Edit: /usr/share/doc/sudo/OPTIONS (1482B)
The following options were used to configure sudo for Debian GNU/Linux.
--with-all-insults
Include all the insults in the binary, won't be enabled unless turned
on in the sudoers file.
--with-devel
Force flex and bison runs on each build.
--with-pam
Support for pluggable authentication modules.
--with-fqdn
Allow use of fully qualified domain names in the sudoers file.
--with-logging=syslog
--with-logfac=authpriv
Where logging information goes.
--with-env-editor
--with-editor=/usr/bin/editor
Honor the EDITOR and VISUAL environment variables. If they are not
present, default to the preferred systemwide default editor.
--with-timeout=15
--with-password-timeout=0
--with-passprompt="[sudo] password for %p: "
Allow 15 minutes before a user has to re-type their passord, versus
the sudo usual default of 5. Never time out while waiting for a
password to be typed, this is important to Debian package developers
using 'dpkg-buildpackage -rsudo'. Make it clear which password is
requested.
--disable-root-mailer
Send mail as the invoking user, not as root.
--with-sendmail=/usr/sbin/sendmail
Use Debian policy to know the location of sendmail instead of trying
to detect it at build time.
--with-timedir=/var/lib/sudo
--mandir=/usr/share/man
--libexecdir=/usr/lib
Comply with Debian policy on suitable paths.
--with-ldap
Support for LDAP authentication, in the sudo-ldap package version only.
