The caller identifies himself by issuing
Connection.setCredentials(). The corresponding
User object is retrieved from the registry using the
name given in the credentials. If the user record does not yet exist, it is
created. This new user object is not added to any organization.
Here, the user name is the name attribute as inherited from the
RegistryObject interface. It should not be confused with
the user's PersonName.
The caller must be known before a connection can be used. In other
words, setCredentials() is required, otherwise a
security error occurs.
Note:
The user name must be unique in the registry.
