You can maintain up to two login data definitions for each vnode. If the first definition has been defined as private, the other login must be global (and vice versa). A global entry is available to all users on the local instance. A private entry is available only to the user who creates it.

If one of the login data definitions is private and the other is global, the vnode is considered to be an advanced vnode. A vnode is also considered to be an advanced vnode if it has more than one connection data definition and/or has one or more vnode attribute definitions.
