Dear Maintainer,

I'm setting up an AD authenticated machine. I have problem with credentials cache. KRB5 insists the cache file to be /tmp/krb5cc_{%euid}
Thus, the file is deleted after reboot. However, I want to enable cached (offline) login, so I set in /etc/krb5.conf in [libdefaults] section:
default_ccache_name = /var/cache/krb5/krb5cc_{%euid}

The KRB5 seems to ignore the setting, klist shows cache file still to be in the default location
