f995c3805d CVE-2023-0614 tests/krb5: Add test for confidential attributes timing differences

d3fa2cb5dd CVE-2023-0614 s4:dsdb:tests: Fix <GUID={}> search in confidential attributes test
The object returned by schema_format_value() is a bytes object.
Therefore the search expression would resemble:

(lastKnownParent=<GUID=b'00000000-0000-0000-0000-000000000000'>)

which, due to the extra characters, would fail to match anything.

Fix it to be:

(lastKnownParent=<GUID=00000000-0000-0000-0000-000000000000>)

f154fad3c1 CVE-2023-0614 s4:dsdb/extended_dn_in: Don't modify a search tree we don't own
In extended_dn_fix_filter() we had:

    req->op.search.tree = ldb_parse_tree_copy_shallow(req, req->op.search.tree);

which overwrote the parse tree on an existing ldb request with a fixed
up tree. This became a problem if a module performed another search with
that same request structure, as extended_dn_in would try to fix up the
already-modified tree for a second time. The fixed-up tree element now
having an extended DN, it would fall foul of the ldb_dn_match_allowed()
check in extended_dn_filter_callback(), and be replaced with an
ALWAYS_FALSE match rule. In practice this meant that <GUID={}> searches
would only work for one search in an ldb request, and fail for
subsequent ones.

Fix this by creating a new request with the modified tree, and leaving
the original request unmodified.

Backlink attributes which are not "allowed" in objectClass 'top'

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'

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.

bfc33b47bb dsdb: Avoid ERROR(ldb): uncaught exception - Deleted target CN=NTDS Settings... in join
"samba-tool domain join" uses the replication API in a strange way, perhaps no longer
required, except that we often still have folks upgrading from very old Samba versions.

When deferring the writing out to the DB of link replication to the very end, there
is a greater opportunity for the deletion of an object to have been sent with the
other objects, and have the link applied later.

This tells the repl_meta_data code to behave as if GET_TGT had been sent at the
time the link was returned, allowing a link to a deleted object to be silently
discarded.
