Plugins
Plugins may be specified via Plugin directives in the
sudo.conf(5) file. They may be loaded as dynamic shared
objects (on systems that support them), or compiled directly
into the sudo binary. If no sudo.conf(5) file is present,
or it contains no Plugin lines, sudo will use the tradi‐
tional sudoers security policy and I/O logging. See the
sudo.conf(5) manual for details of the /etc/sudo.conf file
and the sudo_plugin(8) manual for more information about the
sudo plugin architecture.
