In particular this commit focusses on:
Adding the new 'pass changed now' helper function.
While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.
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.

This moves the check that ensures that the account being looked up is the same
account as the machine logged in as to the front, before we even start with
passdb.
Merge for 2.2.2?
Andrew Bartlett
they can have general effect.
Fixed up workstaion support in the rest of samba, so that we can do these
checks.
Pass through the workstation for cli_net_logon(), if supplied.
- 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.

when samba acting as a PDC.
I also removed a pdb_free_sam(sampass), because it sampass was never
initialized before...
Please abartlet can you check this patch is ok?
I feel like this was a bad check-in
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 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.
now in pipe struct (where used) rather than user_struct.
Secured machine account password changing in srv_netlog_nt.c - ensure
that only the given machine can change its own password. May need to
free this up later for NT admin tools, but this is a fail-safe secure
position for now.
