This moves it right into the passdb subsystem, where we can do this in
just one (or 2) places. Due to the fact that this code can be in a tight loop,
I've had to make 'guest account' a 'const' paramater, where % macros cannot be
used. In any case, if the 'guest account' varies, we are in for some nasty
cases in the other code, so it's useful anyway.

- That we never call winbind recursivly
- That we never use an 'algorithmic' RID when we have a fixed uid or gid mapping
in either the passdb or the group mapping db.
Also, remove restrictions that say 'this domain only'. If we have a mapping
configured, allow it to be returned. If we later decide certian mappings are
invalid, then we sould put that in the code that actually does the map.
Allow 'sid->name' transtations on the fixed 'well known' groups for NT, even
if they are not represented by Unix groups yet.

*.o) and implment new enum_dom_users code in the SAMR RPC subsystem.
Incresingly, we are using the pdb_get_{user,group}_sid() functions, in the
eventual hope that we might one day support muliple domains off a single
passdb. To extract the RID, we use sid_peek_check_rid(), and supply an
'expected' domain SID.
The id21 -> SAM_ACCOUNT and id23 -> SAM_ACCOUNT code has been moved to
srv_samr_util.c, to ease linking in passdb users.
Compatiblity code that uses 'get_global_sam_sid()' for the 'expected' sid is in
pdb_compat.c

rather than a string when configuring mulitple backends.
Also adjust some of the users of get_global_sam_sid() to cope with the fact
that it just might not exist (uninitialised, can't access secrets.tdb).
More places need conversion.
Add some const and remove silly casts.

to using SIDs instead of RIDs.
The new funciton sid_peek_check_rid() takes an 'expected domain sid' argument.
The idea here is to prevent mistakes where the SID is implict, but isn't
the same one that we have in the struct.

passdb interface change, now the passdb modules will be asked for SID not for rid, the modules have been updated with a passthrough function that calls the old getsampwrid() functions.
srv_samr_nt.c functions that made use of the pdb_getsampwrid funcion has been updated to use the SID one.

this is a first step only passdb stuff has beein "classized".
- so what can you do?
set debug level to: 1 poasdb:10
that will make all the code run at debug level 1 except the code in
passdb/* files that will run at level 10
TODO: fix the man page
- also smbcontrol has this nice feature so smbcontrol smbd debug 3 passdb:5
will set every smbd to have a default log level of 3 while passdb stuff
will be at level 5
and so no..
minor cosmetic fix to pdbedit is there too

cleanup some of the code in net_rpc_join re const warnings and
fstrings.
Passdb:
Make the %u and %U substituions in passdb work.
This is done by declaring these paramters to be 'const' and doing
the substitution manually. I'm told this is us going full circle,
but I can't really see a better way.
Finally these things actually seem to work properly...
Make the lanman code use the pdb's recorded values for homedir etc
rather than the values from lp_*()
Add code to set the plaintext password in the passdb, where it can
decide how to store/set it. For use with a future 'ldap password
change' option, or somthing like that...
Add pdb_unix, so as to remove the 'not in passdb' special cases from the
local_lookup_*() code. Quite small, as it uses the new 'struct passwd ->
SAM_ACCOUNT' code that is now in just one place. (also used by pdb_smbpasswd)
Other:
Fix up the adding of [homes] at session setup time to actually pass
the right string, that is the unix homedir, not the UNC path.
Fix up [homes] so that for winbind users is picks the correct name.
(bad interactions with the default domain code previously)
Change the rpc_server/srv_lsa_nt.c code to match NT when for the
SATUS_NONE_MAPPED reply: This was only being triggered on
no queries, now it is on the 'no mappings' (ie all mappings failed).
Checked against Win2k.
Policy Question: Should SID -> unix_user.234/unix_group.364 be
considered a mapping or not? Currently it isn't.

All uids and gids must create valid RIDs, becouse other code expects this, and
can't handle the failure case. (ACL code in particular)
Allow admins to adjust the base of the RID algorithm, so avoid clashes with
users brought in from NT (for example).
Put all the algorithm code back in one place, so that this change is global.
Better coping with NULL sid pointers - but it still breaks a lot of stuff.
BONUS: manpage entry for new paramater :-)
counter based rids for normal users in tdbsam is disabled for the timebeing,
idra and I will work out some things here soon I hope.

the passdb) and RIDs not in the passdb, due to being NIS users etc.
The main fix here is to add become_root()/unbecome_root() at critical places.
This (finally) fixes the bug where you could not see local users's names
in a file's security properties as non-root. Tested.
The similar bug in uid_to_sid is also fixed, but is not (yet) Tested.

