Kerberos certainly is possible and here's a good high level article discussing it:
You could go the enterprise security route EUS, which may be more suitable for what you might be looking for re "end to end".
EUS is part of the Advanced Security option of the database and as of now requires extra licensing where as kerberos does not.
Thanks for your reply.
Our upcoming solution will be on an enterprise platform with Kubernetes support. One key area we are trying to bridge is maintaining our Kerberos authentication to the Oracle DB via our app on the Kubernetes containers deployment platform. We are not sure if our apps hosted within the containers are able to acquire user Kerberos ticket and pass it all the way down to our Oracle database tier.
There are other alternatives to connect to Oracle DB, however we are trying to exhaust all options with Kerberos before moving on reluctantly.
Appreciate any advice on whether there are any such implementations out there (similar to our scenario) to the Oracle DB.
