I am trying to use LDAP to get information about domain controllers and to know about its status and Replication status using C#. I am trying to do this approach remotely; for example, I am running code in PC1 and would like to know and get information from PC2 .
I know when using WMI, it is possible to get information using the following queries:
SELECT * FROM MSAD_DomainController
then
SELECT * FROM MSAD_ReplCursor where SourceDsaDN like '%{domainControllerName}%'
then
SELECT * FROM MSAD_ReplNeighbor where NamingContextDN like '{NamingContextDN->From above query}'
So what would I need to get information similar to the WMI query when using LDAP?
I am using this code to look into the details of domain controller
using System.DirectoryServices;
using System.DirectoryServices.ActiveDirectory;
class Program
{
static void Main()
{
string domainname = {Domain};
string username = {User};
string password = {Pass};
try
{
// Using DirectoryEntry for LDAP operations
string ipAddress = {IP};
string ldapPath = $"LDAP://{ipAddress}:389/DC={domainname},DC=com";
using (DirectoryEntry entry = new DirectoryEntry(ldapPath, username, password, AuthenticationTypes.Secure))
{
using (DirectorySearcher searcher = new DirectorySearcher(entry))
{
searcher.Filter = "(objectClass=*)";
searcher.SearchScope = SearchScope.Subtree;
SearchResultCollection results = searcher.FindAll();
if (results.Count == 0)
{
Console.WriteLine("No objects found.");
}
else
{
foreach (SearchResult result in results)
{
Console.WriteLine("Object Information:");
if (result.Properties["objectClass"].Count > 0)
{
Console.Write($"Object Class: ");
foreach (var value in result.Properties["objectClass"])
{
Console.Write($"{value}, "); // Print each value
}
}
foreach (string propertyName in result.Properties.PropertyNames)
{
var propertyValues = result.Properties[propertyName];
if (propertyValues.Count > 0)
{
Console.Write($"{propertyName}: ");
foreach (var value in propertyValues)
{
Console.Write($"{value}, "); // Print each value
}
Console.WriteLine(); // New line after values
}
else
{
Console.WriteLine($"{propertyName}: Not Available or Empty");
}
}
Console.WriteLine("---------------------------------------------------");
}
}
}
}
}
catch (ActiveDirectoryObjectNotFoundException ex)
{
Console.WriteLine($"Error: {ex.Message} - Check domain name and connectivity.");
}
catch (ActiveDirectoryOperationException ex)
{
Console.WriteLine($"AD Operation Error: {ex.Message}");
}
catch (DirectoryServicesCOMException ex)
{
Console.WriteLine($"Directory Services Error: {ex.Message}");
}
catch (Exception ex)
{
Console.WriteLine($"Unexpected Error: {ex.Message}");
}
}
}
