Patch details:
Support most options in pam_winbind.conf; support comma-separated names in
require-membership-of. Details below:
1) Provides support for almost all config options in pam_winbind.conf
(all except for use_first_pass, use_authtok, and unknown_ok).
- That allows us to work well when invoked via call_modules from
pam_unix2.conf as well as allowing use of spaces in names used
w/require_membership_of.
2) Support for comma-separated list of names or SID strings in
require_membership_of/require-membership-of.
- Increased require_membership_of field in winbind request from fstring
(256) to pstring (1024).
- In PAM side, parse out multiple names or SID strings and convert
all of them to SID strings.
- In Winbind side, support membership check against multiple SID strings.

This allows a provider to supply the homedirectory, etc...
attributes for a user without requiring support in core
winbindd code. The idmap_ad.c module has been modified
to provide the idmap 'ad' library as well as the rfc2307 and sfu
"winbind nss info" support.
The SID/id mapping is working in idmap_ad but the nss_info
still has a few quirks that I'm in the process of resolving.

this at the moment as I'm working on this area. Thanks
a lot Guenther.
Add the capability to get krb5 tickets even if we
log on in the offline state and have to cache
the credentials. Once we go online we should
start getting krb5 tickets again. Currently
this code waits until lp_winbind_cache_time()
seconds (5 minutes by default) before getting
tickets. This is correct in the DC down case,
but not in the global offline -> online case.
I'll later add a trigger to force an immediate refresh
on the offline -> online state transition.

krb5 refresh creds when doing cached NTLM auth, request
the memory creds instead.
Jeremy.
(This used to be commit 310ac0b226edcfd5bedc2c3305a05993db20c7af)
from the krb5 ticket renewal code. This allows cached
credentials to be stored for single sign-on via ntlm_auth
for machines in a domain still using NTLM. Also (hopefully)
fixes the reference counting problem with pam_logon/logoff
so multiple logons/logoffs won't lose cached credentials.
This compiles, but I'm intending to test it over the weekend
so don't complain too much :-). I also want it in the tree
so Coverity can scan it for errors. Guenther, check this over
please - I ran through the architecture with Jerry and he's
ok with it, but this is modifying your code a lot.

stored - only store the password if we're going to
be doing a krb5 refresh. GD please review this change !
Now to add code to reference count the cached creds
(to allow multiple pam_logon/pam_logoffs to keep the
creds around), ensure that the cred cache is called
on all successful pam_logons (if we have winbindd cache
pam credentials = true, set this by default) and finally
ensure the creds cache is changed on successful password
change. GD - you *really* need to review this :-).
Jeremy.

ntlm_auth module to allow it to use winbindd cached
credentials.The credentials are currently only stored
in a krb5 MIT environment - we need to add an option to
winbindd to allow passwords to be stored even in an NTLM-only
environment.

(This used to be commit ae7cc298a113d8984557684bd6ad216cbb27cff3)
This patch add some missing async functions to
solve UID/GID -> SID requests not just out of the cache,
but down the remote idmap if necessary.
This patch solves the problem of servers not showing users/groups names
for allocated UID/GIDs when joined to a group of servers that share a
prepopulated idmap backend.
Also correctly resolve UID/GIDs to SIDs when looking ACLs from the
windows security tab on teh same situation.
Simo.

NO NOT change the winbindd response or request structures
*unless* you test a 32bit wbinfo against a 64bit winbindd.
The structure sizes MUST be the same on 32bit and 64 bit
platforms.
The way to test is to build a 64bit version of Winbind as normal.
Then build a 32bit version using gcc -m32. Now install the 64bit and
32bit versions of libnss_winbindd.so and launch the 64bit winbindd.
Make sure that the responses from both 32bit and 64bit versions
of wbinfo match.
If you don't understand the previous paragraph you don't need to
be changing nsswitch/winbindd_nss.h

This mode proxies pre-calculated blobs from a remote (probably VPN)
client into the domain. This allows clients to change their password
over a PPTP connection (where they would not be able to connect to
SAMR directly).
The precalculated blobs do not reveal the plaintext password.

logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT
or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes
the auth module interface to 2 (from 1). The effect of this is
that clients can access resources as a machine account if they
set these flags. This is the same as Windows (think of a VPN
where the vpn client authenticates itself to a VPN server
using machine account credentials - the vpn server checks
that the machine password was valid by performing a machine
account check with the PDC in the same was as it would a
user account check. I may add in a restriction (parameter)
to allow this behaviour to be turned off (as it was previously).
That may be on by default.
Andrew Bartlett please review this change carefully.

