Hi,
please find attached a backport to 1.13 of the given patch set including
fixes from Lukas.
It's intention is to fix
https://fedorahosted.org/sssd/ticket/3118 /
https://bugzilla.redhat.com/show_bug.cgi?id=1367802 without introducing
a new patch. As a side-effect the issue with missing overriden names
from group members is fixed as well. But since the patches touches
various parts of the group lookup code it should be carefully tested for
regressions.
