In an MS Access database I have tables linked from SQL Server via an ODBC bridge. The bridge is set up with SQL Authentication. However when I link a table to this Access database I can use either the SQL user name and password or Trusted Connection. Either way the table is accessible. The connection strings are below for the same table. Is this normal ? If the bridge is set up with SQL Authentication I thought that is the way the SQL tables had to be linked. Trying to understand how this works so I can set up other clients. Thanks.
