With the new ipa_server_mode SSSD is able to read user and group data
from trusted AD domains directly and makes this data available via the
NSS responder. With this mode enabled winbind is not needed anymore to
lookup users and groups of trusted domains.
This patch removed the calls to winbind from the extdom plugin and
replaces them with standard POSIX calls like getpwnam() and calls from
libsss_nss_idmap to lookup SIDs.
Fixes https://fedorahosted.org/freeipa/ticket/3637 because now the
extdom plugin does not need to handle idranges anymore, but everything
is done inside SSSD.
This extop can be used by clients of the IPA domain, e.g. sssd, to
retrieve data from trusted external domains. It can be used e.g. to map
Windows SIDs to user or groups names and back.
