PS2010 Solution Starter - Unauthorized 401

Couple of tools (Bulk Edit / Import) in the Project Server 2010 Solution Starter, do not work in a load balanced environment and result in 401 Unauthorized exception.

Solution: This is due to double hop issue arising out of PSI calls in the code.
Here are the various options,
1. Implement Kerberos on the farm (production solution)
2. Implement AAM to point all requests to one of the servers in the farm.
    - Set up public url in the internet zone.
    - Set up IIS bindings on all servers to point to the 1 server which will server content.
    - IIS reset

*Make sure the project web access application pool account is a project server administrator on the pwa instance.
