As a system administrator, I want the communication between nodes
to be secure. I also want to configure secure communication using
a convenient process which scales to large clusters.
New nodes (or merging partitions) should authenticate themselves before they are allowed to join the cluster.
The objective is to enable secure communication within node of a
cluster in a convenient manner, preferable at the Cluster level (not just
node level). This will enable easy configuration for large clusters.

Verified joining node authentication with DIGEST-MD5 and GSSAPI mechanisms.
