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 :-).

same reason as per pdb_tdb.c
there isn't (and will never be probably) another call to any getpw* fn,
let's use getpwnam_alloc only when needed.

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.

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.

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.

cli_reg.c - indentation
pdb_ldap.c - some checks on init fns parameters
pdb_tdb.c - some checks on init fns parameters + make sure we close the db on failure

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.

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.

Zero out some of the plaintext passwords for paranoia
Fix up some of the other passdb backends with the change to *uid_t rather than
uid_t.
Make some of the code in srv_netlog_nt.c clearer, is passing an array around,
so pass its lenght in is definition, not as a seperate paramater.
Use sizeof() rather than magic numbers, it makes things easier to read.
Cope with a PAM authenticated user who is not in /etc/passwd - currently by
saying NO_SUCH_USER, but this can change in future.

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 :-)
