9dbf2e2419 r991: Allow winbindd to use the domain trust account password
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.

fcbfc7ad06 Changes all over the shop, but all towards:
- NTLM2 support in the server
 - KEY_EXCH support in the server
 - variable length session keys.

In detail:

 - NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).

 * This is known as 'NTLMv2 session security' *

(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes.  We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)

This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed.  This also needs to be turned off for
'security=server', which does not support this.

- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.

- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.

- There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure.  This should help the SPNEGO implementation.

- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.

- The other big change is to allow variable length session keys.  We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter.  However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.

 * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *

- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe.  This
should help reduce some of the 'it just doesn't work' issues.

- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer.  (just allocate)


REMEMBER to make clean after this commit - I have changed plenty of data structures...

d3b9384308 Fix for #480. Change the interface for init_unistr2 to not take a length

b42500299c Fix for bug #334. We don't unmarshall the trusted domain or secrets
info delta correctly and thus crash when doing a net rpc samdump.

The easiest thing at the moment it to comment out these functions as
they seriously don't correspond with reality (netmon/ethereal) and the
data in the containers aren't used anyway.

61116049ca This patch takes the work the jerry did for beta2, and generalises it:
- The 'not implmented' checks are now done by all auth modules
 - the ntdomain/trustdomain/winbind modules are more presise as to
   what domain names they can and cannot handle
 - The become_root() calls are now around the winbind pipe opening only,
   not the entire auth call
 - The unix username is kept seperate from the NT username, removing the
   need for 'clean off the domain\' in parse_net.c
 - All sid->uid translations are now validated with getpwuid() to put a very
   basic stop to logins with 'half deleted' accounts.

a31a2c159c well this was easy...
When winbindd is running on a PDC the SAM_ACCOUNT for a trusted user
has a username of DOMAIN\user.  Make sure to trim the domain part
from the username when filling in the net_sam_logon reply.
This fixes the browsing issues i was seen across domain trusts.

e0066d2dd4 again an intrusive patch:
- removed the ugly as hell sam_logon_in_ssb variable, I changed a bit the
definition of standard_sub_basic() to cope with that.

- removed the smb.conf: 'domain admin group' and 'domain guest group'
parameters ! We're not playing anymore with the user's group RIDs !

- in get_domain_user_groups(), if the user's gid is a group, put it first
in the group RID list.

I just have to write an HOWTO now ;-)

8ba00d147b OK. Smbpasswd -j is DEAD.
This moves the rest of the functionality into the 'net rpc join' code.

Futhermore, this moves that entire area over to the libsmb codebase, rather
than the crufty old rpc_client stuff.

I have also fixed up the smbpasswd -a -m bug in the process.

We also have a new 'net rpc changetrustpw' that can be called from a
cron-job to regularly change the trust account password, for sites
that run winbind but not smbd.

With a little more work, we can kill rpc_client from smbd entirly!
(It is mostly the domain auth stuff - which I can rework - and the
spoolss stuff that sombody else will need to look over).

b03e162127 samr_querydom_info level 1: found the meaning of the unknow fields. And
discovered that our reply is short by 4 bytes since day 1 of this code.

Added a decode function to rpcclient too.

splitted the STRING2 fields filling while trying to understand the win9x
userlist bug. (didn't fix the bug, but the reply looks closer to NT).

acb81fe408 Various post AuthRewrite cleanups, fixups and tidyups.
Zero out some of the plaintext passwords for paranoia

Fix up some of the other passdb backends with the change to *uid_t rather than
uid_t.

Make some of the code in srv_netlog_nt.c clearer, is passing an array around,
so pass its lenght in is definition, not as a seperate paramater.

Use sizeof() rather than magic numbers, it makes things easier to read.

Cope with a PAM authenticated user who is not in /etc/passwd - currently by
saying NO_SUCH_USER, but this can change in future.

60f0627afb This is a farily large patch (3300 lines) and reworks most of the AuthRewrite
code.

In particular this assists tpot in some of his work, becouse it provides the
connection between the authenticaion and the vuid generation.

Major Changes:
	- Fully malloc'ed structures.
	  - Massive rework of the code so that all structures are made and destroyed
	    using malloc and free, rather than hanging around on the stack.
	- SAM_ACCOUNT unix uids and gids are now pointers to the same, to allow them
	   to be declared 'invalid' without the chance that people might get ROOT by
	   default.

	- kill off some of the "DOMAIN\user" lookups.  These can be readded at a more
	  appropriate place (probably domain_client_validate.c) in the future. They
	  don't belong in session setups.

	- Massive introduction of DATA_BLOB structures, particularly for passwords.

	- Use NTLMSSP flags to tell the backend what its getting, rather than magic
	  lenghths.

	- Fix winbind back up again, but tpot is redoing this soon anyway.

	- Abstract much of the work in srv_netlog_nt back into auth helper functions.

This is a LARGE change, and any assistance is testing it is appriciated.

Domain logons are still broken (as far as I can tell) but other functionality
seems
intact.

Needs testing with a wide variety of MS clients.

d9d7f023d8 This commit is number 4 of 4.
In particular this commit focuses on:

Actually adding the 'const' to the passdb interface, and the flow-on changes.

Also kill off the 'disp_info' stuff, as its no longer used.

While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.

----

These changes introduces a large dose of 'const' to the Samba tree.
There are a number of good reasons to do this:

	- I want to allow the SAM_ACCOUNT structure to move from wasteful
	pstrings and fstrings to  allocated strings.  We can't do that if
	people are modifying these outputs, as they may well make
	assumptions about getting pstrings and fstrings

	- I want --with-pam_smbpass to compile with a slightly sane
	volume of warnings, currently its  pretty bad, even in 2.2
	where is compiles at all.

	- Tridge assures me that he no longer opposes 'const religion'
	based on the ability to  #define const the problem away.

	- Changed Get_Pwnam(x,y) into two variants (so that the const
	parameter can work correctly): - Get_Pwnam(const x) and
	Get_Pwnam_Modify(x).

	- Reworked smbd/chgpasswd.c to work with these mods, passing
	around a 'struct passwd' rather  than the modified username

---

This finishes this line of commits off, your tree should now compile again :-)

d5c9172ada Merge of sam sync code from TNG.
Reverse-engineered the sam replication protocol from staring at hex dumps
for a while.  It's pretty similar to the sam sync protocol with a couple of
different delta header types.

I wasn't able to figure out the format of the privilege stuff - needs more
time and a whiteboard.  (-:

The impressive bit is that the sam sync stuff from tng basically just
worked thanks mainly to Luke Leighton's efforts in this area.
