I can't point at specific problems right now, but that is
mainly because I have not yet seen larger environments with
AD. However, my recent experience with tuning the SMB and
cluster environment is that even a much older and more
widely used code basis (smbd) can hold really bad and hard
to overcome surprises. So I would really like to stand on
OpenLDAP's shoulders to see farther.
