Reload certificates with the command 'smbcontrol ldap_server reload-certs'.
The message is send to the master process, who forwards it to the workers
processes.
The master process reload and, if necessary, create the certificates first,
then the workers processes reload them.

If a client disconnected all its interfaces and reconnects when
the come back, it will likely start from any ip address returned
dns, which means it can try to connect to a different ctdb node.
The old node may not have noticed the disconnect and still holds
the client_guid based smbd.
Up unil now the new node returned NT_STATUS_NOT_SUPPORTED to
the SMB2 Negotiate request, as messaging_send_iov[_from]() will
return -1/ENOSYS if a file descriptor os passed to a process on
a different node.
Now we tell the other node to teardown all client connections
belonging to the client-guid.
Note that this is not authenticated, but if an attacker can
capture the client-guid, he can also inject TCP resets anyway,
to get the same effect.

This is a separate binary executed from start_background_queue(). As
such it does not really gain much, but the idea is to move all the
code this runs out of the smbd and spoolssd binaries to just link
here.

We need a full request/response pair in order to avoid races in
the multichannel connection passing.
smb2srv_client_mc_negprot_send/recv locks the
db record for the given client_guid.
If there's no entry found, we add ourself and
return NT_STATUS_OK.
If there's an existing process for that client guid
we start messaging_filtered_read_send()
dbwrap_watched_watch_send() before calling
smb2srv_client_connection_pass().
Then we release the lock and wait for either
MSG_SMBXSRV_CONNECTION_PASSED to arrive or
retry if dbwrap_watched_watch_recv signaled
a change in the database.
If we got MSG_SMBXSRV_CONNECTION_PASSED we'll
return NT_STATUS_MESSAGE_RETRIEVED in order to
signal that the other process will take care of
the connection and we terminate the current process.
All that is done completely async, which means that
the IDLE_CLOSED_TIMEOUT (60 seconds) may trigger
deadtime_fn(), which will send itself a MSG_SHUTDOWN.
So the process that accepted the tcp connection
exists if there was no MSG_SMBXSRV_CONNECTION_PASSED
within 60 seconds.
However the fd may still exists in the kernel (and
the new connection may still be handed to the other
process. If that process somehow exists before
there's no way to prevent a connection termination
for the client.
