On that basis, I have prepared the attached patches. Currently, having
an endpoint mapper implementation causes ncalrpc pipes and TCP sockets
to be created for embedded services, but as you say, this isn't going to
work.
If we want to make any of these services support ncalrpc and TCP, we
will need to move them to a child, like lsasd.
What do you think?
