We certainly could. I should have been clearer as to why I suggested
this particular task: Yes, NTLM authentication could be done with an
existing or modified interface, and the other calls in winbind.idl are
I suggested this task because all the other parts are already in place:
We have a simple client to test with (ntlm_auth4), and the server code
already exists. That way, the task itself is fairly simple - just glue
already working components together.
That said, there are only 3 working calls in winbind.idl, and we could
certainly continue to expand the existing protocol. My only comment on
that is that it just puts off at least trying to use IRPC (which is
already based on metze's binding handle work), and a common unix domain
socket based messaging system, both of which would I think be useful
IRPC is used elsewhere in the source4 code. It is quite a flexible,
async, IDL-based messaging system, and it would be great if more parts
of our code could talk to each other.
