Samba security features like AD claims, Authentication Policies and
Authentication Silos are enabled once the DC is at the required functional level.
We comment at the callers of of dsdb_dc_functional_level() to explain
why we do this.

All that uses the FAST cookie is the gss-preauth authentication
mechanism, which is untested in Samba, and disabled by default.
Disabling the FAST cookie code (and sending a dummy string instead)
relieves us of the maintenance and testing burden of this untested code.

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

hdb_samba4_get_ntstatus() gets that status code back from the request

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.
