Andrew Bartlett cfeb9fe50e CVE-2023-4154: Unimplement the original DirSync behaviour without LDAP_DIRSYNC_OBJECT_SECURITY
This makes LDAP_DIRSYNC_OBJECT_SECURITY the only behaviour provided by
Samba.

Having a second access control system withing the LDAP stack is unsafe
and this layer is incomplete.

The current system gives all accounts that have been given the
GUID_DRS_GET_CHANGES extended right SYSTEM access.  Currently in Samba
this equates to full access to passwords as well as "RODC Filtered
attributes" (often used with confidential attributes).

Rather than attempting to correctly filter for secrets (passwords) and
these filtered attributes, as well as preventing search expressions for
both, we leave this complexity to the acl_read module which has this
facility already well tested.

The implication is that callers will only see and filter by attribute
in DirSync that they could without DirSync.
