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 :-).

This allow the user to select
'passdb backend = plugin : /path/to/plugin.so : pluging args'
And load any arbitary plugin. Apparently Jelmer has a mysql plugin in the
works - hence this patch.
We probably need to rework the interface a bit before 3.0 (add versioning of
some kind) but this is a good start.

There are still differences in the local_password_change function. I'm
not sure which was the latest so I didn't change any thing else. Someone
needs to take a look and sync these up.

- 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).

Modules now name themselves, which should allow for sane behaviour when we get
an 'extern' passdb module (which in turn loads a .so).

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.

Anyway, this makes it slightly sane, but we may decide to smb_panic() here
instead.

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.

jerry, can you look at theis where we use standard_sub_advanced() fns?
I think this structure should be backported to 2.2 because we do not know if the SAM_ACCOUNT strings have enough space to contain the "substituted" string.
(Yes, just now we know they are pstrings, but we may change them into alloced one, I'm a strong suported of alloced strings as 1024 bytes are not always enough and are often too much)
