I had a lot of trouble using impersonation with the PSI web services in Project Server 2007. I found some posts on the web suggesting that you need to add the account to the Process Accounts with Access to the SSP textbox, but guess what? That box was nowhere to be found!

Currently I am working on a project which uses Microsoft Project Server 2007. However, the SDK is poorly documented. Today I was looking at the Admin web service which can be used to configure settings on the server. In this article I am not going in to detail how to do this yourself, but the details that I have discovered.
