s4:kdc: tunnel the check_client_access status to hdb_samba4_audit()

Otherwise useful information gets lost while converting
from NTSTATUS to krb5_error and back to NTSTATUS again.
E.g. NT_STATUS_ACCOUNT_DISABLED would be audited as
NT_STATUS_ACCOUNT_LOCKED_OUT.

    s4:kdc: hdb_samba4_audit() is only called once per request

Normally these auth event types are overwritten with the
KDC_AUTH_EVENT_CLIENT_AUTHORIZED event type, but if a client passes the
pre-authentication check, and happens to fail the client access check
(e.g. because the account is disabled), we get error messages of the
form:
hdb_samba4_audit: Unhandled hdb_auth_status=9 => INTERNAL_ERROR

To avoid such errors, use the error code provided in the request
structure to obtain a relevant status code in cases not handled
explicitly.

For unexpected values we return KRB5KRB_ERR_GENERIC
in order to hopefully prevent success. And within make test
we panic in order let a ci run fail.

s4:auth: let authenticate_ldap_simple_bind() pass down the mapped nt4names

authenticate_ldap_simple_bind*() needs to pass the
result of the cracknames operation into the auth stack
as user_info->client.{account,domain}_name, because
user_info->client.{account,domain}_name is also used
when forwarding the request via netrLogonSamLogon*
to a remote server, for exactly that the values are
also used in order to map a AUTH_PASSWORD_PLAIN into
AUTH_PASSWORD_RESPONSE, where the NTLMv2 response
contains the account and domain names passed in the
netr_IdentityInfo value.

Otherwise it would not be possible to forward the
LDAP simple bind authentication request to a remote
DC.

Currently this only applies to an RODC that forwards
the request to an RWDC.

But note that LDAP simple binds (as on Windows) only
work for users in the DCs forest, as the DsCrackNames
need to work and it can't work for users of remote
forests. I tested that in a DC of a forest root domain,
if rejected the LDAP simple bind against a different forest,
but allowed it for a users of a child domain in the
same forest. The NTLMSSP bind worked in both cases.

s3:trusts_utils: use a password length of 120 for machine accounts

This is important when we change the machine password against
an RODC that proxies the request to an RWDC.

An RODC using NetrServerPasswordSet2() to proxy PasswordUpdateForward via
NetrLogonSendToSam() ignores a return of NT_STATUS_INVALID_PARAMETER
and reports NT_STATUS_OK as result of NetrServerPasswordSet2().
This hopefully found the last hole in our very robust machine account
password handling logic inside of trust_pw_change().

The lesson is: try to be as identical to how windows works as possible,
everything else may use is untested code paths on Windows.

A similar problem was fixed by this commit:

    commit 609ca657652862fd9c81fd11f818efb74f72ff55

        provision: Decrease the length of random machine passwords

        The current length of 128-255 UTF-16 characters currently causes
        generation of crypt() passwords to typically fail. This commit
        decreases the length to 120 UTF-16 characters, which is the same as
        that used by Windows.

    hdb: consolidate preauth audit event types

    Instead of having distinct preauth success/failure events for different

    the HDB_REQUEST_KV_PA_NAME key.

    in order to help the backend implement lockout.

    Audit failure (HDB_AUTH_EVENT_PREAUTH_FAILED) in the main preauth loop, rather
    than in each mechanism. Success is still audited in the mechanism to allow
    client pre-authentication success to be noted even if something subsequent
    (e.g. encoding a reply, memory allocation) fails. The generic catch-all for
