LDAP 获取完整的用户名 C++

Question

我正在办公室写一个小应用程序。 在此应用程序中，我必须获取完整的用户名。 它是用 Qt / C++ 编写的

我喜欢通过 LDAP 获取此信息。 现在我可以连接到我们的 Active Directory 服务器并可以连接到搜索功能。

此信息来自 Microsoft 编写的示例。

但是在这一点上，示例使我感到困惑。 我不明白如何给这个服务器一个用户名并接收全名。

微软示例链接：http://msdn.microsoft.com/en-us/library/windows/desktop/aa367016(v=vs.85).aspx

谁能给我一个建议，我怎样才能得到这些信息？

感谢并致以最诚挚的问候 克里斯;)

附：对不起英语不好。 P.S.S，如果我错过了什么或者您需要更多信息，请说出来。

Answer 1

您似乎在请求cn 或commonName，有时该属性的值是全名。如果不是，请尝试将givenName 和sn 添加到请求的属性列表中。 givenName 是名字 sn 是 surname 或姓氏。

Answer 2

还有一点其他问题。 下面你会看到得到我需要的东西的线条。 这听起来有点愚蠢，但是当我运行代码时，pMyAttributes[0] 中的属性将永远不会显示。 我不在乎，因为我不需要这些信息，但它似乎是正确的。 我有点害怕我以后会得到错误的信息，我的程序会得到错误。

使用“PWCHAR pMyAttributes[4];”设置过滤器什么都不显示

但设置过滤器“PWCHAR pMyAttributes[5];”就像那样，我得到了我想要的一切。 有人可以解释一下吗？

PWCHAR pMyAttributes[4];
ULONG errorCode = LDAP_SUCCESS;

pMyAttributes[0] = (WCHAR*)QString("sn").utf16();
pMyAttributes[1] = (WCHAR*)QString("mailNickname").utf16();
pMyAttributes[2] = (WCHAR*)QString("cn").utf16();
pMyAttributes[3] = NULL;
