5c1e2f564b winbindd: avoid refreshing sequence number when domain is offline
When there's no connectivity to the domain, avoid attempt to
refresh sequence number. Before the change, this was avoided
only if winbind offline logon was enabled. However, being
able to operate based on cached data is desired even when
offline logons are disabled (offline logons are about caching
credentials for PAM authentication, a user may not want this
and still want service from the SMB server during short
AD disconnects).

c819c7d58f winbindd: queryuser - only get group name if needed
When calculating the user entry for a user, the
primary group id *name* might be needed if it is
part of a home dir / shell template (%g or %G).

Only resolve primary group SID to primary group name
if it is needed, thereby saving a round-trip to the DC
(and better handling situations where it is disconnected).

e3a151e247 winbindd: cache name-to-sid from PAC based on lookup domain
The name-to-sid lookup for trusted domains is not necessarily
done against the domain - in AD member case it is done
against the primary domain. Therefore the caching should also
be done against the lookup domain.

fe7020b0d1 idmap_ad: Retry query_user exactly once if we get TLDAP_SERVER_DOWN
All other ldap-querying methods in idmap_ad make a single retry attempt if they get
TLDAP_SERVER_DOWN. This patch brings idmap_ad_query_user in line with that design.

This fixes the symptom described in 12720 at the cost of an additional reconnect per
failed lookup.

This allows you to forward bad password count resets to 0. Currently,
there is a missing access check for the RODC to ensure it only applies
to cached users (msDS-Allowed-Password-Replication-Group).

(further patches still need to address forcing a RWDC contact)

            result                   : NT_STATUS_OK

So the name for S-1-5-21-3293503978-489118715-2763867031-1106 has
S-1-5-21-1387724271-3540671778-1971508351 in referenced lsa_DomainInfo
structure. In that case we should not use the domain name from lsa_DomainInfo,
because we would use the wrong idmap backend.

For the case where the domain part of the sIDHistory sid is a still existing
domain, which can be found our internal list of trusted domains, we now use the
correct idmap backend: the idmap domain from the historic SID.

If the historic domain does no longer exist, we will fallback to the default
idmap domain.

The next step would be doing a lookup sid call for the domain sid, which may
help with one-way trusts.

The long term goal needs to be that idmap backends are based on sids only and
only the smb.conf allows names to be used which will be converted to sids on
startup.

c91bac5a63 winbind: Simplify a logic expression
This isn't 100% the same flow, but before this patch we initialized
domain->primary to "false" via "talloc_zero". This means that the
end-result should be the same before and after this patch that IMHO
simplifies the logic a bit.

8220d7453f winbindd: remove fallback from lookuprids
We're only calling lookuprids for our local SAM and BUILTIN domains, if
that results in a failed lookup for some rid, sending it again via
lookupsids() won't help, it will just fail again.

If the caller wrongly had sent any other SID that is not from our SAM or
BUILTIN via lookuprids(), that it is up to the caller to fix that, not
us.

The retry logic with going through the single sids lookup at the end
added a fake domain with an empty string. The wb_lookupsids caller
wb_sids2xids needed this, as it wasn't doing the needed error handling
itself. As wb_sids2xids has been fixed to cope, we can just fail the
lookupsids here.

It's up to callers like wb_sids2xids to handle such failed mappings and

1efaeb072e winbindd: handling of SIDs without domain reference in wb_sids2xids_lookupsids_done()
This lets wb_sids2xids_lookupsids_done() deal with wp_lookupsids
returning UINT32_MAX as domain index for SIDs from unknown domains.

Call find_domain_from_sid_noinit() to search our list of known
domains. If a matching domain is found, use it's name, otherwise use the
empty string "". This needed to handle Samba DCs which always returns
sid_index UINT32_MAX for unknown SIDs, even from known domains.

Currently the wb_lookupsids adds these fake domains with an empty string
as domain name, but that's not the correct place to do it. We need the
domain name as it gets passed to the idmap child where the choise of
idmap backend is based on the domain name. This will possibly be changed
in the future to be based on domain SIDs, not the name.

a684df160e winbindd: use correct domain name for failed lookupsids
What we want here is, for failed lookupsids, pass the domain name of the
SID we were trying to lookup to the idmap backend.

But as a domain member, using

  state->single_domains[state->single_sids_done]

for this purpose will always be use our primary domain name (for S-1-5-21
SIDs that are not in our local SAM).

So for now use find_domain_from_sid_noinit() to find the domain from the
domain list. This can be removed when we switch idmap backend
determination to be based on domain SIDs, not names.

of libwbclient, we should avoid having the complexity to do additional
network roundtrips to our domain, while we still can't garantee that
the returned password policy actually represents the reality for
the current authentication.

Instead we're calculating r->data.auth.policy.expire and
r->data.auth.policy.min_passwordage based on the effective
{last,allow,force}_password_change values.
