Connect to ApacheDS using C# and Novell Directory Ldap library

connectToApacheDS.cs

// HOWTO
// 1. Bring up docker, get the image xaked/apacheds:latest
// 2. Make sure to expose the port, here i use 10389
// 3. Open Apache Directory Studio, try connect to the server. use username = uid=admin,ou=system, password = secret (from xaked/apacheds)
// 4. If can connect, create a few entries. see http://krams915.blogspot.com/2011/01/ldap-apache-directory-studio-basic.html as example
// 5. look at the code, below. look at documentation https://www.novell.com/documentation/developer/ldapcsharp/?page=/documentation/developer/ldapcsharp/cnet/data/front.html


using Novell.Directory.Ldap;

LdapConnection connection = new LdapConnection();

try
{
    Console.WriteLine("Connecting to localhost:10389");
    // Set the server address and port
    connection.Connect("localhost", 10389); // Use 636 for LDAPS

    // Authenticate with the server
    connection.Bind("uid=admin,ou=system", "secret");

    // see documentation in item 5
    string searchBase = "o=testing";
    int searchScope = LdapConnection.ScopeSub; 
    string searchFilter = "(o=testing)";

    var lsc = connection.Search(searchBase, searchScope, "objectClass=*", null, false);

    while (lsc.HasMore())
    {
        LdapEntry nextEntry = null;
        try
        {
            nextEntry = lsc.Next();
        }
        catch (LdapException e)
        {
            Console.WriteLine("Error: " + e.LdapErrorMessage);
            //Exception is thrown, go for next entry
            continue;
        }

        Console.WriteLine("\n" + nextEntry.Dn);
        // Get the attribute set of the entry
        LdapAttributeSet attributeSet = nextEntry.GetAttributeSet();
        System.Collections.IEnumerator ienum = attributeSet.GetEnumerator();

        // Parse through the attribute set to get the attributes and the corresponding values
        while (ienum.MoveNext())
        {
            LdapAttribute attribute = (LdapAttribute)ienum.Current;
            string attributeName = attribute.Name;
            string attributeVal = attribute.StringValue;
            Console.WriteLine(attributeName + "value:" + attributeVal);
        }
    }
}
catch (LdapException ex)
{
    Console.Write("{0} {1}", ex.Message, ex.InnerException?.Message);
    // Handle LDAP exceptions...
}
finally
{
    // Close the connection
    connection.Disconnect();
