Ok, can you try this patch against 3.3.1 ? It might change
client behavior, as at the moment we return NT_STATUS_ACCESS_DENIED
when a client asks for SEC_FLAG_SYSTEM_SECURITY access to a file
(which is a request to get at the system security audit ACL).

The patch changes our behavior to return an error of NT_STATUS_PRIVILEGE_NOT_HELD
instead, which may then cause the client to fallback to asking
for less privileges on the open (thus allowing it to succeed).
