In global clusters, VCS provides the option of making the following types of communication secure:
Communication between the wide-area connectors.
Communication between the wide-area connectors and the Steward process.
For secure authentication, the wide-area connector process gets a security context as an account in the local authentication broker on each cluster node.
The WAC account belongs to the same domain as HAD and Command Server and is specified as:
name = WAC domain = VCS_SERVICES@cluster_uuid
You must configure the wide-area connector process in all clusters to run in secure mode. If the wide-area connector process runs in secure mode, you must run the Steward in secure mode.
