针对活动目录中的用户进行身份验证？

Question

我确实有一个Web应用程序，其中有一个登录页面。如何对活动目录用户进行身份验证？

到目前为止，我已经能够从活动目录中获取一些属性，这表明我能够使用LDAP字符串与AD通信。我知道无法从AD中提取密码并针对用户输入的密码进行身份验证！

有什么方法可以对活动目录用户进行身份验证吗？

到目前为止，这是我的代码

     public class Userdetails
{
    public static string ADPath = ConfigurationManager.AppSettings.Get(“ADPath”); // Get the ADAM Path from web config fiel
    public static string ADUser = ConfigurationManager.AppSettings.Get(“ADUser”); //ADAM Administrator
    public static string ADPassword = ConfigurationManager.AppSettings.Get(“ADPassword”); //ADAM Administrator  password

public static DirectoryEntry GetUserDetails(string userID)
{
        AuthenticationTypes AuthTypes;  // Authentication flags.
        // Set authentication flags.
        // For non-secure connection, use LDAP port and
        //  ADS_USE_SIGNING |
        //  ADS_USE_SEALING |
        //  ADS_SECURE_AUTHENTICATION
        // For secure connection, use SSL port and
        //  ADS_USE_SSL | ADS_SECURE_AUTHENTICATION
        AuthTypes = AuthenticationTypes.Signing |
            AuthenticationTypes.Sealing |
            AuthenticationTypes.Secure;
        DirectoryEntry De = new DirectoryEntry(ADPath, ADUser, ADPassword, AuthTypes);
    DirectorySearcher Ds = new DirectorySearcher(De);
    SearchResult Sr;
    Ds.SearchScope = SearchScope.Subtree;
    Ds.Filter = “(&(objectclass=*)(cn= ” + userID + “))”;
    Sr = Ds.FindOne();
    if (!(Sr == null))
    {
        De = new DirectoryEntry(Sr.Path, ADUser, ADPassword, AuthTypes);
        return De;
    }
    else
    {
        return null;
    }
}

如果您仅要针对AD进行身份验证，而不必执行其他特定于AD的操作，为什么不坚持使用内置的ActiveDirectoryMembershipProvider而不是编写自定义代码呢？

使用密码创建一个新的DirectoryEntry并将其与DirectorySearcher一起使用将验证密码并在密码失败时引发异常。 一个重要的例外是空/空密码。 如果LDAP参数为null或为空，则大多数LDAP服务器（我认为都包含AD）将忽略password参数。 因此，您应该首先进行测试。
