Don't ask... Oh, you did? :-)
Try to figure out a hosts' name from lmhosts. This is for a setup I've
come across where for several reasons kerberos and ldap were unusable
(very organically grown but unchangeable Solaris 10 installation with
tons of ancient libs that ./configure incorrectly finds and where tar xf
samba-4.5.3.tar takes 5 minutes...), so I had to fall back to compile
with --without-ads. Unfortunately in that environment NetBIOS was also
turned off, but the "winbind rpc only" code relies on name_status to
get a DC's name from its IP address for the netlogon calls. This walks
the local lmhosts file to scan for the same information.

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.

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.

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.

This avoids the usage of the ccselect_realm logic in MIT krb5,
which leads to unpredictable results.
The problem is the usage of gss_acquire_cred(), that just creates
a credential handle without ccache.
As result gss_init_sec_context() will trigger a code path
where it use "ccselect" plugins. And the ccselect_realm
module just chooses a random ccache from a global list
where the realm of the provides target principal matches
the realm of the ccache user principal.
In the winbindd case we're using MEMORY:cliconnect to setup
the smb connection to the DC. For ldap connections we use
MEMORY:winbind_ccache.
The typical case is that we do the smb connection first.
If we try to create a new ldap connection, while the
credentials in MEMORY:cliconnect are expired,
we'll do the required kinit into MEMORY:winbind_ccache,
but the ccselect_realm module will select MEMORY:cliconnect
and tries to get a service ticket for the ldap server
using the already expired TGT from MEMORY:cliconnect.
The solution will be to use gss_krb5_import_cred() and explicitly
pass the desired ccache, which avoids the ccselect logic.
We could also use gss_acquire_cred_from(), but that's only available
in modern MIT krb5 versions, while gss_krb5_import_cred() is available
in heimdal and all supported MIT versions (>=1.9).
As far as I can see both call the same internal function in MIT
(at least for the ccache case).

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.
