C# error when connecting to ldap server that does not exist

Question

When using Novell.Directory.Ldap.dll and making a connect to an ldap
server which does not exists i'm getting the following error:
Connection.freeWriteSemaphore(-2): semaphore not owned by any thread
Im using this to connect: conn.Connect(ldapHost, ldapPort);
This error is not catched by LdapException. Can anyone tell me if this is
a bug or do I have to do something different.

Hi. I'm using version 2.1.11 of the NDK for CSharp. I'm getting this
same error message:
Code:
Connection.freeWriteSemaphore(-2): semaphore not owned by any thread
at Novell.Directory.Ldap.Connection.freeWriteSemaphor e(Int32 msgId)
at Novell.Directory.Ldap.Connection.connect(String host, Int32 port, Int32 semaphoreId)
at Novell.Directory.Ldap.LdapConnection.Connect(Strin g host, Int32 port)
at TestLDAP.Program.Main(String[] args) in D:\Documents and Settings\tjbuege\my documents\visual studio 2010\Projects\TestLDAP\TestLDAP\Program.cs:line 20
This occurs when I try to bind to a server that does not exist. Here
is my sample source code that generates that error:
Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Novell.Directory.Ldap;
namespace TestLDAP
class Program
static void Main(string[] args)
LdapConnection conn = null;
string host = "server.does.not.exist.com";
int port = 389;
try
conn = new LdapConnection();
conn.Connect(host, port);
catch (Exception ex)
Console.WriteLine(ex.Message);
Console.WriteLine(ex.StackTrace);
if (conn != null)
conn.Disconnect();
Is there a fix for this? It makes this library useless for me.
Thanks,
Tim
