我安装并配置了运行ldap的ApacheDS服务器。这对我自学ldap来说是一个巨大的进步。但是,以下C#控制台代码返回以下错误:
System.DirectoryServices.Protocols.LdapException {"The supplied credential is invalid"}
我的代码是使用此示例代码对示例用户进行身份验证。
Program.cs的
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SampleLdapAuthentication
{
class Program
{
static void Main(string[] args)
{
RunLdap run = new RunLdap("localhost", "organization", 635, "hderp", "spaceballs1234");
bool result = run.ValidateCredentials();
if(result)
{
Console.WriteLine("Authentication Succeeded");
}
else
{
Console.WriteLine("Authentication Failed");
}
}
}
}
SampleLdapAuthentication.cs
using System;
using System.Collections.Generic;
using System.DirectoryServices.Protocols;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
namespace SampleLdapAuthentication
{
public class RunLdap
{
private static string _domainController;
private static string _domain;
private static int _port;
private static string _userName;
private static string _userPassword;
//Constructor. Takes the domain controller, domain, port, username, and password and then calls Ldap Method to run authentication
public RunLdap(string domainController, string domain, int port, string userName, string userPassword)
{
_domainController = domainController;
_domain = null;
_port = port;
_userName = userName;
_userPassword = userPassword;
}
public bool ValidateCredentials()
{
LdapDirectoryIdentifier ldi = new LdapDirectoryIdentifier(_domainController, _port);
NetworkCredential networkCredential = new NetworkCredential(_userName, _userPassword, _domain);
try
{
//We use using so we dispose the object as soon as it goes out of scope
using (LdapConnection connection = new LdapConnection(ldi))
{
//connection.SessionOptions.SecureSocketLayer = true;
connection.AuthType = AuthType.Kerberos;
connection.Bind(networkCredential);
//Not sure what this is doing
}
return true;
}
catch(LdapException ldapException)
{
return false;
}
return false;
}//End of ValidateCredentials
}
}
LDAP服务器详细信息
以下是值得注意的事情:
AuthType
我想也许我输入凭据并且我的C#代码没问题。这就是我包含服务器AD信息的原因。我是LDAP的新手并使用它来验证用户身份,所以感谢您的帮助。
答案 0 :(得分:1)
您没有使用用户的专有名称。在创建NetworkCredential
对象时,您应该使用用户的distingushed名称,在这种情况下,cn=Herp Derp,ou=users,o=organization
而不是hderp
。在没有hderp
和o
值的情况下,LDAP无法知道查找ou
的位置。
