NIFI-5752: Load balancing fails with wildcard certs

> Key: NIFI-5752

> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.8.0
> Reporter: Kotaro Terada
> Priority: Major
>
> Load balancing fails when we construct a secure cluster with wildcard certs.
> For example, assume that we have a valid wildcard cert for {{*.example.com}}
> and a cluster consists of {{nf1.example.com}}, {{nf2.example.com}}, and
> {{nf3.example.com}} . We cannot transfer a FlowFile between nodes for load
> balancing because of the following authorization error:
> {noformat}
> 2018-10-25 19:05:13,520 WARN [Load Balance Server Thread-2]
> o.a.n.c.q.c.s.ClusterLoadBalanceAuthorizer Authorization failed for Client
