Segregate odbc connection

I would like to show certain odbc connections only to specific users on a terminal server. For example, I have an Access db that has an sql back-end. All users can see the production database. I would like the development team to be able to see the test db without the regular users being able to see it. Currently all odbc connections are in the system dsn so everyone can see all of them. Is there are way, maybe using file or user dsn that I can accomplish this? Thanks.
