Active Directory C# help

[laserpp]

Hello All,

Writting a new C# program to replace a very old VBS file. Pretty much the program will go through our AD and get all the users and their emails and put it in a CSV file. I found some basic code and ran it and I think it worked because I saw a huge list in the console but when it was finished it closed and gave me an error.

ERROR

        {
            DirectoryEntry entry = new DirectoryEntry("LDAP://OU=PHF Users,DC=phf,DC=inc");

            using (DirectorySearcher ds = new DirectorySearcher(entry))
            {
                ds.PropertiesToLoad.Add("name");
                ds.PropertiesToLoad.Add("userPrincipalName");

                ds.Filter = "(&(objectClass=user))";

                SearchResultCollection results = ds.FindAll();

                foreach (SearchResult result in results)
                {
                    Console.WriteLine("{0} - {1}",
                        result.Properties["name"][0].ToString(),
                        result.Properties["userPrincipalName"][0].ToString());
                }
            }

        }
    }
}

Any thoughts on it?


P.S. That just the basic code, trying to get it to work in the console before I add the CSV file and validations. Pretty new to this type of programming.

System.DirectoryServices.ActiveDirectory

 

[laserpp]

Dont have that in my references =/

 

[majestic1805]

So add it. As long as you ref to System.DirectoryServices you can declare using System.DirectoryServices.ActiveDirectory.

 

[laserpp]

the mail is still give me that same error

 

[majestic1805]

Are you sure that property exists in that domain? As in can you go to a domain controller, open up AD and view a user to see its mail entry?

 

[laserpp]

I got my other code running find for user names, need to just get the mail working adn exporting the info to a CSV file, my next steps

 

[laserpp]

Yup, have the ldp open and looking at a user and they have a mail: xxxxxxx@xxxxx.org

 

[majestic1805]

Well, it showed up earlier when you spit out the results of Properties. What if you drill into it like you did with cn?

 

[laserpp]

it not even just mail, any 2nd object i try to pull same error, only seems cn works

 

[laserpp]

heres the new code btw

using System;
using System.Collections.Generic;
using System.Text;
using System.DirectoryServices;
using Microsoft.Office.Interop.Excel;
using System.DirectoryServices.ActiveDirectory;


namespace EmailListing
{
    class Program
    {
        static void Main(string[] args)
        {
          

            DirectoryEntry adFolderObject = new DirectoryEntry("LDAP://OU=PHF Users,DC=phf,DC=inc");

            DirectorySearcher adSearchObject = new DirectorySearcher(adFolderObject);

            adSearchObject.SearchScope = SearchScope.Subtree;

            adSearchObject.Filter = "(&(ObjectClass=user)(!description=Built-in*))";

            foreach (SearchResult adObject in adSearchObject.FindAll())
            {
                Console.WriteLine("cn={0}", adObject.Properties["cn"][0]);
               // Console.WriteLine("co={0}", adObject.Properties["co"][0]);
               
            }

            Console.WriteLine();
            Console.ReadLine();
        }
    }
}

Did you try digging into name like you did with cn? Also, double check what permissions are setup as AD may not be sending that info as you may not be allowed to see anything except names.

 

[laserpp]

well done, i dug into it and its only bringing in 32 fields and mail isnt one of them. Now how do we get all the fields brought in lol

 

[majestic1805]

You'll need to research that one. Google is your friend.

 

[laserpp]

I found stuff on active direct schema, do I need to add a new using class for it? some of the schema options arent showing up

 

[majestic1805]

That's beyond my expertise, mate.

 

[laserpp]

alright thanks a lot for everything else
