The Lightweight Directory Access Protocol (LDAP) was introduced as a replacement for NIS/YP. It is a service that provides a method for looking up information from a central database.
If the system will not need to act as an LDAP client, it is recommended that the software be removed to reduce the potential attack surface.
Removing the LDAP client will prevent or inhibit using LDAP for authentication in your environment.
Verify that ldap-utils is not installed. Use the following command to provide the needed information:
# dpkg-query -s ldap-utils &>/dev/null && echo "ldap-utils is installed"
Nothing should be returned.
Uninstall ldap-utils:
# apt purge ldap-utils
