b6beccf19e SSSD doesn't handle netgroups, we have to ensure they are correctly filtered 
in sudo. The rules may contain mixed sudoUser specification so we have to
check not only for netgroup membership but also for user and group matches.
Adapted from a patch from Daniel Kopecek.

461a419d04 For sudo -ll (long list) print the SSSD role just like we do 
for the LDAP backend.  Adapted from sudo-1.8.6p3-sssdrulenames.patch

9d526c1af5 Do not write directly to stdout/stderr, use sudo_printf which calls 
the conversation function.

6717c32022 When determining whether or not "sudo -l" or "sudo -b" should prompt 
for a password, take all sudoers sources into account.  In other
words, if both file and ldap sudoers sources are in use, "sudo -v"
will now require that all entries in both sources be have NOPASSWD
(file) or !authenticate (ldap) in the entries.

95dd64ea75 Fix the check for whether a user is allowed to lists another user's 
privileges.  The "matched" variable is not boolean, it can also
have the value UNSPEC so we need to check explicitly for true.
Bug #738

e48ceebf14 fn_free_result() (aka sss_sudo_free_result() in sss_sudo.c) handles 
a NULL poiner so there's no need to check before calling it.  Add
missing initialization of sss_sudo_result to NULL in sudo_sss_setdefs().

60ea106cc4 Add missing return when user is not found in sudo_sss_result_get(). 
Previously we fell through to the default case which just logged a
debug message and returned so this just avoids the extra (generic)
debug message.

0f991ff78b Use user_runhost and user_srunhost instead of user_host and user_shost.

d46d0fbc6f When parsing sudoOptions that include an operator (!, +, +=, -=) 
strip out any whitespace on either side of the operator.

9c9b487b0c In list mode, we always want to clear FLAG_NO_USER and FLAG_NO_HOST 
regardless of whether or not there was an actual match.  Otherwise,
warning mail may be sent which is not what we want in list mode.
This is consistent with what the sudoers file backend does.

374146f70f Avoid calling dlerror() multiple times since it clear the error 
status after printing the error.
Problem caused by sudo_warn/sudo_fatal being macros...

0b241088b3 There's no need to conditionalize the #include <unistd.h>, we require

54f9de6cce Add an error flag to the lbuf struct to simplify error checking.

a memory allocation error ocurred.

866cfc4fc3 Add support for multiple Debug lines per program. Callers may 
register arbitrary debug facilities or use built-in defaults.  We
now use separate Debug statements for plugins and programs.

a7e724b75d Change how sudo.conf is parsed. We now do a quick parse and then 
set the values after the entire file has been parsed.  This lets
us init the debug system earlier.  Plugin-specific debug flags are
now stored in struct plugin_info and struct plugin_container and
passed to the plugin via one or more debug_flags settings.

12f3bdf60e Add wrapper functions for dlopen() et al so that we can support 
statically compiling in the sudoers plugin but still allow other
plugins to be loaded.  The new --enable-static-sudoers configure
option will cause the sudoers plugin to be compiled statically into
the sudo binary.  This does not prevent other plugins from being
loaded as per sudo.conf.

96eb2c4f8f Add warning_gettext() wrapper function that changes to the user locale,

923edabe6c Convert sudo to use BSD TAILQ macros instead of home ground tail 
queue functions.  This includes a private queue.h header derived
from FreeBSD.  It is simpler to just use our own header rather than
try to deal with macros that may or may not be present in various
queue.h incarnations.
