178f6a64b2 challange -> challenge

d0a2faf78d This is another rather major change to the samba authenticaion
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  This has been replaced by the 'rhosts' authentication method,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.

f8e2baf39e Added NT_USER_TOKEN into server_info to fix extra groups problem.
Got "medieval on our ass" about const warnings (as many as I could :-).

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.

6f0b8a38ec Added some extra fields to the auth_serversupplied_info structure.
To obtain the full group membership of a user (i.e nested groups on a
win2k native mode server) it is necessary to merge this list of groups
with the groups returned by winbindd when creating an nt access token.

This breaks winbindd linking while AB and I sync up our changes to the
authentication subsystem.

b800a36b1c Some patches to authentication:
- the usersupplied_info now contains a smb_username (as it comes across on
   the wire) and a unix_username (after being passed through mapping
   functions)

 - when doing security={server,domain} use the smb_username, otherwise use
   the unix_username

6ad80352dd This patch does a number of things, mostly smaller than they look :-)
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.

5b33eaedde Added include guards...
We may need to rename this file smbauth.h, as auth.h
is so generic it will probably conflict with system header
files on some systems.

986372901e This is my 'Authentication Rewrite' version 1.01, mostly as submitted to
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).
