not exactly match what you would expect.
XP workstations during login actually do this, so we should better become a
bit more correct. The LDAP query issued is not really fully optimal, but it is
a lot faster and more correct than what was there before. The change in
passdb.h makes it possible that queryuseraliases is done with a single ldap
query.

I've been grumbling about under-efficient calls in SAMR, and finally
got around to fixing some of them.
We now call sys_getgroups() (which in turn calls initgroups(), until
glibc 3.4 is released) to figure out a user's group membership. This
is far, far more efficient than scanning all the groups looking for a
match, and is still the 'posix way', just using an effiecient call.
The seperate issue of 'who is in this group' remains, but this one has
been biting some people.
I need to talk to VL about how best to exersise nasty corner cases,
but my initial tests hold strong. (The code is also much simpiler
than before, which has to count for something :-)

While machine accounts cannot use an NTLM login (NT4 style), they are
otherwise full and valid members of the domain, and expect to be able to
use kerberos to connect to CIFS servers.
This means that the LocalSystem account, used by various services, can
perform things like backups, without the admin needing to enter further
passwords.
This particular issue (bug 722) has started to come up a lot on the lists.
I have only enabled it for winbindd-based systems, as the macros use use
to call the 'add user script' will strip the $ from the username for
security reasons.

winbind functions to be accessed via NSS. This provides a much cleaner
way for applications that need (for example) to provide name->sid
mappings to do this via NSS rather than having to know the winbindd
pipe protocol (as this might change).
This patch also adds a varient of the winbindd_getgroups() call called
winbindd_getusersids() that provides direct SID->SIDs listing of a
users supplementary groups. This is enough to allow non-Samba
applications to do ACL checking.
A test program for the new functionality will be committed shortly.
I also added the 'wbinfo --user-sids' option to expose the new
function in wbinfo.

* remove idmap_XX_to_XX calls from smbd. Move back to the
the winbind_XXX and local_XXX calls used in 2.2
* all uid/gid allocation must involve winbindd now
* move flags field around in winbindd_request struct
* add WBFLAG_QUERY_ONLY option to winbindd_sid_to_[ug]id()
to prevent automatic allocation for unknown SIDs
* add 'winbind trusted domains only' parameter to force a domain member
server to use matching users names from /etc/passwd for its domain
(needed for domain member of a Samba domain)
* rename 'idmap only' to 'enable rid algorithm' for better clarity
(defaults to "yes")
code has been tested on
* domain member of native mode 2k domain
* ads domain member of native mode 2k domain
* domain member of NT4 domain
* domain member of Samba domain
* Samba PDC running winbindd with trusts
Logons tested using 2k clients and smbclient as domain users
and trusted users. Tested both 'winbind trusted domains only = [yes|no]'

