Logstash plugged on a kerberized kafka

Hi everybody

I want to define a kerberized kafka as an output for logstash.
I tested my securized kafka that seams to work fine, but how to pass transparently a ticket with logstash in such a case. I do not find any option with a keytab reference...

Did someone already do it ?
We want to suscribe for the shield feature, but it does not worth if all our data can be get from our broker...
