Remove some unused code: pdb_find_alias is not used anymore, and nobody I
think has ever used the pdb_nop operations for group mapping. smbpasswd and
tdb use the default ones and ldap has its own.
Make the functions pdb_getgr* return NTSTATUS instead of BOOL. Nobody right
now really makes use of it, but it feels wrong to throw away information so
early.

different directory the temp files should be in, or is /tmp ok?
Still have to get rid of the output file hardcoding, but that is to
come, because I need to cleanup stdout.
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 :-).
Jeremy.
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......
All 'usage' messages are still printed to stdout.
Fix some compiler warnings for system() calls where we didn't used the
return code. Add appropriate error messages and return with the error
code we got from system() or NT_STATUS_UNSUCCESSFUL.
* \PIPE\unixinfo
* winbindd's {group,alias}membership new functions
* winbindd's lookupsids() functionality
* swat (trunk changes to be reverted as per discussion with Deryck)
accounts (accounts without AcctCtrl set) after a vampire-process.
New Accounts tend to hace no acb_info at all which means "0"
(ACB_NORMAL). Unless 0 becomes not 0 we don't do anything and set *no*
acctrl for normal users at all (!). Those crippled users now don't show
up in usrmgr since 3.0.20somethings ldap-routines now finally test if
the attribute is there.

that's my copyright...that's just how we have to do things at big blue.
Adds subcommand to vampire to allow data to be put into an ldif file instead
of actually writing to the passdb. See "net rpc help vampire" for usage
info. This should be added to docs as well.
Does automated migration from account_policy.tdb v1 and v2 and offers a
pdbedit-Migration interface. Jerry, please feel free to revert that if
you have other plans.
