BridgeHead

通过 ADWS 原生 C++ 访问 Active Directory，无需 .NET，无需 WCF，无需 HTTP 栈。

BridgeHead 是一个 C++20 静态库，直接在 TCP 之上实现完整的 Active Directory Web Services (ADWS) 协议栈。它得名于 AD 桥头服务器（目录流量流经的网关），为你的 C++ 代码提供与 PowerShell 的 Get-ADUser 和 Get-ADComputer 底层相同的对 9389 端口的低层访问能力。

协议栈

传输层通过公共的 bridgehead::transport::IByteStream 接口封装其下的一层。NbfseCodec 是一个编解码工具，由 AdwsClient 调用，用于在成帧之前和之后对 SOAP 消息进行编码/解码：``` AdwsClient WS-Enumeration + WS-Transfer [MS-ADDM] ├── NbfseCodec .NET Binary Format for SOAP [MC-NBFSE] (encode/decode) └── NmfFramer .NET Message Framing [MC-NMF] (send/receive frames) └── NnsSession .NET NegotiateStream [MS-NNS] └── TcpSocket raw TCP/IP

使用者的入口点是 `bridgehead::adws::AdwsClient`。

## 快速开始

### 查询并枚举所有用户```cpp
#include "bridgehead/adws/AdwsClient.hpp"

// NTLM (works on any host)
auto client = bridgehead::adws::AdwsClient::EnumerationClient(
    "192.168.1.10",     // DC IP or hostname
    "DC01.corp.local",  // DC FQDN, used in NMF Via header and Kerberos SPN
    "CORP",             // NetBIOS domain name
    "Administrator",    // username
    "Passw0rd"          // password
);

// Kerberos (username hidden on the wire; requires DC reachable on port 88)
auto client = bridgehead::adws::AdwsClient::EnumerationClient(
    "192.168.1.10", "DC01.corp.local", "CORP",
    "Administrator", "Passw0rd",
    bridgehead::adws::AuthPackage::Kerberos
);

auto users = client.Query(
    "(objectClass=user)",
    {"sAMAccountName", "distinguishedName", "memberOf"}
);

for (auto& obj : users)
    std::cout << obj.FirstValue("sAMAccountName") << '\n';

流式传输大型结果集```cpp

client.Enumerate( "(objectClass=computer)", {"dNSHostName", "operatingSystem"}, "", // empty = domain root base DN [](const bridgehead::adws::LdapObject& obj) { std::cout << obj.FirstValue("dNSHostName") << '\n'; return true; // return false to stop early (sends wsen:Release) } );

### 范围与分页```cpp
// OneLevel scope, 50 objects per Pull round-trip
client.Query(
    "(objectClass=user)",
    {"sAMAccountName"},
    "OU=Admins,DC=corp,DC=local",
    50,
    bridgehead::adws::SearchScope::OneLevel
);

二进制属性、objectGUID、objectSid```cpp

auto objs = client.Query("(objectClass=user)", {"objectGUID", "objectSid"}); for (auto& obj : objs) { if (auto* b = obj.FirstBytes("objectGUID")) std::cout << bridgehead::adws::ParseGuid(b) << '\n'; // {XXXXXXXX-...} if (auto b = obj.FirstBytes("objectSid")) std::cout << bridgehead::adws::ParseSid(*b) << '\n'; // S-1-5-... }

### 安全描述符解码```cpp
#include "bridgehead/adws/SecurityDescriptor.hpp"

auto objs = client.Query("(objectClass=user)", {"nTSecurityDescriptor"});
if (auto* raw = objs[0].FirstBytes("nTSecurityDescriptor")) {
    auto sd = bridgehead::adws::ParseSecurityDescriptor(*raw);
    std::cout << "Owner: " << sd.ownerSid << '\n';
    for (auto& ace : sd.dacl.aces)
        std::cout << "  type=" << (int)ace.type
                  << " mask=0x" << std::hex << ace.mask
                  << " sid="   << ace.sid << '\n';
}

写入属性（资源端点）```cpp

auto rc = bridgehead::adws::AdwsClient::ResourceClient( "192.168.1.10", "DC01.corp.local", "CORP", "Administrator", "Passw0rd");

// Modify attributes rc.Put("CN=Alice,OU=Users,DC=corp,DC=local", { {"description", {"managed by bridgehead"}}, {"telephoneNumber", {"555-1234"}}, });

// Clear an attribute (both values and bytes empty = delete) rc.Put("CN=Alice,OU=Users,DC=corp,DC=local", { {"telephoneNumber", {}}, });

