Ldap连接抛出对象引用未设置为对象错误的实例

我正在尝试连接到LDAP以验证用户身份。这是我的代码，在将connction安全套接字层设置为true后，我在connection.connect期间遇到异常。

它抛出的异常对象引用未设置为对象的实例，我已创建了连接对象，但不知道出了什么问题。有人帮帮我吗？

using LdapConnection = Novell.Directory.Ldap.LdapConnection;
using LdapException = Novell.Directory.Ldap.LdapException;

 var ldapHost = WebConfigurationManager.AppSettings["LDAP_HOST"];
 var ldapPort = WebConfigurationManager.AppSettings["LDAP_PORT"];

 var connection = new LdapConnection {SecureSocketLayer = true};
 connection.Connect(ldapHost, Convert.ToInt32(ldapPort)); // Getting exception here object reference not set to an instance of an object.

 sb = new StringBuilder();
 sb.Append(ldapLocation).Append(userName).Append(",").Append(ldapLocationIndia);
 connection.Bind(LdapConnection.Ldap_V3, sb.ToString(), password);

请提前帮助，谢谢。

您的配置中是否正确设置了ldapHost和ldapPort？

connection.connect()抛出的异常是tpye LDAPException，所以我认为它甚至没有尝试连接。
