Sadly not at this stage.  You can get more detail as you turn up the
debug level, but not a clear picture of all the details you need.  I
hope to address this soon - I've had requests for this from a couple of
clients recently so hopefully Samba 4.7 will finally have decent
logging here.

I hope this helps a little,
