Replacing GINA

[Anders Molin]

I'm working on a GINA replacement, because we need to do some custom log on of the users. I have one major problem that I can't find any solutions for. When the user is logged on, the start-menu is, err..., not exactly disabled but it's acting very strage. Fucus is not folloving the mouse, and it don't respond to mouse clicks. Anyone got an idea? I have been searching google and found other people with the same problem, but not any solutions. :( - Anders Money talks, but all mine ever says is "Goodbye!"

Are you sure you setup proper security descriptors for the WinSta0 and WinSta0/Default windowstation/desktop objects? Seems that the user account the shell process is running under has not the proper access rights to create menus. -- Daniel Lohmann http://www.losoft.de (Hey, this page is worth looking! You can find some free and handy NT tools there :-D )

I found this a couple of hours ago, and it did the trick :)

TOKEN\_GROUPS \*pGroups;
DWORD dwSize, i;
BOOL status = FALSE;

pGroups = (\_TOKEN\_GROUPS\*)LocalAlloc(LMEM\_FIXED, 2048);
GetTokenInformation(pgContext->UserToken, TokenGroups, pGroups, 2048, &dwSize);

for (i = 0; i < pGroups->GroupCount; i++)
{
	if ((pGroups->Groups\[i\].Attributes & SE\_GROUP\_LOGON\_ID) == SE\_GROUP\_LOGON\_ID)
	{
		CopySid(GetLengthSid(pLogonSid), pLogonSid, pGroups->Groups\[i\].Sid );
		break;
	}
}
LocalFree(pGroups);
