The auth_authsupplied_info typedef is now just a plain struct - auth_context,
but it has been modified to contain the function pointers to the rest
of the auth subsystem's components.
(Who needs non-static functions anyway?)
In working all this mess out, I fixed a number of memory leaks and moved the
entire auth subsystem over to talloc().
Note that the TALLOC_CTX attached to the auth_context can be rather long-lived,
it is provided for things that are intended to live as long. (The
global_negprot_auth_context lasts the whole life of the smbd).
I've also adjusted a few things in auth_domain.c, mainly passing the domain as
a paramater to a few functions instead of looking up lp_workgroup(). I'm
hopign to make this entire thing a bit more trusted domains (as PDC) freindly
in the near future.
Other than that, I moved a bit of the code around, hence the rather messy diff.

- Move rpc_client/cli_trust.c to smbd/change_trust_pw.c
- It hasn't been used by anything else since smbpasswd lost its -j
- Add a TALLOC_CTX to the auth subsytem. These are only valid for the length
of the calls to the individual modules, if you want a longer context hide it
in your private data.
Similarly, all returns (like the server_info) should still be malloced.
- Move the 'ntdomain' module (security=domain in oldspeak) over to use the new
libsmb domain logon code. Also rework much of the code to use some better
helper functions for the connection - getting us much better error returns
(the new code is NTSTATUS).
The only remaining thing to do is to figure out if tpot's 0xdead 0xbeef for
the LUID feilds is sufficient, or if we should do random LUIDs as per the old
code.
Similarly, I'll move winbind over to this when I get a chance.
This leaves the SPOOLSS code and some cli_pipe code as the only stuff still in
rpc_client, at least as far as smbd is concerned.
While I've given this a basic rundown, any testing is as always appriciated.

- 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 ;-)

We now default encrypt passwords = yes
We now check plaintext passwords (however aquired) with the 'sam' backend
rather than unix, if encrypt passwords = yes.
(this kills off the 'local' backed. The sam backend may be renamed in its
place)
The new 'samstrict' wrapper backend checks that the user's domain is one of
our netbios aliases - this ensures that we don't get fallback crazies with
security = domain.
Similarly, the code in the 'ntdomain' and 'smbserver' backends now checks
that the user was not local before contacting the DC.
The default ordering has changed, we now check the local stuff first - but
becouse of the changes above, we will really only ever contact one
auth source.

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.

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.

flags so we just do a 'normal' session setup.
Also add some parinoia code to detect when sombody attempts to do a 'normal'
session setup when spnego had been negoitiated.

smbd/password.c: We don't use globals here anymore
smbd/reply.c: Tidyness, global_myworkgroup must die!
smbd/service.c: Move some of the make_connection code into a helper
function.
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).
