Installation Fails if Default Domain is not set (4913925)

Problem Summary: When adding nodes to a cluster during installation and configuration, you may see an “RPC authentication“ failure. The error messages are similar to the following:

• “RPC authentication error”

• “Not authorized to communicate with <sponsor-node>”

• “Cluster name verification failed”

This will occur when the nodes are not configured to use NIS/NIS+, particularly if the file /etc/defaultdomain is not present.

Workaround: When a domain name is not set (that is, the /etc/defaultdomain file is missing), set the domain name on all nodes joining the cluster, using the domainname(1M) command before proceeding with the installation. For example, # domainname xxx.
