Clearly winbindd in Samba4 has not ever been run against windows, as
when we fixed the Samba4 server not to cause XP to loop like this,
Samba4's own client starts looping...

The problem was that we would do a blocking wait for the LDAP server,
which was also blocking on us returning (because we were in single
process mode).
The LDAP connection being made here is useless anyway, and will need
to be an async ldb_connect() before anybody reintroucues it (nobody in
their right mind would program a winbindd backend on pure LDAP, when
the ldb abstraction is available).

We need to intialise *ids regardless of the status of the call, as the
IDL specifies that the out[] array always exists. If we don't
initialise out then we get a segv when a id mapping fails.
This still doesn't explain why the idmapping is failing, but at least
the client now gets NT_STATUS_NONE_MAPPED rather than a crashed
server.

We now setup a libnet_ctx for each domain. We should then be able to

Add a test for wbinfo -a to test_member.sh
Reimplement the server-side 'pam_auth' and 'pam_auth_crap' calls to
use the same SamLogon code as auth_winbind uses.
In my previous code, we did not bind to the LSA and SAMR pipes, before
attempting operations. We now do this (how we passed any tests before
is beyond me).
This required some rework, particularly to make it easier to setup
secondary connections. The new rpc_secondary_auth_connection()
function also performs the bind.
The dcerpc_connect.c file was getting to big, so things have been
merged into dcerpc_secondary.c.

decided to clean it up a little.
We now use SPNEGO for authentication if possible, and common routines
shared with the rest of the librpc codebase. Rather than make a
connection to IPC$, then connect the pipes to it, we instead have the
lsa and samr pipes as 'secondary connections'.

using the pattern in the clilsa code, it didn't fill in the p->binding

This commit cleans up a number of aspects of the LSA interface.
Firstly, we do 2 simple searches on opening the LSA policy, to obtain
the basic information we need. This also avoids us searching for
dnsDomain (an invented attribute).
While I was at it, I added and tested new LSA calls, including the
enumTrustedDomainsEx call. I have also merged the identical structures
lsa_DomainInformation and lsa_DomainList.
Also in this commit: Fix netlogon use of uninitialised variables.

in Samba4. This allows us to start winbindd by default, including in
'make test'.
This is via a new 'winbindd socket directory' parameter for utilities
linked against loadparm, as well as a --with-winbindd-socket-dir
option to configure (setting the default and the value for simple
clients).
I hope to add basic winbindd tests, to ensure continued correct
operation, but at least now I don't have to manually change my 'server
services' line.
The other problem with the hard-coded /tmp/.winbind is that RedHat has
moved this in Fedora (to /var/run I think). For this reason, this
functionality should probably be ported to Samba3 as well.
The default for Samba4 is PREFIX/var/run/winbind_pipe.
I have also re-added the paranoia checks from Samba3 for correct
permissions on the socket directory.
Andrew Bartlett
(This used to be commit 8866aa06ff)
multiple protocols, replacing it with the packet handling subsystem.
We don't have multiple protocols at present, and the abstraction layer
only serves to confuse matters. Also, the new packet subsystem removes
the need to handle partial reads.
We can easily add new protocols from the socket up instead, becaue the
difficult bits are done by the packet layer.

In librpc, always try SMB level authentication, even if trying
schannel, but allow fallback to anonymous. This should better
function with servers that set restrict anonymous.
There are too many parts of Samba that get, parse and modify the
binding parameters. Avoid the extra work, and add a binding element
to the struct dcerpc_pipe
The libnet vampire code has been refactored, to reduce extra layers
and to better conform with the standard argument pattern. Also, take
advantage of the new libnet_Lookup code, so we don't require the silly
'password server' smb.conf parameter.
To better support forcing traffic to be sealed for the vampire
operation, the dcerpc_bind_auth() function now takes an auth level
parameter.
Andrew Bartlett
(This used to be commit d65b354959)
dcerpc_interface_table struct rather then a tuple of interface
name, UUID and version.
This removes the requirement for having a global list of DCE/RPC interfaces,
except for these parts of the code that use that list explicitly
(ndrdump and the scanner torture test).
This should also allow us to remove the hack that put the authservice parameter
in the dcerpc_binding struct as it can now be read directly from
dcerpc_interface_table.
I will now modify some of these functions to take a dcerpc_syntax_id
structure rather then a full dcerpc_interface_table.

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,

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.

Volker
(This used to be commit deb127e04e)
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

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 2a6b805385)
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.

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.
Volker
(This used to be commit e38e50127a)
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.

- 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...

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.
