[Bug 9353] New: CreateFile with OPEN_ALWAYS on an existing directory sets wrong error code

http://bugs.winehq.org/show_bug.cgi?id=9353

Summary: CreateFile with OPEN_ALWAYS on an existing directory
                    sets wrong error code
           Product: Wine
           Version: 0.9.43.
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-kernel
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When I call CreateFile like this:
CreateFile("testdir", GENERIC_READ|GENERIC_WRITE, 0, NULL, OPEN_ALWAYS,
FILE_ATTRIBUTE_NORMAL|FILE_FLAG_BACKUP_SEMANTICS, NULL);
with the directory "testdir" existing, it sets ERROR_ACCESS_DENIED, while
Windows XP SP 2 sets ERROR_ALREADY_EXISTS (didn't confirm the Windows side
myself).
The correct flag I should be passing instead of OPEN_ALWAYS is OPEN_EXISTING
(which works on Windows XP as well).
> From a first try to find the cause for this, I believe that it is not in

CreateFile and neither in NtCreateFile, but somewhere in wineserver.
