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

hence whether we have to look up the policy in the database.

Add a hook, acl_redact_msg_for_filter(), in the aclread module, that
marks inaccessible any message elements used by an LDAP search filter
that the user has no right to access. Make the various ldb_match_*()
functions check whether message elements are accessible, and refuse to
match any that are not. Remaining message elements, not mentioned in the
search filter, are checked in aclread_callback(), and any inaccessible
elements are removed at this point.
Certain attributes, namely objectClass, distinguishedName, name, and
objectGUID, are always present, and hence the presence of said
attributes is always allowed to be checked in a search filter. This
corresponds with the behaviour of Windows.
Further, we unconditionally allow the attributes isDeleted and
isRecycled in a check for presence or equality. Windows is not known to
make this special exception, but it seems mostly harmless, and should
mitigate the performance impact on searches made by the show_deleted
module.
As a result of all these changes, our behaviour regarding confidential
attributes happens to match Windows more closely. For the test in
confidential_attr.py, we can now model our attribute handling with
DC_MODE_RETURN_ALL, which corresponds to the behaviour exhibited by
Windows.

that same request structure, as extended_dn_in would try to fix up the

having an extended DN, it would fall foul of the ldb_dn_match_allowed()

If we find that the backlink should not be visible on the given objectClass
by default, we now set DSDB_RMD_FLAG_HIDDEN_BL.
We'll evaluate that in the next commits in order to hide the
backlink by default.

Backlink attributes which are not "allowed" in objectClass 'top'
are always possible, but only visible by default based on the
real objectClass.
In order to avoid pay the cost for finding out if a backlink
should be visible or not, we remember a 'bool bl_maybe_invisible'
both on the forward link as well as the backlink dsdb_attribute.

msDS-KeyCredentialLink/msDS-KeyCredentialLink-BL are defined as linked attribute pair,
but msDS-KeyCredentialLink-BL is not defined as allowed on any object class definition,
still it's possible to create msDS-KeyCredentialLink attributes.
msDS-KeyPrincipal/msDS-KeyPrincipalBL are also defined as linked attribute pair
and msDS-KeyPrincipalBL is only allowed on object class 'user', but it's possible
to create msDS-KeyPrincipal values pointing to non 'user' objects.
The result is that 'user' objects have a visible msDS-KeyPrincipalBL, but
the others don't have msDS-KeyPrincipalBL visible, by default.
The backlinks are always visible if the backlink attributes are
explicitly requested.

All other tests use the same logic and run before, which means the ACE
is already there and is implicitly required.
As we want to cleanup the ACE after each test in the next step,
as the tests should not have side effects for other tests, e.g.
'blackbox.dbcheck'.

Instead of having one large function that returns every PAC blob, we now
have a more manageable assortment of smaller functions that each return
one blob.
That gives us more fine-grained handling of PAC blobs, with callers now
able to procure only the specific blobs that they need.

samba_kdc_get_pac_blobs() passes a pointer to a user_info_dc structure
obtained from samba_kdc_get_user_info_from_db() into
samba_add_asserted_identity(). The latter function modifies the SIDs of
the user_info_dc structure in order to add the Asserted Identity SID,
but samba_kdc_get_user_info_from_db() actually caches that structure
internally, meaning that subsequent calls will return the modified
structure.
We should not modify cached SIDs, so have
samba_kdc_get_user_info_from_db() return a pointer to constant data, and
copy the returned array of SIDs before adding the Asserted Identity SID.

It's getting unwieldy adding new PAC buffer types when each one has to
have its own handling. It also makes the possibility of mistakes more
likely.
Add a new container, 'struct pac_blobs', containing the types of PAC
buffers in a given PAC, with an index for quick access to the types we
support specifically. We can add new blobs (overriding existing ones) by
calling pac_blobs_add_blob(), and override certain blobs that must be
present with pac_blobs_replace_existing().
This removes the need to have a complicated 'switch' statement with
different logic for each PAC buffer type, or a dozen index variables.
