Certificates with that OID (as SAN) indicates that the node with this certificate is a “real” cluster node, not only a node-client or transport-client.
So other nodes can know if this node is allowed to request shard replication for example.
Currently is has to be 22.214.171.124.5.5 and is has to be the same for every node in the cluster.

I was wondering what is the function of the OIDs in the SAN field for certificates, could you perhaps briefly explain?
`Does it always have to be 126.96.36.199.5.5? Does it have to be the same for every node in the cluster?
