Using Active Directory Searching/Lookup in a SharePoint/MOSS 2007 Workflow (with Visual Studio 2008)

This is the eighth in a series (the series is listed at the bottom) of "How To " Videos that I have created to show .NET Developers how to build document workflow in a SharePoint environment. 

In the How to Videos that I produced on "Building Approval Workflow's" and "Escalating Workflow's (for overdue tasks), I kept things simple (focusing on the Workflow) and did not do dynamic lookups of people/users against Active Directory (AD), choosing to "hard code" the users in the workflow.

In this example, I take one of those workflow's (Basic Approval Workflow) and show you how you can do a "Dynamic Lookup or Search" of Active Directory for information (The Manager of a user) using .NET Code (System.DirectoryServices).

Nice demo, but do not use Web.AllUsers collection to retrieve the SPUser Object from SharePoint.

use Web.SiteUsers to retrieve a SPUser Object.

reason:
if the user never loged in to the SharePoint Site on which the workflow is runing he/she will not be in the AllUsers collection and you will get an exception.