homedirectory and the loginshell from Active Directory's "Services for Unix".
Enable it with:
winbind sfu support = yes
User-Accounts without SFU-Unix-Attributes will be assigned template-based
Shells and Homedirs as before.
Note that it doesn't matter which version of Services for Unix you use (2.0,
2.2, 3.0 or 3.5). Samba should detect the correct attributes (msSFULoginShell,
msSFU30LoginShell, etc.) automatically.
If you also want to share the same uid/gid-space as SFU then also use PADL's
ad-idmap-Plugin:
idmap backend = ad
When using the idmap-plugin only those accounts will appear in Name Service
Switch that have those UNIX-attributes which avoids potential uid/gid-space
clashes between SFU-ids and automatically assigned idmap-ids.

1. using smbc_getxattr() et al, one may now request all access control
entities in the ACL without getting all other NT attributes.
2. added the ability to exclude specified attributes from the result set
provided by smbc_getxattr() et al, when requesting all attributes,
all NT attributes, or all DOS attributes.
3. eliminated all compiler warnings, including when --enable-developer
compiler flags are in use. removed -Wcast-qual flag from list, as that
is specifically to force warnings in the case of casting away qualifiers.
Note: In the process of eliminating compiler warnings, a few nasties were
discovered. In the file libads/sasl.c, PRIVATE kerberos interfaces
are being used; and in libsmb/clikrb5.c, both PRIAVE and DEPRECATED
kerberos interfaces are being used. Someone who knows kerberos
should look at these and determine if there is an alternate method
of accomplishing the task.
(This used to be commit 994694f7f26da5099f071e1381271a70407f33bb)
whole of samba comiles warning-free with the default compiler flags.
Temporarily defined -Wall to locate other potential problems. Found an
unused static function (#ifdefed out rather than deleted, in case it's
needed for something in progress).
There are also a number of uses of undeclared functions, mostly krb5_*.
Files with these problems need to have appropriate header files included,
but they are not fixed in this update.
oplock_linux.c.c has undefined functions capget() and capset(), which need
to have "#undef _POSIX_SOURCE" specified before including <sys/capability.h>,
but that could potentially have other side effects, so that remains uncorrected
as well.
The flag -Wall should be added permanently to CFLAGS, and all warnings then
generated should be eliminated.

domains, this patch ensures that we always use the ADS backend when
security=ADS, and the remote server is capable.
The routines used for this behaviour have been upgraded to modern Samba
codeing standards.
This is a change in behaviour for mixed mode domains, and if the trusted
domain cannot be reached with our current krb5.conf file, we will show
that domain as disconnected.
This is in line with existing behaviour for native mode domains, and for
our primary domain.
As a consequence of testing this patch, I found that our kerberos error
handling was well below par - we would often throw away useful error
values. These changes move more routines to ADS_STATUS to return
kerberos errors.
Also found when valgrinding the setup, fix a few memory leaks.
While sniffing the resultant connections, I noticed we would query our
list of trusted domains twice - so I have reworked some of the code to
avoid that.

Instead of returning a name in DOMAIN\user format, we now return it in the
same way that nsswtich does - following the rules of 'winbind use default
domain', in the correct case and with the correct seperator.
This should help sites who are using Squid or the new SASL code I'm working
on, to match back to their unix usernames.

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.

* move rid allocation into IDMAP. See comments in _api_samr_create_user()
* add winbind delete user/group functions
I'm checking this in to sync up with everyone. But I'm going to split
the add a separate winbindd_allocate_rid() function for systems
that have an 'add user script' but need idmap to give them a RID.
Life would be so much simplier without 'enable rid algorithm'.
The current RID allocation is horrible due to this one fact.
Tested idmap_tdb but not idmap_ldap yet. Will do that tomorrow.
Nothing has changed in the way a samba domain is represented, stored,
or search in the directory so things should be ok with previous installations.
going to bed now.
(This used to be commit 0463045cc7ff177fab44b25faffad5bf7140244d)
* 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]'
This will be a long week of changes. The next item on the list is
winbindd_passdb.c & machine trust accounts not in /etc/passwd (done
via winbindd_passdb)