to handle domain trusts. Jeremy and I talked about this
and it's going in as working code. It keeps winbind clean
and solves the trust problem with minimal changes.
To summarize, there are 2 basic cases where the deadlock would
occur. (1) lookuping up secondary groups for a user, and
(2) get[gr|pw]nam() calls that fall through the NSS layer because
they don't exist anywhere.
o To handle case #1, we bypass winbindd in sys_getgrouplist() unless
the username includes the 'winbind separator'.
o Case #2 is handled by adding checks in winbindd to return failure
if we are a DC and the domain matches our own.
This code has been tested using basic share connections, domain
logons, and with pam_winbind (both with and without 'winbind
use default domain'). The 'trustdomain' auth module should work
as well if an admin wants to manually create UNIX users for
acounts in the trusted domains.
Other misc fixes:
* we need to fix check_ntlm_password() to be able to determine
if an auth module is authoritative over a user (NT_STATUS_WRONG_PASSWORD,
etc...). I worked around my specific situation, but this needs to be
fixed. the winbindd auth module was causing delays.
* fix named server mutex deadlock between trust domain auth module
and winbindd looking up a uid
* make sure SAM_ACCOUNT gets stored in the server_info struct for the
_net_sam_logon() reply.
Configuration details:
The recommended method for supporting trusts is to use winbind.
The gets us around some of the server mutex issues as well.
* set 'files winbind' for passwd: and group: in /etc/nsswitch.conf
* create domain trusts like normal
* join winbind on the pdc to the Samba domain using 'net rpc join'
* add normal parameters to smb.conf for winbind
* set 'auth method = guest sam winbind'
* start smbd, nmbd, & winbindd
Problems that remain:
* join a Windows 2k/XP box to a Samba domain.
* create a 2-way trust between the Samba domain
and an NT domain
* logon to the windows client as a user from theh trusted
domain
* try to browse server in the trusted domain (or other
workstations). an NT client seems to work ok, but 2k
and XP either prompt for passwords or fail with errors.
apparanently this never got tested since no one has ever been
able to logon as a trusted user to a Samba domain from a Windows
client.
(This used to be commit f804b590f9dbf1f0147c06a0a2f12e221ae6fc3b)
* move back to qsort() for sorting IP address in get_dc_list()
* remove dc_name_cache in cm_get_dc_name() since it slowed
things down more than it helped. I've made a note of where
to add in the negative connection cache in the ads code.
Will come back to that.
* fix rpcclient to use PRINTER_ALL_ACCESS for set printer (instead
of MAX_ALLOWED)
* only enumerate domain local groups in our domain
* simplify ldap search for seqnum in winbindd's rpc backend
(This used to be commit f8cab8635b02b205b4031279cedd804c1fb22c5b)
* Fix code to use winbind_rpc methods for trusted mixed mode or NT4 domains
( does no one ever test this? )
* add in LDAP code to get the sequence number for rpc based seqnum update.
( this is needed if the DC is upgraded and samba is not reconfigured
to use security = ads; it's not pretty but it works (from app_head) )
* fix bug that caused us to enumerate domain local groups in domains
other than our own

As abartlet rememberd me NT_STATUS_IS_ERR != !NT_STATUS_IS_OK
This patch will cure the problem.
Working on this one I found 16 functions where I think NT_STATUS_IS_ERR() is
used correctly, but I'm not 100% sure, coders should check the use of
NT_STATUS_IS_ERR() in samba is ok now.
Simo.

This replaces the universal group caching code (was originally
based on that code). Only applies to the the RPC code.
One comment: domain local groups don't show up in 'getent group'
that's easy to fix.
Code has been tested against 2k domain but doesn't change anything
with respect to NT4 domains.
netsamlogon caching works pretty much like the universal group
caching code did but has had much more testing and puts winbind
mostly back in sync between branches.
(This used to be commit aac01dc7bc95c20ee21c93f3581e2375d9a894e1)
have a primary ADS domain and a secondary (trusted) NT4 domain. This
caused winbindd to be *really* slow for that setup.
- fixed winbindd_getgrgid(), which was calling uid_to_sid instead of
gid_to_sid(). When you make changes to winbind *PLEASE* test using
nsstest.
(This used to be commit cdd9b60a078b63e22f543d4c8d0956ff536f4d89)
* quit obsessing over the sequence number so much
* share the updated sequence number between parent
and child winbindd processes in dual mode
(This used to be commit 6f99cafa95b2a9dc98d8272fe6a54e9d37098340)
We really need idmap_ldap to have a good solution with ldapsam, porting
it from the prvious code is beeing made, the code is really simple to do
so I am confident it is not a problem to commit this code in.
Not committing it would have been worst.
I really would have been able to finish also the group code, maybe we can
put it into a followin release after 3.0.0 even if it may be an upgrade
problem.
The code has been tested and seem to work right, more testing is needed for
corner cases.
Currently winbind pdc (working only for users and not for groups) is
disabled as I was not able to make a complete group code replacement that
works somewhat in a week (I have a complete patch, but there are bugs)
Simo.
(This used to be commit 0e58085978f984436815114a2ec347cf7899a89d)
This includes the 'SIDs Rule' patch, mimir's trusted domains cacheing code,
the winbind_idmap abstraction (not idmap proper, but the stuff that held up
the winbind LDAP backend in HEAD).
