GN4 name users are configured in EdAdmin4 or in the Administrative Browser.
GN4 users and domain users
GN4 users are, by definition, a subset of domain users. Since GN4 is based on "named users", you are not supposed to import all the domain users in the GN4 database, but only those users who will effectively use GN4.
At the present time, there's no provision to import selected domain users in the GN4 database.
About reserved names
Default users Guest and Administrator must always exist.
They should not be renamed.
Also, never rename anything in the s_objecttable, as doing so you will break the MD5Key, making the object “invalid”.
