malloc checking.
HEAD patch to follow.

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

not exactly match what you would expect.
XP workstations during login actually do this, so we should better become a
bit more correct. The LDAP query issued is not really fully optimal, but it is
a lot faster and more correct than what was there before. The change in
passdb.h makes it possible that queryuseraliases is done with a single ldap
query.

I've been grumbling about under-efficient calls in SAMR, and finally
got around to fixing some of them.
We now call sys_getgroups() (which in turn calls initgroups(), until
glibc 3.4 is released) to figure out a user's group membership. This
is far, far more efficient than scanning all the groups looking for a
match, and is still the 'posix way', just using an effiecient call.
The seperate issue of 'who is in this group' remains, but this one has
been biting some people.
I need to talk to VL about how best to exersise nasty corner cases,
but my initial tests hold strong. (The code is also much simpiler
than before, which has to count for something :-)

* don't fall back to unmapped UNIX group for
get_local_group_from_sid()
* remove an extra become/unbecome_root() pair
from group enumeration
(This used to be commit da12bbdb0d)
(also fixed the call to return the real groups and not a mocked
up list)
Fixed simple compiler warning in srv_lsa_ds.c

As abartlet rememberd me NT_STATUS_IS_ERR != !NT_STATUS_IS_OK
This patch will cure the problem.
Working on this one I found 16 functions where I think NT_STATUS_IS_ERR() is
used correctly, but I'm not 100% sure, coders should check the use of
NT_STATUS_IS_ERR() in samba is ok now.
Simo.
(This used to be commit c501e84d41)
The code was nice, but put in the wrong place (group mapping) and not
supported by most of the code, thus useless.
We will put back most of the code when our infrastructure will be changed
so that privileges actually really make sense to be set.
This is a first patch of a set to enhance all our mapping code cleaness and
stability towards a sane next beta for 3.0 code base
Simo.
(This used to be commit e341e7c49f)
We really need idmap_ldap to have a good solution with ldapsam, porting
it from the prvious code is beeing made, the code is really simple to do
so I am confident it is not a problem to commit this code in.
Not committing it would have been worst.
I really would have been able to finish also the group code, maybe we can
put it into a followin release after 3.0.0 even if it may be an upgrade
problem.
The code has been tested and seem to work right, more testing is needed for
corner cases.
Currently winbind pdc (working only for users and not for groups) is
disabled as I was not able to make a complete group code replacement that
works somewhat in a week (I have a complete patch, but there are bugs)
Simo.

this as thier list of groups, rather than do a seperate lookup. This NT_TOKEN
is originally initgroups() (or equiv) based.
We currently send all sids in our domain, perhaps this should be further
restricted, but this works for now.

The work here includes:
- metze' set/changed patch, which avoids making changes to ldap on unmodified
attributes.
- volker's group mapping in passdb patch
- volker's samsync stuff
- volkers SAMR changes.
- mezte's connection caching patch
- my recent changes (fix magic root check, ldap ssl)

smbd, and also makes it much cleaner inside winbindd.
It is mostly my code, with a few changes and testing performed by Alexander
Bokovoy <a.bokovoy@sam-solutions.net>. ab has tested it in security=domain and
security=ads, but more testing is always appricatiated.
The idea is that we no longer cart around a 'domain\user' string, we keep them
seperate until the last moment - when we push that string into a pwent on onto
the socket.
This removes the need to be constantly parsing that string - the domain prefix
is almost always already provided, (only a couple of functions actually changed
arguments in all this).
Some consequential changes to the RPC client code, to stop it concatonating the
two strings (it now passes them both back as params).
I havn't changed the cache code, however the usernames will no longer have a
double domain prefix in the key string. The actual structures are unchanged
- but the meaning of 'username' in the 'rid' will have changed. (The cache is
invalidated at startup, so on-disk formats are not an issue here).
Andrew Bartlett
(This used to be commit e870f0e727)
- removed the ugly as hell sam_logon_in_ssb variable, I changed a bit the
definition of standard_sub_basic() to cope with that.
- removed the smb.conf: 'domain admin group' and 'domain guest group'
parameters ! We're not playing anymore with the user's group RIDs !
- in get_domain_user_groups(), if the user's gid is a group, put it first
in the group RID list.
I just have to write an HOWTO now ;-)

