You will not be able to use Pass-Through authentication in this fashion with SQL Server. That works with file shares and even authenticating people via web apps, but SQL Server itself treats the local machine like a DOMAIN and accounts with the same username/password are not the same across machines.

2. Move the machines to a domain and use a service account

Your best bet is to go with SQL Server Integrated Authentication.
