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This has been replaced by the 'rhosts' authentication method,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

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.

In particular this commit focuses on:
Changing the Get_Pwnam code so that it can work in a const-enforced
environment.
While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.
----
These changes allow for 'const' in the Samba tree.
There are a number of good reasons to do this:
- I want to allow the SAM_ACCOUNT structure to move from wasteful
pstrings and fstrings to allocated strings. We can't do that if
people are modifying these outputs, as they may well make
assumptions about getting pstrings and fstrings
- I want --with-pam_smbpass to compile with a slightly sane
volume of warnings, currently its pretty bad, even in 2.2
where is compiles at all.
- Tridge assures me that he no longer opposes 'const religion'
based on the ability to #define const the problem away.
- Changed Get_Pwnam(x,y) into two variants (so that the const
parameter can work correctly): - Get_Pwnam(const x) and
Get_Pwnam_Modify(x).
- Reworked smbd/chgpasswd.c to work with these mods, passing
around a 'struct passwd' rather than the modified username

The big one is a global change to allow us to NULLify the free'ed pointer to a
former passdb object. This was done to allow idra's SAFE_FREE() macro to do
its magic, and to satisfy the input test in pdb_init_sam() for a NULL pointer
to start with.
This NULL pointer test was what was breaking the adding of accounts up until
now, and this code has been reworked to avoid duplicating work - I hope this
will avoid a similar mess-up in future.
Finally, I fixed a few nasty bugs where the pdb_ fuctions's return codes were
being ignored. Some of these functions malloc() and are permitted to fail.
Also, this caught a nasty bug where pdb_set_lanman_password(sam, NULL) acheived
precisely didilly-squat, just returning False. Now that we check the returns
this bug was spotted. This could allow different LM and NT passwords.
- the pdbedit code needs to start checking these too, but I havn't had a
chance to fix it.
I have also fixed up where some of the password changing code was using the
pdb_set functions to store *internal* data. I assume this is from a previous
lot of mass conversion work...
Most likally (and going on past experience) I have missed somthing, probably in
the LanMan password change code which I havn't yet been able to test, but this
lot is in much better shape than it was before.
If all this is too much to swallow (particularly for 2.2.2) then just adding a
sam_pass = NULL to the particular line of passdb.c should do the trick for the
ovbious bug.

Add the ability for swat to run in non-root-mode (ie non-root from inetd).
- we still need some of the am_root() calls fixed however.

simply not doing Get_Pwnam() calls in pass_check.c
We now make *one* sys_getpnam() call in cgi.c and we always call PAM no matter
what it returns. We also no longer run the password cracker for these logins.
The truly parinod will note the slight difference in call paths, in that we only
call crypt for valid password structs (if not --with-pam). The truly parinoid
don't run SWAT either, so I don't think this is an issue.

- 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

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.
