This parameter is required. Empty strings and NULL strings are universally rejected.
The parameter has no default value, and must be explicitly set.
The user name does not have to be unique when a remote ID is used. See Remote IDs.
This MobiLink user name and password are separate from any database user ID and password, and serves only to identify and
authenticate the application to the MobiLink server. See Password synchronization parameter.
For a user to be part of a synchronization system, you must register the user name with the MobiLink server. The user name
is stored in the name column of the ml_user MobiLink system table in the consolidated database.
