I've looked at the discussion on cifs-protocol, and it seems we may need
to ensure that the LSA operations are protected directly not just by
virtue of the DS ACLs that may apply to LDAP operations.
That is, we currently assume in much of our SAMR and LSA server that the
DS layer will do the right access control. We already know that this
isn't strictly true, and we should consider if we have to do more access
control at the LSA level.
On your new patch, I was reviewing it with tridge, and I think this
additional patch may improve performance and help others understand the
subtle interaction here. I also attach another tidy-up for your review.
