How to correctly configure single user configuration with https (via cert-manager)?

hello there!

im having troubles getting my nifi cluster to successfully work with single user configuration and https and was wondering if someone might be able to provide a working example configuration for this? for cotnext, i did first reference the example tls configuration in the repo but, unfortunately, it relies upon oidc for authorization.

find below my current configuration. while this configuration does result in the node running successfully, it does not correctly allow me to login with the credentials stored in the provided secret. i get the Access Unknown: Certificate and Token not found. each time i try to login.

any help/insight/suggestions would be much appreciated! thank you.

more than happy to provide whatever additional information, clarity, context, etc. that would be necessary to help troubleshoot here. appreciate the efforts you all have made on this project and know you're busy making it better! would appreciate any help I can get here when you've time.

Hmm. I think that should work. And you created the secret? If you exec into one of the nifi containers, and do tail -f logs/nifi-user.log do you see any information? Here is an example single user auth someone sent me on Slack that seems to work and has a sidecar to help troubleshoot/view the logs:
