Ecto + Kerberos Authentication to Oracle Database?

I’m building out a POC at work in an attempt to showcase the Elixir/Erlang ecosystem could be a good fit for our applications and services. The only viable option I have to use for a DBaaS on our private cloud is Oracle (been looking at jamdb_oracle as an Ecto adapter) and to use that we have to authenticate with Kerberos. I’ve poured over the documentation and I haven’t seen anything that indicates Kerberos-based authentication is supported. We’re mostly a JVM shop for the backend, so getting that configured for our JVM applications is well documented.
