InformationThe 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.
SolutionUninstall ldap-utils using the appropriate package manager or manual installation:
# apt-get remove ldap-utils
Removing the LDAP client will prevent or inhibit using LDAP for authentication in your environment.
