Note: because of crowd authentication, it can be problematic to run tDAR outside of ASU for testing. The easiest way to handle this is to setup a SSH tunnel from your machine to tDAR's primary machine:
in Putty: http://www.cs.uu.nl/technical/services/ssh/putty/puttyfw.html
ssh -L 8090:dev.tdar.org:80 username@beta.tdar.org
