Error:Connect Error

[MuhammadNazmi12]

Hello, I have a problem with this library. I try to connect login page with ldap port 636. Then, when I test it show the error message 'Error: Connect Error'. I already follow the step from the samples, interactive ssl, securebind and starttls. I don't know why even though I follow steps, but it's doesn't work.

try
{ if (id == String.Empty) { IdTxt.Text = "Please insert your id"; }else if (pass == String.Empty) { PassTxt.Text = "Password Missing. Please insert you password"; } else { LdapConnection conn = new LdapConnection(); conn.SecureSocketLayer = true; conn.UserDefinedServerCertValidationDelegate += new RemoteCertificateValidationCallback(SSLHandler); conn.Connect(ldapHost, ldapPort); conn.StartTls(); conn.Bind(ldapVersion, id, pass); ErrorLabel.Text = " SSL Bind Successfull"; Response.Redirect("Logout", false); }

} catch(LdapException a) { //Console.WriteLine("Error: " + a.LdapErrorMessage); ErrorLabel.Text ="Error: " + a.Message; }

    }

    public bool SSLHandler(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)

        X509Certificate x509 = null;
        X509CertificateCollection coll = new X509CertificateCollection();
        byte[] data = certificate.GetRawCertData();
        if (data !=null)
        {
            x509 = new X509Certificate(data);
