7b830350eb Mainly BDC-related changes.
* Added SEC_CHAN_BDC
* Propagate sec_chan into the various functions which change trust account
  passwords, so they can be used for domain control and inter-domain
  trusts.
* 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.

2e58ed7424 SAM database "set user info".
----------------------------

- removed DOM_RID4

- removed SAMR_UNKNOWN_32

- added SAMR_SET_USERINFO (opcode 0x32)

- added level 0x1 to SAMR_QUERY_DOM_INFO (needed for create user)

- fixed pwdb_gethexpwd() it was failing on XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

- added mod_sam21pwd_entry()

- preparing to call mod_sam21pwd_entry()

- added "user session key" to user_struct.dc.  this is md4(nt#) and is
  needed to decode user's clear-text passwords in SAMR_SET_USERINFO.

- split code out in chgpasswd.c to decode 516 byte password buffers.

73730f6004 Another UNICODE issue - this time BUFFER2 was being transmitted incorrectly. -
Matthew Chapman
365fa3b5fb Adding LSA_OPENSECRET (-> LsarOpenSecret) and LSA_QUERYSECRET
(-> LsarQuerySecret) on client side, including rpcclient command
"querysecret" for others to play with.

The major obstacle is working out the encryption algorithm used
for the secret value. It definitely uses the NT hash as part of the
key, and it seems the block size is 64 bits - probably DES based -
but I can't work out what's done in between. Help required.

65b0abe8b7 new "domtrust" test command. r&d into inter-domain trust accounts. -

ce24191939 Always null-terminate strings.
Also some string length and sizeof(pointer) corrections.

Matthew Chapman
a1d39af1ce UNICODE cleanup (see lib/util_unistr.c).
No more ugly static library buffers and all functions take a destination
string length (especially unistrcpy was rather dangerous; we were only
saved by the fact that datagrams are limited in size).

ac72fe1ab3 removal of the use of unistrn2 function: replace it with unistr2_to_str
which is more appropriate.

b8175702ef - lib/unix_sec_ctxt.c
attempt at taking lib/uid.c and getting a unix security context
	change module that is independent of "cnums" and "snums".
	a security context is needed for pipes, not just IPC$ or other
	services.

- group database API

	added add_group/alias_member, del_group/alias_member,
	del_group/alias_entry functions.  del_builtin_entry() is
	deliberately set to NULL to cause an exception, you cannot
	delete builtin aliases.

- parse_lsa.c srv_lsa.c

	fixed lookup_names code, it was a load of trash and didn't do
	anything.

- cmd_samr.c rpcclient.c srv_samr.c

	added "deletegroup", "deletealias", "delaliasmem", "delgroupmem",
	"addgroupmem", "addaliasmem", "createalias", "creategroup", to
	both client and server code.

	server code calls into unix stubs right now, which don't actually
	do anything.  the only instance where they are expected to do
	anything is in appliance mode NOT even in the ldap code or anything.

	client code modified to call samr_lookup_names() for group code
	(because we can) and lsa_lookup_names() for alias code (because
	we have to).

- srv_lookup.c

	oops, lookup on unsplit name, we got lookup on DOMAIN, DOMAIN\name
	instead of DOMAIN, name.
-
Luke Leighton
78a86c6496 added rid and sid_name_use to DOMAIN_GRP_MEMBER, for use in group member
query.

domain groups now work, hurrah!  only thing is that the description is
one character long, don't know why (which is wierd in itself).
-
Luke Leighton
9337049dfc adding group member code, made a start. found that the group members'
rid is needed not the name (see DOMAIN_GRP_MEMBER) decided to go home.

5d5d7e4de7 weekend work. user / group database API.
- split sam_passwd and smb_passwd into separate higher-order function tables

- renamed struct smb_passwd's "smb_user" to "unix_user".  added "nt_user"
plus user_rid, and added a "wrap" function in both sam_passwd and smb_passwd
password databases to fill in the blank entries that are not obtained
from whatever password database API instance is being used.

NOTE: whenever a struct smb_passwd or struct sam_passwd is used, it MUST
be initialised with pwdb_sam_init() or pwd_smb_init(), see chgpasswd.c
for the only example outside of the password database APIs i could find.

- added query_useraliases code to rpcclient.

- dealt with some nasty interdependencies involving non-smbd programs
and the password database API.  this is still not satisfactorily
resolved completelely, but it's the best i can do for now.

- #ifdef'd out some password database options so that people don't
mistakenly set them unless they recompile to _use_ those options.

lots of debugging done, it's still not finished.  the unix/NT uid/gid
and user-rid/group-rid issues are better, but not perfect.  the "BUILTIN"
domain is still missing: users cannot be added to "BUILTIN" groups yet,
as we only have an "alias" db API and a "group" db API but not "builtin-alias"
db API...

161eb6f511 amazing. the improvements to NT continue, evidence for which shows up
now as "RPC fault" if the UNIHDR structure lengths do not exactly
match up to the length of the data stream.

so, all versions of samba prior to this one have an off-by-one bug
in unicode string lengths.

all versions of NT prior to NT 5 beta 2 could possibly have buffer
problems when receiving badly formatted UNICODE strings.

d0f7b0d915 added in samr commands. assistance in returning the missing functions,
automatically removed because they were "unused", would be appreciated.

2204475c87 tridge the destroyer returns!
prompted by the interpret_security() dead code that Jean-Francois
pointed out I added a make target "finddead" that finds potentially
dead (ie. unused) code. It spat out 304 function names ...

I went through these are deleted many of them, making others static
(finddead also reports functions that are used only in the local
file).

in doing this I have almost certainly deleted some useful code. I may
have even prevented compilation with some compile options. I
apologise. I decided it was better to get rid of this code now and add
back the one or two functions that are needed than to keep all this
baggage.

So, if I have done a bit too much "destroying" then let me know. Keep
the swearing to a minimum :)

One bit I didn't do is the ubibt code. Chris, can you look at that?
Heaps of unused functions there. Can they be made static?

2d77445400 This is a security audit change of the main source.
It removed all ocurrences of the following functions :

sprintf
strcpy
strcat

The replacements are slprintf, safe_strcpy and safe_strcat.

It should not be possible to use code in Samba that uses
sprintf, strcpy or strcat, only the safe_equivalents.

Once Andrew has fixed the slprintf implementation then
this code will be moved back to the 1.9.18 code stream.

118ba4d77a "For I have laboured mightily on Luke's code, and hath broken
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.
