> Key: NIFI-2550
> URL: https://issues.apache.org/jira/browse/NIFI-2550
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.0.0
> Environment: Site-to-Site, Secure Cluster to Secure Cluster
> Reporter: Koji Kawamura

> I'm trying to setup a Site-to-Site connection between two NiFi clusters (P
> and Q). Both secured.
> At NiFi Q, there's an input-port, then NiFi P sends data to it.
> NiFi P -> https -> NiFi Q
> NiFi P has two nodes, so I created a group 'p-nifi' having the nodes identity
> on NiFi Q. Then add 'p-nifi' group to 'retrieve site-to-site detail' policy.
> Confirmed that NiFi P Remote Process Group can get site-to-site detail.
> However, it couldn't access input-port.
> I've added 'p-nifi' group to 'receive data via site-to-site' policy of the
> input-port, but still it can't accessed.
> I found that
> org.apache.nifi.authorization.resource.DataAuthorizable.checkAuthorization
> checks all the DN chain. By debugging, I found that it checks not only NiFi P
> nodes, but also NiFi Q nodes. The DN chain looked like below:
> [L=1.p.nifi, C=US, CN=1.p.nifi, L=0.q.nifi, C=US, CN=0.q.nifi, L=1.q.nifi,
> C=US, CN=1.q.nifi]
> After adding 'q-nifi' group to the input port policy, NiFi P can access the
> remote input port.
> There maybe some reason for doing this, but as an user, I didn't expect that
> I need to add NiFi Q to that policy.
> Is this an expected behavior?
