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).

name_status_find() call here should look up a #1c name instead of #1d.
This fixes some bugs currently with BDC authentication in winbindd and in
smbd as you can't query the #1d name with the ip address of a BDC.

subystem.
The particular aim is to modularized the interface - so that we
can have arbitrary password back-ends.
This code adds one such back-end, a 'winbind' module to authenticate
against the winbind_auth_crap functionality. While fully-functional
this code is mainly useful as a demonstration, because we don't get
back the info3 as we would for direct ntdomain authentication.
This commit introduced the new 'auth methods' parameter, in the
spirit of the 'auth order' discussed on the lists. It is renamed
because not all the methods may be consulted, even if previous
methods fail - they may not have a suitable challenge for example.
Also, we have a 'local' authentication method, for old-style
'unix if plaintext, sam if encrypted' authentication and a
'guest' module to handle guest logins in a single place.
While this current design is not ideal, I feel that it does
provide a better infrastructure than the current design, and can
be built upon.
The following parameters have changed:
- use rhosts =
This has been replaced by the 'rhosts' authentication method,
and can be specified like 'auth methods = guest rhosts'
- hosts equiv =
This needs both this parameter and an 'auth methods' entry
to be effective. (auth methods = guest hostsequiv ....)
- plaintext to smbpasswd =
This is replaced by specifying 'sam' rather than 'local'
in the auth methods.
The security = parameter is unchanged, and now provides defaults
for the 'auth methods' parameter.
The available auth methods are:
guest
rhosts
hostsequiv
sam (passdb direct hash access)
unix (PAM, crypt() etc)
local (the combination of the above, based on encryption)
smbserver (old security=server)
ntdomain (old security=domain)
winbind (use winbind to cache DC connections)
Assistance in testing, or the production of new and interesting
authentication modules is always appreciated.

All this stuff was being pulled in due to *one* unneeded call to
fetch a domain SID which smbpasswd already puts in the database...

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.

fault is returned but not propagated up as an error.

they can have general effect.
Fixed up workstaion support in the rest of samba, so that we can do these
checks.
Pass through the workstation for cli_net_logon(), if supplied.
(This used to be commit 7f04a139b2)
In particuar, it moves the domain_client_validate stuff out of
auth_domain.c to somwhere where they (I hope) they can be shared
with winbind better. (This may need some work)
The main purpose of this patch was however to improve some of the
internal documentation and to correctly place become_root()/unbecome_root()
calls within the code.
Finally this patch moves some more of auth.c into other files, auth_unix.c
in this case.
Andrew Bartlett
(This used to be commit ea1c547ac8)
samba-technical a few weeks ago.
The idea here is to standardize the checking of user names and passwords,
thereby ensuring that all authtentications pass the same standards. The
interface currently implemented in as
nt_status = check_password(user_info, server_info)
where user_info contains (mostly) the authentication data, and server_info
contains things like the user-id they got, and their resolved user name.
The current ugliness with the way the structures are created will be killed
the next revision, when they will be created and malloced by creator functions.
This patch also includes the first implementation of NTLMv2 in HEAD, but which
needs some more testing. We also add a hack to allow plaintext passwords to be
compared with smbpasswd, not the system password database.
Finally, this patch probably reintroduces the PAM accounts bug we had in
2.2.0, I'll fix that once this hits the tree. (I've just finished testing
it on a wide variety of platforms, so I want to get this patch in).
(This used to be commit b30b6202f3)
changeover. For my own sainity I have created a new function to fill out both
the header and buffer for a string in an RPC struct. This DOES NOT take a
length argument, only the actual string to be placed.
The RPC code is currently littered with code that does init_uni_hdr() followed
immidiatly by init_unistr2(), and often the length argument is wrong. (It was
for the code I changed, even before the charset stuff). Another bug where we
made strings AT LEAST MAX_UNICODE_LEN long hid this bug.
This works for loopback connections to Samba, and can't be any more broke than
it was before :-). (We had double and revese conversions, fun...).
In particular this makes us multibyte complient.
In any case, if there are no objections I will slowly convert other bits of
code to the same system.
(This used to be commit cf1d1cd9d6)
This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
(This used to be commit debb471267)
for and ignore ERRmoredata errors as the client library doesn't support
32-bit error messages.
Added some annotations for the RPC pipe code to make it a bit clearer
maybe.
(This used to be commit f179e0ff61)
on different pipes. This seriously confuses NT. Unfortunately HEAD
branch is limited to one rpc pipe per connection as the fnum is stored
inside the cli_state structure. It should really be broken out into
it's own structure so multiple pipes can be opened on one TCP/IP socket.
What a good idea! But look over here! I've already done it in another
workarea but it will require a day or two to refactor some of the internal
samba rpc client stuff (i.e netlogon requests) so it will remain uncommitted
for another while.
(This used to be commit 657804f3be)
We were reading the endainness in the RPC header and then never propagating
it to the internal parse_structs used to parse the data.
Also removed the "align" argument to prs_init as it was *always* set to
4, and if needed can be set differently on a case by case basis.
Now ready for AS/U testing when Herb gets it set up :-).
Jeremy.
(This used to be commit 0cd37c831d)
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.
(This used to be commit bda1d6d4a4)
with a PDC that has international netbios name and domain name. There's
still quite a bit of i18n stuff to fix though...
(This used to be commit 79045bd72a)
to search for a DC to authenticate to using the "*" syntax than ensure
that for the first hour after the password change is searches for the
PDC using the 1B name not the 1C name as domain replication may not
have occured.

(This used to be commit c25533de99)
When chaining together long lines of bloody "if" statements, which should
logically be separated, and one of them allocates memory, remember to
*free* it *WHETHER OR NOT THE IF STATEMENTS SUCCEEDED* !!!!
Yes I do consider this a bug in the coding style of Tridge, Rusty, Tim et al. :-).
I'm just pissed 'cos this took 4 hours to track down even with an insure error report
stating me in the face and also Ben Woodward looking over the code with me :-).
