If no winbind is around, the best we can do to get the user's token correct is
to ask unix via create_token_from_username. More investigation is needed if
this also fixes the +groupname for unmapped groups problems more cleanly.
Volker
(This used to be commit f6e3ee147f)
what svn is for.
The idea is that we fall back to a pure unix user with S-1-22 SIDs in the
token in case anything weird is going on with the 'force user'.
Volker
(This used to be commit 9ec5ccfe85)
Add missing automatic add of the Administrators SID in the absence
of winbindd and precense of Domain Admins SID in the user's token.
(This used to be commit ce7846d6f1)
Make 2 important changes. pdb_get_methods()
returning NULL is a *fatal* error. Don't try
and cope with it just call smb_panic. This
removes a *lot* of pointless "if (!pdb)" handling
code. Secondly, ensure that if samu_init()
fails we *always* back out of a function. That
way we are never in a situation where the pdb_XXX()
functions need to start with a "if (sampass)"
test - this was just bad design, not defensive
programming.

changing the token generation. I *hate* this code!
Jerry, you have been looking at this as well, can you double-check that I did
not screw it up?
Thanks,
Volker
(This used to be commit 2765c4ff8d)
* Finally fix parsing idmap uid/gid ranges not to break with spaces
surrounding the '-'
* Allow local groups to renamed by adding info level 2 to
_samr_set_aliasinfo()
* Fix parsing bug in _samr_del_dom_alias() reply
* Prevent root from being deleted via Samba
* Prevent builting groups from being renamed or deleted
* Fix bug in pdb_tdb that broke renaming user accounts
* Make sure winbindd is running when trying to create the Administrators
and Users BUILTIN groups automatically from smbd (and not just check the
winbind nexted groups parameter value).
* Have the top level rid allocator verify that the RID it is about to
grant is not already assigned in our own SAM (retries up to 250 times).
This fixes passdb with existing SIDs assigned to users from the RID algorithm
but not monotonically allocating the RIDs from passdb.
(This used to be commit db1162241f)
* Automatically creates the BUILTIN\Users group similar to
how BUILTIN\Administrators is done. This code does need to
be cleaned up considerably. I'll continue to work on this.
* The important fix is for getusergroups() when dealing with a
local user and nested groups. Now I can run the following
successfully:
$ su - jerry -c groups
users BUILTIN\users
(This used to be commit f54d911e68)
group IFF sid_to_gid(S-1-5-32-544) fails and 'winbind nested groups = yes'
* Add a SID domain to the group mapping enumeration passdb call
to fix the checks for local and builtin groups. The SID can be
NULL if you want the old semantics for internal maintenance.
I only updated the tdb group mapping code.
* remove any group mapping from the tdb that have a
gid of -1 for better consistency with pdb_ldap.c.
The fixes the problem with calling add_group_map() in
the tdb code for unmapped groups which might have had
a record present.
* Ensure that we distinguish between groups in the
BUILTIN and local machine domains via getgrnam()
Other wise BUILTIN\Administrators & SERVER\Administrators
would resolve to the same gid.
* Doesn't strip the global_sam_name() from groups in the
local machine's domain (this is required to work with
'winbind default domain' code)
Still todo.
* Fix fallback Administrators membership for root and domain Admins
if nested groups = no or winbindd is not running
* issues with "su - user -c 'groups'" command
* There are a few outstanding issues with BUILTIN\Users that
Windows apparently tends to assume. I worked around this
presently with a manual group mapping but I do not think
this is a good solution. So I'll probably add some similar
as I did for Administrators.
(This used to be commit 612979476a)
fail and we would still return success in the SMBsesssetup reply :-(
* Make sure to create the local token for the server_fino struct
in reply_spnego_kerberos() so that register_vuid() does not fail.
(how did this ever work?)
(This used to be commit 8dafa45b97)
* Fix a couple of related parsing issues.
* in the info3 reply in a samlogon, return the ACB-flags (instead of
returning zero)
Guenther
(This used to be commit 5b89e8bc24)
* ignore the primary group SID attribute from struct samu*
* generate the primary group SID strictlky from the Unix
primary group when dealing with passdb users
* Fix memory leak in original patch caused by failing to free a
talloc *
* add wrapper around samu_set_unix() to prevent exposing the create
BOOL to callers. Wrappers are samu_set_unix() and samu-allic_rid_unix()
(This used to be commit bcf269e2ec)
to make full use of the new talloc() interface. Discussed with Volker
and Jeremy.
* remove the internal mem_ctx and simply use the talloc()
structure as the context.
* replace the internal free_fn() with a talloc_destructor() function
* remove the unnecessary private nested structure
* rename SAM_ACCOUNT to 'struct samu' to indicate the current an
upcoming changes. Groups will most likely be replaced with a
'struct samg' in the future.
Note that there are now passbd API changes. And for the most
part, the wrapper functions remain the same.
While this code has been tested on tdb and ldap based Samba PDC's
as well as Samba member servers, there are probably still
some bugs. The code also needs more testing under valgrind to
ensure it's not leaking memory.
But it's a start......
(This used to be commit 19b7593972)
* remove pdb_context data structure
* set default group for DOMAIN_RID_GUEST user as RID 513 (just
like Windows)
* Allow RID 513 to resolve to always resolve to a name
* Remove auto mapping of guest account primary group given the
previous 2 changes
(This used to be commit 7a2da5f0cc)
talloc_string_sub. Someone with time on his hands could convert all the
callers of all_string_sub to this.
realloc_string_sub is *only* called from within substitute.c, it could be
moved there I think.
Volker
(This used to be commit be6c9012da)
nested group support. Always add the BUILTIN\Administrators
SID to a Domain Admins token.
This solves the extra steps of establishing a group map for
the local Administrators SID in order to control services.
Windows also tends to expect the Administrators group to be
usable when setting up security permissions on shares.
Volker's work will probably fix this long term, but this
gets us past some of the setup hurdles for 3.0.21.
(This used to be commit 170b6a68bc)
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.
Jeremy.
(This used to be commit d1caef8663)
* \PIPE\unixinfo
* winbindd's {group,alias}membership new functions
* winbindd's lookupsids() functionality
* swat (trunk changes to be reverted as per discussion with Deryck)
(This used to be commit 939c3cb5d7)
scripts to be executed.
We were filling in our name as the server which processed the login, even
when it was done by a trusted DC.
Thanks to John Janosik <jpjanosi@us.ibm.com> for the fix.
