Reuse token that was recovered from strimzi oauth

[jonatasvieira]

I was looking if is it possible to use the token recovered from kafka. We have an architecture here that each microservice has its own cliendId and secret and we need this token to do other actions on other systems. To avoid new call to our oracle access manager, I was wondering if is possible to recover the token to use it.

@mstruk any suggestions?

The event to call into Strimzi OAuth and provide the access token on the client is triggered by kafka-clients code, the token is handed over and there is no further way to intercept it. But you can create your own AuthenticateCallbackHandler implementation on the client that wraps the JaasClientOauthLoginCallbackHandler class, and configure yours as a login callback handler, and in that case you can intercept the handing over of the new access token, and then do with the token whatever you want.
