Qt app and Active directory?

xopherira

I have a Qt app that I need to default the current users email. Is there a way in Qt to get the username from active directory in order to use as a default? Has anyone had experience with this?

This is platform dependant. What OS are you using?

xopherira

I am using windows 7 with Qt 5, minGw build kit.

You can use QSettings to register your program in the keys described here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd203067(v=vs.85).aspx

Not directly in via Qt. But maybe this helps.

You could try GetUserNameEx with NameUserPrincipal... not sure if AD populates that in your scenario, but worth a try?

There's no API for AD in Qt libraries, afaik. One way to achieve what you want though, is to call ldifde with QProcess and get the info from its output :)

Thanks to all, I will get one of these to work!

For those interested in my solution, here's the code.

   TCHAR Username[UNLEN+1];
    DWORD nULen = UNLEN;
    GetUserName(Username, &nULen);
    QString adUserName = QString::fromWCharArray(Username);

GetUserName

But what library did you use?

xopherira

#include <Security.h>
#include <lmcons.h>
#include <Windows.h>

Presumably he's referring to GetUserName, which is part of the Windows API (formerly known as "win32"). Obviously not portable, but that's presumably not an issue for @xopherira in this particular use case.

Cheers.
