c# - Active Directory 中的 userAccountControl

Question

我想知道 userAccountControl 的当前值并确定它处于哪个阶段

参考： http: //support.microsoft.com/kb/305144/en-us

根据上述文档，它应该返回 2 的 N 次幂。

但是当我运行我的 c# 程序时，它为普通帐户返回值 544，为禁用帐户返回 546。我怀疑它们是十进制数字。但是我如何链接回参考中显示的值？

谢谢。

您可以通过将结果转换为枚举来轻松解码。

int userAccountControlValue = 544;
UserAccountControl userAccountControl = (UserAccountControl) userAccountControlValue;

// This gets a comma separated string of the flag names that apply.
string userAccountControlFlagNames = userAccountControl.ToString();

// This is how you test for an individual flag.
bool isNormalAccount = (userAccountControl & UserAccountControl.NORMAL_ACCOUNT) == UserAccountControl.NORMAL_ACCOUNT;
bool isAccountDisabled = (userAccountControl & UserAccountControl.ACCOUNTDISABLE) == UserAccountControl.ACCOUNTDISABLE;
bool isAccountLockedOut = (userAccountControl & UserAccountControl.LOCKOUT) == UserAccountControl.LOCKOUT;

这是您想要的枚举定义：

它是一个位图。一个字中的每一位要么为 ON，要么为 OFF（0 或 1）。它并不是一个真正的数字，它更像是一排开关，每个开关都打开或关闭。操作系统在内部使用它们，因为它们可以通过将它们与位掩码进行逻辑比较来非常快速地操作它们。

属性的 LDIF 表示可以将结果显示为十进制数（相当于如果它是一个数字将由掩码表示的二进制数 - 它不是真的！）而且它很容易解码，因为基本上它通过将 2 的一些幂加在一起制成。

例如：

  512 = normal account
  514 = 512 + 2 = normal account, disabled
  546 = 512 + 32 + 2 = normal account, disabled, no password required
 2080 = 2048 + 32 = Interdomain trust, no password required
66048 = 65536 + 512 = normal account. password never expires
66050 = 65536 + 512 + 2 = normal account. password never expires, disabled
66080 = 65536 + 512 + 32 = normal account. password never expires, no password required

544 = 十六进制 0x220
546 = 十六进制 0x222

根据此处的列表，这意味着：

0x200 = normal account
0x020 = passwd_notreqd = password not required
0x002 = account disabled

所以

值 544（十进制）是0x220十六进制，表示：普通帐户，不需要密码
值 546（十进制）是0x222十六进制，表示：普通帐户、禁用、不需要密码

Python function to decode Active Directory userAccountControl.

define a dictionary with all the defined combination. (ref. Microsoft)

uac_decode_dict = {"0x0001": "SCRIPT",
               "0x0002": "ACCOUNTDISABLE",

               "0x04000000": "PARTIAL_SECRETS_ACCOUNT"}

define a function to decode the UAC value

def decode_uac(_uac):
#
# Decode the userAccountControl value.
#

global uac_decode_dict

_translatedUAC = ""
_hex_uac = hex(_uac)

_hu_work = _hex_uac[2:]
_x = 0
for _hu in _hu_work[::-1]:
    _x += 1
    _hu_tmp = ""
    if _hu != "0":
        _hu_tmp = _hu.ljust(_x, "0")
        if len(_hu_tmp) <= 3:
            _hu_tmp = "".ljust(4 - _x, "0") + _hu_tmp
        _hu_key = r"0x" + _hu_tmp
        if _hu_key in uac_decode_dict.keys():
            if _translatedUAC == "":
                _translatedUAC += uac_decode_dict[_hu_key]
            else:
                _translatedUAC += " - " + uac_decode_dict[_hu_key]
        else:
            print("Invalid userAccountControl key: " + str(_hu_key) + ". Values dec: " + str(_uac) + " hex: " + _hex_uac)
            _translatedUAC += " - Error "

return _translatedUAC

call the function passing the userAccountControl as an Integer
```
result = decode_uac(int(_userAccountControl))
```
