This also removes dcerpc_bind_auth_password, the only user of
dcerpc_bind_auth. And this was not only passwords anyway.
Andrew Bartlett, as usual: Please take a close look.
Thanks,

that some values aren't handled. The remaining warnings I think are
actual bugs or required functionality that is missing (mostly lack of
server side Unix extensions).

support cldap and other stuff in the future.
This temporarily disables wbinfo -t, but that will come back soon.
Try an ldap bind using gss-spnego. This got me krb5 binds against "our" w2k3
and a trusted w2k, although with some memleaks from krb5 and a BAD_OPTION
tgs-rep error.

minimal comments much better (much like volker scans code of less than
80 cols better ;-)

logins (changing the winbindd interface).
Clean up the wbsrv_samba3_async_epilogue() handling, as it was mixing
auth and other replies, such that all replies were having the auth
error strings set. We now do a better job of filling in the right
errors in the right places.

Tridge, if you have the time, you might want to look at a problem I'm having
with unix domain stream sockets. From a comment in this commit:
/* Using composite_trigger_error here causes problems with the client
* socket. Linux 2.6.8 gives me a ECONNRESET on the next read after
* writing the reply when I don't wait the 100 milliseconds. */
This is in winbind/wb_cmd_userdomgroups.c:93.
The problem I have is that I can not *immediately* send an error reply to the
client because the next receive fails. Waiting 100 milliseconds helps. It
might also be a problem with epoll(), I don't really know.
I'd appreciate if you took a brief look at this, maybe I'm doing something
wrong.
Thanks,
Volker

first. And if a request is being processed, queue it. This correctly survived
3 endless loops with wbinfo's doing different things while starting up smbd.
The number of indirections starts to become a bit scary, but what can you do
without a decent programming language that provides closures :-)
One thing that we might consider is to auto-generate async rpc requests that
return composite_context structs instead of rpc_requests. Otherwise I'd have
to write a lot of wrappers like composite_netr_LogonSamLogon_send.
The alternative would be to write two versions of wb_queue_domain_send which I
would like to avoid. This is cluttered enough already.

implementation anymore.
Fix a bug found using valgrind.

but the version before did not either, so we're not worse than before.
One thing this does better is to call the domain init code if it's not there
yet.

* rename the composite helper functions from comp_* to composite_*
* Move the lsa initialization to wb_connect_lsa.c
* Equip smb_composite_connect with a fallback_to_anonymous
The latter two simplify wb_init_domain.c quite a bit.

Initialize a domain structure properly. Excerpt from wb_init_domain.c:
/*
* Initialize a domain:
*
* - With schannel credentials, try to open the SMB connection with the machine
* creds. Fall back to anonymous.
*
* - If we have schannel creds, do the auth2 and open the schannel'ed netlogon
* pipe.
*
* - Open LSA. If we have machine creds, try to open with ntlmssp. Fall back
* to schannel and then to anon bind.
*
* - With queryinfopolicy, verify that we're talking to the right domain
*
* A bit complex, but with all the combinations I think it's the best we can
* get. NT4, W2k3SP1 and W2k all have different combinations, but in the end we
* have a signed&sealed lsa connection on all of them.
*
* Is this overkill? In particular the authenticated SMB connection seems a
* bit overkill, given that we do schannel for netlogon and ntlmssp for
* lsa later on w2k3, the others don't do this anyway.
*/
Thanks to Jeremy for his detective work, and to the Samba4 team for providing
such a great infrastructure.
Next step is to connect to SAM. Do it via LDAP if we can, fall back to samr
with all we have.

Plaintext should be simple, but I'm going to do some infrustructure
work first.

Abartlet, now I think I need some assistance to implement the pam auth & crap
auth calls.

start to look sane.
Question: What about providing all winbind commands as irpc interfaces that
are called from the samba3 compatibility layer? This way it would be easy for
other samba components to access its functionality. Does that make sense?
Volker
(This used to be commit 2a6b8053859ea5690f90a8d2074d2bb4f06551f8)
queryinfopolicy. Idea is to get a consistency check between that and our
notion of the domain name and sid, and take the lsa pipe as the holder of the
central smbcli_tree that netlogon and samr use as well.
Volker

for it pending.
Also fix a bug with timed events: Don't call the same event recursively in the
handler's inner semi-async event loop.

Tridge, if you have time, you might want to look at the segfault I was still
seeing. Now I store the handle to the netlogon pipe in the global winbind
state and free it on the next entry into check_machacc. The problem seems to
be that talloc_free()ing a pipe struct from within a callback function on that
pipe is not possible. I think I can live with that, but it has been not really
obvious. To reproduce the segfault you might want to look at putting a
talloc_free(state->getcreds->out.netlogon) into
wbsrv_samba3_check_machacc_receive_creds. This is called from a dcerpc
callback function.
In particular if the check failed it would be nice if I could delete the pipe
directly and not post a different event to some winbind queue.
I tried to delete the pipe from a timed event triggered immediately, but this
also fails because the inner loop seems to hit the same event again, calling
it twice.
