What you want is pretty hard as long as the data source is not centrally 
protected with a password. That is you have a database on a server you 
only access, there is a central db but access to it is restricted to the 
admin, everybody else has a unique login name and a 'personal' database 
which is a view on the central database.
Authentication must be done with any of the single sign on solutions 
available, probably the most likely one is Microsoft's kerberos 
implementation.

However it might be good enough to fetch the username from the 
environment variables and use that to build custom queries inside your 
application to get the data from the central resource.

As long as somebody is not using your standard database credentials to 
directly go to the data or fiddles with your program and changes the 
part where it fetches the username from the environment, you should have 
hidden the security flaw sufficiently to appear to be protected.