The main change here is to move ldap into the new pluggable passdb subsystem
and to take the LDAP location as a 'location' paramter on the 'passdb backend'
line in the smb.conf. This is an LDAP URL, parsed by OpenLDAP where supported,
and by hand where it isn't.
It also adds the ldap user suffix and ldap machine suffix smb.conf options,
so that machines added to the LDAP dir don't get mixed in with people.
Non-unix account support is also added. This means that machines don't need to
be in /etc/passwd or in nss_ldap's scope.
This code has stood up well under my production environment, so it relitivly
well tested.
I'm commiting this now becouse others have shown interest in using it, and
there is no point 'hording' the code :-).

- Rework the name -> sid lookup function to always try local lookup first (for
local domain names) before trying winbind. This seems to eliminate my winbind
feedback loop problems. (I don't use winbind for nsswitch, where there are
almost certainly further issues).

Samba now features a pluggable passdb interface, along the same lines as the
one in use in the auth subsystem. In this case, only one backend may be active
at a time by the 'normal' interface, and only one backend per passdb_context is
permitted outside that.
This pluggable interface is designed to allow any number of passdb backends to
be compiled in, with the selection at runtime. The 'passdb backend' paramater
has been created (and documented!) to support this.
As such, configure has been modfied to allow (for example) --with-ldap and the
old smbpasswd to be selected at the same time.
This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua.
These two backends accept 'non unix accounts', where the user does *not* exist
in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to
avoid conflicts in the algroitmic mapping of RIDs, they use the values
specified in the 'non unix account range' paramter - in the same way as the
winbind ranges are specifed.
While I was at it, I cleaned up some of the code in pdb_tdb (code copied
directly from smbpasswd and not really considered properly). Most of this was
to do with % macro expansion on stored data. It isn't easy to get the macros
into the tdb, and the first password change will 'expand' them. tdbsam needs
to use a similar system to pdb_ldap in this regard.
This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I
don't have the test facilities for these. I plan to incoroprate at least
pdb_ldap into this scheme after consultation with Jerry.
Each (converted) passdb module now no longer has any 'static' variables, and
only exports 1 init function outside its .c file.
The non-unix-account support in this patch has been proven! It is now possible
to join a win2k machine to a Samba PDC without an account in /etc/passwd!
Other changes:
Minor interface adjustments:
pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*.
pdb_update_sam_account() no longer takes the 'override' argument that was being
ignored so often (every other passdb backend). Extra checks have been added in
some places.
Minor code changes:
smbpasswd no longer attempts to initialise the passdb at startup, this is
now done on first use.
pdbedit has lost some of its 'machine account' logic, as this behaviour is now
controlled by the passdb subsystem directly.
The samr subsystem no longer calls 'local password change', but does the pdb
interactions directly. This allow the ACB_ flags specifed to be transferred
direct to the backend, without interference.
Doco:
I've updated the doco to reflect some of the changes, and removed some paramters
no longer applicable to HEAD.

This time its the pdb_getsampwuid() function - which was only being used by the
SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is
actually generated at login time, and the other changes here simply move that
data around.
This also means that (when I check some details) we will be able to use the
user session key, even when we are not actually the DC, becouse its one of the
components of the info3 struct returned on logon.

conversion across to the pdb_set...() interface.
Now we only set strings that are non-null. This allows Win2k to join the
domain again, particularly when using tdbsam.

Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps
them around for a long time - often past the next call...
This adds a getpwnam_alloc and a getpwuid_alloc to the collection.
These function as expected, returning a malloced structure that can be
free()ed with passwd_free(&passwd).
This patch also cuts down on the number of calls to getpwnam - mostly by
taking advantage of the fact that the passdb interface is already
case-insensiteve.
With this patch most of the recursive cases have been removed (that I know
of) and the problems are reduced further by not using the sys_ interface
in the new code. This means that pointers to the cache won't be affected.
(This is a tempoary HACK, I intend to kill the password cache entirly).
The only change I'm a little worried about is the change to
rpc_server/srv_samr_nt.c for private groups. In this case we are getting
groups from the new group mapping DB. Do we still need to check for private
groups? I've toned down the check to a case sensitve match with the new code,
but we might be able to kill it entirly.
I've also added a make_modifyable_passwd() function, that copies a passwd
struct into the form that the old sys_getpw* code provided. As far as I can
tell this is only actually used in the pass_check.c crazies, where I moved
the final 'special case' for shadow passwords (out of _Get_Pwnam()).
The matching case for getpwent() is dealt with already, in lib/util_getent.c
Also included in here is a small change to register the [homes] share at vuid
creation rather than just in one varient of the session setup. (This picks
up the SPNEGO cases). The home directory is now stored on the vuid, and I
am hoping this might provide a saner way to do %H substitions.
TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change
the remaining sys_getpwnam() callers to use getpwnam_alloc() and move
Get_Pwnam to return an allocated struct.

Also set the default value of all the allocated strings to "" to avoid changing
the interface (becouse pdb_get...() would point to a null string, rather than a
null pointer and parts of samba rely on that).

These strings are allocated using talloc(), either using its own memory context
stored on the SAM_ACCOUNT or one supplied by the caller.
The pdb_init_sam() and pdb_free_sam() function have been modifed so that a call
to pdb_free_sam() will either clean up (remove hashes from memory) and destroy
the TALLOC_CTX or just clean up depending on who supplied it.
The pdb_init_sam and pdb_free_sam functions now also return an NTSTATUS, and I
have modified the 3 places that actually checked these returns.
The only nasty thing about this patch is the small measure needed to maintin
interface compatability - strings set to NULL are actually set to "".
This is becouse there are too many places in Samba that do strlen() on these
strings without checking if they are NULL pointers.
A supp patch will follow to set all strings to "" in pdb_default_sam().

people start doing using strlen(src) in strncpy() :-)
This occured when the talloc based passdb was reverted in favor of a pstring
based one. In the talloc version this was fine, becouse the buffer was
strlen(src) bytes long. This no longer applies...
This doesn't seem to have broken anything, but I'm chasing up an oddity with NT
password changing from the last merge.

Thou shalt not reference SAM_ACCOUNT members directly - always use
pdb_get/pdb_set.
This is achived by making the whole of SAM_ACCOUNT have a .private member,
where the real members live. This caught a pile of examples, and these have
beeen fixed.
The pdb_get..() functions are 'const' (have been for some time) and this
required a few small changes to constify other functions.
I've also added some debugs to the pdb get and set, they can be removed if
requested.
I've rewritten the copy_id2x_to_sam_pass() functions to use the new passdb
interface, but I need the flags info to do it properly.
The pdb_free_sam() funciton now blanks out the LM and NT hashes, and as such
I have removed many extra 'samr_clear_sam_passwd(smbpass)' calls as a result.
Finally, any and all testing is always appriciated - but the basics seem to
work.

members (such as uid and gid). This way we will be able to
keep ourselves from writing out default smb.conf settings when
the admin doesn't want to, That part is not done yet.
Tested compiles with ldap/tdb/smbpasswd. Tested connection with smbpasswd
backend.
oh...and smbpasswd doesn'y automatically expire accounts after 21 days
from the last password change either now. Just ifdef'd out that code
in build_sam_account().
Will merge updates into 2.2 as they are necessary.

- 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.

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.

You can change them with either usermanager->policies->account
or from a command prompt on NT/W2K: net accounts /domain
we can add a rpc accounts to the net command. As the net_rpc.c is still
empty, I did not start. How should I add command to it ? Should I take the
rpcclient/cmd_xxx functions and call them from there ?

This time it's a PRIVILEGE_SET struct instead of a simple uint32 array. It
makes much more sense. Also added a uint32 systemaccount to the GROUP_MAP
struct as some privilege showing in USRMGR.EXE are not real privs but a
bitmask flag. I guess it's an heritage from NT 3.0 ! I could setup an NT
3.1 box to verify, but I'm too lazy (yes I still have my CDs).
Added 3 more LSA calls: SetSystemAccount, AddPrivileges and
RemovePrivileges, we can manage all this privilege from UserManager.
Time to change the NT_USER_TOKEN struct and add checks in all the rpc

structre contains pointers (well not if you intend of free those pointers
at some stage)
There is no reason (given the new passdb interface) that you can't modify a
SAM_ACCOUNT in any case.
