# Setting Up Kerberos in Vagrant Full Dev
**Note:** These are instructions for Kerberizing Metron Storm topologies from Kafka to Kafka. This does not cover the sensor connections or MAAS.
General Kerberization notes can be found in the metron-deployment [README.md](../README.md)

## Setup a KDC
See [Setup a KDC](Kerberos-manual-setup.md#setup-a-kdc) and [Verify KDC](Kerberos-manual-setup.md#verify-kdc)

## Ambari Setup
1. Kerberize the cluster via Ambari. More detailed documentation can be found [here](http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.3/bk_security/content/_enabling_kerberos_security_in_ambari.html).

    a. For this exercise, choose existing MIT KDC (this is what we setup and installed in the previous steps.)

    ![enable keberos get started](readme-images/enable-kerberos-started.png)

    b. Setup Kerberos configuration. Realm is EXAMPLE.COM. The admin principal will end up as admin/admin@EXAMPLE.COM when testing the KDC. Use the password you entered during the step for adding the admin principal.

    c. Click through to “Start and Test Services.” Let the cluster spin up.

## Push Data
1. Kinit with the metron user
    ```
    kinit -kt /etc/security/keytabs/metron.headless.keytab metron@EXAMPLE.COM
    ```

See [Push Data](Kerberos-manual-setup.md#push-data)
