# Ensure LDAP client is not installed
 
## Description{% #description %}

The Lightweight Directory Access Protocol (LDAP) is a service that provides a method for looking up information from a central database. The `ldap-utils` package can be removed with the following command:

```

$ apt-get remove ldap-utils
```

## Rationale{% #rationale %}

If the system does not need to act as an LDAP client, it is recommended that the software is removed to reduce the potential attack surface.

## Remediation{% #remediation %}

### Shell script{% #shell-script %}

The following script can be run on the host to remediate the issue.

```bash
#!/bin/bash

# CAUTION: This remediation script will remove ldap-utils
# from the system, and may remove any packages
# that depend on ldap-utils. Execute this
# remediation AFTER testing on a non-production
# system!


DEBIAN_FRONTEND=noninteractive apt-get remove -y "ldap-utils"
```

### Ansible playbook{% #ansible-playbook %}

The following playbook can be run with Ansible to remediate the issue.

```
