Your TGT will eventually expire, but that hardly matters since you're<br>
offline. When you reconnect to the network, you can either run kinit<br>
manually, or for better user experience enable krb5_store_password_if_offline<br>
to keep your password in the kernel keyring and let sssd kinit on your<br>
behalf when it detects you've gone online again.<br>
