针对活动目录中的用户进行身份验证？

Question

我有一个Web应用程序,我有一个登录页面.如何对活动目录用户进行身份验证？

截至目前,我能够从活动目录中获取一些属性,最后我能够使用LDAP字符串与AD进行通信.我知道无法从AD中提取密码并根据用户输入的密码进行身份验证!!

有没有办法可以对活动目录用户进行身份验证？

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;
    }
}
