我已经在 Windows Server 2019 上设置了 Active Directory。我正在尝试使用 LDAP 从 Windows 客户端连接到 Active Directory。我已使用此代码,对 Microsoft 文档稍作修改:
// Verify that the user passed a hostname.
if (hostname!=NULL)
{
// Convert argv[] to a wchar_t*
size_t origsize = strlen(argv[1]) + 1;
size_t convertedChars = 0;
wchar_t wcstring[newsize];
mbstowcs_s(convertedChars, wcstring, origsize, argv[1], _TRUNCATE);
wcscat_s(wcstring, L" (wchar_t *)");
hostName = wcstring;
}
else
{
hostName = NULL;
}
// Initialize a session. LDAP_PORT is the default port, 389.
pLdapConnection = ldap_init(hostName, LDAP_PORT);
if (pLdapConnection == NULL)
{
// Set the HRESULT based on the Windows error code.
char hr = HRESULT_FROM_WIN32(GetLastError());
printf( "ldap_init failed with 0x%x.\n",hr);
goto error_exit;
}
else
printf("ldap_init succeeded \n");
// Set the version to 3.0 (default is 2.0).
returnCode = ldap_set_option(pLdapConnection,
LDAP_OPT_PROTOCOL_VERSION,
(void*)&version);
if(returnCode == LDAP_SUCCESS)
printf("ldap_set_option succeeded - version set to 3\n");
else
{
printf("SetOption Error:%0X\n", returnCode);
goto error_exit;
}
// Connect to the server.
connectSuccess = ldap_connect(pLdapConnection, NULL);
if(connectSuccess == LDAP_SUCCESS)
printf("ldap_connect succeeded \n");
else
{
printf("ldap_connect failed with 0x%x.\n",connectSuccess);
goto error_exit;
}
// Bind with current credentials (login credentials). Be
// aware that the password itself is never sent over the
// network, and encryption is not used.
printf("Binding ...\n");
returnCode = ldap_bind_s(pLdapConnection, NULL, NULL,
LDAP_AUTH_NEGOTIATE);
if (returnCode == LDAP_SUCCESS)
printf("The bind was successful");
else
goto error_exit;
// Normal cleanup and exit.
ldap_unbind(pLdapConnection);
return 0;
// On error cleanup and exit.
error_exit:
ldap_unbind(pLdapConnection);
return -1;
我是活动目录的新手,以前从未使用过 Windows 服务器。
如何在此 LDAP 查询中连接到 Active Directory?我是否在代码中的主机名中传递服务器名称或 Active Directory 域名?
此外,我收到服务器名称未解析错误。我应该在 Windows 服务器或本地局域网中使用 dns 服务来消除错误吗?
