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.

- Fix segfaults in the 'net ads' commands when no password is provided
- Readd --with-ldapsam for 2.2 compatability. This conditionally compiles the
old options, but the actual code is available on all ldap systems.
- Fix shadow passwords (as per work with vl)
- Fix sending plaintext passwords to unicode servers (again vl)
- Add a bit of const to secrets.c functions
- Fix some spelling and grammer by vance.
- Document the -r option in smbgroupedit.
There are more changes in HEAD, I'm only merging the changes I've been involved
with.
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.
J.F.
- 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.
Andrew Bartlett
our authenticaion code - removing some of the duplication from the current
code.
This also gets us *much* closer to supporting a real SAM backend, becouse the
SAM can give us the right info then.
This also changes our service.c code, so that we do a VUID (rather than uid)
cache on the connection struct, and do full NT ACL/NT_TOKEN checks (or cached
equivilant) on every packet, for the same r or rw mode the whole share was open
for.
Andrew Bartlett
setups.
- split up the ads structure into logical pieces. This makes it much
easier to keep things like the authentication realm and the server
realm separate (they can be different).
- allow ads callers to specify that no sasl bind should be performed
(used by "net ads info" for example)
- fix an error with handing ADS_ERROR_SYSTEM() when errno is 0
- completely rewrote the code for finding the LDAP server. Now try DNS
methods first, and try all DNS servers returned from the SRV DNS
query, sorted by closeness to our interfaces (using the same sort code
as we use in replies from WINS servers). This allows us to cope with
ADS DCs that are down, and ensures we don't pick one that is on the
other side of the country unless absolutely necessary.
- recognise dnsRecords as binary when displaying them
- cope with the realm not being configured in smb.conf (work it out
from the LDAP server)
- look at the trustDirection when looking up trusted domains and don't
include trusts that trust our domains but we don't trust
theirs.
- use LDAP to query the alternate (netbios) name for a realm, and make
sure that both and long and short forms of the name are accepted by
winbindd. Use the short form by default for listing users/groups.
- rescan the list of trusted domains every 5 minutes in case new trust
relationships are added while winbindd is running
- include transient trust relationships (ie. C trusts B, B trusts A,
so C trusts A) in winbindd.
- don't do a gratuituous node status lookup when finding an ADS DC (we
don't need it and it could fail)
- remove unused sid_to_distinguished_name function
- make sure we find the allternate name of our primary domain when
operating with a netbiosless ADS DC (using LDAP to do the lookup)
- fixed the rpc trusted domain enumeration to support up to approx
2000 trusted domains (the old limit was 3)
- use the IP for the remote_machine (%m) macro when the client doesn't
supply us with a name via a netbios session request (eg. port 445)
- if the client uses SPNEGO then use the machine name from the SPNEGO
auth packet for remote_machine (%m) macro
- add new 'net ads workgroup' command to find the netbios workgroup
name for a realm
Authenticaions will now attempt to use winbind, and only fall back to
'ntdomain' (the old security=domain) code if that fails (for any reason,
including wrong password).
I'll fix up the authenticaion code to better handle the different types of
failures in the near future.
Andrew Bartlett
This updates the 'winbind' authentication module and winbind's 'PAM' (actually
netlogon) code to allow smbd to cache connections to the DC.
This is particulary relevent when we need mutex locks already - there is no
parallelism to be gained anyway.
The winbind code authenticates the user, and if successful, passes back the
'info3' struct describing the user. smbd then interprets that in exactly the
same way as an 'ntdomain' logon.
Also, add parinoia to winbind about null termination.
Andrew Bartlett
the servers netbios name when we don't need it. This also fixes ADS
mode when the DC has netbios disabled.
- if the password server is specified as an IP then actually use that
IP, don't do a lookup for the servers name :)
this one fixes swat not working with browsers that set more then one language.
along the way implemented language priority in web/neg_lang.c with bubble sort
also changet str_list_make to be able to use a different separator string
Simo.
authentication - we can have an NT hash in the LM hash feild.
(I need to double-check this fix with tpot, who discovered it).
Also remove silly casts back and forth between uchar and char.
Andrew Bartlett
becouse thats what Win2k gives when the PDC is down.
Some of these might better go to other errors, but the Win2k text message for
'unsuccessful' is not particularly useful. (A device attached to the system is
not functioning...)
Andrew Bartlett
The previous code both had basic logic flaws in it, and some subtle
issues regarding the Win2k info3 response.
I've tested this against Samba (it looks like that was missed last time
due to the 'called name' corruption - which broke my testsuite) and
accomidated what I've seen from a info3 printout jmcd gave me.
I'll get this tested fully as soon as I get my VMware going again.
Andrew Bartlett
It extends the 'server mutex' to conver security=server, becouse the connection
race condition exists here too, and while people *should* use security=domain,
some sites don't....
(This probably should be done in 2.2 as well).
Also, start to actually extract and use the information that the remote
server returns in the info3 struct.
The server mutex code is now in a new file.
Andrew Bartlett
deveopers hack to always send a fixed challange, for the benifit
of tutorials and packet sniffing etc.
Enabling this module removes all security, so its a --enable-developer
option.
