Answer 1

If you're on .NET 3.5 and up and using Microsoft's Active Directory as your LDAP store, you should check out the System.DirectoryServices.AccountManagement (S.DS.AM) namespace. Read all about it here:

• Managing Directory Security Principals in the .NET Framework 3.5
• MSDN docs on System.DirectoryServices.AccountManagement

Basically, you can define a domain context and easily find users and/or groups in AD:

// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// find a user
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "SomeUserName");

if(user != null)
{
   // do something here, e.g. get the user's e-mail address(es)
}

The new S.DS.AM makes it really easy to play around with users and groups in AD!

Most of the functionality I've used is in System.DirectoryServices.

Have a look at this link for more info: http://lozanotek.com/blog/articles/149.aspx

The LDAP link is basically a reference to a directory server, such as Active Directory, which will give you email addresses if you have their user name, for example. I'd start off by reading the article above, then experimenting with a small test program
