C#.net using active directory
In an existing C#.net 2008 windows form application, I want to add some security
features. Thus, I have the following questions:
1. What are the options available for adding security to this C#.net
application and what is the preferred method?
2. I have heard about using the active directory in C#.net applications. Thus,
can you suggest urls (links) that I can use as a reference?
