I try and try. I can't find anything working for me. I simply want, when a domain user goes to the www page (ASP.NET and C#.NET), gets a list of members of a particiular group. Any hints, code examples?

IIS is on Windows Server 2003 SP2, LDAP is on Windows Server 2008 R2

Pls help!

Here is the LDIFDE command (LDAP query).

I am not a C# coder - but it may help.

Say your domain is DomainName.Domain.Com
The container is ContainerName

ldifde -f D:\ldif_grpexport.ldf -d "OU=ContainerName,OU=DomainName,DC=Domain,DC=Com" -r "(&(objectCategory=group)(displayName=name-of-group))" -l "DN,objectClass,cn,displayName"

Use Code:

using System.DirectoryServices;

ArrayList GetADGroupUsers(string groupName)
{    
   SearchResult result;
   DirectorySearcher search = new DirectorySearcher();
   search.Filter = String.Format("(cn={0})", groupName);
   search.PropertiesToLoad.Add("member");
   result = search.FindOne();

   ArrayList userNames = new ArrayList();
   if (result != null)
   {
       for (int counter = 0; counter < 
          result.Properties["member"].Count; counter++)
       {
           string user = (string)result.Properties["member"][counter];
               userNames.Add(user);
       }
   }
   return userNames;
}

Are you referring to a Security Group, like "Domain Admins", or an Organizational Unit (i.e. the containers in the tree, on the left, when viewing in Active Directory Users & Computers)?  There are distinctly different things, and the code will be different for each.

tgerbert,

Yes, im talking about security groups. I setup a new security group which is a role in my app. In one case I need to check if user logged to his computer attached to the domain is in the group and also I need to list members from this group.

Here's a simple console application example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.DirectoryServices;
using System.Collections;

namespace ConsoleApplication1
{
	class Program
	{
		static void Main(string[] args)
		{
			string[] users = GetGroupMembers(Environment.UserDomainName, "Domain Admins");

			foreach (string user in users)
				Console.WriteLine(user);

			Console.ReadKey();
		}

		static string[] GetGroupMembers(string DomainName, string GroupName)
		{
			List<string> members = new List<string>();

			// Get the group's directory entry
			using (DirectoryEntry group = new DirectoryEntry(String.Format("WinNT://{0}/{1},group", DomainName, GroupName)))
			{

				// Add members' names to members list
				foreach (object member in (IEnumerable)group.Invoke("Members"))
				{
					using (DirectoryEntry memberEntry = new DirectoryEntry(member))
					{
						members.Add(memberEntry.Name);
					}
				}
			}

			return members.ToArray();
		}
	}
}

The following code will give you various details.  If you put a break point on the results you can see a list of all properties (if you comment out all of the search.PropertiesToLoad) that are available to you.
DirectorySearcher search = new DirectorySearcher(domain);
            search.Filter = "(SAMAccountName=" + user + ")";
            search.PropertiesToLoad.Add("alias");
            search.PropertiesToLoad.Add("memberOf");
            search.PropertiesToLoad.Add("mail");
            search.PropertiesToLoad.Add("physicalDeliveryOfficeName");
            search.PropertiesToLoad.Add("cn"); // surname
            search.PropertiesToLoad.Add("sn"); // surname
            SearchResultCollection results = search.FindAll();
            if (results != null)
            {
                foreach (SearchResult result in results)
                {
                    foreach (ResultPropertyValueCollection property in result.Properties.Values)
                    {
                        foreach (object obj in property)
                        {
                            lstGroups.Items.Add(obj.ToString());
                        }
                    }
                }
            }

Do you mean you want to get these details while listing the members of a group? Or separately on a user-by-user basis?
