This avoids any DNs being a free pass beyond the ACL code, instead it is based on the CN=Partitions ACL.

We should only use dsdb_module_check_access_on_dn() on the parent.

This will, when the GUID is entered into the object tree (not in this
commit) ensure that access rights assigned to the structural
objectClass are also available, as well as rights assigned to the
attribute property groups.

This uses dsdb_get_last_structural_objectclass(), which encodes this ordering
knowledge in one place in the code, rather than using this uncommented
magic expression:
(char *)oc_el->values[oc_el->num_values-1].data

acl_check_access_on_attribute should never be called with attr=NULL
because we don't check access on an attribute in that case

First we check for a special dn, then for system access.
All allocations happen after this checks in order to avoid
allocations we won't use.

This fix frequent reindexing when using python script with a
user that is not system.
The reindexing is caused by ACL module hidding (removing) attributes in
the search request for all attributes in dn=@ATTRIBUTES and because
dsdb_schema_set_indices_and_attributes checks that the list of
attributes that it just calculated from the schema is the same as the
list written in @ATTRIBUTES, if not the list is replaced and a
reindexing is triggered.

This seems inefficient, but is needed for correctness. The
alternative might be to have the sec_access_check_ds code confirm that
*all* of the nodes in the object tree have been cleared to
node->remaining_bits == 0.
Otherwise, I fear that write access to one attribute will become write
access to all attributes.

(cherry picked from commit d776fd807e0c9a62f428ce666ff812655f98bc47)
The searches are done in order to do access checks
and the results are not directly exposed to the client.
Note that SHOW_RECYCLED implies SHOW_DELETED.

This patch addresses a segfault in acl_validate_spn_value which occurs
when the "dnsHostName" attribute is missing. This seems to be the case
in domains migrated with samba3upgrade. Looks similar to MS KB 817543.

We need to ensure that if this parses name.name_string as just one
val, then we don't read uninitialised and possibly unallocated memory.

While we are checking that, we need to fix the strncasecmp() check to
first check if the string is the expected length, then check for a
match against sAMAccountName-without-doller, as otherwise we will
permit a string such as machinefoo to match a sAMAccountName of
machine.
