You can add, modify, and delete users on any system in the cluster, provided you have the privileges to do so.
If VCS is running in secure mode, specify fully-qualified user names, in the format username@domain. You cannot assign or change passwords for users when VCS is running in secure mode.
The commands to add, modify, and delete a user must be executed only as root or administrator and only if the VCS configuration is in read/write mode.
