Linked server queries that use MSDASQL fail with error 7416
Linked server queries that use the MSDASQL (OLE DB Provider for ODBC Drivers) provider and specify a provider string ( @provstr ) fail and return the following error message:
Msg 7416, Level 16
Access to the remote server is denied because no login-mapping exists.
A stricter connection validation check in the Database Engine can reject connections for certain linked server configurations that use the MSDASQL provider, even if earlier builds allowed those connections.
