2ad4468622 s4:auth_sam: use USER_INFO_INTERACTIVE_LOGON as inducation for an interactive logon
Using != AUTH_PASSWORD_RESPONSE is not the correct indication
due to the local mappings from AUTH_PASSWORD_PLAIN via
AUTH_PASSWORD_HASH to AUTH_PASSWORD_RESPONSE.

It means an LDAP simble bind will now honour
'old password allowed period'.

94d387abd5 s4:kdc: Adapt to hdb_entry_ex removal
Rather than having a 'free_entry' member that can be called to free an
hdb_entry, we now implement the free function in HDB. We perform the
free only if the context pointer is non-NULL.

We also remove the ZERO_STRUCTP() in sdb_entry_to_hdb_entry(), as the
context pointer is now part of the 'hdb_entry' structure itself, and
this would undesirably zero it out.

    hdb: consolidate preauth audit event types

    Instead of having distinct preauth success/failure events for different
    mechanisms, have a single event; the mechanism can be disambiguated by querying
    the HDB_REQUEST_KV_PA_NAME key.

    Note: there is still an explicit event for long-term key-based success/failure
    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
    success remains.

7989ef0aa7 s4:kdc: Adapt to removal of auth event details
This is an adaptation to Heimdal:

commit e15e711b13e2fb33f4480a054cba60b6c4c0183b
Author: Luke Howard <lukeh@padl.com>
Date:   Sat Jan 1 18:05:51 2022 +1100

    kdc: remove auth_event_details audit key

    The auth event details audit key (formerly, parameter to auth_status)
    contained, variously, an encryption type name; a PKINIT client certificate
    name; or, a GSS initiator name. Audit these instead using individual keys that
    reflect the values' contents.

    kdc: refactor Samba-specific auditing API in terms of existing API

    Make Samba-specific HDB auth status API a wrapper on the existing auditing API,
    with a view towards unifying the two APIs in a future commit.

    The term "auth status" is replaced with "auth event", and the HDB auth_status
    method is replaced with a more general purpose audit method which has access to
    the entire request structure.

9936038fae s4:kdc: Don't pass empty PAC buffers to krb5_pac_add_buffer()
Heimdal will no longer allow us to pass a dummy zero-length buffer to
krb5_pac_add_buffer(), so we have to pass a buffer of length 1 instead.

This is an adaption to Heimdal:

commit 190263bb7a56fc775b50a6cd0dc91820d2b2e5eb
Author: Jeffrey Altman <jaltman@secure-endpoints.com>

    assert non-NULL ptrs before calling mem funcs

    The definitions of memcpy(), memmove(), and memset() state that
    the behaviour is undefined if any of the pointer arguments are
    NULL, and some compilers are known to make use of this to
    optimise away existing NULL checks in the source.
