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This has been replaced by the 'rhosts' authentication method,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.

per-share. I beleive that almost all the things that this could have done on
a per-share basis can be done with other tools, like 'force user'.
Almost all the user's of this paramater used it as a global anyway...
While this is one step at a time, I hope it will allow me to considerably
simplfy the make_connection() code, particularly for the user-level security
case.
This already removes an absolute truckload of extra attempted password lookups
on the guest account.

This changes the way we process guest logons - we now treat them as normal
logons, but set the 'guest' flag. In particular this is needed becouse Win2k
will do an NTLMSSP login with username "", therefore missing our previous guest
connection code - this is getting a pain to do as a special case all over the
shop.
Tridge: We don't seem to be setting a guest bit for NTLMSSP, in either the
anonymous or authenticated case, can you take a look at this?
Also some cleanups in the check_password() code that should make some of the
debugs clearer.
Various other minor cleanups:
- change the session code to just take a vuser, rather than having to do a
vuid lookup on vuser.vuid
- Change some of the global_client_caps linking
- Better debug in authorise_login(): show the vuid.

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.

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.

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