strptime() will fail to parse the LDAP ‘whenCreated’ time string,
because the format string is wrong: it will expect to get a time like
“20230920043849Z”, but the time string seems to be actually formatted

Having pac_blobs::type_blobs be managed both by talloc and by the
‘pac_blobs’ structure itself (with pac_blobs_destroy()) is very prone to
error. So is the current situation of having the other ‘pac_blobs’
functions each take in a memory context.
Improve these circumstances by requiring ‘pac_blobs’ to be managed by
talloc. Now the other functions can dispense with their ‘mem_ctx’
parameters, being instead able to allocate on to the ‘pac_blobs’
structure itself. pac_blobs_init() no longer must be a separate
function; inline it into pac_blobs_from_krb5_pac(). pac_blobs_destroy(),
being no longer of use, can go too.

I’m not sure exactly how this check was supposed to work. But in any
case, within fast_unwrap_request() the Heimdal KDC replaces the outer
padata with the padata from the inner FAST request. Hence, this check
does not accomplish anything useful: at no point should the KDC plugin
see the outer padata.
A couple of unwanted consequences resulted from this check. One was that
a client who sent empty FX‐FAST padata within the inner FAST request
would receive the *Authentication Authority* Asserted Identity SID
instead of the *Service* Asserted Identity SID. Another consequence was
that a client could in the same manner bypass the restriction on
performing S4U2Self with an RODC‐issued TGT.
Overall, samba_wdc_is_s4u2self_req() is somewhat of a hack. But the
Heimdal plugin API gives us nothing better to work with.

This is more consistent with the non-NULL parameters, and makes it
easier to swap in the real values when we get them.

KRB5_PADATA_PW_SALT is wrong. It’s an unrelated constant that just
happens to share the same value.
Heimdal uses the correct constant, kERB_ERR_TYPE_EXTENDED.

The ticket returned by kdc_request_get_ticket() is the main TGT
presented in a TGS-REQ. If we’re verifying a FAST armor ticket or a
user-to-user ticket, make sure we check the lifetime of that ticket
instead. To do this we need to pass the appropriate ticket into the
plugin function.

If an NTSTATUS code has been set in the KDC request structure, encode it
as KERB-ERROR-DATA and add it to the KDC reply.
hdb_samba4_set_ntstatus() adds the NTSTATUS code to the request
structure.
hdb_samba4_get_ntstatus() gets that status code back from the request
structure.
hdb_samba4_set_edata_from_ntstatus() encodes the status code and adds it
to the reply.

This corresponds with the HDB_F_ARMOR_PRINCIPAL flag in Heimdal, and
indicates a lookup of an armor ticket client principal, rather than the
principal of the main TGT. This helps us to determine whether an
authentication policy will apply to a principal acting as a client, and
hence whether we have to look up the policy in the database.

These functions are not yet used.
They are arranged into two libraries: ‘authn_policy’, containing the
core functions, and ‘authn_policy_util’, containing utility functions
that can access the database. This separation is so that libraries
depended upon by ‘samdb’ or ‘dsdb-module’ can use the core functions
without introducing a dependency cycle.

Just copying the structure fields is prone to lead to use-after-frees if
we access them after the original structure and its fields are freed.
Instead, call authsam_shallow_copy_user_info_dc() to make the copy. This
properly references the fields in the original structure so that they
will not be freed until we are sure we have finished with them.
