Is ity possible that the status code is not the one from
the NtQueryInformationFile call but rather from the
NtCreateFile call before? In that case the first NT_SUCCESS (status)
is what fails.
A couple of lines above, line 2211ff, there's this:
/* No right to access EAs or EAs not supported? */
if (status == STATUS_ACCESS_DENIED || status == STATUS_EAS_NOT_SUPPORTED
/* Or a bug in Samba 3.2.x (x <= 7) when accessing a share's root dir
which has EAs enabled? */
|| status == STATUS_INVALID_PARAMETER)
{
no_ea = true;
/* If EAs are not supported, there's no sense to check them again
whith suffixes attached. So we set eabuf/easize to 0 here once. */
if (status == STATUS_EAS_NOT_SUPPORTED)
There are two places which check for STATUS_EAS_NOT_SUPPORTED.
If you check additionally for STATUS_NOT_SUPPORTED in both places,
does it work now?
