At least in some configurations, I see NETLOGON requests from multiple clients being served from the same PID and process.
4.5.0 doesn't have the multiprocess netlogon patches or am I missing something?
This was noticed in master for 4.7, they were introduced with 4.6. The mechanism is clearly a little too subtle, we probably need to make it fail if 'uses handles' and 'does not use handles' is combined on the same NP or TCP/IP endpoint.
