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.

degree of seperation betwen reading/writing the raw NamedPipe SMB packets
and the matching operations inside smbd's RPC components.
This patch is designed for no change in behaviour, and my tests hold that to be
true. This patch does however allow for the future loadable modules interface
to specify function pointers in replacement of the fixed state.
The pipes_struct has been split into two peices, with smb_np_struct taking the
information that should be generic to where the data ends up.
Some other minor changes are made: we get another small helper function in
util_sock.c and some of the original code has better failure debugs and
variable use. (As per on-list comments).

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).

<a.bokovoy@sam-solutions.net>.
The idea is the domain\username is rather harsh for unix systems - people don't
expect to have to FTP, SSH and (in particular) e-mail with a username like
that.
This 'corrects' that - but is not without its own problems.
As you can see from the changes to files like username.c and wb_client.c (smbd's
winbind client code) a lot of assumptions are made in a lot of places about
lp_winbind_seperator determining a users's status as a domain or local user.
The main change I will shortly be making is to investigate and kill off
winbind_initgroups() - as far as I know it was a workaround for an old bug in
winbind itself (and a bug in RH 5.2) and should no longer be relevent.
I am also going to move to using the 'winbind uid' and 'winbind gid' paramaters
to determine a user/groups's 'local' status, rather than the presence of the
seperator.
As such, this functionality is recommended for servers providing unix services,
but is currently less than optimal for windows clients.
(TODO: remove all references to lp_winbind_seperator() and
lp_winbind_use_default_domain() from smbd)

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.

example of the scope of change the new pstrings would entail:
basically inserting PSTR() or FSTR() everywhere you need to coerce one
to a char*.
It's also a good example of the kind of bug we might catch: on about
line 540, we were doing a pstrcpy into an fstring, which might
overflow. It's not a problem in this particular case, but it is in
general.
