如何在.NET中验证LDAP

using System;
using System.DirectoryServices.Protocols;

public bool ValidateLDAPCredentials(string username, string password)
{
    try
    {
        // 设置LDAP服务器地址和端口
        string ldapServer = "ldap://your-ldap-server:389";
        string ldapUserDn = "cn=" + username + ",dc=example,dc=com";

        // 创建LDAP连接
        LdapConnection ldapConnection = new LdapConnection(new LdapDirectoryIdentifier(ldapServer));

        // 设置LDAP连接凭据
        NetworkCredential ldapCredentials = new NetworkCredential(ldapUserDn, password);
        ldapConnection.Credential = ldapCredentials;

        // 尝试绑定LDAP连接
        ldapConnection.Bind();

        // 如果绑定成功，则返回true
        return true;
    }
    catch (LdapException)
    {
        // 如果绑定失败，则返回false
        return false;
    }
}
