A hard limit of 128 nested include files is enforced to prevent include file loops.


Configure the /etc/sudoers file to only include the /etc/sudoers.d directory.

Edit the /etc/sudoers file with the following command:

$ sudo visudo

Add or modify the following line:
#includedir /etc/sudoers.d
