urrr... yes, and it goes through some processing and you get an snum and
that gets a connection_rec to represent the service.

i know.  it's just... not as simple as we would like, just thought i'd
point out what i think the discrepancy is.

if you manage to do that, i'll be impressed!

i have _some_ of the info associated with the actual handle, already, via
some of the struct cli_connection code.  have a look at
rpc_client/cli_connect.c.

for example, i have code that passes over a usr_sess_key which actually
comes from smbd over the MSRPC-loopback, but it originally came from
netlogond!!!  please don't ask me what contortions i had to go through to
get this.

_anyway_, check become_vuser() and how it's set up, and how the info is
stored.

to cut a long story short, i don't recommend you try and create a
connection_struct, but let's try and think up some alternative, simpler
scheme.

i tried really hard to cut connection_struct and as much smbd code away
from the msrpc daemons as much as possible.

or something similar, yes.

yep!

you know we're becoming NT-advocates, you and me, both.

we're going to have to be careful!
