# Create Kerberos authentication files

In order to authenticate with Kerberos, you need to create the files with which Collibra DQ will access to authenticate your datasource connections.

## Prerequisites

You have:

* A krb5.conf file to store your Kerberos configuration information.
* Admin user permissions.

## Steps

{% tabs %}
{% tab title="Keytab" %}
{% stepper %}
{% step %}
Open a terminal session.
{% endstep %}

{% step %}
Run the following command with your own username:

```
kinit <your-username>
```

{% endstep %}

{% step %}
Enter the password of your keytab file.

{% hint style="info" %}
If any encryption-related messages appear, you can safely ignore them.
{% endhint %}
{% endstep %}

{% step %}
Run the following command with your file name:

```
kinit -c /tmp/<your-file-name>.keytab
```

You can define the location of your file, for example `/tmp/`.
