There are multiple overloads for the ObjectContext constructor.

The default one just takes the connectionstring with a matching name from the config file. But you can also use a constructor where you specify the connection string yourself.

In your code you could maybe create a Authorization enum with values like BasicUser, Admin and pas that to your ConnectionClass. There you could do a switch and pick the right connection string from your config.
