### Setting up password-less kerberos token

In order for the kerberos token to be refreshed automatically, it must be possible to do so without a password.
Therefore, we create a keytab (similar to a private ssh key) on lxplus using the keytab utility.
Therefore, we create a keytab (similar to a private ssh key) on lxplus using the provided `cern-get-keytab` utility. Note it will prompt for your password, in order to generate the keytab.

{% callout "The old way" %}

The former recipe was to start `ktutil`, then type the following three lines into the prompt and confirm the first two steps with your password.
```bash
add_entry -password -p [email protected] -k 1 -e arcfour-hmac-md5
add_entry -password -p [email protected] -k 1 -e aes256-cts
wkt USERNAME.keytab
cern-get-keytab --user USERNAME --keytab USERNAME.keytab
```
and close the `ktutil` prompt with `Ctrl+D`.
This would create a file called USERNAME.keytab in the current directory.
