Trust accounts can only use kerberos when contacting other AD domains,
using NTLMSSP will fail.
At the same time it doesn't make sense to try kerberos for NT4 domains,
still NTLMSSP will fail, but the callers has to deal with that
case and just fallback to an anonymous SMB connection.
In all cases we should be able to use NETLOGON SCHANNEL
over any anonymous smb or tcp transport.

We're using only NCACN_NP here as we rely on the smb signing restrictions
of cm_prepare_connection().
This should fix SMB authentication with a user of a domain
behind a transitive trust.
With this change winbindd is able to call
dcerpc_netr_DsrEnumerateDomainTrusts against the
dc of a trusted domain again. This only works
for two-way trusts.
The main problem is the usage of is_trusted_domain()
which doesn't know about the domain, if winbindd can't
enumerate the domains in the other forest.
is_trusted_domain() is used in make_user_info_map(),
which is called in auth3_check_password() before
auth_check_ntlm_password().
That means we're mapping the user of such a domain
to our own local sam, before calling our auth modules.
A much better fix, which removes the usage of is_trusted_domain()
in planed for master, but this should do the job for current releases.
We should avoid talking to DCs of other domains and always
go via our primary domain. As we should code with one-way trusts
also, we need to avoid relying on a complete list of
domains in future.
For now "wbinfo -m" lists domains behind a two-way transitive
trust again, but that is likely to change in future again!

This reverts commit d2379caa77.
This change doesn't solve the real problem, it just
causes useless network traffic and the following error:
rpccli_setup_netlogon_creds failed for W2012R2-L6, unable to setup NETLOGON
credentials: NT_STATUS_NO_TRUST_SAM_ACCOUNT
While the old logic caused NT_STATUS_CANT_ACCESS_DOMAIN_INFO (without
network traffic) instead of the NT_STATUS_NO_TRUST_SAM_ACCOUNT.
A better fix will follow.

"ctdb reloadips" use of ipreallocate() can result in a spurious
takeover runs. This can cause a subsequent "ctdb reloadips" to fail
to disable takeover runs (due to there being one already in progress).
There are various possible improvements but a proper fix probably
requires a protocol change. That would mean receiving an ACK for a
takeover run request to indicate that the request will be processes
and then a broadcast to indicate a completed takeover run.
There are various other partial fixes (e.g. de-duping queued takeover
run requests against those in the in-progess queue) and workarounds
(e.g. always do a double ipreallocate() in the tool, which should
absorb the spurious takeover run).
However, this is unlikely to be a real-world problem. Real use cases
should not involve repeatedly reloading the IP configuration.
Instead, work around the problem of flaky tests by manually adding
"ctdb sync" commands to cause extra no-op takeover runs. These should
not add spurious takeover runs and will create synchronisation points
to help avoid the issue.
