### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version Master (and presumably all others) ### Minimal reproduce step Bug discovered while reviewing the code. Inspect the lifecycle of the [clientAuthData](https://github.com/apache/pulsar/blob/86205a9edfafb8710b24bdb0d2f1db84c5fc1926/pulsar-proxy/src/main/java/org/apache/pulsar/proxy/server/ProxyConnection.java#L100) variable. The variable is set to the last `authData` received by the client, which means that for multi-staged authentication, it is not possible to forward the authentication credentials. ### What did you expect to see? I'd expect the protocol to either support forwarding these credentials or to fail when configured to do something it is unable to do correctly. ### What did you see instead? Described above. ### Anything else? For added context, I discussed this issue here: https://github.com/apache/pulsar/pull/18130#discussion_r1080838475. ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
