c69174c07c s4:kdc: pass krbtgt skdc_entries to samba_kdc_update_pac()
For now we only pass in the krbtgt that verified the client pac
and optionally the krbtgt that verified the device pac.

These can be different depending on the domain of the related
principals.

If we want to apply SID filtering in future we may also need
to pass in the krbtgt that verified the delegated_proxy_pac,
but that needs more research and if not required for the
following changes.

3240ac4ebe s4:kdc: Check authentication policy server restrictions
For a constrained delegation request, we need to pass ‘delegated_proxy’
(and the delegated proxy PAC, if one was provided) into
samba_kdc_update_pac() so that we can verify that the delegating server
is allowed to authenticate to the target server.

The ‘const’ is entirely unnecessary in a function declaration, but we
add it just to be consistent.

456373ac19 tests/krb5: Don’t unnecessarily specify ‘id’
In tests where we have multiple accounts of the same type, we use the
‘id’ parameter to ensure that these accounts are all different, as some
restrictions are bypassed if an account authenticates to the selfsame
account. However, this is unnecessary if we already specify (with
‘use_cache=False’) that the cache is not to be used.

19f867bc54 s4:kdc: Ensure that we don’t log PREAUTH_REQUIRED errors
Such errors were not logged in the past, either, but that was accidental
— a result of failing too early for an authentication event to be set —
rather than the auditing being deliberately designed that way.

Now that we have added the KDC_AUTH_EVENT_CLIENT_FOUND event, we want to
ensure that PREAUTH_REQUIRED errors continue to go unlogged.
