我正在编写一个远程连接到服务器的客户端应用程序。我需要模拟我的客户将与之合作的用户。
这是我的代码的摘录:
COAUTHIDENTITY coAuthIdentity, *pCoAuthIdentity;
COAUTHINFO coAuthInfo;
CComBSTR bstrDomain(domain), bstrServer(server);
CComBSTR bstrUser(user), bstrPassword(password);
CComBSTR bstrServerPrincName(domain);
bstrServerPrincName.Append(L"\\");
bstrServerPrincName.Append(server);
coAuthIdentity.Flags = SEC_WINNT_AUTH_IDENTITY_UNICODE;
coAuthIdentity.Domain = (USHORT *)bstrDomain.m_str;
coAuthIdentity.DomainLength = bstrDomain.Length();
coAuthIdentity.Password = (USHORT *)bstrPassword.m_str;
coAuthIdentity.PasswordLength = bstrPassword.Length();
coAuthIdentity.User = (USHORT *)bstrUser.m_str;
coAuthIdentity.UserLength = bstrUser.Length();
pCoAuthIdentity = &coAuthIdentity;
*ppCoAuthIdentity = pCoAuthIdentity;
coAuthInfo.dwAuthnSvc = RPC_C_AUTHN_DEFAULT; // Have COM negotiate the best authentication service
coAuthInfo.dwAuthzSvc = RPC_C_AUTHZ_NONE;
coAuthInfo.pwszServerPrincName = bstrServerPrincName;
coAuthInfo.dwAuthnLevel = RPC_C_AUTHN_LEVEL_DEFAULT;
coAuthInfo.dwImpersonationLevel = RPC_C_IMP_LEVEL_IMPERSONATE;
coAuthInfo.pAuthIdentityData = &coAuthIdentity;
coAuthInfo.dwCapabilities = EOAC_NONE;
COSERVERINFO coServerInfo;
::memset(&coServerInfo, 0, sizeof(COSERVERINFO));
coServerInfo.pwszName = bstrServer;
coServerInfo.dwReserved1 = 0;
coServerInfo.pAuthInfo = &coAuthInfo;
coServerInfo.dwReserved2 = 0;
MULTI_QI multiQI = { &__uuidof(IServer), 0, 0 };
TCHAR name [MAX_COMPUTERNAME_LENGTH + 1];
DWORD size = sizeof(name);
DWORD dwServer = CLSCTX_SERVER;
if (::GetComputerName(name, &size) != 0)
{
if (_wcsicmp(name, coServerInfo.pwszName))
dwServer = CLSCTX_REMOTE_SERVER;
else
dwServer = CLSCTX_LOCAL_SERVER;
}
else
{
DWORD dwError = GetLastError();
return HRESULT_FROM_WIN32(dwError);
}
hr = CoCreateInstanceEx(
__uuidof(IServer),
NULL,
dwServer,
&coServerInfo,
1,
&multiQI);
当我将客户端和服务器安装在同一台计算机上时,就会出现我的问题。在 Windows 2003 中,当我将任何用户(有效或无效)的凭据传递到我的服务器时,CoCreateInstanceEx 函数总是返回 S_OK。
问题是在服务器端使用的用户不是模拟用户,而是启动我的客户端进程的用户。
使用 Windows 2008 可以正常工作。有任何想法吗?
提前致谢。
