We check passdb becouse the user might have things like a logon script set,
but we have to check the passdb becouse the user might not be in smbpasswd at
all.
This is in preperation for the removal of unixsam as an assuption.

running winbind has been broken. This fixes that, by removing assumptions
about being able to call sid_to_uid() at will. This whole area needs
revising when we get groups into the PDB.
Andrew Bartlett
it can be used for 'net rpc join'.
Also fix a bug in our server-side NTLMSSP code - a client without any domain
trust links to us may calculate the NTLMv2 response with "" as the domain.
Andrew Bartlett
- Don't use pstrcpy into an allocated string - use safe_strcpy() directly
instead.
- Keep a copy of the 'server_info' attached to the vuid. In future use this
for things like the session key, homedir and full name instead of current
copies.
- Try to avoid memory leak/segfault on Realloc failure
- clear up #endif comments

of the SWAT code, and adding a base64 encoder.
The main purpose of this patch is to add NTLMSSP support to 'ntlm_auth', for
use with Squid. Unfortunetly the squid side doesn't quite support what we need
yet.
Changes to winbind to get us the info we need, and a couple of consequential
changes/cleanups in the rest of the code.
Andrew Bartlett
- fix a crash when a second NTLMSSP session tried to free the first
- fix a crash due to some NULL pointers in the Add Printer Wizard (or read
printer code too it appears). As far as I can tell it's just that the
GUID just might not exist.
Andrew Bartlett
Controller. As we have had a number of attempts at this over the last little
while, I need to get my test rig going, and give this whole area a poke...
Meanwhile, if you want to use this, just adjust your 'auth methods' line to use
samstrict_dc...
Andrew Bartlett
This tries to extract our server-side code out of sessetup.c, and into a more
general lib. I hope this is only a temporay resting place - I indend to
refactor it again into an auth-subsystem independent lib, using callbacks.
Move some of our our NTLMSSP #defines into a new file, and add two that I found
in the COMsource docs - we seem to have a double-up, but I've verified from
traces that the NTLMSSP_TARGET_TYPE_{DOMAIN,SERVER} is real.
This code also copes with ASCII clients - not that we will ever see any here,
but I hope to use this for HTTP, were we can get them. Win2k authenticates
fine under forced ASCII, btw.
Tested with Win2k, NTLMv2 and Samba's smbclient.

routines). In particular, we now better support the NT# in LM feild, and the
LMv2 password scheme. (LMv2 is basicly NTLMv2 capped at 24 bytes, slightly
more secure, and in the LM feild for compatiblity).
Thanks to the Samba-TNG team and Luke Leighton for various descriptions of this
algorithm, and to MS for a solution that seems to actually make sense for once
:-).
Andrew Bartlett
don't need a second just for pdb.
Also, remove magic 'is lp_guest_account' test - the magic RID should be
up to the passdb backend to set.
Andrew Bartlett
This patch makes Samba compile cleanly with -Wwrite-strings.
- That is, all string literals are marked as 'const'. These strings are
always read only, this just marks them as such for passing to other functions.
What is most supprising is that I didn't need to change more than a few lines of code (all
in 'net', which got a small cleanup of net.h and extern variables). The rest
is just adding a lot of 'const'.
As far as I can tell, I have not added any new warnings - apart from making all
of tdbutil.c's function const (so they warn for adding that const string to
struct).
Andrew Bartlett
90% fix for CR 1076. The password server parameter will no take things
like
password server = DC1 *
which means to contact DC1 first and the go to auto lookup if it
fails.

- add static remove unnneded prototype
- move become_root() to just around pdb calls, so as to make it easier to
remove when we kill off this silly idea
- Change auth_sam to do 'account before password' rather than 'password before
account'. This means that we match Win2k in giving 'account disabled' instead
of 'wrong password' if the wrong password to a disabled account is used.
Andrew Bartlett
The actual design change is relitivly small however:
It all goes back to jerry's 'BOOL store', added to many of the elements in a
SAM_ACCOUNT. This ensured that smb.conf defaults did not get 'fixed' into
ldap. This was a great win for admins, and this patch follows in the same way.
This patch extends the concept - we don't store values back into LDAP unless
they have been changed. So if we read a value, but don't update it, or we
read a value, find it's not there and use a default, we will not update
ldap with that value. This reduced clutter in our LDAP DB, and makes it
easier to change defaults later on.
Metze's particular problem was that when we 'write back' an unchanged value,
we would clear any muliple values in that feild. Now he can still have his
mulitivalued 'uid' feild, without Samba changing it for *every* other
operation.
This also applies to many other attributes, and helps to eliminate a nasty
race condition. (Time between get and set)
This patch is big, and needs more testing, but metze has tested usrmgr, and
I've fixed some pdbedit bugs, and tested domain joins, so it isn't compleatly
flawed ;-).
The same system will be introduced into the SAM code shortly, but this fixes
bugs that people were coming across in production uses of Samba 3.0/HEAD, hence
it's inclusion here.
Andrew Bartlett
Basicly, the password and the salt must be taken from the same place in both
passwd and shadow based systems. Taking salt from one, and password from the
other just doesn't work.
So pull them from passwd, then overwrite them if need be.
When modifying this file, watch the #ifdef hell - as vl found out, some
variables are globals - but only with #ifndef WITH_PAM, and the code jumps all
over the place with the password cracker.
Getting double-reviews of any change to this file highly advised, it is one of
our most system-specifc areas of code.
(So now I get to take the blame for this one... :-)
Andrew Bartlett
Volker, I would like to understand what you are trying to do here...
I'll trust that it's broken (this code is certainly not well tested) but I do
want to keep a close eye on the fixes...
Andrew Bartlett
'security = user', 'encrypt passwords = no' did not work anymore.
This is on quite a standard SuSE 7.3, ./configure.developer --with-tdbsam.
I can provide a config.log / config.h on demand.
Please re-check for consequences, I don't really oversee that file.
Thanks,
Volker

It includes a conversion of make_user_info*() to NTSTATUS and some minor
changes to other files.
It also picks up on a nasty segfault that can occour in some security=domain
cases.
Andrew Bartlett
changed cli_nt_setup_creds() to call cli_net_auth_2 or cli_net_auth_3 based on a switch.
pass also the negociation flags all the way.
all the places calling cli_nt_setup_creds() are still using cli_net_aut2(), it's just for future use and for rpcclient.
in the future we will be able to call auth_2 or auth_3 as we want.

- Don't print an uninitialised buffer in service.c
- Change some charcnv.c functions to take smb_ucs2_t ** instead of void **
- Update NTLMv2 code to use dynamic buffers
- Update experimental SMB signing code - still more work to do
- Move sys_getgrouplist() to SAFE_FREE() and do a DEBUG() on initgroups()
failure.
