You are joined but the server isn't registered in DNS because the server
is not sending its fqdn. So:
net ads leave -UAdministrator
add the fqdn to the localhost line in /etc/hosts something like: localhost server.family.local server
add the line:
kerberos method = system keytab
to the [global] section of smb.conf
net ads join -UAdministrator

Use this as /etc/krb5.conf:
        default_realm = FAMILY.LOCAL
        dns_lookup_realm = false
        dns_lookup_kdc = true

Worry about ticket lifetimes and other stuff later.
