如何确定用户帐户是否启用或禁用

Question

我正在编写一个快速的 C# win 表单应用程序来帮助解决重复性的文书工作。

我已在 AD 中搜索所有用户帐户，并将它们添加到带有复选框的列表视图中。

我想默认 listviewitems 的默认检查状态取决于帐户的启用/禁用状态。

string path = "LDAP://dc=example,dc=local";
DirectoryEntry directoryRoot = new DirectoryEntry(path);
DirectorySearcher searcher = new DirectorySearcher(directoryRoot,
    "(&(objectClass=User)(objectCategory=Person))");
SearchResultCollection results = searcher.FindAll();
foreach (SearchResult result in results)
{
    DirectoryEntry de = result.GetDirectoryEntry();
    ListViewItem lvi = new ListViewItem(
        (string)de.Properties["SAMAccountName"][0]);
    // lvi.Checked = (bool) de.Properties["AccountEnabled"]
    lvwUsers.Items.Add(lvi);
}

我正在努力寻找正确的属性来解析以从 DirectoryEntry 对象获取帐户的状态。我搜索了AD用户属性，但没有找到任何有用的东西。

有人可以指点一下吗？

Answer 1

这里的代码应该可以工作...

private bool IsActive(DirectoryEntry de)
{
  if (de.NativeGuid == null) return false;

  int flags = (int)de.Properties["userAccountControl"].Value;

  return !Convert.ToBoolean(flags & 0x0002);
}

Answer 2

使用System.DirectoryServices.AccountManagement： 域名和用户名必须是域名和用户名的字符串值。

using (var domainContext = new PrincipalContext(ContextType.Domain, domainName))
{
    using (var foundUser = UserPrincipal.FindByIdentity(domainContext, IdentityType.SamAccountName, username)) 
    {
        if (foundUser.Enabled.HasValue) 
        {
            return (bool)foundUser.Enabled;
        }
        else
        {
            return true; //or false depending what result you want in the case of Enabled being NULL
        }
    }
}

Answer 3

没有人问，但这里有一个 java 版本（因为我最终在这里寻找一个）。空检查留给读者作为练习。

private Boolean isActive(SearchResult searchResult) {
    Attribute userAccountControlAttr = searchResult.getAttributes().get("UserAccountControl");
    Integer userAccountControlInt = new Integer((String) userAccoutControlAttr.get());
    Boolean disabled = BooleanUtils.toBooleanObject(userAccountControlInt & 0x0002);
    return !disabled;
}

Answer 4

你可以使用这样的东西：

    ADUserAccountControl flags;
    Enum.TryParse(de.Properties["userAccountControl"].Value.ToString(), out flags);

    if(flags.HasFlag(ADUserAccountControl.ACCOUNTDISABLE)
    {
        // account is disabled
    }

这里是所有可能标志的完整列表：

    /// <summary>
    /// Source: https://learn.microsoft.com/en-us/troubleshoot/windows-server/identity/useraccountcontrol-manipulate-account-properties
    /// </summary>
   [Flags]
   public enum ADUserAccountControl : long
   {            
        SCRIPT = 0x0001,
        ACCOUNTDISABLE = 0x0002,
        HOMEDIR_REQUIRED = 0x0008,
        LOCKOUT = 0x0010,
        PASSWD_NOTREQD = 0x0020,
        PASSWD_CANT_CHANGE = 0x0040,
        ENCRYPTED_TEXT_PWD_ALLOWED = 0x0080,
        TEMP_DUPLICATE_ACCOUNT = 0x0100,
        NORMAL_ACCOUNT = 0x0200,
        INTERDOMAIN_TRUST_ACCOUNT = 0x0800,
        WORKSTATION_TRUST_ACCOUNT = 0x1000,
        SERVER_TRUST_ACCOUNT = 0x2000,
        DONT_EXPIRE_PASSWORD = 0x10000,
        MNS_LOGON_ACCOUNT = 0x20000,
        SMARTCARD_REQUIRED = 0x40000,
        TRUSTED_FOR_DELEGATION = 0x80000,
        NOT_DELEGATED = 0x100000,
        USE_DES_KEY_ONLY = 0x200000,
        DONT_REQ_PREAUTH = 0x400000,
        PASSWORD_EXPIRED = 0x800000,
        TRUSTED_TO_AUTH_FOR_DELEGATION = 0x1000000,
        PARTIAL_SECRETS_ACCOUNT = 0x04000000,
    }

Answer 5

我来这里寻找答案，但只是为了

DirectoryEntry

。所以这里有一个适用于

SearchResult

/

SearchResultCollection

的代码，对于有同样问题的人来说：

private bool checkIfActive(SearchResult sr)
{
    var vaPropertiy = sr.Properties["userAccountControl"];

    if (vaPropertiy.Count > 0) 
    {
        if (vaPropertiy[0].ToString() == "512" || vaPropertiy[0].ToString() == "66048") 
        {
            return true;
        } 
        
        return false;
    }

    return false;
}
