That test is almost as bad as it can ever get.  Given that enumerating 
all AD accouts with mkpasswd takes about 2 hours and I'm doing something 
very similar here, I'm not even surprised.  I was more surprised to see 
the server go so fast, but my guess is that it can use jumbo frames to 
talk to the AD.

No, sorry.

If you really want fast but incorrect there's always the "noacl" mount 
option.
