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.

This break local users and 'winbind nested groups' on domain members.
Cannot be helped.
My plans is to move the default domain crud to the client code (pam and
nss libraries) in 3.0.24.

Do not bail out when a group just has 0 members.

* 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

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.

realloc can return NULL in one of two cases - (1) the realloc failed,
(2) realloc succeeded but the new size requested was zero, in which
case this is identical to a free() call.
The error paths dealing with these two cases should be different,
but mostly weren't. Secondly the standard idiom for dealing with
realloc when you know the new size is non-zero is the following :
tmp = realloc(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
However, there were *many* *many* places in Samba where we were
using the old (broken) idiom of :
p = realloc(p, size)
if (!p) {
return error;
}
which will leak the memory pointed to by p on realloc fail.
This commit (hopefully) fixes all these cases by moving to
a standard idiom of :
p = SMB_REALLOC(p, size)
if (!p) {
return error;
}
Where if the realloc returns null due to the realloc failing
or size == 0 we *guarentee* that the storage pointed to by p
has been freed. This allows me to remove a lot of code that
was dealing with the standard (more verbose) method that required
a tmp pointer. This is almost always what you want. When a
realloc fails you never usually want the old memory, you
want to free it and get into your error processing asap.
For the 11 remaining cases where we really do need to keep the
old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR,
which can be used as follows :
tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size);
if (!tmp) {
SAFE_FREE(p);
return error;
} else {
p = tmp;
}
SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the
pointer p, even on size == 0 or realloc fail. All this is
done by a hidden extra argument to Realloc(), BOOL free_old_on_error
which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR
macros (and their array counterparts).
It remains to be seen what this will do to our Coverity bug count :-).

Fix parse_domain_user to fail when splitting a full name like "DOM\user"
when "winbind use default domain" and "winbind trusted domains only" are
not enabled.
This allows pam_winbind to behave correctly when more modules are
stacked in the "account" or "password" PAM facility. pam_winbindd calls
WINBINDD_GETPWNAM which can decide whether or not a user is a winbind
user and return correct PAM error codes.

of the
parent winbind not to return winbindd_result. This is to hopefully fix all the
problems where a result has been scheduled for write twice.
The problematic ones have been the functions that might have been delayed as
well as under other circumstances immediately gets answered from the cache.
Now a request needs to be explicitly replied to with a request_error() or
request_ok().

implementation does
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 :-)
