A user that doesn't have access to view an attribute can still guess the
attribute's value via repeated LDAP searches. This affects confidential
attributes, as well as ACLs applied to an object/attribute to deny
access.
Currently the code will hide objects if the attribute filter contains an
attribute they are not authorized to see. However, the code still
returns objects as results if confidential attribute is in the search
expression itself, but not in the attribute filter.
To fix this problem we have to check the access rights on the attributes
in the search-tree, as well as the attributes returned in the message.
Points of note:
- I've preserved the existing dirsync logic (the dirsync module code
suppresses the result as long as the replPropertyMetaData attribute is
removed). However, there doesn't appear to be any test that highlights
that this functionality is required for dirsync.
- To avoid this fix breaking the acl.py tests, we need to still permit
searches like 'objectClass=*', even though we don't have Read Property
access rights for the objectClass attribute. The logic that Windows
uses does not appear to be clearly documented, so I've made a best
guess that seems to mirror Windows behaviour.

Currently Samba is a bit disclosive with LDB_OP_PRESENT (i.e.
attribute=*) searches compared to Windows.
All the acl.py tests are based on objectClass=* searches, where Windows
will happily tell a user about objects they have List Contents rights,
but not Read Property rights for. However, if you change the attribute
being searched for, suddenly the objects are no longer visible on
Windows (whereas they are on Samba).
This is a problem, because Samba can tell you about which objects have
confidential attributes, which in itself could be disclosive.
This patch adds a acl.py test-case that highlights this behaviour. The
test passes against Windows but fails against Samba.

Adds tests that assert that a confidential attribute cannot be guessed
by an unprivileged user through wildcard DB searches.
The tests basically consist of a set of DB searches/assertions that
get run for:
- basic searches against a confidential attribute
- confidential attributes that get overridden by giving access to the
user via an ACE (run against a variety of ACEs)
- protecting a non-confidential attribute via an ACL that denies read-
access (run against a variety of ACEs)
- querying confidential attributes via the dirsync controls
These tests all pass when run against a Windows Dc and all fail against
a Samba DC.

One of the use-cases for the domain rename tool is to produce a lab
domain that can be used for pre-production testing of Samba.
Basically this involves taking a backup rename with --no-secrets (which
scrubs any sensitive info), and then restoring it.
This patch adds a testenv that mimics how a user would go about creating
a lab-domain. We run the same tests that we run against the restore and
rename testenvs.
Note that the rpc.echo tests for the testallowed and testdenied users
fail, because we don't backup the secrets for these users. So these
tests failing proves that the lab-DC testenv is correct.

This adds a new testenv for testing that a DC created using the
samba-tool backup/restore can actually be started up. This actually
requires 2 new testenvs:
1. A 'backupfromdc' that solely exists to make a online backup of.
2. A 'restoredc' which takes the backup, and then uses the backup file
to do a restore, which we then start the DC based on.
The backupfromdc is just a plain vanilla AD DC. We use a separate test
env purely for this purpose, because the restoredc will use the same
domain (and so using an existing testenv would potentially interfere
with existing test cases).
