Connectivity to Microsoft SQL Servers

Question

I've recently been exposed to Oracle SQL Developer and have managed to connect to a remote MS SQL Database using the SQL Server TAB (Using Windows Authentication).
I was wondering if there was/is a way to use an Active Directory account to connect to the MS SQL Database that is not the account you are currently logged in as.
For Example
UserA is logged into the Windows client machine, but doesn't have access to the MS SQL Database.
UserB has an account which does have MS SQL Database access but cannot login to the client machine.
UserA know's UserB's account details. Where if at all can UserA put UserB's credentials in to allow connectivity?
Thanks

The easiest (and cheapest) way is to use the JDBC/ODBC bridge that ships with the JDK.
To register the driver within your application you just load the class into memory like this:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
You now need to create an ODBC datasource for the database connection. Go into the control panel and ODBC control panel program to create a datasource (most people create a system DSN). Make a note of the name you give it (say MYDSN for example).
Now, to get a connection you use the following line:
Connection c=DriverManager.getConnection("jdbc:odbc:MYDSN",username,password);
If you've set the username and password for the DSN in the control panel (as you can for SQL Server) then you can use just say:
Connection c=DriverManager.getConnection("jdbc:odbc:MYDSN");
