In a previous post I have written about Using the people picker over a one-way trust. In this post I use STSADM commands as there are no other ways to configure this. A downside of the STSADM command is your domain password being visible on the command prompt in clear text for everybody to read, or to retrieve from the command line history. SharePoint 2010 introduces several cmdlets to replace the “old” STSADM commands. Microsoft has posted an overview of the STSADM to Windows PowerShell mapping. However the commands for configuring the people picker are not available.

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 find!
