The logic for constructing the values for our own primary domain differs
from the values of trusted domains. In order to make the code easier to
understand we have a new fill_our_one_domain_info() helper that
only takes care of our primary domain.
The cleanup for the trust case will follow in a separate commit.

This is not a general purpose profiling solution, but these JSON logs are already being
generated and stored, so this is worth adding.
Some administrators are very keen to know how long authentication
takes, particularly due to long replication transactions in other
processes.
This complements a similar patch set to log the transaction duration.

So far, I have never observed the case where the winbind call ever
bothered to return a proper site, but in case it ever does so, we
clobber it here. This has implications for returning a non-local domain
site name, but for now, we ignore them.

Here we simply forward everything without alteration (the same struct is
returned). This helps us to fix the case where the DC does not exist in
the target site, furthermore, this is supposed to work for trusted
domains.
In calling out to winbind, we now also notice if you provide a site
which exists in multiple domains and provide the correct domain (instead
of accidentally returning ourselves).

This patch fixes an issue where NetApp filers joined to a
Samba/ADDC cannot resolve SIDs. Without this patch the issue
can only be avoided by setting "allow nt4 crypto = yes" in smb.conf.
The issue is triggered by NetApp filers in three steps:
1. The client calls netr_ServerReqChallenge to set up challenge tokens
2. Next it calls netr_ServerAuthenticate2 with NETLOGON_NEG_STRONG_KEYS
set to 0. Native AD and Samba respond to this with
NT_STATUS_DOWNGRADE_DETECTED. At this point Samba throws away
the challenge token negotiated in the first step.
3. Next the client calls netr_ServerAuthenticate2 again, this time with
NETLOGON_NEG_STRONG_KEYS set to 1.
Samba returns NT_STATUS_ACCESS_DENIED as it has lost track
of the challenge and denies logon with the message
No challenge requested by client [CLNT1/CLNT1$], cannot authenticate
Git commit 321ebc99b5 introduced
a workaround for a different but related issue. This patch makes a minor
adjustment to that commit to delay flushing the cached challenge until
it's clear that we are not in a NT_STATUS_DOWNGRADE_DETECTED
situation.

Some clients call netr_ServerReqChallenge() and netr_ServerAuthenticate3()
on different connections. This works against Windows DCs as they
have a global challenge table.
A VMware provisioning task for Windows VMs seemy to rely on this behavior.
As a fallback we're storing the challenge in a global memcache with a fixed
size. This should allow these strange clients to work against a
Samba AD DC.

This changes auth_serversupplied_info into the IDL-defined struct
auth_user_info_dc. This then in turn contains a struct
auth_user_info, which is the only part of the structure that is
mainted into the struct session_info.
The idea here is to avoid keeping the incomplete results of the
authentication (such as session keys, lists of SID memberships etc) in
a namespace where it may be confused for the finalised results.
