cff1924130 idmap_ad: Restore querying SFU nss info
With the last commit the getpwsid call did not look at the winbind
nss info parameter anymore. This restores it for the idmap ad backend
with slightly different semantics and configuration: We now have the
unix_primary_group and unix_nss_info domain-specific parameters for
idmap config. This enables overriding the Windows primary group with
the unix one.

bce19a6efe winbind: Restructure wb_getpwsid
This patch moves the responsibility to create a winbind user from the
winbind backends into wb_queryuser.c. The name comes from lsa_lookupsids,
the uid from idmap. If we have a netsamlogon_cache, we get the primary
group sid from there. Without netsamlogon_cache, we default to -513, as
we do right now as default for non-reachable ADS domains anyway. Shell
and homedir default to template. This can all be done in the parent
without contacting any LDAP-related calls and is correct once we have
a netsamlogon_cache.

Once the parent has filled in the userinfo, the idmap child is queried
with the GetNssInfo call, taking the userinfo [in,out]. The child is
free to override the whole thing, something the AD backend will do in
the next patch.

2022ec8770 winbind: Add a GetNssInfo parent/child call
This call will be done in the idmap child. It is not 100% the right place,
but there is no better one available to me. It will become a replacement
for the "winbind nss info" parameter: This global parameter is good
for just one domain. It might be possible to have idmap backend AD for
different domains, and the NSS info like primary gid, homedir and shell
might be done with different policies per domain. As we already have a
domain-specific idmap configuration, doing the NSS info configuration
there also is the closest way to do it.

The alternative, if we did not want to put this call into the idmap child
would be to establish an equivalent engine like the whole "idmap config
*" just for the nss info. But as I believe this is closely related,
I'll just keep it in the idmap child.

This also extends the wbint_userinfo structure with pretty much all user
related fields. The idea is that the GetNssInfo call can do whatever it
wants with it.

f7f49a2354 idmap: Prime gencache after xids2sids calls
This fixes a performance regression for "hide unreadable". With an empty
gencache, we only do xid2sid calls when reading a large number of acls. We
lost caching the xid2sid calls while implmenting the multiple-id calls,
probably because at that time the bug with ID_TYPE_BOTH backends was still
pending. This patch restores the xid2sid caching hopefully correctly.

9c6c2ad26d idmap_autorid: Fix a race condition when acquiring ranges
Here we are in a transaction to create a range, but we already found
one to exist. We need to return the information about this range to the
caller, just as we do when actually allocating the range. This does not
hit us with current code, as we just have one idmap child. However, if
we parallelize that, two children might have found a domain to not exist
and call idmap_autorid_acquire_range simultaneously. One will create
the range, the other one will find it to already exist. The second child
will also have to pass the info up.

ba231d250a idmap_autorid: Fix checks for valid domains to allocate ranges for
The tdc cache is not reliable. The main dynamic check is
netsamlogon_cache_have: The only reliable way to see a domain as valid
for allocating a range for is a successful login. With a recent addition
to netsamlogon_cache_store, we can now reliably tell from there whether
a domain is trusted.

This also adds a few heuristic checks, such as allocation for the local
domains and additional ranges where we already have a mapping for range
index 0 for.

c21976d4b1 idmap: don't generally forbid id==0 from idmap_unix_id_is_in_range()
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.

9be918116e winbindd: in wb_lookupsids return domain name if we have it
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 "":

                             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.

2063692367 CVE-2016-2110: winbindd: add new_spnego to the WINBINDD_CCACHE_NTLMAUTH response
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".

d378c85f7a winbind: Fix a typo in a wrong comment...
While trying to disentangle this knot I could not stand to fix the obvious
typo. The whole comment is not really the whole story anymore, but that's a
commit for another day.

5d9069242d winbind: Add idmap_backend_unixids_to_sids
This is the plural version of idmap_backends_unixid_to_sid that expects all ids
to come from the same idmap domain. The singular version walks the domain list
itself, this one expects the domain name to be passed to it.
