0f51ae83f0 r11181: Implement wbinfo -s and wbinfo --user-sids. The patch is so large because
--user-sids required the extension to trusted domains.

Implement "winbind sealed pipes" parameter for debugging purposes.

d68319431e r11095: Implement wb_getuserdomgroups.
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

42ececdfae r11093: Implement wb_queue_domain_send: If the domain is not yet initialized, do that
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.

207a6bf397 r11068: Fix pam_auth_crap, remove the sync code. I don't know what it was when I
tested it, but I can not reproduce the problem I had with abartlett's initial
implementation anymore.

Fix a bug found using valgrind.

d617556ef5 r10878: Reply to some comments by tridge and metze:
* 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.

9e5d44d567 r10852: Continuation-based programming can become a bit spaghetti...
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.

e0c11738ae r10834: Work in progress on winbind. With some helper routines the composite functions
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?

012893cb42 r10691: This gets half-way to wbinfo -n. It acquires an lsa pipe, and does a
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.

e5c6a3e361 r10683: Samba3's wbinfo -t should give the correct answer now.
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.

ab4d635b92 r10504: - seperate implementation specific stuff, from the generic composite
stuff.
- don't use SMBCLI_REQUEST_* state's in the genreic composite stuff
- move monitor_fn to libnet.

NOTE: I have maybe found some bugs, in code that is dirrectly in DONE or ERROR
      state in the _send() function. I haven't fixed this bugs in this
      commit! We may need some composite_trigger_*() functions or so.
      And maybe some other generic helper functions...

9593101ec1 r10491: First step towards wbinfo -t: This issues a name request for the primary
domain and gets the DC's name via a mailslot call.

Metze, I renamed wbsrv_queue_reply to wbsrv_send_reply in accordance with
irpc_send_reply. Having _queue_ here and _send_ there is a bit confusing. And
as everything is async anyway, the semantics should not be too much of a
problem.
