In secure mode, VCS assigns guest privileges to all native users.
When you assign privileges for clusters running in secure mode, you must specify fully-qualified user names, in the format username@domain.
When you assign privileges for clusters running in secure mode, you must specify user names in one of the following formats:
To add a cluster-level user, specify only the user name.
To add a node-level user, specify the user name in the username@FQDN format, where FQDN is the fully qualified domain name.
In a secure cluster, if the external communication port for VCS is not open, only root users logged on to the host system can run CLI commands.
See Cluster attributes.
You cannot assign or change passwords for users that use VCS when VCS runs in secure mode.