// Read back auto obj = rc.Get("CN=Alice,OU=Users,DC=corp,DC=local", {"description", "telephoneNumber"});

// Delete object rc.Delete("CN=TempUser,OU=Users,DC=corp,DC=local");

### LDAP 修改类型：Add / Replace / Delete

`Put` 默认使用 `Replace`（覆盖所有现有值）。如需对多值属性进行精细控制，请使用 `ModifyOperation`：```cpp
using bridgehead::adws::LdapModification;
using bridgehead::adws::ModifyOperation;

rc.Put("CN=Alice,OU=Users,DC=corp,DC=local", {
    // Append a value to an existing multi-valued attribute
    LdapModification{"otherTelephone", {"555-9999"}, {}, ModifyOperation::Add},

    // Remove one specific value (leave others intact)
    LdapModification{"otherTelephone", {"555-0000"}, {}, ModifyOperation::Delete},

    // Replace is the default, explicit here for clarity
    LdapModification{"description", {"updated"}, {}, ModifyOperation::Replace},
});

移动 / 重命名```cpp

// Move to a different OU rc.Move( "CN=Alice,OU=OldOU,DC=corp,DC=local", // current DN "CN=Alice,OU=NewOU,DC=corp,DC=local" // new DN );

// Rename in place (same parent, new CN) rc.Move( "CN=Alice,OU=Users,DC=corp,DC=local", "CN=AliceSmith,OU=Users,DC=corp,DC=local" );

### 写入二进制属性

在 `LdapModification` 的 `bytes` 字段中提供二进制值。它们会在传输线上自动进行 base64 编码：```cpp
std::vector<uint8_t> thumbnail = loadFile("photo.jpg");

rc.Put("CN=Alice,OU=Users,DC=corp,DC=local", {
    LdapModification{"thumbnailPhoto", {}, {thumbnail}},
});

创建对象（ResourceFactory 端点）```cpp

auto rf = bridgehead::adws::AdwsClient::ResourceFactoryClient( "192.168.1.10", "DC01.corp.local", "CORP", "Administrator", "Passw0rd");

rf.Create( "CN=NewUser,OU=Users,DC=corp,DC=local", "user", {{"sAMAccountName", {"newuser"}}, {"userAccountControl", {"512"}}} );

### 异步操作```cpp
#include "bridgehead/adws/AdwsClientAsync.hpp"

auto ac = bridgehead::adws::AdwsClientAsync::EnumerationClient(
    "192.168.1.10", "DC01.corp.local", "CORP", "Administrator", "Passw0rd");

auto future = ac.QueryAsync("(objectClass=user)", {"sAMAccountName"});

// ... do other work while the query runs ...

auto users = future.get();  // blocks until complete; re-throws any exception

慢速 DC 超时：```cpp if (future.wait_for(std::chrono::seconds(5)) == std::future_status::timeout) { // query is still running }

所有操作都有异步变体： `QueryAsync`, `EnumerateAsync`, `GetAsync`, `PutAsync`, `DeleteAsync`, `CreateAsync`, `MoveAsync`。

### 连接池 （高频率 / 多线程工作负载）```cpp
#include "bridgehead/adws/AdwsClientPool.hpp"

// Enumeration pool, Query / Enumerate
bridgehead::adws::AdwsClientPool pool({
    .host = "192.168.1.10", .fqdn = "DC01.corp.local",
    .domain = "CORP", .username = "Administrator", .password = "Passw0rd",
    .maxSize = 4,   // up to 4 concurrent authenticated sessions
});

auto users = pool.Query("(objectClass=user)", {"sAMAccountName"});

// Resource pool, Get / Put / Delete
bridgehead::adws::AdwsClientPool resPool({
    .host = "192.168.1.10", .fqdn = "DC01.corp.local",
    .domain = "CORP", .username = "Administrator", .password = "Passw0rd",
    .maxSize = 4,
    .endpoint = bridgehead::adws::PoolEndpoint::Resource,
});
auto obj = resPool.Get("CN=Alice,OU=Users,DC=corp,DC=local", {"mail"});
resPool.Put("CN=Alice,OU=Users,DC=corp,DC=local", {{"mail", {"[email protected]"}}});

// ResourceFactory pool, Create
bridgehead::adws::AdwsClientPool rfPool({
    .host = "192.168.1.10", .fqdn = "DC01.corp.local",
    .domain = "CORP", .username = "Administrator", .password = "Passw0rd",
    .endpoint = bridgehead::adws::PoolEndpoint::ResourceFactory,
});
rfPool.Create("CN=NewUser,OU=Users,DC=corp,DC=local", "user",
              {{"sAMAccountName", {"newuser"}}});
