* d/patches/lp_970679_fix-large-groups.patch: Cherry picked patch from upstream VCS to resolve issue with winbind crashing with groups containing more than 1000 members (LP: #970679). * d/control: Fixup Breaks/Replaces on libnss-winbind so that upgrades from libpam-winbind don't break. Thanks to Colin Watson for identifying this issue.
