The version of sudo that ships with Debian by default resets the
environment, as described by the "env_reset" flag in the sudoers file.
This implies that all environment variables are removed, except for
LOGNAME, PATH, SHELL, TERM, DISPLAY, XAUTHORITY, XAUTHORIZATION, XAPPLRESDIR,
XFILESEARCHPATH, XUSERFILESEARCHPATH, LANG, LANGUAGE, LC_*, and USER.
In case you want sudo to preserve more environment variables, you must
specify the env_keep variable in the sudoers file. You should edit the
sudoers file using the visudo tool.
Examples:
Preserve the default variables plus the EDITOR variable:
Defaults env_keep+="EDITOR"
Preserve the default variables plus all variables starting with LC_:
Defaults env_keep+="LC_*"

If you're using the sudo-ldap package, note that it is now configured to
look for /etc/sudo-ldap.conf. Depending on your system configuration, it
probably makes sense for this to be a symlink to /etc/ldap.conf, or perhaps
to /etc/libnss-ldap.conf or /etc/pam_ldap.conf. By default, no symlink or
file is provided, you'll need to decide what to do and create a suitable
file before sudo-ldap will work.

As of version 1.7, sudo-ldap now requires the LDAP source to be specified
in /etc/nsswitch.conf with a line like:
sudoers: ldap

Note that the support for the sss provider (libsss_sudo.so) that allows sudo
to use SSSD as a cache for policies stored in LDAP is included in the sudo
package, not in the sudo-ldap package. I have some hope that this turns out
to be a better overall solution for using sudo with LDAP, as the sudo-ldap
package is difficult to maintain and I'd love to be able to eliminate it!

build options used in building the Debian package.

If you're having trouble grasping the fundamental idea of what sudo is all
about, here's a succinct and humorous take on it...
