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 used to be commit ff354c99c5)
This moves the rest of the functionality into the 'net rpc join' code.
Futhermore, this moves that entire area over to the libsmb codebase, rather
than the crufty old rpc_client stuff.
I have also fixed up the smbpasswd -a -m bug in the process.
We also have a new 'net rpc changetrustpw' that can be called from a
cron-job to regularly change the trust account password, for sites
that run winbind but not smbd.
With a little more work, we can kill rpc_client from smbd entirly!
(It is mostly the domain auth stuff - which I can rework - and the
spoolss stuff that sombody else will need to look over).

However this looks like the best spot to init the account policy db...
(fix segfaults on all local smbpasswd ops)
Andrew Bartlett
(This used to be commit 3f3bb62ba6)
This kills off the offending code in smbpasswd -j -Uab%c
In the process we have changed from unsing compelatly random passwords
to random, 15 char ascii strings. While this does produce a decrese in
entropy, it is still vastly greater than we need, considering the application.
In the meantime this allows us to actually *type* the machine account
password duruign debugging.
This code also adds a 'check' step to the join, confirming that the
stored password does indeed do somthing of value :-)

more.
(Previously it set them to 'XXXX' or similar when only the flags were being
changed - a bug I must have introduced when I reworked the passdb end of things
a few weeks back.)
Adds a new local flag: LOCAL_SET_PASSWORD to specify that the password is
actually to be changed.
Andrew Bartlett
(This used to be commit cea6b6cb22)
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.

This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.

server manager first. Just use the -U parameter to smbpasswd when joining
the domain:
smbpasswd -r PDC -j DOMAIN -U administrator%password
Should also work with domain users with the 'add workstation to domain'
user right.

source/lib/smbpasswd.c
- Only call load_interfaces() when doing a network related
operation. This means you can add, remove, enable or disable
smbpasswd entries without a network. Changing passwords always
requires a network.
(This used to be commit e2193c3a36)
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.

libsmb/clientgen.c: Fixes for Win2k smbclient browsing.
Other fixes implement smbpasswd -x user to delete users. Also allows swat
to do the same.
Jeremy.
(This used to be commit 9f6ad04676)
done a minimal amout of clean-up in the Makefile, removing unnecessary
modules from the link stage. this is not complete, yet, and will
involve some changes, for example to smbd, to remove dependencies on
the password database API that shouldn't be there. for example,
smbd should not ever call getsmbpwXXX() it should call the Samr or Lsa
API.
this first implementation has minor problems with not reinstantiating
the same services as the caller. the "homes" service is a good example.
(This used to be commit caa5052522)
time out of sending the session setup on Solaris 2.6. No idea.
I'll work on it some tomorrow. This is to fix the "Unable to
setup password vectors" thingy.
Also changed an inet_aton() to inet_addr() as the former is
not very portable :-)
Luke, I set the redir flag to false because the connection to
the smb-agent was failing and smbpasswd bombed. Double check me
on this one.

trusts.

samr_query_aliasmembers (cool!)
util_pwdb.c sids.c nmbd.c server.c smbpasswd.c swat.c :
pwdb_initialise(BOOL is_server) now creates / reads DOMAIN_NAME.SID
if is_server is True, and does LsaQueryInfoPolicy(levels 3 and 5)
to obtain member and pdc sids.
(This used to be commit 3e1eb4f26b)
- split sam_passwd and smb_passwd into separate higher-order function tables
- renamed struct smb_passwd's "smb_user" to "unix_user". added "nt_user"
plus user_rid, and added a "wrap" function in both sam_passwd and smb_passwd
password databases to fill in the blank entries that are not obtained
from whatever password database API instance is being used.
NOTE: whenever a struct smb_passwd or struct sam_passwd is used, it MUST
be initialised with pwdb_sam_init() or pwd_smb_init(), see chgpasswd.c
for the only example outside of the password database APIs i could find.
- added query_useraliases code to rpcclient.
- dealt with some nasty interdependencies involving non-smbd programs
and the password database API. this is still not satisfactorily
resolved completelely, but it's the best i can do for now.
- #ifdef'd out some password database options so that people don't
mistakenly set them unless they recompile to _use_ those options.
lots of debugging done, it's still not finished. the unix/NT uid/gid
and user-rid/group-rid issues are better, but not perfect. the "BUILTIN"
domain is still missing: users cannot be added to "BUILTIN" groups yet,
as we only have an "alias" db API and a "group" db API but not "builtin-alias"
db API...
(This used to be commit 5d5d7e4de7)
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.
(This used to be commit 0d21e1e609)
should allow us to call a function in swat rather than piping to
smbpasswd.
while doing this I also fixed quite a few "const char *" versus "char *" issues
that cropped up while using const to track down bugs in the code. This
led to changes in several generic functions.
The smbpasswd changes should be correct but they have not been
extensively tested. At least if I have introduced bugs then we should
be able to fix them more easily than before.
(This used to be commit 713864dd03)
I did this when I saw yet another bug report complaining about
smbclient intermittently missing files. Rather than applying more
patches to smbclient it was better to move to the more robust
clientgen.c code.
The conversion wasn't perfect, I probably lost some features of
smbclient while doing it, but at least smbclient should be consistent
now. It if fails it should _always_ fail rather than giving people the
false impression of a reliable utility.
the tar stuff seems to work, but hasn't had much testing as I never
use it myself. I'm sure someone will find bugs in my conversion of
smbtar.c. It was quite tricky as it did a lot of its own SMB calls. It
now uses clientgen.c exclusively.
smbclient is still quite messy, but at least it doesn't build its own
SMB packets.
I haven't touched smbmount as I never use it. Mike, do you want to
convert smbmount to use clientgen.c?
