Using embedded test users while in an AD environment

Our Jazz server is AD connected (Windows 2003) and our normal users use AD accounts. The community wants to use the canned test users for the JKE Banking project just like in their training so they can continue playing.

The only thing I can see, is to create new AD accounts for the test users. This isn't desireable and would like to know if there's a way to leverage both the local accounts for the test project and the AD accounts for real projects.

Thanks in advance!
