logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT
or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes
the auth module interface to 2 (from 1). The effect of this is
that clients can access resources as a machine account if they
set these flags. This is the same as Windows (think of a VPN
where the vpn client authenticates itself to a VPN server
using machine account credentials - the vpn server checks
that the machine password was valid by performing a machine
account check with the PDC in the same was as it would a
user account check. I may add in a restriction (parameter)
to allow this behaviour to be turned off (as it was previously).
That may be on by default.
Andrew Bartlett please review this change carefully.

* \PIPE\unixinfo
* winbindd's {group,alias}membership new functions
* winbindd's lookupsids() functionality
* swat (trunk changes to be reverted as per discussion with Deryck)
...hmmm... completely bogus. This does not affect us as a domain controller,
as we never set other_sids, but I have *no* idea how winbind got away with it.
Please review thoroughly, samba4 idl looks closer to reality here.
Test case: Member of w2k3 domain, authenticate as a user who is member of one
or more domain local groups. Easiest review with 'client schannel = no'.
Thanks,

The old #ifdef JRATEST-block was copying 16 bytes and thus overwriting
acct_flags with bizarre values, breaking a lot of things.
This patch is successfully running in a production environment for quite
some time now and is required to finally allow Exchange 5.5 to access
another Exchange Server when both are running on NT4 in a
samba-controlled domain. This also allows Exchange Replication to take
place, Exchange Administrator to access other Servers in the network,
etc. Fixes Bugzilla #1136.
Thanks abartlet for helping me with that one.

for setting up an schannel connection. This solves the problem
of a Samba DC running winbind, trusting a native mode AD domain,
and needing to enumerate AD users via wbinfo -u.
NTLM Authentication:
- Add a 'privileged' mode to Winbindd. This is achieved by means of a directory
under lockdir, that the admin can change the group access for.
- This mode is now required to access with 'CRAP' authentication feature.
- This *will* break the current SQUID helper, so I've fixed up our ntlm_auth
replacement:
- Update our NTLMSSP code to cope with 'datagram' mode, where we don't get a
challenge.
- Use this to make our ntlm_auth utility suitable for use in current Squid 2.5
servers.
- Tested - works for Win2k clients, but not Win9X at present. NTLMSSP updates
are needed.
- Now uses fgets(), not x_fgets() to cope with Squid environment (I think
somthing to do with non-blocking stdin).
- Add much more robust connection code to wb_common.c - it will not connect to
a server of a different protocol version, and it will automatically try and
reconnect to the 'privileged' pipe if possible.
- This could help with 'privileged' idmap operations etc in future.
- Add a generic HEX encode routine to util_str.c,
- fix a small line of dodgy C in StrnCpy_fn()
- Correctly pull our 'session key' out of the info3 from th the DC. This is
used in both the auth code, and in for export over the winbind pipe to
ntlm_auth.
- Given the user's challenge/response and access to the privileged pipe,
allow external access to the 'session key'. To be used for MSCHAPv2
integration.

Probably Veritas too... :-).
It allows Samba as a domain member to authenticate against an AS/U server such
as the older HP PDC product or PD Netlink. It does this by trying a netlogon
with info level 3 and then falling back to info level 2 if the PDC returns
invalid info level.
Jeremy.
jeremy, the intent is to call se_access_check() with usr-sid, grp-sid,
array-of-group-rids (but array-of-group-sids would do).
please do look at smbd/lanman.c's api_NetWkstaGetInfo, it will show you
that we really do need to store the entire NET_USER_INFO_3 structure.
then again, api_NetWkstaGetInfo is only used by win9x so who cares :)
* Added SEC_CHAN_BDC
* Fix for endianness problem reported by Edan Idzerda <edan@mtu.edu>. A
BUFFER2 is really a "unibuf" in my terminology and we should treat it as
such.
* Added some more common NT structures (BIGINT, BUFHDR2, BUFFER4).
* Added NET_SAM_SYNC (-> NetDatabaseSync2) RPC for account replication.
Still experimental and incomplete, with a few too many NULL security
descriptors lying around (must go look at Jeremy's SD code). Haven't
worked out password encryption yet either.
However, the XXX_INFO structures I've added to rpc_netlogon.h are quite
nice as they give some insight into how these objects are stored in the
SAM.
WARNING - so far this has only been tested against a Samba PDC
(still waiting for IS to add me the machine accounts :-).
Still missing is the code in smbpasswd that will add a machine
account password and change it on the domain controller, but
this is not hard, and I will check it in soon.

all I saw" - the book of Jeremy, chapter 1 :-).
So here is the mega-merge of the NTDOM branch server code.
It doesn't include the new client side pieces, we'll look
at that later.
This should give the same functionality, server wise, as
the NTDOM branch does, only merged into the main branch.
Any fixes to domain controler functionality should be
added to the main branch, not the NTDOM branch.
This code compiles without warnings on gcc2.8, but will
need further testing before we are sure all the working
functionality of the NTDOM server branch has been
correctly carried over.
I hereby declare the server side of the NTDOM branch
dead (and all who sail in her :-).
Jeremy.
