InfoPath Dev

Don't know if I should put this into the old http://www.infopathdev.com/forums/topic.asp?TOPIC_ID=554thread but anyway.

As I couldn't get it work I came up with another solution. I wrote a small WebService and read all members from a AD group, or better the eMail addresses of them. In my InfoPath document I populate a DDL with theses values using the connection wirzard for WebServices. Not exactly what I wanted to have but still better than nothing.
The basics I found here http://forums.asp.net/thread/1159654.aspx and I tailored it to my belongings. For those who are interested here is the code I am using for my WebService:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.DirectoryServices;
using System.Text;
using System.Diagnostics;
using System.Web;
using System.Xml;
using System.Web.Services;

namespace GetADGroupMembers
{
	public class Service1 : System.Web.Services.WebService
	{
		public Service1()
		{
			InitializeComponent();
		}

		private IContainer components = null;
				
		private void InitializeComponent()
		{

		}

		protected override void Dispose( bool disposing )
		{
			if(disposing && components != null)
			{
				components.Dispose();
			}
			base.Dispose(disposing);		
		}

		//for repeating structure
		public struct MemberMail
		{
			public string eMail;
		}

		[WebMethod]
		public MemberMail[] GetMemberMail()
		{
			MemberMail[] mails = null;
			

			DirectoryEntry group = new DirectoryEntry(
				"LDAP://CN=ADGroupName,OU=ThirdOU(group is in this OU),OU=SecondOU,OU=TopOU Worldwide,DC=dc1,DC=dc2,DC=dc3", //change this how you need it
				null,
				null,
				AuthenticationTypes.Secure
				);

			StringBuilder sb = new StringBuilder();
			
			sb.Append("(|");

			using (group)
			{
				foreach (string s in group.Properties["member"])
				{
					sb.AppendFormat("(distinguishedName={0})", s);
				}
			}
			
			sb.Append(")");

			DirectoryEntry searchRoot = new DirectoryEntry(
				"LDAP://dc=corp,dc=huskyims,dc=com",
				null,
				null,
				AuthenticationTypes.Secure
				);
    
			using (searchRoot)
			{
				DirectorySearcher ds = new DirectorySearcher(
					searchRoot,
					sb.ToString(), 
					new string[]{"mail"} // read here what ever you want e.g. nick samaccountname etc.
					);
        
				using (SearchResultCollection src = ds.FindAll())
				{
					mails = new MemberMail[src.Count];
					int i = 0;
					foreach (SearchResult sr in src)
					{
						foreach (string key in sr.Properties.PropertyNames)
						{
							if(key == "adspath")
							{
							}
							else
							{
								foreach (object o in sr.Properties[key])
								{
									mails.eMail = o.ToString();
									i++;
								}
							}
						}
					}
				}
				return mails;
			}
		}
        }
}

That's it may be someone can use it

Thanks for sharing this with us!
