...hmmm... completely bogus. This does not affect us as a domain controller,
as we never set other_sids, but I have *no* idea how winbind got away with it.
Please review thoroughly, samba4 idl looks closer to reality here.
Test case: Member of w2k3 domain, authenticate as a user who is member of one
or more domain local groups. Easiest review with 'client schannel = no'.
Thanks,

(based on Simo's code in trunk). Rewritten with the
following changes:
* privilege set is based on a 32-bit mask instead of strings
(plans are to extend this to a 64 or 128-bit mask before
the next 3.0.11preX release).
* Remove the privilege code from the passdb API
(replication to come later)
* Only support the minimum amount of privileges that make
sense.
* Rewrite the domain join checks to use the SeMachineAccountPrivilege
instead of the 'is a member of "Domain Admins"?' check that started
all this.
Still todo:
* Utilize the SePrintOperatorPrivilege in addition to the 'printer admin'
parameter
* Utilize the SeAddUserPrivilege for adding users and groups
* Fix some of the hard coded _lsa_*() calls
* Start work on enough of SAM replication to get privileges from one
Samba DC to another.
* Come up with some management tool for manipultaing privileges
instead of user manager since it is buggy when run on a 2k client
(haven't tried xp). Works ok on NT4.
set the value "forcibly disconnect remote users from server when logon
hours expire" to "no", instead take the value from our account-policy
storage.

based on samba4-idl.
This saves us an enormous amount of totally unnecessary ldap-traffic
when several hundreds of winbind-daemons query a Samba3 DC just to get
the fake SAM-sequence-number (time(NULL)) by enumerating all users, all
groups and all aliases when query-dom-info level 2 is used.
Note that we apparently never get the sequence number right (we parse a
uint32, although it's a uint64, at least in samba4 idl). For the time
being, I would propose to stay with that behaviour.

The old #ifdef JRATEST-block was copying 16 bytes and thus overwriting
acct_flags with bizarre values, breaking a lot of things.
This patch is successfully running in a production environment for quite
some time now and is required to finally allow Exchange 5.5 to access
another Exchange Server when both are running on NT4 in a
samba-controlled domain. This also allows Exchange Replication to take
place, Exchange Administrator to access other Servers in the network,
etc. Fixes Bugzilla #1136.
Thanks abartlet for helping me with that one.

comment string and not an unknown 12 byte structure...
Found after abartlet's smbtorture extended this string to
"Tortured by Samba4: Fri Nov 26 15:40:18 2004 CET"
;-))

the publishing-state for migrated printers as well.
Therefor added client-side-support for setprinter level 7.
Next will be a "net rpc printer publish"-command (just for completeness).
Guenther
* add IA64 to the architecture table of printer-drivers
* add new "net"-subcommands:
net rpc printer migrate {drivers|printers|forms|security|settings|all}
[printer]
net rpc share migrate {shares|files|all} [share]
this is the first part of the migration suite. this will will (once
feature-complete) allow to do 1:1 server-cloning in the best possible way by
making heavy use of samba's rpc_client-functions. all migration-steps
are implemented as rpc/smb-client-calls; net communicates via rpc/smb
with two servers at the same time (a remote, source server and a
destination server that currently defaults to the local smbd). this
allows e. g. printer-driver migration including driverfiles, recursive
mirroring of file-shares including file-acls, etc. almost any migration
step can be called with a migrate-subcommand to provide more flexibility
during a migration process (at the cost of quite some redundancy :) ).
"net rpc printer migrate settings" is still in a bad condition (many
open questions that hopefully can be adressed soon).
"net rpc share migrate security" as an isolated call to just migrate
share-ACLs will be added later.
Before playing with it, make sure to use a test-server. Migration is a
serious business and this tool-set can perfectly overwrite your
existing file/print-shares.
* along with the migration functions had to make I the following
changes:
- implement setprinter level 3 client-side
- implement net_add_share level 502 client-side
- allow security descriptor to be set in setprinterdata level 2
serverside

On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork().
For other systems, we now only re-seed after a fork, and on startup.
No need to do it per-operation. This removes the 'need_reseed'
parameter from generate_random_buffer().

was 'rpcclient -c "enumprinters 2"' with 4000 printers. At some point this
completely exploded in memory usage. For every string we talloc'ed memory up
to the end of the buffer. -> O(n^2).
This survives valgrind with this number of printers. It might also have
influence on winbind with a large number of users.
All those who dare to look at samba3 rpc code, could you please take a look? I
know this is a burden, but I would like comments ;-)))

for setting up an schannel connection. This solves the problem
of a Samba DC running winbind, trusting a native mode AD domain,
and needing to enumerate AD users via wbinfo -u.
* force the PRINTER_ATTRIBUTE_LOCAL (nor PRINTER_ATTRIBUTE_NETWORK)
* ensure that we return the sec_desc in smb_io_printer_info_2
(allows prnui.dll to restore security descriptors from a data file).
group_info4 in set_dom_group_info also has the level in the record
itself. This seems not to be an align. Tested with NT4 usrmgr.exe. It can
still create a domain group on a samba machine.

in lib/smbpasswd.c that were exact duplicates of functions in passdb/passdb.c
(These should perhaps be pulled back out to smbpasswd.c, but that can occour
later).
Andrew Bartlett
As well as avoiding DOS charset issues, this scheme returns useful error
codes, that we can map back via the pam interface.
This patch also cleans up the interfaces used for password buffers, to
avoid duplication of code.
