to make full use of the new talloc() interface. Discussed with Volker
and Jeremy.
* remove the internal mem_ctx and simply use the talloc()
structure as the context.
* replace the internal free_fn() with a talloc_destructor() function
* remove the unnecessary private nested structure
* rename SAM_ACCOUNT to 'struct samu' to indicate the current an
upcoming changes. Groups will most likely be replaced with a
'struct samg' in the future.
Note that there are now passbd API changes. And for the most
part, the wrapper functions remain the same.
While this code has been tested on tdb and ldap based Samba PDC's
as well as Samba member servers, there are probably still
some bugs. The code also needs more testing under valgrind to
ensure it's not leaking memory.
But it's a start......
(This used to be commit 19b7593972)
* remove pdb_context data structure
* set default group for DOMAIN_RID_GUEST user as RID 513 (just
like Windows)
* Allow RID 513 to resolve to always resolve to a name
* Remove auto mapping of guest account primary group given the
previous 2 changes

talloc_string_sub. Someone with time on his hands could convert all the
callers of all_string_sub to this.
realloc_string_sub is *only* called from within substitute.c, it could be
moved there I think.

nested group support. Always add the BUILTIN\Administrators
SID to a Domain Admins token.
This solves the extra steps of establishing a group map for
the local Administrators SID in order to control services.
Windows also tends to expect the Administrators group to be
usable when setting up security permissions on shares.
Volker's work will probably fix this long term, but this
gets us past some of the setup hurdles for 3.0.21.
(This used to be commit 170b6a68bc)
logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT
or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes
the auth module interface to 2 (from 1). The effect of this is
that clients can access resources as a machine account if they
set these flags. This is the same as Windows (think of a VPN
where the vpn client authenticates itself to a VPN server
using machine account credentials - the vpn server checks
that the machine password was valid by performing a machine
account check with the PDC in the same was as it would a
user account check. I may add in a restriction (parameter)
to allow this behaviour to be turned off (as it was previously).
That may be on by default.
Andrew Bartlett please review this change carefully.

We were filling in our name as the server which processed the login, even
when it was done by a trusted DC.
Thanks to John Janosik <jpjanosi@us.ibm.com> for the fix.

Add 'log nt token command' parameter. If set, %s is replaced with the user
sid, and %t takes all the group sids.

* rewrote the tdb layout of privilege records in account_pol.tdb
(allow for 128 bits instead of 32 bit flags)
* migrated to using SE_PRIV structure instead of the PRIVILEGE_SET
structure. The latter is now used for parsing routines mainly.
Still need to incorporate some client support into 'net' so
for setting privileges. And make use of the SeAddUserPrivilege
right.
(This used to be commit 41dc7f7573)
(based on Simo's code in trunk). Rewritten with the
following changes:
* privilege set is based on a 32-bit mask instead of strings
(plans are to extend this to a 64 or 128-bit mask before
the next 3.0.11preX release).
* Remove the privilege code from the passdb API
(replication to come later)
* Only support the minimum amount of privileges that make
sense.
* Rewrite the domain join checks to use the SeMachineAccountPrivilege
instead of the 'is a member of "Domain Admins"?' check that started
all this.
Still todo:
* Utilize the SePrintOperatorPrivilege in addition to the 'printer admin'
parameter
* Utilize the SeAddUserPrivilege for adding users and groups
* Fix some of the hard coded _lsa_*() calls
* Start work on enough of SAM replication to get privileges from one
Samba DC to another.
* Come up with some management tool for manipultaing privileges
instead of user manager since it is buggy when run on a 2k client
(haven't tried xp). Works ok on NT4.
(This used to be commit 77c10ff9aa)
The old #ifdef JRATEST-block was copying 16 bytes and thus overwriting
acct_flags with bizarre values, breaking a lot of things.
This patch is successfully running in a production environment for quite
some time now and is required to finally allow Exchange 5.5 to access
another Exchange Server when both are running on NT4 in a
samba-controlled domain. This also allows Exchange Replication to take
place, Exchange Administrator to access other Servers in the network,
etc. Fixes Bugzilla #1136.
Thanks abartlet for helping me with that one.

functions so we can funnel through some well known functions. Should help greatly with
malloc checking.
HEAD patch to follow.

(This used to be commit 620f2e608f)
abartlet, I'd like to ask you to take a severe look at this!
We have solved the problem to find the global groups a user is in twice: Once
in auth_util.c and another time for the corresponding samr call. The attached
patch unifies these and sends them through the passdb backend (new function
pdb_enum_group_memberships). Thus it gives pdb_ldap.c the chance to further
optimize the corresponding call if the samba and posix accounts are unified by
issuing a specialized ldap query.
The parameter to activate this ldapsam behaviour is
ldapsam:trusted = yes

setups on its way to open a pipe. This gets rid of many round-trips to the
LDAP server during logon by setting up the server_info_guest once and not
asking the LDAP server and nss every time. Make sure that the ldap connection
is reopened in the child. (I did not look at the sql backends.)
Volker
(This used to be commit 3298f6105e)
Use the fully qualified DOMAIN\user format for 'security = domain|ads'
and apply after authentication has succeeded.
* also change fill_domain_username() to only lowercase the username
and not the domain+username. This was a cosmetic fix only.
makes the output more consistent with %D and %U.
(This used to be commit 30ee2d5b09)
for setting up an schannel connection. This solves the problem
of a Samba DC running winbind, trusting a native mode AD domain,
and needing to enumerate AD users via wbinfo -u.
(This used to be commit e9f109d1b3)
For a (very) long time, we have had a bug in Samba were an NTLMv2-only
PDC would fail, because it converted the password into NTLM format for
checking.
This patch performs the direct comparison required for interactive
logons to function in this situation. It also removes the 'auth flags', which
simply where not ever used.
Natrually, this plays with the size of structures, so rebuild, rebuild
rebuild...

- Fill in the 'backup' idea of a domain, if the DC didn't supply one. This
doesn't seem to occour in reality, hence why we missed the typo.
lib/charcnv.c:
lib/smbldap.c:
libads/ldap.c:
libsmb/libsmbclient.c:
printing/nt_printing.c:
- all the callers to pull_utf8_allocate() pass a char ** as the first
parammeter, so don't make them all cast it to a void **
nsswitch/winbind_util.c:
- Allow for a more 'correct' view of when usernames should be qualified
in winbindd. If we are a PDC, or have 'winbind trusted domains only',
then for the authentication returns stip the domain portion.
- Fix valgrind warning about use of free()ed name when looking up our
local domain. lp_workgroup() is maniplated inside a procedure that
uses it's former value. Instead, use the fact that our local domain is
always the first in the list.
Andrew Bartlett
(This used to be commit 494781f628)
- NTLM2 support in the server
- KEY_EXCH support in the server
- variable length session keys.
In detail:
- NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).
* This is known as 'NTLMv2 session security' *
(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes. We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)
This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed. This also needs to be turned off for
'security=server', which does not support this.
- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.
- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.
- There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation.
- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.
- The other big change is to allow variable length session keys. We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter. However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.
* This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *
- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe. This
should help reduce some of the 'it just doesn't work' issues.
- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer. (just allocate)
REMEMBER to make clean after this commit - I have changed plenty of data structures...
(This used to be commit f3bbc87b0d)
sesssetup to fall back to 'user' instaed of failing is REA.LM\user
doesn't exist.
also fix include line in smb_acls.h as requested by metze
