This explicitly avoids the legacy_[ug]id_to_sid calls, which create long-term cache entries to S-1-22-x-y if anthing fails. We can't do this, because this will turn temporary winbind communication failures into long-term problems: A short hickup in winbind_uid_to_sid will create a mapping to S-1-22-1-uid for a week. It should be up to the lower layers to do the caching. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Christof Schmitt <cs@samba.org> Bug: https://bugzilla.samba.org/show_bug.cgi?id=13813