not the privileges. Usually we don't need them, so the memory is free
early.
lib/util_sid.c: added some helper functions to check an SID.
passdb/passdb.c: renamed local_lookup_rid() to local_lookup_sid() and pass
an RID all the way. If the group doesn't exist on the domain SID,
don't return a faked one as it can collide with a builtin one. Some rpc
structures have been badly designed, they return only rids and force the
client to do subsequent lsa_lookup_sid() on the domain sid and the builtin
sid !
rpc_server/srv_util.c: wrote a new version of get_domain_user_groups().
Only the samr code uses it atm. It uses the group mapping code instead of
a bloody hard coded crap. The netlogon code will use it too, but I have to
do some test first.
J.F.
(This used to be commit 6c87e96149)
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 :-)
Andrew Bartlett
(This used to be commit c95f5aeb93)
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.
Andrew Bartlett
(This used to be commit 762c8758a7)
Currently the only backend which works is smbpasswd (tdb, LDAP, and NIS+)
are broken, but they were somewhat broken before. :)
The following functions implement the storage manipulation interface
/*The following definitions come from passdb/pdb_smbpasswd.c */
BOOL pdb_setsampwent (BOOL update);
void pdb_endsampwent (void);
SAM_ACCOUNT* pdb_getsampwent (void);
SAM_ACCOUNT* pdb_getsampwnam (char *username);
SAM_ACCOUNT* pdb_getsampwuid (uid_t uid);
SAM_ACCOUNT* pdb_getsampwrid (uint32 rid);
BOOL pdb_add_sam_account (SAM_ACCOUNT *sampass);
BOOL pdb_update_sam_account (SAM_ACCOUNT *sampass, BOOL override);
BOOL pdb_delete_sam_account (char* username);
There is also a host of pdb_set..() and pdb_get..() functions for
manipulating SAM_ACCOUNT struct members. Note that the struct
passdb_ops {} has gone away. Also notice that struct smb_passwd
(formally in smb.h) has been moved to passdb/pdb_smbpasswd.c
and is not accessed outisde of static internal functions in this
file. All local password searches should make use of the the SAM_ACCOUNT
struct and the previously mentioned functions.
I'll write some documentation for this later. The next step is to fix
the TDB passdb backend, then work on spliting the backends out into
share libraries, and finally get the LDAP backend going.
What works and may not:
o domain logons from Win9x works
o domain logons from WinNT 4 works
o user and group enumeration
as implemented by Tim works
o file and print access works
o changing password from
Win9x & NT ummm...i'll fix this tonight :)
If I broke anything else, just yell and I'll fix it. I think it
should be fairly quite.

(This used to be commit cfaea90529)
the pre-alpha "domain group" etc parameters have disappeared.
- interactive debug detection
- re-added mem_man (andrew's memory management, detects memory corruption)
- american spellings of "initialise" replaced with english spelling of
"initialise".
- started on "lookup_name()" and "lookup_sid()" functions. proper ones.
- moved lots of functions around. created some modules of commonly used
code. e.g the password file locking code, which is used in groupfile.c
and aliasfile.c and smbpass.c
- moved RID_TYPE_MASK up another bit. this is really unfortunate, but
there is no other "fast" way to identify users from groups from aliases.
i do not believe that this code saves us anything (the multipliers)
and puts us at a disadvantage (reduces the useable rid space).
the designers of NT aren't silly: if they can get away with a user-
interface-speed LsaLookupNames / LsaLookupSids, then so can we. i
spoke with isaac at the cifs conference, the only time for example that
they do a security context check is on file create. certainly not on
individual file reads / writes, which would drastically hit their
performance and ours, too.
- renamed myworkgroup to global_sam_name, amongst other things, when used
in the rpc code. there is also a global_member_name, as we are always
responsible for a SAM database, the scope of which is limited by the role
of the machine (e.g if a member of a workgroup, your SAM is for _local_
logins only, and its name is the name of your server. you even still
have a SID. see LsaQueryInfoPolicy, levels 3 and 5).
- updated functionality of groupname.c to be able to cope with names
like DOMAIN\group and SERVER\alias. used this code to be able to
do aliases as well as groups. this code may actually be better
off being used in username mapping, too.
- created a connect to serverlist function in clientgen.c and used it
in password.c
- initialisation in server.c depends on the role of the server. well,
it does now.
- rpctorture. smbtorture. EXERCISE EXTREME CAUTION.
