Long time logins
Once you initialize a session, the authentication credentials are automatically requested. There is a configuration in place to renew these credentials. The limitation is that this is only possible for 7 days without providing your credentials again. So if you want to achieve a session keeps itself alive for longer than 7 days you need to create a keytab File, which saves your credentials encrypted and can be used to authenticate automatically.
How to create your personal keytab file:
Run this script: /usr/local/bin/CreateKeytab.sh
