idmap_hash used to bounce back the requested type,
which was ID_TYPE_UID, ID_TYPE_GID or ID_TYPE_NOT_SPECIFIED
before as the winbindd parent always used a lookupsids.
When the lookupsids failed because of an unknown domain,
the idmap child weren't requested at all and the caller
sees ID_TYPE_NOT_SPECIFIED.
This module should have supported ID_TYPE_BOTH since
samba-4.1.0, similar to idmap_rid and idmap_autorid.
Now that the winbindd parent will pass ID_TYPE_BOTH in order to
indicate that the domain exists, it's better to always return
ID_TYPE_BOTH instead of a random mix of ID_TYPE_UID, ID_TYPE_GID
or ID_TYPE_BOTH. In order to request a type_hint it will return
ID_REQUIRE_TYPE for ID_TYPE_NOT_SPECIFIED, which means that
the parent at least assures that the domain sid exists.
And the caller still gets ID_TYPE_NOT_SPECIFIED if the
domain doesn't exist.

Some very old NT4 DCs might have not returned the account flags filled in. This
shouldn't be a problem anymore. Additionally, on a typical domain member server,
this request is (and can only be) send to the primary domain, so this will not
work with accounts from trusted domains.

Under the following conditions a user from an ignored domain might be able to
authenticate:
- using Kerberos
- successfully previous authentication so the idmap and name caches are filled
- winbind not running (fwiw, winbindd is mandatory on a domain member)
- nscd running with a cached getpwnam for the ignored user (otherwise auth fails
because getpwnam fails)
- lookup_name() function being modified to look into the name cache before
contacting winbindd. Currently it talks directly to winbindd and that will
check the cache.
Currently, authentication will only fail because creating the local token for
the user fails because an LSA lookupname RPC call fails (because winbindd is not
running).
All of this makes a successfull authentication unlikelly, but that is more by
accident then by design.
To ensures that if winbindd is not running and as such winbindd itself can not
enforce the restriction, also implement the ignored domains check in the auth
system as a last line of defense.

For some reason the join fails to register the DNS records when provisioning the
member env:
Using short domain name -- SAMBA2008R2
Joined 'IDMAPADMEMBER' to dns domain 'samba2008r2.example.com'
DNS Update for idmapadmember.samba.example.com failed: ERROR_DNS_UPDATE_FAILED
At the same time the hosts file used by the wrappers contains the wrong fqdn. As
a result the test that the next commit is going do add fails due do the broken
DNS resolution:
...
UNEXPECTED(failure): samba3.blackbox.winbind_ignore_domain.test_winbind_ignore_domains_ok_krb5(ad_member_idmap_ad:local)
REASON: Exception: Exception: do_connect: Connection to idmapadmember.samba2008r2.example.com failed (Error NT_STATUS_UNSUCCESSFUL)
...
Checking DNS in the testenv, first the working record for the main DC:
testenv$ dig @10.53.57.64 dc7.samba2008r2.example.com +short
10.53.57.27
testenv$ bin/samba-tool dns query dc7 samba2008r2.example.com dc7 A -U Administrator%locDCpass7
Name=, Records=1, Children=0
A: 10.53.57.27 (flags=f0, serial=1, ttl=900)
Now the failing idmapadmember:
testenv$ dig @10.53.57.64 idmapadmember.samba2008r2.example.com +short
testenv$ bin/samba-tool dns query dc7 samba2008r2.example.com idmapadmember A -U Administrator%locDCpass7
ERROR: Record or zone does not exist.
Fixing the hosts file lets the tests work, fixing the broken DNS record
registration is a task for another day.
