#
# Default /etc/sudo.conf file
#
# Sudo plugins:
#   Plugin plugin_name plugin_path plugin_options ...
#
# The plugin_path is relative to /usr/lib/sudo unless
#   fully qualified.
# The plugin_name corresponds to a global symbol in the plugin
#   that contains the plugin interface structure.
# The plugin_options are optional.
#
# The sudoers plugin is used by default if no Plugin lines are present.
#Plugin sudoers_policy sudoers.so
#Plugin sudoers_io sudoers.so
#Plugin sudoers_audit sudoers.so

#
# Sudo askpass:
#   Path askpass /path/to/askpass
#
# An askpass helper program may be specified to provide a graphical
# password prompt for "sudo -A" support.  Sudo does not ship with its
# own askpass program but can use the OpenSSH askpass.
#
# Use the OpenSSH askpass
#Path askpass /usr/X11R6/bin/ssh-askpass
#
# Use the Gnome OpenSSH askpass
#Path askpass /usr/libexec/openssh/gnome-ssh-askpass

#
# Sudo device search path:
#   Path devsearch /dev/path1:/dev/path2:/dev
#
# A colon-separated list of paths to check when searching for a user's
# terminal device.
#
#Path devsearch /dev/pts:/dev/vt:/dev/term:/dev/zcons:/dev/pty:/dev

#
# Sudo command interception:
#   Path intercept /path/to/sudo_intercept.so
#
# Path to a shared library containing replacements for the execv(),
# execve() and fexecve() library functions, which perform a policy
# check to verify whether the command is allowed and simply return
# an error if it is not.  This is used to implement the "intercept"
# functionality on systems that support LD_PRELOAD or its equivalent.
#
# The compiled-in value is usually sufficient and should only be changed
# if you rename or move the sudo_intercept.so file.
#
#Path intercept /usr/lib/sudo/sudo_intercept.so

#
# Sudo noexec:
#   Path noexec /path/to/sudo_noexec.so
#
# Path to a shared library containing replacements for the execv(),
# execve() and fexecve() library functions that just return an error.
# This is used to implement the "noexec" functionality on systems that
# support LD_PRELOAD or its equivalent.
#
# The compiled-in value is usually sufficient and should only be changed
# if you rename or move the sudo_noexec.so file.
#
#Path noexec /usr/lib/sudo/sudo_noexec.so

#
# Sudo plugin directory:
#   Path plugin_dir /path/to/plugins
#
# The default directory to use when searching for plugins that are
# specified without a fully-qualified path name.
#
#Path plugin_dir /usr/lib/sudo

#
# Core dumps:
#   Set disable_coredump true|false
#
# By default, sudo disables core dumps while it is executing (they
# are re-enabled for the command that is run).
# To aid in debugging sudo problems, you may wish to enable core
# dumps by setting "disable_coredump" to false.
#
#Set disable_coredump false

#
# User groups:
#   Set group_source static|dynamic|adaptive
#
# Sudo passes the user's group list to the policy plugin.
# If the user is a member of the maximum number of groups (usually 16),
# sudo will query the group database directly to be sure to include
# the full list of groups.
#
# On some systems, this can be expensive so the behavior is configurable.
# The "group_source" setting has three possible values:
#   static   - use the user's list of groups returned by the kernel.
#   dynamic  - query the group database to find the list of groups.
#   adaptive - if user is in less than the maximum number of groups.
#	       use the kernel list, else query the group database.
#
#Set group_source static

#
# Sudo interface probing:
#   Set probe_interfaces true|false
#
# By default, sudo will probe the system's network interfaces and
# pass the IP address of each enabled interface to the policy plugin.
# On systems with a large number of virtual interfaces this may take
# a noticeable amount of time.
#
#Set probe_interfaces false

#
# Sudo debug files:
#   Debug program /path/to/debug_log subsystem@priority[,subsyste@priority]
#
# Sudo and related programs support logging debug information to a file.
# The program is typically sudo, sudoers.so, sudoreplay, or visudo.
#
# Subsystems vary based on the program; "all" matches all subsystems.
# Priority may be crit, err, warn, notice, diag, info, trace, or debug.
# Multiple subsystem@priority may be specified, separated by a comma.
#
#Debug sudo /var/log/sudo_debug all@debug
#Debug sudoers.so /var/log/sudoers_debug all@debug
