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This has been replaced by the 'rhosts' authentication method,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

winbindd_lookup_sid_by_name. Also if the lookup fails then clobber
the output parameters rather than leaving them looking potentially
valid.
Add doxygen.

check for a static is_initialised boolean.

There was a bug in cli_lsa_lookup_name/lookup_sid where NT_STATUS_NONE_MAPPED was
being mapped to NT_STATUS_OK, and also the *wrong* number of entries mapped
was being returned. The correct field is mapped_count, *NOT* num_entries.

be easily added (a one liner) once we know the correct error codes returned
by a W2K DC.
All other winbindd calls should go through a similar transparent caching layer
(and will soon).

Ignore the SIGUSR1 signal before we install a handler for it as glibc (?)
seems to just print out "User defined signal 1" and exit if no handler
is installed.
(This used to be commit 1212591095)
the currently open connections when winbindd receives a USR1 signal.
Hmm - I've just realised this will conflict with the messaging code
but we don't use that yet.
(This used to be commit caef54e400)
requested name does not have a winbind separator character. This
makes the intent explicit. Tim, contact me if this is not what
you indended.

pam authentication. This allows us to link in less other crap.
Authenticating with a challenge/response doesn't seem to work though - we
always get back NT_STATUS_WRONG_PASSWORD.

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.
Andrew Bartlett
(This used to be commit f70fb819b2)
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.
(This used to be commit 4eeb7bcd78)
In particular this commit focuses on:
Actually adding the 'const' to the passdb interface, and the flow-on changes.
Also kill off the 'disp_info' stuff, as its no longer used.
While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.
----
These changes introduces a large dose of 'const' to 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
---
This finishes this line of commits off, your tree should now compile again :-)

per-call basis rather than per-connection.
Had a bit more of a reformatting fest.
Still need to run it through insure and handle downed connections.
(This used to be commit 46fe5a8fb9)
Pass domain structure around in cache code rather than the domain name.
Some misc reformatting to make things look prettier.
(This used to be commit 295dd2a581)
what was I thinking with those 4 character tabs?)
We now pass our winbindd test suite again!
Still to do:
- talloc_ctx on a per winbindd request basis not per connection
- clean up old crap we don't use any more
- test against multiple BDCs (I know this isn't going to work - group/user
handles have to be made against the same DC the domain and basic handles
are.
- implement network and dc failure recovery
(This used to be commit dc4ca0e0bd)
- implemented some of the sam related connection manager routines
- fill in group id and gecos fields for getpwnam/getpwuid routines
- convert querydispinfo to cm
- getent passwd now works
Now for the group related routines...
(This used to be commit 4f8ea87787)
I've wrapped up all the decisions about managing, making and closing
connections into a connection manager in nsswitch/winbindd_cm.c.
It's rather incomplete at the moment - only querying basic user info works
at the moment (i.e finger -m DOMAIN/user) and everything else is broken.
Jeremy, please take a look and I'll start moving across the rest of
winbindd to this new system.
(This used to be commit c369cf5af7)
- 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
(This used to be commit d34fd8ec07)
Authentication Protocol (CRAP) takes a tuple of (username, random
challenge, encrypted lm password, encrypted nt password) where the
passwords are encrypted with the random challenge ala ntlmssp.
(This used to be commit 11f72a78e3)
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.

(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)
works much better with trusted domains whose DCs cannot be reached.
I'm pretty impressed with how much faster winbindd is in HEAD rather than
TNG. A lot fewer unecessary name lookups are performed and it feels a lot
zippier now.
(This used to be commit 36413784ae)
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)
but the code suffered from bitrot and is not now reentrant. That means
we can get bizarre behaviour
i've fixed this by making next_token() reentrant and creating a
next_token_nr() that is a small non-reentrant wrapper for those lumps
of code (mostly smbclient) that have come to rely on the non-reentrant
behaviour
(This used to be commit 674ee2f1d1)
