alternate Data Source Parameters
A set of alternate data source parameters that you want to share for the credentials
stored with this data source. The credentials are applied in tandem with the data source
parameters when you copy a data source by using a create or update request. The API
operation compares the DataSourceParameters structure that's in the request
with the structures in the AlternateDataSourceParameters allow list. If the
structures are an exact match, the request is allowed to use the credentials from this
existing data source. If the AlternateDataSourceParameters list is null,
the Credentials originally used with this DataSourceParameters
are automatically allowed.
