2.3.5 Ensure LDAP client is not installed

Information

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.

Rationale:

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.

Impact:

Removing the LDAP client will prevent or inhibit using LDAP for authentication in your environment.

Solution

Uninstall ldap-utils using the appropriate package manager or manual installation:

# apt-get remove ldap-utils
