If the range allows it, then id==0 should not be forbidden.
This seems to have been taken in from idmap_ldap when the
function was originally created.
See 634cd2e045 .
The other backends don't seem to have had that
extra check for id == 0.
The reasoning for this change is that the range check should
apply to all cases. If the range includes the 0, then it
should be possible to get it as result. In particular,
this way, the function becomes applicable also to the
passdb backend case, e.g. in a samba4-ad-dc setup where
the Admin gets uid == 0.

The sign of the uid_t type is left unspecified by POSIX. It's defined as
an unsigned 32b int on Linux, therefore the < 0 check is always
false.
For unsigned version of uid_t, "uid == -1" will implicitely cast -1 to
unsigned making it a valid test for both signed and unsigned version of
uid_t.
This commit makes the cast to (uid_t) explicit anyway.

When doing a SID to xid mapping for an unknown SID, the idmap child gets
passed a lsa_RefDomainList with an empty domain name (ie ""). This is
coming from LsaLookupSids() and causes the mapping request to end up in
the default idmap domain.
Example request with domain name "":
wbint_Sids2UnixIDs: struct wbint_Sids2UnixIDs
in: struct wbint_Sids2UnixIDs
domains : *
domains: struct lsa_RefDomainList
count : 0x00000001 (1)
domains : *
domains: ARRAY(1)
domains: struct lsa_DomainInfo
name: struct lsa_StringLarge
length : 0x0000 (0)
size : 0x0002 (2)
string : *
string : ''
sid : *
sid : S-1-5-21-3152989960-574718769-2188965058
max_size : 0x00000020 (32)
ids : *
ids: struct wbint_TransIDArray
num_ids : 0x00000001 (1)
ids: ARRAY(1)
ids: struct wbint_TransID
type : ID_TYPE_NOT_SPECIFIED (0)
domain_index : 0x00000000 (0)
rid : 0x000029aa (66666)
xid: struct unixid
id : 0xffffffff (4294967295)
type : ID_TYPE_NOT_SPECIFIED (0)
In _wbint_Sids2UnixIDs() we call idmap_find_domain_with_sid() with the
domain name "" and this triggers use of the default idmap domain which
in case of idmap_autorid will allocate an id from a idmap_autorid range.
If we know the domain, ensure we return it for SIDs were the SID was not
found but the domain of the SID was found. Callers like sids2xids depend
on the domain name and returning an empty string "" for valid domain can
trigger unwanted idmap range allocations.

The idmap_ad child is designed to connect to domain controllers on
its own. Finding a DC is a nontrivial task that the child should not
do on its own, in particular it should not have to connect to "our"
DC's NETLOGON pipe separately. So when idmap_ad finds that it needs to
connect to a DC, it returns NT_STATUS_DOMAIN_CONTROLLER_NOT_FOUND. The
parent then asynchronously does the lookup and stores the DC info in
gencache. After that the parent re-does the idmap child call, during
which the child will find the DC-info in gencache.

The nss functions technically right now are part of the idmap modules. However,
there is no intrinsic reason for this mixture of concerns. I would like to

functions (yet!!). So as a first step this patch moves the nss functions
textually out of the way.

We don't need to change the protocol version because:
1. An old client may provide the "initial_blob"
(which was and is still ignored when going
via the wbcCredentialCache() function)
and the new winbindd won't use new_spnego.
2. A new client will just get a zero byte
from an old winbindd. As it uses talloc_zero() to
create struct winbindd_response.
3. Changing the version number would introduce problems
with backports to older Samba versions.
New clients which are capable of using the new_spnego field
will use "negotiate_blob" instead of "initial_blob".

This prepares the equivalent of 2b1dd01934 for xids2sids.
Collecting sids2xids per domain is a bit easier: SIDs carry their own domain
prefix. For the reverse, we need to scan the configuration for all the idmap
range definitions.
It has a separate effect: It enables overlapping idmap ranges. The per-domain
calls are done whenever a range matches. If the idmap child finds a successful
xid2sid mapping, this will be collected as one result. This means that every
range definition can contribute mappings.
If there are two rfc2307 sfu domains with overlapping ranges, the domains will
be queried one after the other for a specific mapping. If the defined ranges
overlap, the admin has to make sure that there are no conflicts, because in the
current code "the first writer wins", and the code does not specify an order
(yet).
