Uninstall openldap-servers Package

An XCCDF Rule

Description

The slapd package is not installed by default on a Ubuntu 16.04 system. It is needed only by the OpenLDAP server, not by the clients which use LDAP for authentication. If the system is not intended for use as an LDAP Server it should be removed.

Rationale

Unnecessary packages should not be installed to decrease the attack surface of the system. While this software is clearly essential on an LDAP server, it is not necessary on typical desktop or workstation systems.
