对活动目录中的用户进行身份验证

本文关键字：用户 身份验证 活动 | 更新日期: 2023-09-27 18:13:06

我确实有一个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?

到目前为止，我能够从活动目录中获得一些属性，这表明我能够通过LDAP字符串与AD通信。我知道从AD中提取密码并根据用户输入的密码进行身份验证是不可能的!!

是否有一种方法可以验证活动目录用户?

这是我到目前为止的代码

     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;
    }
}

        try
        {
            using (PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, Configuration.Config.ActiveDirectory.PrimaryServer, Configuration.Config.ActiveDirectory.Container, ContextOptions.Negotiate))
            {
                return principalContext.ValidateCredentials(username, password);
            }
        }
        catch (PrincipalServerDownException)
        {
            Debug.WriteLine("PrimaryServer={0};Container={1}", Configuration.Config.ActiveDirectory.PrimaryServer, Configuration.Config.ActiveDirectory.Container);
            Debug.WriteLine("LDAP://{0}/{1}", Configuration.Config.ActiveDirectory.PrimaryServer, Configuration.Config.ActiveDirectory.Container);
            throw;
        }

如果您只针对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?

请查看:

http://msdn.microsoft.com/en-us/library/system.web.security.activedirectorymembershipprovider.aspx

创建带有密码的新DirectoryEntry并将其与DirectorySearcher一起使用将验证密码，如果失败则抛出异常。一个重要的例外是空/空密码。大多数LDAP服务器(我认为包括AD)将忽略密码参数，如果它为空或空。所以你应该先测试一下。
