# Uninstall the nis package
 
## Description{% #description %}

The support for Yellowpages should not be installed unless it is required.

## Rationale{% #rationale %}

NIS is the historical SUN service for central account management, more and more replaced by LDAP. NIS does not support efficiently security constraints, ACL, etc. and should not be used.

## 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 nis
# from the system, and may remove any packages
# that depend on nis. Execute this
# remediation AFTER testing on a non-production
# system!


DEBIAN_FRONTEND=noninteractive apt-get remove -y "nis"
```

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