This is actually a "feature" of HTTP, and therefore WebDAV. HTTP has no
concept of "state"; every operation is a single action in and of itself.
There are all sorts of ways to emulate statefulness (cookies, etc.) but
it's all just a workaround.
I suspect this isn't as much of a bottleneck as you think. I would
imagine winbind is doing its own caching so it's not actually going to
your ADS for each and every request. Have you tried benchmarking the
same action without any authentication to see if there's any noticeable
difference?
